T-cells
(helper, killer, suppressor)
Macrophages
(antigen-presenting cells)
Memory Cells
( circulates to remember)
What are the functions of Cell-mediated Immunity?
Recognition of self from non-self
Surveillance system
Target Cells
Response regulated by cytokines.
What are the functions of the Helper T-Cells?
"help" the antigen-driven maturation of B and T cells
Facilitate and magnify the interactions between Antigen Presenting Cells (APC's) and immunocompetent lymphocytes.
recognizes self cells and non-self cells.
secretes lymphokines that increase bone marrow production of stem cells and speed up T-cell maturation.
NK Cells:
Natural Killer Cells
:
have cytotoxic effects n non self cells without first being sensitized.
