I. Characterization of the adjuvant effect. PG - 363-6 AB - The adjuvant activity of 5 different lysolecithin analogs (LLA) has been studied in delayed-type hypersensitivity (DTH) using fowl gamma globulin, bovine serum albumin and the terpolymer L-glutamic acid 60-L-alanine30-L-tyrosine10(GAT), as antigens. Increased DTH responses, by factors of 1.8--2.0 in CBA and BALB/c mice, showed that LLA are immunopotentiators if given intraperitoneally (i.p.) or subcutaneously (s.c.) together with the antigen. The concentration range, within which LLA are active, is limited to 10--20 micrograms/mouse s.c. and 100--300 micrograms/mouse i.p. Adjuvanticity was tested as a function of the LLA structure. The most pronounced immunopotentiation was obtained with racemic 1-octadecyl-2-methylglycero-3-phosphorylcholine (ET18-O-CH3). The LLA became less active with decreasing numbers of C atoms in the alkyl chain.
