usually phytohaemagglutinin (PHA) is an good stimulator of t-cell proliferation.
Macrophages stimulate the production of other lymphocytes. They are produced by the differentiation of monocytes in tissues.
False - They stimulate maturation of T lymphocytes after they leave the thymus and migrate to other lymphatic tissue.
Mononucleosis is caused by a proliferation of lymphocytes caused by the Epstein-Barr Virus.
Platelet-derived growth factor (PDGF) is a chemical that stimulates mitosis in healing wounds. It is released by blood platelets and other cells at the wound site to promote cell division, proliferation, and tissue repair.
No. Thymosin stimulates the development and differentiation of T lymphocytes. They also regulate immune system by stimulating other kinds of immune cells.
The hormone that stimulates lymphocyte activity is interleukin-2 (IL-2), which is produced by activated T cells. IL-2 plays a crucial role in regulating the growth, proliferation, and differentiation of T cells and other immune cells involved in the immune response.
When an antigen stimulates B or T cells, these cells can produce identical lymphocytes through a process called clonal expansion. This results in a large population of identical cells that are all capable of recognizing and responding to the specific antigen that initiated the immune response.
The toxin binds directly to proteins on target cells, subsequently stimulating the proliferation of large number of T lymphocytes.
The Treg cell that inhibits the activity of B and T lymphocytes is called the CD4+ regulatory T cell, specifically the FOXP3+ subset. These cells play a crucial role in maintaining immune tolerance and preventing autoimmune responses by suppressing the activation and proliferation of other immune cells, including B and T lymphocytes. They achieve this through various mechanisms, including the secretion of inhibitory cytokines and direct cell-to-cell contact.
Bone marrow produces lymphocytes and monocytes and all other blood cells.
The endometrium is built up by the hormone estrogen during the first half of the menstrual cycle. Estrogen stimulates the growth and proliferation of the endometrial cells and blood vessels.
T- lymphocytes are the "Generals of the immune system" and direct much of the immune response. Their biggest role is in telling B lymphocytes to make antibodies but they also have other functions.
