IFN-γ secreted by Th1 cells does what important action
M1 macrophage activation
M1 macrophages secrete…
IL-1
TNF-α
Th4 T-cells secrete IL-4, IL-5, and IL-13 that activate what type of cell
M2 macrophage
Follicular cells secrete IL-4 and IL-21 that function to…
class switch B-cells
Regulatory T-cells suppress the function of which cells?
activated CD4+ T-cells Th0 cells (decreases proliferation)
Cytotoxic T-cells depend on what activation mechanism?
FAS-FAS ligand in conjunction with CD8, TCR interacting with MHC-I
T/F
Memory T-cells can redifferentiate back into cytotoxic T-cells
T
How do you get memory T-cells from CD8+ cells?
medium expression of IL-2 receptor, like an ‘eh’ kind of differentiation
Which type of cell express both MHC-I and MHC-II?
dendritic cells
CD3 on T-cells is analogous to what on B-cells?
CD79a and CD79b
T/F
Somatic hypermutation occurs in T-cells
F
T-cells are fully/terminally differentiated when they leave the thymus and don’t change after that
TCR alpha genetics
VJ + constant region
TCR beta genetics
VDJ + constant region
T/F
Somatic mutation occurs in T-cells
T
somatic mutation: adding on some nucleotides to segments
