Functions of T Lymphocytes definitions Flashcards

Target infected host cells presenting intracellular pathogens on MHC class I, inducing apoptosis to eliminate the pathogen.

Molecules on host cells presenting intracellular antigens, allowing cytotoxic T cells to distinguish infected from healthy cells.

A controlled process of cell death induced by cytotoxic T cells to eliminate infected cells without harming nearby healthy cells.

Enzymes released by cytotoxic T cells that degrade proteins within infected cells, aiding in apoptosis.

Molecules released by cytotoxic T cells that create pores in infected cells, allowing entry of proteases.

Differentiate into subtypes to produce cytokines, modulating immune responses and activating other immune cells.

Activate macrophages and cytotoxic T cells to respond to intracellular pathogens like viruses.

Recruit eosinophils and basophils to target multicellular pathogens such as helminths.

Activate neutrophils to combat extracellular pathogens like bacteria.

Immune cells that engulf and degrade pathogens, presenting antigens on MHC class II molecules.

Molecules on antigen-presenting cells like macrophages, presenting antigens to helper T cells.

Communication signals produced by T cells to stimulate and activate other immune cells.

Antigen-presenting cells that provide signals for naive helper T cells to differentiate into subtypes.

White blood cells recruited by TH2 cells to target multicellular pathogens.

White blood cells activated by TH17 cells to target extracellular pathogens.
