Peritrophic Matriceshe lumenal surface to protect from food abrasion, shields from invasion by pathogenic microorganisms and regulates immune responses. It is composed of chitin fibers cross-linked by chitin-binding PM proteins (PMPs) to form a three-dimensional meshwork with water-filled pores of distinct diameters. V

Composite Eggshell Matrices: Chorionic Layers and Sub-chorionic Cuticular Envelopesrs deposited upon the developing embryo to survive biotic and abiotic stresses such as desiccation, flooding, predators and pathogens. At the same time, these protective layers must allow sperm entry and gas exchanges. During insect oogenesis most of these layers are deposited by the follicle cells:

Molecular and Structural Properties of Spider Silk00 million years, spiders have evolved to produce high performance fibers that are uniquely designed to encompass high-tensile strength and toughness. As scientists have pursued a deeper understanding of the biochemical properties of silk, investigators have discovered that spiders are capable of sp

The Complex Secretions of the Salivary Glands of ,, A Model Systemon by the steroid hormone ecdysone. The widely accepted and most well documented function of the . salivary gland is the production of a secretory glue released during pupariation to fix the freshly formed puparia to a substrate. Besides fulfilling this function, which is tightly associated with the
