Somatic Recombination occurs on the alpha chain of the TCR and at what stage (pro, pre, immature, mature)
Somatic Recombination occurs on the beta chain of the TCR and at what stage (pro, pre, immature, mature)
what cell is double positive (pro, pre, immature, mature)
alpha chain in the pre T
beta chain in the pro T
immature
mature cells hace what CD
CD 4 or CD 8
what binds to CTLA-4 and what does it do when it bind
CTLA-4 on the t cell binds to B7 to stop proliferation
what binds to cd28
CD28 is on T cell and it binds to B7 on the APC cell to cause proliferation
Explain the activation/ maturation of T cells
Cancer pt are given ____ to make agressive T cell
IL 2
inhibiting NFAT does what
causes immuno supression no proliferation activation of T cells —- cyclosporins
what starts proliferation of T cells … aka what binds to start proliferation
IL 2
what causes the cell to produce cyclins
IL 2 to IL2 receptors
after proliferation what two types of t cells are produced (which are shorter lived)
effector (shorter lived)
memory T (long lived)
draw types of effector Helper cells and what they secrete
what cells have FAS receptor and what cell hav FASL
all nucleated cells have FAS
CTL cd8 + bind to it
what is released if macrophage cant digest something and what does this activake
IL 12
activate NK cells
what is the first line of defense in viruses,
what does this cause
innate or adaptive
inhibition of intfection by releasing INF-a IFN-B
* antiviral mech
* increase MHC 1exp
* stimulate NK
innate
what activates NK
-INF beta and alpha
-IL12
-IL 15
sti
Central memory and effector memory difference
central
* secondary lymph tissue
* proliferate quick
Effector
* peripheral
* cecrete cytokines
* DONT PROLIFERATE
