How does adaptive immunity differ from innate immunity?
it has a specific response to antigen
adaptive immunity
body’s ability to recognize and defend itself against invaders
ability to differentiate between self and non self
MHC-1
major histocompatibility complex
memory
has a more effective response to pathogens and is faster
dendritic cells
are the strongest antigen presenting cells
epitopes
the 3D region of the antigen that leads to immune response
What are the three types of antigens?
exogenous, endogenous, autoantigens
lymphocytes
white blood cell that acts against specific pathogens
forms in red bone marrow
What are the two types of lymphocytes?
B and T
T cells
derived from the thymus
TH and CTL
TH
t helper cell which can go to B cell only, T cell only, or both
regulates activity of B and T cells
What is the fastest response?
booster response
CTL
cytotoxic lymphocyte that sends a signal to a cell to perform apoptosis
perforins
fired by CTL to poke holes
regulatory T lymphocyte
represses adaptive immune response
