T-helper cells release hormone-like substances called?
the t-cells release hormone-like substance called
B cells interacting with helper T cells are stimulated to differentiate when?
Helper t cells release cytokines
How do cells involved in the humoral response respond to antigen presentation on the surface of a B cell?
Helper T cells recognize the receptor-antigen complex and cause plasma and memory cells to be produced to then produce antibodies.
How do killer cells work?
Killer t cells are activated by helper t cells. The Helper t cells are alerted by the macrophage that has engulfed the virus. It grows antigens to alert the helper t cells. The killer t cells are like white blood cells, there purpose is to fight pathogens.
What are the testes use?
Testes produce sperm cells in male animals in addition to hormones and other useful chemicals.
Lymphocytes that act directly on antigens to destroy them or produce chemicals that are toxic to them called?
Lymphocytes that act directly on antigens to destroy them or produce chemicals that are toxic to them are called T4 cells. They are also known as T helper cells.
Which chemicals are secreted by T-helper cells to stimulate b-plasma cells to divide?
These chemicals are called CYTOKINES.
What chemicals do white blood cells produce?
white blood cells can make chemicals called antitoxins that destroy the toxins produced by bacterica.
Which immune cells are attracted to the chemicals secreted by helper T cells?
Cytotoxic t cells and b lymphocytes!
What immune system cells are attracted to the chemicals secreted by helper T cells?
Cytotoxic t cells and b lymphocytes!
Which describes T cells?
They produce chemicals to fight infection and later produce chemicals to "turn off" the immune system.
Does Cardbon Dioxde produce cells?
No, Because chemicals are not living things...only living things will produce cells.
What are Helper T cells?
Helper T cells are a type of white blood cell that play a crucial role in the immune response by coordinating and regulating the activities of other immune cells. They help activate B cells to produce antibodies and assist cytotoxic T cells in killing infected cells. Helper T cells are essential for a properly functioning immune system.
T-helper cells release hormone-like substances called?
the t-cells release hormone-like substance called
B cells interacting with helper T cells are stimulated to differentiate when?
Helper t cells release cytokines
What are parts of the immune system and functions?
Helper T cells are required to activate both the B cells that produce antibodies, and the T cytotoxic cells that attack and destroy pathogenic cells
How is HIV and Helper T Cells related?
T helper cells, also called CD4+ T cells (or just CD4 cells) are part of the immune system, but they are also the main target cells that HIV infects and uses to reproduce.
