Abstract

The distribution of integument peptides in relation to chitin and structural features has been studied in the surface epidermis of the caterpillar of Calpodes ethlius by immunoblotting and immunogold labelling using antibodies prepared to peptides isolated from lamellate endocuticle or from hemolymph. The intermoult cuticle consists of an epicuticle, an endocuticle of many chitin containing lamellae, and a chitin containing assembly zone directly above the apical epidermal microvilli and the perimicrovillar space. During the intermoult, the epidermis secretes peptides constitutively, that is, secretory vesicles containing peptides exocytose without accumulating, traverse the perimicrovillar space and form lamellae in the assembly zone. At moulting, the epidermis deposits ecdysial droplets in addition. These interrupt the last few lamellae which later go on to become the perforated ecdysial membrane. The integument is involved with four routing classes of peptide. Secretion is apical into the cuticle (C), basal into the hemolymph (H), bidirectional (BD), or transported to the cuticle across the epidermis from the hemolymph (T). Some peptides change their routing at moulting. There are several patterns of localization. (1) C and ...Continue Reading

Antibody Specificity

Antibodies produced by B cells are highly specific for antigen as a result of random gene recombination and somatic hypermutation and affinity maturation. As the main effector of the humoral immune system, antibodies can neutralize foreign cells. Find the latest research on antibody specificity here.
