IMMUNOSUPPRESSIVE AGENTS
SPECIFIC
IMMUNOSUPPRESSIVE AGENTS
•Suppression of T-cell activity by monoclonal antibodies
•Blocking co stimulatory signals
GRAFT VS HOST DISEASE
(GVDH)
Acute GVD occurs within 8-10
days, Chronic GVD can take
upto 3 months
Agents that suppress
cytokine production is
effective in treating GVD
Immunologically privileged sites
•Tolerate graft without rejection response
–Lack or dearth of blood/Lymphatic vessels
(cornea)
•Eg
–Brain
–Anterior chamber of eye
–Uterus
–Testes
Experimental approaches to
Tissue typing
•Mixed leukocyte reaction
–One way
–Two way
•HLA Typing
Mixed Leucocyte reactions
(MLR)
•MHC Molecule rec.
by Tc cells
•Tc cells need
–MHC –peptide
–Costim. signal
