    This book contains the proceedings of the first meeting on invertebrate immunity ever sponsored as a summer research conference by the Federation of American Societies for Experimental Biology .   A lipopolysaccharide-specific lectin, immulectin-2, was isolated from plasma of the tobacco hornworm,Manduca sexta. Immulectin-2 has specificity for xylose, glucose, lipopolysaccharide, and mannan. A cDNA clone encoding immulectin-2 was isolated from an Escherichia coli-inducedM. sexta .

    Characterization of a novel Manduca sexta beta-1, 3-glucan recognition protein (βGRP3) with multiple functions. Insect Biochemistry and Molecular Biology , 52, DOI: . The tobacco hornworm Manduca sexta is widely used as a model organism to investigate the biochemical basis of insect physiological processes but little transcriptome information is available.

    Molecular Mechanisms of Immune Responses in Insects covers various aspects of these mechanisms starting with a historical chapter on the origins of insect immunity. There are also chapters that cover antibacterial peptides from insects and their mode of action, relationships between insect defense proteins and development and immune 5/5(1). Polydnaviruses (PDVs) are endogenous particles that are used by some endoparasitic hymenoptera to disrupt host immunity and development. Recent analyses of encapsidated PDV genes have increased the number of known PDV gene families, which are often closely related to insect genes. Several PDV proteins Cited by:

Scolexin is a coagulation-provoking plasma protein induced in response to bacterial or viral infection of larval Manduca sexta, a large lepidopterous insect. Here we report the isolation and sequencing of two cDNA clones that code for scolexin isoforms sharing 80% sequence identity.

The scolexin Scolexin immune protein from Manduca sexta book have low but recognizable sequence similarity to members of the chymotrypsin family and represent a new subfamily of chymotrypsin-like serine by: Scolexin is a coagulation‐provoking plasma protein induced in response to bacterial or viral infection of larval Manduca sexta, a large lepidopterous insect.

Here we report the isolation and sequencing of two cDNA clones that code for scolexin isoforms. The Manduca sexta larva-specific immune protein, scolexin, was isolated and 14 CH 3-labelled by reductive alkylation. The influence of the bacterium Streptococcus faecalis on the hemocoelic distribution of the labelled scolexin was then analyzed.

During bacterial challenge, most of the scolexin signal was detected in association with the hemocyte aggregations and nodules which formed; in this respect the protein Cited by: 4.
