Naive ot-ii t cells
In immunology, a naive T cell (Th0 cell) is a T cell that has differentiated in the thymus, and successfully undergone the positive and negative processes of central selection in the thymus. Among these are the naive forms of helper T cells (CD4 ) and cytotoxic T cells (CD8 ). Any naive T cell is … Zobacz więcej Naive T cells are commonly characterized by the surface expression of L-selectin (CD62L) and C-C Chemokine receptor type 7 (CCR7); the absence of the activation markers CD25, CD44 or CD69; and the … Zobacz więcej • Immune system • Memory T cells Zobacz więcej Naive T cells can respond to novel pathogens that the immune system has not yet encountered.
