t Cross-sectionall studies were conducted to measure soluble viral and immunologicall markers in plasma in order to determine the prognostic value of thesee markers for HIV disease progression in Ethiopians and to see their associationn with cell surface markers in HIV-1-infected and -non-infected Ethiopians.. Whole blood samples were collected from 52 HIV-1-negative Ethiopians;; 32 HIV-1-posit...
cumulating evidence points to a key role for cd8+ t cells in the pathogenesis of multiple sclerosis.cd8 expression level was believed to be present constantly on the surface of human peripheral blood t cells. however, it was shown that peripheral blood lymphocytes may be divided by the level of cd8 expression, into cd8+high and cd8+low t cells. now it is well established that the cd8low populat...
Most of the cells found in lung parenchyma in patients with idiopathic pulmonary fibrosis are activated T lymphocytes and macrophages. The serum levels of three markers of cell mediated immunity were measured in 20 patients with idiopathic pulmonary fibrosis, in 20 normal subjects and in 12 patients with sarcoidosis to evaluate their clinical and prognostic significance in idiopathic pulmonary ...
The presentation of exogenous protein antigens in a major histocompatibility complex class I-restricted fashion to CD8+ T cells is called cross-presentation. We demonstrate that cross-presentation of soluble viral antigens (derived from hepatitis C virus [HCV], hepatitis B virus [HBV], or human immunodeficiency virus) to specific CD8+ T cell clones is dramatically improved when antigen-presenti...
The CD8 coreceptor plays a crucial role in both T cell development in the thymus and in the activation of mature T cells in response to Ag-specific stimulation. In this study we used soluble peptides-MHC class I (pMHC) multimeric complexes bearing mutations in the CD8 binding site that impair their binding to the MHC, together with altered peptide ligands, to assess the impact of CD8 on pMHC bi...
OBJECTIVE Studies exploring the immunologic effects of maraviroc (MVC) have produced mixed results; hence, it remains unclear whether MVC has unique immunologic effects in comparison with other antiretroviral drugs. We sought to determine whether MVC has differential effects compared with tenofovir disoproxil fumarate (TDF) during initial antiretroviral therapy. DESIGN Prospective study in AI...
