“Lepidopteran insect innate cellular non-self-responses are initiated by the

interaction of plasma factors, such as lectins, lipoproteins, hemolin and host alarm molecules, and hemocyte surface receptors with microbial surface antigens [44], [79], [35], [81], [76], [4] and [5]. Plasma-independent hemocyte reactions are stimulated by microbial molecular antigens Selleck Idelalisib [33] and electrostatic charges [39] and [28], both mediated by hemocyte scavenger receptors, such as those for polyanionic lipopolysaccharides (LPS) and lipoteichoic acids (LTA) on the hemocytes of the lepidopterans Bombyx mori and Spodoptera exigua [52] and [20]. Large-scale bacterial infections of lepidopteran larvae are isolated by the non-self-hemocytic nodulation reactions. Nodule formation is a biphasic response initiated

by the release of adhesion proteins by the surveillance hemocyte type, the granular cell, trapping the microbes in coagulum and forming microaggregates with other granular cells [58]. These proto-nodules are ultimately walled off by the hemocyte type, the plasmatocyte, forming the nodule [59]. Insect hemocytes in vitro form microaggregates resembling those observed in vivo during nodulation [74]. Studies in vitro have identified extracellular Enzalutamide mouse matrix proteins, e.g. lacunin [50] and the transmembrane proteins, neuroglian [83] and tetraspanin, the latter facilitating integrin-mediated adhesion between adjacent granular cells and plasmatocytes [84]. Homotypic plasmatocyte adhesion of Pseudaletia separata is mediated by the integrin β-subunit binding to a growth blocking cytokine after tyrosine phosphorylation [51]. Cell-mediated responses of Manduca sexta α2 hemocytic integrins is impeded by RGD peptides [85] further implying integrins participate in hemocyte–hemocyte adhesion responses.
