We describe here the genetic control of humoral responses to filarial nematode Ag elicited by live adult Brugia malayi parasites in mice. Inbred and congenic mice of two different MHC haplotypes, H-2k and H-2d, were examined. Serologic analysis showed that the humoral responses to the major surface 29-kDa glycoprotein of adult parasites and a 40-kDa Ag from the surface of the microfilarial stage were restricted to mice with H-2k alleles (B10.BR, CBA/Ca, and CBA/N), whereas mice of the H-2d haplotype (B10.D2/n and BALB/c) were nonresponsive to these Ag. Conversely, internal adult Ag of molecular mass of 24 and 66 kDa were recognized only by animals with the H-2d haplotype. Apart from MHC-restricted recognition, the level of responses to phosphorylcholine and to a 15-kDa adult surface molecule were found to be influenced by non-MHC genes. A sharp restriction was also observed to an adult surface Ag complex of 17 to 200 kDa, which was recognized only by BALB/c mice. Thus, multiple examples of both H-2 and background genetic effects on the immune response to distinct filarial Ag can be found. |
