background: type 2 diabetes (t2d) is a chronic metabolic disorder in which beta-cells are destroyed. the islet amyloid polypeptide (iapp) produced by beta-cells has been reported to influence beta-cell destruction. objective: to evaluate if iapp can act as an autoantigen and therefore, to see if cd8 + t-cells specific for this protein might be present in t2d patients. methods: peripheral blood ...

conclusions the cd4+ and cd8+ tcr vβ gene families undergo clonal expansion in cshb patients, and cd8+ t cells play a major role in the pathogenesis of cshb. moreover, the conserved motifs and limited use of joining region genes observed in the cshb patients of this cohort indicated that similar antigenic epitopes are recognized. results the number of oligoclonal or monoclonal expansion tcr vβ ...

Background: Cytotoxic CD8+ T cells, as essential parts of the adaptive immune system, play pivotal roles in anti-tumor immune responses. It is well documented that cytokine expression profiles and activation status of these cells during anti-tumor immune responses affect the outcome of host-tumor interaction. Objective: To investigate the percentages of CD8+ lymphocytes and their subsets in...

The development of cellular immune responses in primary human immunodeficiency virus type-1 (HIV-1) infection is accompanied by a dramatic decrease in plasma viremia and resolution of the acute clinical syndrome. The full nature of the immunological response and its consequences on HIV pathogenesis is still largely a mystery, but significant progress has been achieved in the characterization of...

Background: CD8+ cytotoxic T lymphocytes have been recently divided based on their cytokine expression profile. Objective: To evaluate the percentages of CD8+ lymphocytes and their effector subsets including Tc1, Tc2 and Tc17 in the tumor draining lymph nodes (TDLNs) of patients with breast cancer. Methods: Single cell suspensions were obtained from TDLNs of 42 patients with breast cancer. Stai...
