Pattern recognition proteins in Manduca sexta plasma

Insect Biochemistry and Molecular Biology, 2002
Recognition of nonself is the first step in mounting immune responses. In the innate immune systems of both vertebrates and arthropods, such recognition, termed pattern recognition, is mediated by a group of proteins, known as pattern recognition proteins or receptors.

Studies on lipid transport in Manduca sexta (Insecta)

Comparative Biochemistry and Physiology, 1970
Abstract In vitro studies with the adult fat body of the tobacco hornworm, Manduca sexta, indicate that when the moth ingests glucose, the sugar is converted to lipid which is released from the fat body into the haemolymph as diglyceride.

Hematopoietic organs of Manduca sexta and hemocyte lineages

Development Genes and Evolution, 2003
Cells of the moth immune system are derived from organs that loosely envelop the four wing imaginal discs. The immune response in these insects is believed to depend on the activities of two main classes of hemocytes: plasmatocytes and granular cells.

Associative olfactory learning in the moth Manduca sexta

Journal of Experimental Biology, 2000
The proboscis extension response conditioning protocol has been used to explore olfactory-based associative learning in an array of insects. We have monitored a different feeding reflex, which involves activation of the cibarial pump, to demonstrate olfactory learning in the moth Manduca sexta.

Regulation of serpin gene-1 in Manduca sexta

Insect Biochemistry and Molecular Biology, 1995
Hemolymph of Manduca sexta contains proteins from the serpin superfamily, which are inhibitors of serine proteinases. We have used probes specific for M. sexta serpin gene-1 mRNA and protein to study the expression and hormonal regulation of this gene.

Effects of Manduca Diuresin on Neonates of the Tobacco Hornworm, Manduca sexta

General and Comparative Endocrinology, 2000
Manduca diuresin (MD), a 30 amino acid peptide, was isolated and identified from the type IIb median neurosecretory cells in the brain of adult Manduca sexta (Blackburn et al., Biochem. Biophys. Res. Commun., 181, 927-932, 1991). The synthetic hormone stimulates water loss in the adult moth both in vitro using isolated Malphigian tubule preparations ...

Hemolymph Proteinases in Immune Responses of Manduca sexta

2001
Extracellular signal transduction pathways in blood are often composed of cascades of serine proteinases to amplify rapidly a response to wounding or infection. The vertebrate blood coagulation and complement pathways are the most fully characterized of such proteinase cascades.

Debraining and diapause development in Manduca sexta pupae

Journal of Insect Physiology, 1974
Debraining experiments with wounded and normal controls were done at three different ages on diapausing Manduca sexta pupae of Kentucky and Illinois stocks. With early ages of both stocks debrained pupae escaped from diapause over an extended period of time, but wounded insects developed much earlier and at the same time as the normals. With later ages

Developmental expression ofManduca sexta hemolin

Archives of Insect Biochemistry and Physiology, 1999
Hemolin is hemolymph protein that is a member of the immunoglobulin superfamily. Its induced expression after bacterial infection suggests that it functions in the immune response. In this paper, we describe the expression of the Manduca sexta hemolin gene at certain developmental stages in the absence of microbial challenge.
