Lecture 21&22 cell vocab - Health Science

Cytotoxic T-lymphocytes (killer T cells) (innate)

Kills cells infected by pathogen & cancer cells

Helper T cells (innate)

Activate other immune cells to do work

Type 1 Helper T Cells (innate)

Activate macrophages and natural killer cells to destroy intracellular pathogens

Type 2 Helper T Cells (innate)

Activate eosinophils and stimulate B cells; enhance responses to worms & allergens

Type 17 Helper T Cells (innate)

Stimulate inflammatory response; respond to fungi & bacteria

T regulatory cells (innate)

Inhibit functions of other T cells, dendritic cells, and B cells

Plasma cells (adaptive)

Mature B cells that produce huge amounts of many different types of antibodies

Antibody (adaptive)

Y-shaped proteins that specifically target & stick to foreign cells causing immune responses

Memory cells (adaptive)

Retain copy of B cell receptor for future use

Neutralization

Can make malaria parasite toxins less harmful

Opsonization

Can make innate cells more likely to phagocytize

Complement activation

Can “turn on” other innate immune systems to attack malaria parasite
