The primary components of the innate immune system

include physical barriers like skin and mucous

membranes, phagocytic cells such as macrophages and

neutrophils, natural killer cells, the complement system,

and various cytokines.

How do T cells recognize

antigens?

T cells recognize antigens through their T cell receptors

(TCRs), which bind to peptide antigens presented on

major histocompatibility complex (MHC) molecules on

the surface of antigen-presenting cells.

What is the difference

between humoral and cell-

mediated immunity?

Humoral immunity is mediated by B cells and involves

the production of antibodies to neutralize pathogens,

whereas cell-mediated immunity involves T cells that

directly kill infected cells or help other immune cells.

Explain the role of cytokines

in the immune response.

Cytokines are signaling proteins secreted by immune

cells that regulate the intensity and duration of immune

responses by promoting cell activation, differentiation,

proliferation, and communication between cells.
