In humans, the Fc receptor for IgG, FcgammaRIIA, is expressed on macrophages and platelets and may play an important role in the pathophysiology of immune-mediated thrombocytopenia. Mice lack the genetic equivalent of human FcgammaRIIA. To better understand the role of FcgammaRIIA in vivo, FcgammaRIIA transgenic mice were generated and characterized. One transgenic mouse line expressed FcgammaR...

IFN-gamma is critical in the immune response to mycobacterial infections, and deficits in IFN-gamma production and response have been associated with disseminated nontuberculous mycobacterial infections. Mutations in the IFN-gamma receptor ligand-binding chain (IFNgammaR1) have been shown to confer susceptibility to severe infection with nontuberculous mycobacteria. However, mutations in the IF...

Cytokines have been shown to be powerful regulators of the immune response. In this study, we analyze the effect that the newly recognized cytokine interleukin (IL)-15 has on proliferation and cytokine induction using peripheral blood mononuclear cells (PBMCs) and purified CD4+ T cells from patients infected with human immunodeficiency virus (HIV) who are at various stages in their disease. We ...

AIMS To determine whether aortic adventitial chronic inflammation associated with advanced atherosclerosis ("chronic periaortitis") is associated with any detectable cytokine gene expression. METHODS RNA was extracted from six fresh surgical specimens of atherosclertic aortic aneurysm wall showing a spectrum of chronic periaortitis. Controls included four normal aortas and an HUT 78 T cell li...

Results The mutation detected was a defect of the common gamma chain of the interleukin 2 receptor (IL2Rg). Even though genetic counseling advised otherwise the patient’s mother got pregnant during follow-up and as no compatible donor was found we chose to wait birth and verify compatibility. Genetic evaluation of the newborn revealed the absence of the IL2Rg gene defect in blood cord and a mat...

CD132 is the common gamma chain to a number of cytokine receptor complexes including that for IL-2. To identify the functional domain of chicken CD132 (chCD132), the cDNA of chCD132 was cloned, and a neutralizing monoclonal antibody, raised against a recombinant chCD132 protein, was identified by inhibition of IL-2-dependent proliferation of T cells. Flow cytometry analysis revealed that chCD13...

There have been two previous conflicting reports that the development of T-cell-mediated autoimmune diabetes (type 1 diabetes) was respectively unaffected or inhibited in NOD mice genetically deficient in the T-helper (Th) 1 cytokine interferon (IFN)-gamma or the alpha-chain subunit of its receptor. Our goal was to resolve this conundrum by congenically transferring, from a 129 donor strain to ...

background: there is evidence that cd36 promotes foam cell formation through internalizing oxidized ldl (ox-ldl) into macrophages therefore, it plays a key role in pathogenesis of atherosclerosis. in addition, cd36 expression seems to be mediated by nuclear receptor peroxisome proliferator-activated receptor gamma (ppar-γ). the aim of the present study was to evaluate and compare the effect of ...
