MISC Flashcards
What % children are food insecure?
20%
Competing brain parts in dealing with stress? Maturity age?
PFC- cognition/judgment (maturity at 24 yrs)
Amygdala- emotional/impulsive (maturity at 18yrs)
Alloantigen
antigen that body reacts to from same species
ex. HLA
Septic shock?
Blood infection from cytokines
LPS binds TLR of MAC in liver/spleen –> TNF-a release —> platelet activating factor form endothelium –> widespread clotting
Hematopoietic stem cell differentiates into? (3)
- lymphoid progenitor (–> T/B/NK cells)
- myeloid progenitor (–> granulocytes and monocytes)
- erythroid megakaryocyte progenitor (–> platelets and RBC)
B cell activation signals?
- MHC-II/antigen (B cell) - Th2
- CD40L (Th2) - CD40 (B cell)
- IL-4 binds IL-4 receptor of B cell
Describe affinity maturation
During B cell differentiation
follicular DC present antigen to B cells; only those with highest affinity will survive
Where is neutrophil recruited from during infection?
Bone marrow
What receptor does IL-8 bind? what cell?
CXCR1/2 on neutrophil
