What does T in T cells stand for?
The T in T-cells stands for the thymus gland. Lymphocytes produced in the bone marrow are either become B-cells or they are matured in the thymus gland and are "trained" to be either Natural Killer T-cells, CD4 (Helper T-cells), CD8 (Suppressor T-cells).
What does the t cells and b cells do?
B cells stand for Bursa of Fabricus and T cells stand for T-lyphocytes.
Are cytotoxic T cells a type of T cell clone?
Yes, cytotoxic T-cells are a subset of T-cells that in contrast to helpter T-cells express CD8.
How are helper t cells activated?
It is a type of leukocyte, or white blood cell, but it has no ability to ingest or destroy invading bacteria. It activates other white blood cells or antibodies to react with the invading organism.
May destroy infected cells select one a cytotoxic t cells b helper t cells c b cells d allergens e phagocytic cells?
T-cells will do this
How does t cell become immunocompetent?
it doesnt
What cells become immunocompetent when the thymus secretes hormones?
The lymphocytes become immunocompetent when the thymus secretes hormones. Lymphocytes are white blood cells that are found in a vertebrate's immune system.
By secreting hormones the tymus causes what cells to become immunocompetent?
lymphocytes
When B and T cells are fully developed and mature they are described as being?
Immunocompetent
What are the two main immunocompetent cells?
b lymphocyes - plasma and memoryand t lymphcytes - cytotoxic, helper, memory and supresser
When do lymphocytes become immunocompetent?
each lymphocyte must become able (competent) to recognize its one specific antigen bye binding to it. this ability is called immunocompetence.
Which major class of lymphocytes become cytotoxic T cells?
CD8 cells become cytotoxic T cells.
What does T in T cells stand for?
The T in T-cells stands for the thymus gland. Lymphocytes produced in the bone marrow are either become B-cells or they are matured in the thymus gland and are "trained" to be either Natural Killer T-cells, CD4 (Helper T-cells), CD8 (Suppressor T-cells).
B lymphocytes develop immunocompetence in the?
Directly from my anatomy and physiology book - Marieb & Hoehn Eighth Edition: "Lymphocytes originate in red bone marrow from hematopoietic stem cells." " B cells become immunocompetent and self-tolerant in the bone marrow."
Why b cells are named so?
B-cells are matured in bone marrow. This is why they are called B-cells ("B" from bone). Similarly T-cell become mature in Thymus gland ("T" from Thymus).
What does the t cells and b cells do?
B cells stand for Bursa of Fabricus and T cells stand for T-lyphocytes.
How do helper T cells contribute to the body's defense against pathogens?
Helper T cells help to activate T-cytotoxic cells and B-cells. For instance, if you become infected with a pathogen, a macrophage can consume that pathogen and then present parts of it on its own MHC (Major Histocompatability Complex) receptors. T helper cells then detect this and if this is a pathogen previously encountered, it can stimulate T-cytotoxic cells to begin attacking infected cells, and stimulate B-memory cells to begin rapidly dividing into B-plasma cells to produce anitbodies.
