T Cells: Types and Function - Cleveland Clinic
2023年1月17日 · 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.
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 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.

Histology, T-Cell Lymphocyte - StatPearls - NCBI Bookshelf
2023年5月1日 · CD8+ T cells, also known as killer T cells (or cytotoxic T cells), are effector cells for cell-mediated immunity. Initially, CD8+ T cells are naive and must be activated to begin effector functions (i.e., immune functions).
T cells are crucial for immune functions to maintain health and prevent disease. T cell development occurs in a stepwise process in the thymus and mainly generates CD4 +and CD8 T cell...
