The Birth of Functionally Distinct T Cell Subsets

The birth of functionally distinct T cell subsets.

Clonal analysis of functionally distinct human CD4+ T cell subsets

A large number of CD4+ T cell clones, obtained from peripheral blood T lymphocytes by direct limiting dilution, allowed us to address the question whether functional heterogeneity exists within the human CD4+ T cell subset. Cytotoxic capacity of cloned T cells was analyzed with the use of anti-CD3 antibodies and target cells bearing FcR for murine IgG. 6 of 12 CD4+ clones obtained were able to ...

Functionally distinct NKT cell subsets and subtypes

Natural killer T (NKT) cells are a population of autoreactive cells that mediate both protective and regulatory immune functions. NKT cells comprise several subsets of cells, but it has been unclear whether these different NKT cell subsets possess distinct functions in vivo. New studies now demonstrate that subsets of NKT cells are indeed functionally distinct and that the specific functions of...

CD94 defines phenotypically and functionally distinct mouse NK cell subsets.

Understanding of heterogeneous NK subsets is important for the study of NK cell biology and development, and for the application of NK cell-based therapies in the treatment of disease. Here we demonstrate that the surface expression of CD94 can distinctively divide mouse NK cells into two approximately even CD94(low) and CD94(high) subsets in all tested organs and tissues. The CD94(high) NK sub...

Integrin and Regulatory Foxp3 T Cells Constitute Two Functionally Distinct Human CD4 T Cell Subsets Oppositely Modulated by TNF Blockade
