18 paź 2024 · Helper T cells. Helper T cells assist other white blood cells in the immune response. They release cytokines (hormone-like signals) which stimulate: The maturation of B-lymphocytes into antibody-secreting plasma cells. The production of memory B cells. The activation of cytotoxic T cells, which destroy virus infected cells and tumour cells . An ...
12 sie 2024 · Activated T cells divide by mitosis to produce clones. Cloned T helper cells produce chemicals that activate B cells while cloned T killer cells destroy infected body cells.
26 kwi 2021 · Helper T cells stimulate B cells to proliferate and differentiate into memory B cells and plasma B cells, which secrete antibodies against invading pathogens. The antibodies circulate in the blood until they encounter their corresponding antigen and bind to form an antigen-antibody complex.
T cells are generated in the Thymus and are programmed to be specific for one particular foreign particle (antigen). Once they leave the thymus, they circulate throughout the body until they recognise their antigen on the surface of antigen presenting cells ( APCs ).
