TL;DR: It is now clear that the innate immune system is very important for self or non-self recognition in vertebrates and that it provides instruction that enable the adaptive immune response to enhance immunogenicity.

The proPO and clotting system in crustaceans
TL;DR: This paper reviews what is known so far about crustacean defence mechanisms, particularly of penaeid shrimp, with special emphasis on the proPO and the clotting system.
Journal ArticleDOI
Prophenoloxidase system and its role in shrimp immune responses against major pathogens.
TL;DR: This review highlights the recent discoveries of the critical roles of the proPO system in the shrimp immune responses against major pathogens, and emphasizes the functional characterizations of four major groups of genes and proteins in the pro PO cascade in penaeid shrimp, that is the PRPs, serine proteinases, proPO and inhibitors.

Gram-negative Bacteria-binding Protein, a Pattern Recognition Receptor for Lipopolysaccharide and β-1,3-Glucan That Mediates the Signaling for the Induction of Innate Immune Genes in Drosophila melanogaster Cells

TL;DR: The results suggest that DGNBP-1 functions as a pattern recognition receptor for LPS from Gram-negative bacteria and β-1,3-glucan from fungi and plays an important role in non-self recognition and the subsequent immune signal transmission for the induction of antimicrobial peptide genes in the Drosophilainnate immune system.

Single-step method of RNA isolation by acid guanidinium thiocyanate-phenol-chloroform extraction
TL;DR: A new method of total RNA isolation by a single extraction with an acid guanidinium thiocyanate-phenol-chloroform mixture is described, providing a pure preparation of undegraded RNA in high yield and can be completed within 4 h.

Cellular immunity in crustaceans and the proPO system.
TL;DR: The function of the proPO system in cellular immune reactions in crustaceans and in particular the role of a protein with a molecular mass of 76 kDa, which has been shown to be involved in the communication between the different blood cell types of crayfish, are discussed.

Soluble chromogenic substrates for the assay of endo-1,4-beta-xylanases and endo-1,4-beta-glucanases
TL;DR: New soluble chromogenic substrates were prepared for specific and rapid assays of endo-1,4-beta-xylanases and endo -1, 4- beta-glucanases, advantageous for rapid analyses of large amount of samples and also permit evaluation of the activities of both enzymes in the presence of exo-Beta-glycanases and beta-glycosidases.
