Question | Answer |
---|---|
cyclosporine | calcineurin inhibitor (neoral, gengraft, sandimmune, sangcya), reduction of transcription of cytokine genes needed for Tcell activation |
tacrolimus | calcineuron inhibitor(prograft) , reduction of transcription of cytokine genes needed for Tcell activation |
mycophenolate mofetil | (cellcept)inhibition of lymphocyte proliferation, inhibits IMPDH which inteferes with purine metabolism required for lymphocyte development |
mycophneolic acid | (myfortic) inhibition of lymphocyte proliferation, inhibits IMPDH which inteferes with purine metabolism required for lymphocyte development |
Sirolimus | (Rapamycin) m-TOR inhibitors, IL2 stimulates m-TOR to activate kinase enzymes that promote cell division (G1-S phase), cytokines activate TOR |
Everolimus | (EVER) m-TOR inhibitors, Zortress for prevention of kidney rejection, Afinitor for cancer advanced- ca and tumors |
induction immunosuppression | poly/monoclonal antibody, Azathioprine, mycophenolate mofetil, glucocorticoids (methylprdeisolone/prednisone) followed by calcineuron inhibitors or tacrolimus |
ATGAM | polyclonal antibody from horses, depleting induction, T cells opsonized and then destroyed by complement system |
thymoglobin | polyclonal antibody from rabbits, depleting induction, T cells opsonized and then destroyed by complement system |
alemtuzamab | monoclonail antibody (CAMPATH-1 H), depleting induction, acts directly on CD52, given with methylprednisolone |
OKT3 | mouse monoclonial anti CD3, binds CD3 complex associated w/ TCR and triggers then blocks the TCR and inactivates or kills the T cell, short t1/2, neutralized by AB response, 1st dose cytokine release syndrome |
ALG,ATG | polyclonal horse/rabbit antilymphoctye/thymocyte globulin, contains AB against protiens on lymphocytes that alter traffic, trigger, kill and sequester the T/B lymphocytes. 1st dose cytokine releasesyndrome, thrombocytopenia, leukopenia |
basiliximab | non-depleting (simulect) binds to CD25 in IL2 receptor complex, rendering all T cells resistant to IL2, long half life once CD25 is saturated, virtually no toxicity |
Azathioprine | anti proliferative drug (inhibition of lymphocyte proliferation), anti-metabolite and immunosuppressive effects resulting in inhibition on DNA and RNA and protien synthesis to inhibit lymphocyte prolieferation |
glucocorticoids | prednisone and methylpredisolone sodium succinate, general immunosuppressive, inhibit IL1 and IL2 which decreases activation and proleiferation of T cells |
Belatacept | (Nulojix)signal 2 selective co-stimulation blocker, binds co-stimulatory B7 ligands receptors(CD80 or C86) on APC and prevents interaction with CD 28 on t cels to inhibit t cell activation |
dacilizumab | non depleting(zanapax) binds to CD25 in IL2 receptor complex, rendering all T cells resistant to IL2, long half life once CD25 is saturated, virtually no toxicity |
