T cell - Wikipedia
T cells are one of the important types of white blood cells of the immune system and play a central role in the adaptive immune response. T cells can be distinguished from other lymphocytes by the presence of a T-cell receptor (TCR) on their cell surface. T cells are born from hematopoietic stem cells, [1] found in the bone marrow.

T cells are a type of white blood cell that help your immune system fight germs and protect you from disease. There are two main types: cytotoxic and helper T cells.

2018年2月20日 · We will discuss these multiple aspects of human T cell responses, beginning with T cell development, the role of naive and regulatory T cells, differentiation to effector and memory subsets, and how tissue localization impacts T cell function and maintenance.
T Cell-Mediated Immunity - Immunobiology - NCBI Bookshelf
The activation of naive T cells in response to antigen, and their subsequent proliferation and differentiation, constitutes a primary immune response. At the same time as providing armed effector T cells, this response generates immunological memory, which gives protection from subsequent challenge by the same pathogen.
