Elements of Immune System Flashcards
response time of innate immunity?
minutes to hours aka fast
major components of innate immunity?
- physical and chemical barriers
- serum complement
- phagocytes
how good is innate immunity at detecting microbes?
it only sees conserved characteristics of microbes (pattern recognition receptors PRR) so it is limited
how is the specificity of response of innate immunity?
specificity is fixed aka cannot adjust or adapt
because goal is to have a quick response to control growth
what are the effector mechanisms of innate immunity
- complement activation (lysis)
2. phagocytosis
what is the innate immune response to repeat infection?
the same duration and amount of response each time
response time of adaptive immunity
days
major components of adaptive immunity
- T cells
2. B cells
how good is adaptive immunity at detecting microbes?
responds to any antigen (diverse) and has numerous BCR and TCR
effector mechanisms of adaptive immunity?
- cytokines for apoptosis and inflammation
- cytotoxicity (cell mediated)
- antibodies (neutralization, phagocytosis, cytotoxicity)
what is adaptive immune response to repeat infection
memory cells make more rapid and effective response with each exposure
