Immunosenescence is marked by a progressive decrease in the number of naive cells and an increase in the number of memory cells showing poor functionality. The differentiation of T cells toward a senescent phenotype is characterized typically by clonal expansion of CD8+ T lymphocytes that lack ...
T cells follow a distinct process of activation, proliferation, and differentiation. However, in settings of chronic infection, autoimmunity, and cancer, they can subsequently become functionally and phenotypically exhausted. T cell exhaustion (Tex) is a blanket term that covers a compromised function ...

By the use of Ly antisera and complement it is possible to remove subpopulations of mouse T cells from spleen cell suspension. It is shown that these Ly antisera are specific for the Ly alleles carried by the cells. Helper cells from primed or unprimed mice and cells which respond to Con ...
During chronic hepatitis C virus (HCV) infection, both CD4+ and CD8+ T-cells become functionally exhausted, which is reflected by increased expression of programmed cell death-1 (PD-1) and T-cell immunoglobulin and mucin domain-containing protein 3 (Tim-
Due to difficulties in assessing the TCR avidity in polyclonal population of T cells, it is currently not known whether high avidity T cells preferentially survive in aging individuals, and what impact this might have on the function of the immune system and development of autoimmune diseases. ...
Activated T cells were expressed as a percentage of the total of CD3-positive cells. CD25, CD26, CD40L, and CD69/CD3 percentages increased with the severity of the coronary syndrome. In patients with AMI all percentages were significantly higher than in patients with chronic stable angina. ...
