Immune System Flashcards
what lines make up innate immunity
first and second line
effects of histamine
vascular dilation and increased capillary permeability
cell-mediated responders for adaptive immunity
cytotoxic T cells (CD8+), CD4+ (helper T’s/Th1), natural killer cells
humoral responders for adaptive immunity
CD4+ (helper T’s/Th2), B cells
APCs
dendritic cells, macrophages, and B lymphocytes
antibody responsible for long term immunity, can cross placenta, and most abundant
IgG
antibody primarily found in GI, respiratory and GU tracts
IgA
antibody that immediately responds to acute exposures
IgM
antibody responsible for allergic response and parasitic infections
IgE
clinical stages of infectious disease
incubation, prodromal, invasion, convalescence
3 kinds of convalescence
recovery, death, latency
capacity to cause disease depends on
communicability, immunogenicity (can it get immune response?), infectivity (ability to get in & multiply), mechanism of action, entry portal, pathogenicity, virulence, toxigencity
