Sosnowski Acute and Chronic Inflammation Flashcards
(25 cards)
marker for selectins
CD34
2 different types of leukocyte adhesion molecules
selectins and integrins
type of integrin that pulls neutrophil through endothelium
PECAM-1
this receptor along with death toll-like receptor bind to sugar on microbe and bring it into cell and kill it
CD14
this receptor binds to sugar on microbe and bring it into cell and kills it
mannose receptor
process of how a microbe gets degraded: 4 basic steps
microbe attaches to receptor
endocytosis into cell
phagosome and lysosome combine
destruction of microbe
best killing component in cells; secretes H2O2
MPO (myeloperoxidase)
presents with candida albicans infections; caused by enzyme deficiency and environment
MPO deficiency
important in the ability of immune system to clear microbes
C3 (and its cleavage)
deals with inflammation (chemokines); leukocytes to destroy microbes
C3a
deals with phagocytosis through opsinin coat
C3b
forms MAC (membrane attack complex) and causes lysis of microbe
C3b
serous (deals with plasma) inflammation example
blister
purulent inflammation example
acne
acute inflammation can lead to what 2 things
chronic and then fibrosis inflammation
this syndrome results from impaired adhesion and migration of leukocyte through endothelium
Polymorphonuclear leukocyte dysfunction syndrome
2 main things chronic inflammation causes
atherosclerosis
arthritis
marker for macrophages
CD68
marker for langerhan’s cells (presents microbe to lymph node)
CD1
disease that arises from macrophages not being able to get rid of microbe; so they recruit leukocytes(lymphocytes)
chronic granulomatous disease
large sphere where macrophages are on the inside and lymphocytes (a type of leukocytes) are on the outside
granuloma
deals with antigens and process for anaphylaxis
Type I hypersensitivity disease
deals with antibodies; binds to neuromuscular junction
Type II hypersensitivity disease
deals with antigen-antibody complexes
Type III hypersensitivity disease
