Adaptive immune Can be acquired
response either naturally or
artificially Both
types are specific
and have memory
Natural adaptive an organism or toxin enters the body and
immunity promotes an immune response
Artificial adaptive results from immunization with a vaccine
immunity
- Immune response protects against one
pathogen
Specific - Does not protect against other
pathogens
- Only exception is when two
pathogens are very closely related.
ex. Smallpox and Cowpox

Memory - Result in a much stronger response upon
re-exposure
- Long term immunity - possibly for life.
Adaptive immunity Exogenou
Involves two s antigens
general responses Endogeno
that respond us
against antigens antigens
antigens Molecules that interact specifically
with the adaptive immune system
and elicit an adaptive response.
Exogenous Come from outside• Ex. Bacteria, viruses,
antigens toxins
Endogenous Generated inside a body cell.
antigens
Antibody mediated - Detect exogenous antigens and
response - proliferate to form plasma cells
(Humoral - Produce small protective molecules -
response) - B cells antibodies(Ab)
- Bind to the surface of bacteria, viruses,
toxins, etc.
Cell mediated Helper T cells (TH) and Cytotoxic T cells
response (TC)
Direct and assist adaptive immunity and
upregulate innate immunity

- Deliver cytokines to activate
Helper T cells (TH) naive B cell -> proliferation to
plasma cells -> antibodies.
- Deliver cytokines increasing macrophage
killing power.
