However it was not fully investigated that how reserve capacity of single kidney for healthy kidney donor changes after unilateral nephrectomy. The aim of this study was to assess the change of remaining single kidney function after kidney donation and evaluate predictive pre-donation factor for reserved single

kidney capacity in donors. Methods: Total 74 kidney donors who underwent 99mTc-DTPA Scintillation-Camera renography before and after kidney donation were included in this study. The renography measured singl-kidney glomerular filtration rate (sk-GFR) of both kidney before donation and post-donation GFR of remaining kidney during 12 months in donor. We investigated the factors that are associated with reserved capacity of remaining single kidney after donation, such as age, BMI, BSA, serum creatinine for Cock-Croft Gault’s fomula and MDRD GFR, 24 hr urine collection for creatinine clearance https://www.selleckchem.com/products/dorsomorphin-2hcl.html and kidney volume measured by abdomen CT. Results: After uninephrectomy the mean of serum creatinine increased significantly

(P = 0.000, Romidepsin datasheet from 0.77 to 1.07 mg/dL) and the mean measured GFR by the renography declined (P = 0.000, from 112.9 to 74.9 ml/min/1.73 m2). Nevertheless the mean of serum creatinine and mGFR was stabilized during 12 months follow-up period (mGFR at Post-donation, P = 0.165 [6 month 74.9 ± 18.2 vs 12 month 81.4 ± 14.8 ml/min/1.73 m2]). The sk-GFR of remaining kidney significantly increased by 33.6% after uninephrectomy (sk-GFR, P < 0.01 [Pre-nephrectomy 57.9 vs Post-nephrectomy 77.5 ml/min/1.73 m2]). By univariate linear regression BMI, total mGFR, sk-GFR of remaining kidney and total kidney volume at pre-donation was included as independent predictors of change of sk-GFR. Among these, BMI (P = 0.013) and sk-GFR of remaining kidney at pre-donation (P = 0.019) was statistically related to reserved single kidney capacity in multivariate regression analysis. Conclusion: After kidney donation, reserved single kidney capacity showed Protirelin significant increase due to adaptive hyperfiltration, especially more compensatory

response in donor with lower BMI and sk-GFR of remaining kidney at pre-donation.

However, there is little information about the clinical significance of lymphatic vessels in kidney allograft.

To test this hypothesis, immunized mice were treated with an agonistic anti-GITR

mAb to disrupt the suppressive activity of Treg cells.48–50 Splenic GCs persist for at least 4 weeks so the GC response was monitored at days 8, 12, 18 and 24 post-challenge. Preliminary experiments tested the effects of continuous anti-GITR mAb injections on the GC response. When injected twice weekly for up to 4 weeks, however, anti-GITR mAb administration resulted in a high death rate in immunized mice, preventing an appropriate kinetic analysis (data not shown). Similar to previous studies18,22,23,26 a three-injection PLX4032 nmr protocol was therefore used whereby 250 μg of either anti-GITR mAb or control rat IgG (rIgG) was injected on days −2, +1 and +5. Mice were immunized with SRBC on day 0 and splenic GCs were analysed during the ensuing 4 weeks. Naive mice kept in specific pathogen free conditions do not have detectable GC B cells in their spleens, as previously described1,5 and C59 wnt datasheet shown in Fig. 1(a). Upon challenge with SRBC, a robust GC response is induced and easily detected as a B220+ PNAhi population (refs. 1,5 and Fig. 1a). Using a multi-colour approach, the IgM+ (non-switched)

B cells and switched GC B cells can be further delineated (Fig. 1a). When comparing the GC response from immunized mice injected with anti-GITR mAb or rIgG, it is clear that Treg-cell disruption resulted in a higher frequency and total number of splenic B220+ PNAhi GC B cells at all time-points out examined

(Fig. 1b). As expected, the ratio of IgM+ to switched GC B cells remained steady over the course of the response in control rIgG-treated mice, even as the reaction waned (Fig. 1c). However, immunized mice treated with anti-GITR mAb exhibited a higher frequency and total number of IgM− switched GC B cells at day 8, an imbalance which increased over time (Fig. 1c). When comparing the distribution of IgG isotypes expressed on switched GC B cells in anti-GITR mAb and rIgG treated mice, a significant increase in the percentage of IgG1+ GC B cells was observed at day 8 in the Treg-cell-disrupted group (data not shown). At all other time-points, IgG isotype expression within the switched GC pool did not differ between the two groups. Taken together, disruption of Treg cells led not only to a larger GC response, but to an inability to control the proportion of IgM+ to switched GC B cells. Given the marked changes observed in splenic GC B cells after Treg-cell disruption, the non-GC (B220+ PNAlo/neg) B-cell population was also monitored. As shown in Supplementary material, Fig. S1(A), a significant difference in the total number of non-GC B cells was observed after anti-GITR mAb treatment only at day 12 post-challenge. To assess which non-GC B-cell sub-sets were affected at day 12, a detailed analysis of follicular, pre-marginal zone, marginal zone, transitional 1 (T1), T2 and B1 B cell percentages was performed (see Supplementary material, Fig. S1B,C).

After selection with G418 we performed

PCR screening (PCR: 5-tcaacctacaaacggaaagaa and 5′-ctaaacccaaacacagaccta). As a PCR control we cloned a similar genomic fragment of the IgG1 region in front of IgE. The test-arm fragment was 155 bp longer, as the actual target vector region, in order to avoid PCR contaminations (Supporting Information Fig. 4). The expected PCR size for controls is 1050 bp and for correct integration of the target vector is 895 bp (Supporting Information Fig. 4). Then, we verified positive clones by southern blots using an external genomic probe (Fig. 1A). Three independent positive clones were injected and chimeric offspring was bred to Deleter mouse strain on the 129Sv genetic background [42]. Testing of the Cre-deletion was done using the primers:

5′-atgggagtttctgtgattct Selleck FK506 and 5′-gcccagaaggataagaaaac for the IgE knock-in (PCR-B, 590 bp) (Fig. 1A). After Cre deletion backcrossing for nine generations to C57BL/6 was performed. Some of these mice were then mated to CD23-deficient mice [23] on a C57BL/6 background. All studies with mice were performed in accordance with German animal experimentation law. Immunoglobulin isotype-specific ELISA was done using goat anti-mouse immunoglobulin anti-sera (Southern Biotech, USA) except for IgE detection, which was done with monoclonal anti-IgE antibodies 84.1C and EM95.3 [43, 44] and total murine IgG, which was done by goat anti-mouse IgG (Jackson, USA). For antigen-specific find more ELISAs, we coated with 10 μg/mL TNP-OVA. We used pooled sera

from immunized mice as a standard and titrated the samples in serial dilutions and gave the titers of specific Igs as relative Units/mL. Anti-CD23 (B3B4, BD Biosciences, USA), anti-CD45RB-B220, anti-IgG1 (Clone A85-1, BD or RMG1-1, Biologend) and anti-IgE (Clone23G3, BD; or EM95.3) FITC and PE-labeled antibodies were used in FACS analysis on cells that have been preincubated with mouse IgG as Fc block (Jackson Immuno Research, USA) on a FACScalibur (BD Biosciences, USA). For the detection of surface IgE and IgG1 after N. brasiliensis infection, mesenteric lymph node cells were prepared by mechanical disruption in 70 μm cell strainers (BD Falcon) and washed with an acid buffer (0.085 M NaCl, 0.005 Epothilone B (EPO906, Patupilone) M KCl, 0.01 M EDTA, and 0.05 M NaAcetate (pH 4)) to remove extrinsic IgE bound to CD23. For the detection of mouse mast cell protease-1 (MMCP-1) in plasma of anaphylactic mice, we used an ELISA kit (eBiosciences, USA) according to the manufacturer. In vitro antibody production was examined in total spleen cells stimulate with 20 μg/mL LPS, with and without IL-4 (Peprotech, USA) for 4–5 days. For antigen-specific immune response 3-month old mice were sensitized by injection with 100 μg TNP-OVA (Biosearch Technologies, USA), precipitated with alum (Serva, Heidelberg, Germany), subcutaneously and i.p. After 14 days mice received a similar booster injection.

During the last decade, monoclonal antibodies targeting these have been tested in clinical trials. Specific therapy targeted against tumour necrosis factor (TNF)-α alone using anti-TNF-α mAbs or soluble TNF-α receptors has been effective in murine collagen-induced arthritis (CIA) by reducing the incidence and severity of disease [16]. Recent studies have shown that therapy with rituximab is one of selleck kinase inhibitor the treatment options for optimizing RA therapy [17]. Furthermore, mAbs directed against this CaMBP gives a promising result in the AIA model, which is

a reliable model for RA because it mimics exactly RA of the human joint [18]. In the present study, our data indicate that 67 kDa protein isolated from SF of RA patients is rheumatoid factor (RF), which is calcium-binding in nature and mediates the inflammatory and destructive process in RA. Monoclonal antibody for novel angiogenic protein (NAP) was produced and the same was used to explore the synergistic role of VEGF and NAP to evaluate the relationship of these proteins in RA. We also studied the correlation of important angiogenic markers CD31, an endothelial cell proliferation indicator, and fms-like tyrosine kinase (Flt1), the receptor for VEGF in AIA and the NAP-induced arthritis (NIA) model. Using enzyme-linked immunosorbent assay (ELISA) and immunohistochemical studies we found that a high level of VEGF is expressed with increased microvessel density

(MVD) in RA. Monoclonal antibodies directed against NAP ameliorate the disease incidence in NIA and an established AIA EPZ-6438 in vivo rat model. Our studies indicated that anti-NAP mAbs have a potent anti-arthritic effect which targets angiogenesis and can be useful for individualization of therapeutic strategies in treatment of mafosfamide RA. Patients who fulfilled the American College of Rheumatology

criteria for RA [19] were recruited from the out-patient Department of Pathology, JSS Hospital, Mysore, with the approval of the medical college ethics committee and as per the guidelines of the Institutional Review Board. Informed consent was obtained from all the patients. The patient group comprised seven women and three men, with an age range of 38–67 years. Patients had active disease and disease duration of ≤ 2 years. All knee joints demonstrated signs of active synovitis at the time of aspiration. Wistar rats (aged 4–5 months) were obtained from the central animal facility of the Department of Zoology, University of Mysore, Mysore, India. All the animal experiments were approved by the Institutional Animal Ethics Committee, University of Mysore, Mysore and studies were conducted according to the guidelines of the Committee for Purpose of Control and Supervision of Experiments on Animals (CPCSEA), Government of India, India. Novel angiogenic protein was isolated and purified from human SF of patients with RA, as per the method described previously by us [20].

, 2005). Similar analysis has been performed on another model biofilm-producing strain, S. aureus MN8m (Vinogradov et al., 2006). There,

the EC-TA was found to be composed of phosphate, ribitol, glycerol, GlcNAc, and Ala. Likewise, for several clinical strains studied, the TA was always present in their extracellular biofilm matrix (Kogan et al., 2006; Sadovskaya et al., 2006). All these data confirmed that the EC-TA was an important and permanent component of the staphylococcal biofilm matrix. It could be suggested that, because, in a number selleck inhibitor of Gram-positive strains, part of the CW-TA is located in a ‘fluffy’-layer region beyond the cell wall (Neuhaus & Baddiley, 2003), some of the TA would be released from the cell surface into the extracellular space and thus becomes a part of the extracellular matrix (Kogan et al., 2006). Surprisingly, the chemical structures of the staphylococcal TAs, especially the pattern of d-Ala substitution – an important element for the pathogenecity of this

microorganism – have not been elucidated in detail. As a subsequent step of the investigation, we elucidated the chemical structures of the TAs of two model biofilm-producing strains –S. epidermidis RP62A and S. aureus MN8m. The chemical structure of CW-TAs of S. aureus and S. epidermidis is known thanks to the pioneer studies of Baddiley and colleagues in the 1960s and 1970s. These studies have shown that the TA of S. aureus was a (1,5)-linked poly(ribitol phosphate), substituted in position 4 of the ribitol residue with a β-GlcNAc (Fig. 1a; Baddiley et al., 1961, 1962a, b). The lipoteichoic acid

of S. aureus was a (1,3)-linked Smad inhibitor poly(glycerol phosphate), attached to the diacylglycerol lipid anchor via a diglucosyl (gentobiosyl) unit (Fig. 1b; Duckworth et al., 1975). The CW-TA of S. epidermidis I2 was also a (1,3)-linked poly(glycerol phosphate), containing β-Glc and d-Ala residues (Fig. 1c; Archibald et al., 1968). Later, Endl et al. (1983) analysed the composition Branched chain aminotransferase of the CW-TAs of several strains of S. aureus and CoNS; however, the detailed structures or the pattern of d-Ala substitution have not been studied. The structures of TAs of both model strains were elucidated using chemical methods, MS, and NMR spectroscopy. It was found that EC and CW TAs of S. epidermidis RP62A had the same structure of (1,3)-linked poly(glycerol phosphate), substituted at the 2-position of glycerol residues with α-Glc, α-GlcNAc, d-Ala, and most interestingly, α-Glc6Ala (Fig. 1d; Sadovskaya et al., 2004). Both EC and CW TAs from S. areus MN8M were composed of two different polymeric chains: a poly(ribitol phosphate) and poly(glycerol phosphate). In the poly(ribitol phosphate) chain, nearly 100% of ribitol was substituted with β-GlcNAc at position 4, and the structure corresponded to the one described in the literature for S. aureus H (Baddiley et al., 1961). Glycerol residues were (1,3)-linked.

Thereafter, she became bedridden, and breathing was assisted through a tracheostomy for 12 years. She died at

the age of 82 after 18 years from the initial symptom. Post mortem examination revealed severe neurodegeneration in the inferior olive, pontine nuclei, substantia nigra, locus ceruleus, putamen and cerebellum. Notably, phosphorylated α-synuclein (p-α-syn)-positive GCIs were found in these areas, but their number was very low. In contrast, the density of GCIs was much higher in such regions as the tectum/tegmentum of the brainstem, pyramidal tracts, neocortices and limbic system, which usually contain a small number of GCIs. Another constituent of GCIs, ubiquitin (Ub) and Ub-associated autophagy substrate p62, were also positive

in some GCIs, and distribution of Ub/p62 immunoreactivity was proportionate to Talazoparib purchase that of p-α-syn+ GCIs despite the very long duration of the disease. Furthermore, this case had complicated hypoxic encephalopathy, but p-α-syn+ GCIs were also found in the damaged white matter, indicating the contribution of α-syncleinopathy as well as hypoxic effect to the secondary myelin and axonal loss in the white matter. Together, this rare case suggests the contribution of the disease duration to the prevalence of GCIs, and the possible involvement of the limbic system in extensive-stage Enzalutamide in vivo disease. “
“Ubiquilin-1 acts as an adaptor protein that mediates the translocation of polyubiquitinated proteins to the proteasome for degradation. Although previous studies suggested a key role of ubiquilin-1 in the pathogenesis of Alzheimer’s disease (AD), a direct relationship between ubiquilin-1 and Hirano bodies in AD brains remains unknown. By immunohistochemistry, we studied ubiquilin-1 and ubiquilin-2 expression in the frontal cortex and the hippocampus of six AD and 13 control cases. Numerous Hirano bodies, accumulated

in the hippocampal CA1 region of MTMR9 AD brains, expressed intense immunoreactivity for ubiquilin-1. They were much less frequently found in control brains. However, Hirano bodies did not express a panel of markers for proteasome, autophagosome or pathogenic proteins, such as ubiquilin-2, ubiquitin, p62, LC3, beclin-1, HDAC6, paired helical filament (PHF)-tau, protein-disulphide isomerase (PDI) and phosphorylated TDP-43, but some of them expressed C9orf72. Ubiquilin-1-immunoreactive deposits were classified into four distinct morphologies, such as rod-shaped structures characteristic of Hirano bodies, dystrophic neurites contacting senile plaques, fragmented structures accumulated in the lesions affected with severe neuronal loss, and thread-shaped structures located mainly in the molecular layer of the hippocampus. Ubiquilin-1 immunoreactivity is concentrated on Hirano bodies and dystrophic neurites in AD brains, suggesting that aberrant expression of ubiquilin-1 serves as one of pathological hallmarks of AD.

Thus, it would be unreasonable to expect a stronger effect (in other words, after onset of diabetes) in humans. Secondly, no preclinical study ever tested the clinical GAD-Alum preparation, and no efficacy was noted in our recent studies in NOD and B6 diabetes models (Pagni, Boettler and von Herrath, unpublished). 3-deazaneplanocin A Again, it is probably unreasonable to expect an antigenic formulation to work in humans when it does

not even prevent diabetes in otherwise permissive animal models. Several other theories have been proposed to account for the failure of GAD-Alum in humans, including the lack of GAD expression in β cells; this is a controversial area, as many studies have demonstrated expression of GAD-65 and 67 proteins in murine and human β cells [36]. Lastly, one could ask whether the dose of GAD-Alum was sufficient – as most patients mounted a clearly detectable immune response, this appears less likely. However, alum might have been a suboptimal adjuvant for an ASI, as the resulting mixed but T helper type 2 (Th2)-dominated cytokine response of induced GAD-reactive T cells (Arif, Selleckchem Cetuximab Roep and Peakman, unpublished) did not result in protective cell populations. In the absence of a functional mouse model of GAD-Alum preventing diabetes, it will be difficult at this point to clarify these issues. The question of the antigenic dose might have more bearing on the

issue of efficacy with oral insulin [15]. As predicted from animal models [37], prophylactic oral ioxilan insulin given at a daily dose of 7·5 mg had a very marginal effect in preventing diabetes in individuals at high risk (exhibiting multiple autoantibodies [38-41]), but not in any other patient groups. However, as has been evident from multiple studies in different mouse models, oral insulin dosages have to be comparatively

much higher to induce optimal disease preventive effects, which are seen at a dose of 1 mg given twice per week [42]. This dose would equate to approximately 1 g of oral insulin twice per week in humans. In addition, it is likely to be necessary to provide the drug in enteric-coated capsules, without which > 99·99% of the insulin is lost through digestion in the stomach and only minimal amounts of intact antigen or some peptides will reach the lower gut and the Peyer’s patches, the location at which oral insulin has been shown to induce its desired immune-regulatory response. Therefore, more precise dose calculations should have probably preceded the oral insulin trial and its current follow-up study. A further human/mouse mismatch relates to the overall management of expectations when devising trials for ASI. In rodent studies most, if not all, ASI is effective only for early and, at best, late prevention of disease, but never after onset of hyperglycaemia. Thus, we should not expect antigens to reverse human diabetes or even preserve C-peptide after onset (at least with effects detectable in reasonably sized studies); and this has indeed been the case.

Tunica vaginalis testis (pars parietal) is another tissue donor site that has the capability of being used both as flap and free graft.

In clinical practice, it has usually been used as a second layer for augmentation in a tabularized incision plate (TIP) in order to prevent subsequent urethrocutaneous fistula formation.[5] Also it has been used for correction of penile cuvature (chordee)[6] and surgical treatment of Peyronie’s disease.[7] Many experimental studies[8-12] and a few clinical studies[13, 14] have reported the feasibility and usefulness of using tunica vaginalis for definitive urethroplasty in anterior urethral strictures. The majority of those experimental studies find more have revealed that tunica vaginalis mesothelium was gradually replaced by a more stratified epithelial lining similar to the urethral lining of the native urethra. In the current study, we retrospectively evaluated the clinical efficacy and feasibility of tunica vaginalis (TV) pedicle flap for reconstruction of anterior urethral stricture by comparing some clinical

parameters including the urinary flow rate (Qmax), international prostate symptom score (IPSS), patients quality of life (QoL) and residual urine (RU). The pre-operative result was compared 3 and 12 months postoperatively. Obeticholic Acid After obtaining institutional ethical review board approval, 15 male patients who had undergone Tunica vaginalis pedicle flap urethroplasty between January 2006 and January 2011, were retrospectively assessed. The procedure was allocated for patients who had not enough penile skin, including those who had previous

failed attempts of urethroplasty and those who had already underwent circumcision. Before surgery, the length of stricture was determined according to radiology reports and conventional retrograde urethrography plus voiding cystourethrography. During surgery, it was measured, using centimeter ruler. The urethroplasty had been done with two different techniques: TV pedicle flap ventral on lay urethroplasty (nine patients), and TV pedicle flap tubularized Lepirudin substitution urethroplasty (six patients). In order to assess the clinical efficacy and success rate of the surgical technique, the pre-operative Q(max), IPSS, QoL, RU were compared with them 3 and 12 months postoperatively. In order to know if there was change in caliber of urethra over time, the comparison was done between them at 3 and 12 months postoperatively. The t-test was used for statistical analysis. Moreover, pre-operative and postoperative retrograde urethrography was compared (Figs 1, 2). Van Buren urethral sounds (16–18 Fr) were used for checking and dilating the reconstructed part at 3 month intervals after surgery. Finally, Fisher’s exact test was used to find any difference between success rates of two aforementioned surgical techniques. Under epidural anesthesia the patient was placed in the lithotomy position.

The severity was assessed based on apnea hypoapneaindex(AHI). All CKD patients attending the outpatient department from January 2012 to July 2013 were assessed using Cockroft and Gault formula and assigned in either of the two groups based on the GFR. Results: A total of 647 patients were screened learn more and 302(46.67%) patients were in stage 2,3 and 4 of CKD. 87(28%) among the 302 were at high risk for berlin questionnaire). 37(42.5%) patients among the 87 patients were excluded based on the exclusion criteria. 50 patients underwent split night

sleep study, polysomnography testing. The prevalence of obstructive sleep apnea was found to be 28% after screening the population with Berlin questionnaire. The incidence of obstructive sleep apnea was found to be 25.4% in the Berlin questionnaire positive CP 690550 after polysomnography. The Mann Whitney U-test statistics was applied and astatistical significance (p < 0.05) between Early and Late CKD with respect to AHI and ODI was observed. An improvement in the Late CKD is observed and the Z values for AHI and ODI were 4.273 and 2.307respectively which was statistically significant. Conclusion: This is the first study in South Indian population to assess the prevalence of obstructive sleep apnea

in non dialysis chronic kidney patients. This study indicates the necessary to screen the Non dialysis CKD population for obstructive sleep apnea. Further studies with large sample sizes are needed to re-establish the increased risk of OSA associated with decline in creatinine clearance among the study Nintedanib (BIBF 1120) population.

TATSURU, CHANG WENXIU, UCHIDA SHUNYA Department of Internal Medicine, Teikyo University School of Medicine Introduction: With the progress of renal dysfunction, ultrasonographic findings showed morphological alterations such as the increased brightness of the kidney cortex and the kidney atrophy. However, the detailed relationships between the biochemical changes and morphological changes in CKD remain to be clarified. In the present study the association of ultrasonographic findings with the degree of kidney damages was investigated by use of morphometric analyses. Methods: 1,320 CKD patients that visited Nephrology department of our hospital from June, 2010 to March, 2012 were screened. Patients with preexisting morphological diseases such as congenital anomaly, nephrectomy and polycystic kidneys, etc. were excluded. 156 CKD patients that received both the kidney ultrasonography and biochemical examination at the same occasion were enrolled for the analysis. The kidney function was evaluated by eGFR. The morphological findings examined in the study were the length of the long and short axes of the both kidneys, cortical thickness and echogenicities of the kidney cortex.

Therefore, it is possible that these healthy individuals had been exposed to Mtb in their lifetime, and that this had caused the high production of IFN-γ after stimulation in vitro with PPD and H37Ra. More normal healthy individuals from non-endemic TB areas who have been confirmed negative CHIR-99021 mw by chest X-ray and TST, and tested for latent TB infection and infection manifesting as active TB by IGRAs, should be included in future studies. IFN-γ is produced from T cells (both CD4+

and CD8+T cells) and NK cells and activates bactericidal mechanisms in macrophages (3). It has been demonstrated that during the course of chronic and fatal TB infection, CD4+ T cells are absent even though CD8+ T cells can produce large amounts of IFN-γ. This supports the hypotheses that CD4+ T cells have important, non redundant roles in control of Mtb in addition to IFN-γ production, that CD4+ T cells assist in the development of cytotoxic CD8+ T cell populations and that the cytotoxicity exerted by effector LY294002 ic50 CD8+ T cells might be an important component of anti-mycobacterial immunity (22). The present results indicate that patients with newly diagnosed and relapsed TB have low circulating granulysin but high IFN-γ concentrations before anti-TB therapy, suggesting that granulysin and IFN-γ may act in concert or in synergy in host defense against Mtb infection. In conclusion,

patients with active pulmonary TB have low circulating granulysin but high IFN-γ concentrations before treatment indicating their possible role in controlling M. tuberculosis infection. We wish to thank the staff of the TB/HIV Research Project, a collaborative research

“The pattern of immune response to a vaccine antigen can influence both efficacy and adverse events. Th2-cell-deviated responses have been implicated in both human and murine susceptibility to enhanced disease following formalin-inactivated (FI) vaccines for measles and RSV. In this study, we used the Th2-cell-deviated murine model of FI-RSV vaccination to test the ability of a dominant negative, cell-penetrating peptide inhibitor of STAT6 (STAT6 inhibitory peptide (IP)) to modulate the vaccine-induced predisposition to exaggerated inflammation during later RSV infection.
