T cells and Cellular Immunity Flashcards
These cells combat intracellular pathogens, and cancer cells
T cells/ Cellular Immunity
T cell that assist in humoral immunity/ b cell activation
T helper cell
T cell that recognize/ destroy infected/cancer cells; can become a cytotoxic T lymphocyte; secretes cytokines
Helper T cells (CD4)
Type of T cells whose target cells are self carrying endogenous antigens(mainly viral/parasitic); killer cells that cause cell lysis
CD8/Cytotoxic Cells
T cells typically protect body against which events
Tumor surveillance/destruction
Intracellular Infection
Viral, Fungal, Parasitic Infection
Transplant rejection
signaling cells produced by CD4 T helper cells to help fight infection
Lymphokines
responsible for recognizing antigens from previous exposure; protect older population; recognize and activate immune response
Memory Cells
white blood cells that help regulate the immune system by preventing other lymphocytes from becoming overactive
suppressor T cell
