Transplant Medicine Flashcards
most important HLAs
HLA1A, HLAIb, HLA2DR
3 phases of immune response to transplant
recognition of foreign antigen
activation of antigen specific lymphocytes
effect phase of graft reject
important for activation
IL2 R (CD25) CD3 R
calcineurin
blocks transformation of t cells, which is the biggest boom step
triple therapy
calcineurin inhibitors
corticosteroids
azathiprine
calcineuron inhibiots
csa cyclosporine
mechanism of calcineurin inhib
decrease t cell proliferationa nd cytokine production by blocking calcineurin–>decativate nucler tf of t cells
side effects calcineuron inhibitors
nephrotoxicity
neurotoxicity
Mycophenolate motefil
selective antimetabolite for both t cells and b cells that works by reversibly inhibiting ionosine monophosphate–>blocks guanosine synthessis
Mycophenolate se
Bone marrow suppression
dramatic diarrhea
sirolismus (rapamycin
calcineurin inhibitor-binds to mtor and turns off cell proliferation
se- hyperlipidemia
alemtuzumab
anticd52-one dose no b or t cells for 4 hrs but last for 18 months
rituximab
anti cd 20 antibody used to decrease b cells
recipient age
older is better
donor age
older is worse
