Diameter of t cell
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, found in the bone marrow. Dev… WebThe TCR (T-cell receptor) is a complex of integral membrane proteins that participate in the activation of T-cells in response to an antigen. Stimulation of TCR is triggered by MHC (major histocompatibility complex) molecules on cells with the antigen. Engagement of the TCR initiates positive and negative cascades that ultimately result in ...
