TI Induction of a CD8+ cytotoxic T lymphocyte response to soluble antigen
given together with a novel muramyl dipeptide adjuvant,
N-acetyl-D-glucosaminyl-(beta
1-4)-N-acetylmuramyl-L-alanyl-D-isoglutamine (GMDP).

AB We have investigated the ability of the novel muramyl dipeptide, GMDP,
to act as an adjuvant for the induction of ovalbumin (OVA)-specific,
CD8+ cytotoxic T lymphocyte (CTL) responses. C57Bl/6 mice were twice
immunized s.c. with 50 micrograms OVA emulsified with a squalane, L121
pluronic containing Tween-80 vehicle either with (STP-GMDP) or without
(STP) GMDP. Splenic precursor CD8+ CTL activity against E.G7-OVA, but
not against EL-4 parental targets was detected in STP-GMDP immunized
mice after 5 days of in vitro re-stimulation with irradiated E.G7-OVA
cells, while mice immunized with OVA in STP alone or OVA alone failed to
demonstrate CTL activity. OVA emulsified in a microfluidized STP vehicle
formulation without GMDP also elicited the E.G7-OVA precursor CTL. The
ability of GMDP to induce a class I-restricted, CD8+ CTL response to a
soluble protein antigen may have implications for the development of
useful vaccines against viral pathogens or tumours against which CTL
responses are desirable.
