Th17 cell based vaccines in mucosal immunity.

Th17 cell based vaccines in mucosal immunity. Curr Opin Immunol. 2013 May 10; Authors: Kumar P, Chen K, Kolls JK Abstract Vaccination is proven to be effective in controlling many infections including small pox, influenza and hepatitis, but strain-specific factors may limit vaccine efficacy. All of these vaccines work through the generation of neutralizing antibodies but for some pathogens there may be roles for serotype-independent immunity. Recently several groups using murine vaccine models have shown that induced T helper cell responses including Th17 responses have shown the potential for CD4+ T-cell dependent vaccine responses. Th17 mediated protective responses involve the recruitment of neutrophils, release of anti-microbial peptides and IL-17-driven Th1 immunity. These effector mechanisms provide immunity against a range of pathogens including the recently described antibiotic-resistant metallo-beta-lactamase 1 Klebsiella pneumoniae. Continued elucidation of the mechanism of Th17 responses and identification of effective adjuvants for inducing robust non pathogenic Th17 responses may lead to successful Th17 based vaccines. Here we summarize the recent advances in understanding the role of Th17 in vaccine induced immunity. We also discuss the current status and future challenges in Th17-based mucosal vaccine development. PMID: 23669353 [PubMed - as supplied by publisher]

Authors: Sugawara T, Ohkusa Y, Taniguchi K, Miyazaki C, Momoi MY, Okabe N Abstract Our earlier study investigated the incidence of severe abnormal behavior associated with neuraminidase inhibitors (NIs), but some studies have specifically examined the association of oseltamivir use and moderately abnormal behavior. Therefore, this study was undertaken to assess associations between moderately abnormal behavior and administered drugs. All cases of patients with influenza who exhibited moderately abnormal behavior were reported to us by physicians of all sentinel clinics and hospitals for influenza throughout Japan. ...

Authors: Bailey HE Abstract A severe and unusual complication found in children with influenza is an acute necrotizing encephalopathy. A 20-month-old female with no significant past medical history was admitted to our facility, presenting with a 4-day history of worsening fever, upper respiratory symptoms, new-onset altered mental status and episodes of extensor posturing. The initial concern was a dystonic reaction secondary to promethazine following a recent diagnosis of influenza A virus. A head computed tomography scan indicated concern for widespread edema, and the video EEG revealed focal slowing in the front...

CONCLUSION: Correction of the adverse events was made either using causal treatment or using symptomatic drugs. However, some drugs, in particular hematopoietic factors, have been less used due to their costs.

This article documents the first case of TSS associated with the use of a menstrual cup in a 37-year-old woman. The authors also discuss the history of TSS associated with tampon use and the mechanisms by which menstrual cups may also lead to the syndrome. Avian influenza A (H5N1) infection with respiratory failure and meningoencephalitis in a Canadian travellerSince 1997, more than 600 individuals worldwide have been infected with the poultry-originating influenza, H5N1. This report describes the first case of avian influenza A (H5N1) in the Western hemisphere in a 28-year-old woman who had just returned from a trip to Be...

We examined the interaction between the non-coxib OSU-03012 with phosphodiesterase 5 (PDE5) inhibitors to determine the role of the chaperone GRP78/BiP/HSPA5 in the response of cells. Sildenafil (Viagra) interacted in a greater than additive fashion with OSU-03012 to kill tumor cells including stem-like and anoikis resistant cells. Treatment of cells with OSU-03012/sildenafil: abolished the expression of growth factor receptors and plasma membrane drug efflux pumps; and caused a more rapid degradation of GRP78 and of other important chaperone proteins e.g. HSP27, HSP40, HSP60, HSP70 and HSP90. Decreased expression of recep...
