Hemolin is the most abundant bacteria-induced proteins in Hyalophora cecropia hemolymph. Its structural features, both at the protein and gene level, ascribe this molecule to the immunoglobulin gene superfamily (IgSF) with particular homology to neural cell adhesion molecules. An increasing number of evidence suggest a role in immune recognition and in cell adhesion events. Hemolin is also developmentally regulated as suggested by changes in its concentration during larval and pupal ecdysis (Trenczek, T., 1998. Endogenous defense mechanisms of insects. Zoology 101, 298-315; Lanz-Mendoza, H., Faye, I., 1999. Physiological aspects of the immunoglobulin superfamily in invertebrates. Dev. Comp. Immunol. 23, 359-374). In the present study the expression of hemolin was investigated in oogenesis and in early embryogenesis. Our results reveal that hemolin is expressed in follicles and in epidermal and neural tissues of embryos.
