When Hyalophora cecropia hemolymph was injected into wandering Actias luna larvae, a methionine-rich hexamerin was selectively transferred to the host's fat body, and completely cleared from the hemolymph by the time of pupal eclosion. Donor arylphorin was 30-40% removed from the hemolymph, and
Insects have an effective humoral immune system, residing in immune proteins that are synthesized largely in the fatbody. kappa B-like motifs upstream of the immune protein genes bind the Cecropia immunoresponsive factor (CIF), and confer high levels of inducible expression. We have extended our
1. In the pupal stage of the cecropia silkworm, antigen 7, a protein with the solubility characteristics of an albumin, is present in female blood in approximately a thousand times higher concentration than in the blood of males. Antigen 7 is undetectable in the blood of larvae of either sex. It
