Immune Cells Vocab

Macrophage

Special immune cell that eats pathogens, displays antigens, and secretes interleukin-1, which stimulates helper T cells

B-Cells

Immune cell that secrete interferons that stimulate T cell growth, process and present antigens to helper T cells, matures in the bones.

Dendritic Cell

Immune cell that processes and present antigens to both T and B cells

Cytotoxic T cell

 Immune cell that kills host cells by releasing granzymes that induce apoptosis

Apoptosis 

Programmed cell death

Lymphotoxins

Member of the tumor necrosis factor (TNF) superfamily of cytokines that destroys target DNA

Perfoirn

Channels that cause cytolysis (cell dissolution)

Cytolysis

The dissolution or disruption of cells, especially by an external agent.

Helper T cell

 Immune cell that cooperates with B-cells to amplify antibody production,  stimulates T and B cells

Plasma Cell

Special B cell that makes antibodies

Memory T cells

T cells that remains in lymphatic tissue and recognizes an antigen even years after first encounter

Memory B cells 

B cells that remains after immune response and is ready to respond rapidly if an antigen reenters

Neutralizing Antibody

Binding of an antibody with an antigen that blocks activity or attachment.

Immobilizing bacteria

Antibody that binds against antigens on the cilia or flagella of motile bacteria, causing the pathogen to no longer be able to move.

Agglutination

Antibodies bind to numerous antigens at the same time, causing them to clump together.

Phagocytosis

The ingestion of bacteria or other material by phagocytes (eating cells)
