T cells and cell mediated immunity

Question 1

Question: What is the primary function of T lymphocytes in the immune response?

Answer 1

Answer: T lymphocytes primarily respond to an organism’s own cells that have been invaded by non-self (foreign) material, such as viruses or cancer cells. They also respond to transplanted material that is genetically different.

Question 2

Question: What type of immune response is associated with T lymphocytes?

Answer 2

Answer: The immune response mediated by T lymphocytes is referred to as cell-mediated immunity.

Question 3

Question: What is the significance of T lymphocytes being referred to as antigen-presenting cells?

Answer 3

Answer: T lymphocytes are called antigen-presenting cells because they have the capability to present antigens from other cells on their own cell-surface membrane. This allows them to communicate with other immune cells and coordinate an appropriate response to the presence of foreign material or transplanted cells.

Question 4

Where are T-cells are produced and collected?

Answer 4

in bone marrow and collect in the thymus

Question 5

Question: What is the role of T suppressor cells in the immune response?

Answer 5

turn off the actions of the various other lymphocytes once the
pathogens have been eliminated from the body

Question 6

What are 3 types of of T lymphocytes?

Answer 6

T helper cells
T killer cells (T cytotoxic cells)
T suppressor cells

Question 7

Question: How do the structures of T cell receptors on membranes compare to antibodies, and what is their specificity?

Answer 7

like antibodies, specific to one
antigen
