TLDR
A lower antib bacterial activity was detected in samples treated with LPS after clotting (HLF), than in those treated before clotting, suggesting that LPS was involved in mechanisms for both clotting and for antibacterial activity.About:

Immune gene discovery by expressed sequence tag analysis of hemocytes and hepatopancreas in the Pacific White Shrimp, Litopenaeus vannamei, and the Atlantic White Shrimp, L. setiferus.

TL;DR: Analysis of cDNA libraries indicates that EST approaches are effective for immune gene discovery in shrimp and that the diversity of these PCR-generated libraries would support full-scale EST collection.
Journal ArticleDOI
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
Immunostimulation in crustaceans: does it really protect against infection?
TL;DR: The problem of disease and its control in crustacean farming is considered, describing the types of capability in cultured species and the case for rigorous testing of putative stimulants is made, as well as for the need to consider alternative strategies and approaches to disease control.

TL;DR: This review highlights β-glucan as an immunostimulant, its effective dosages, and route of administration and furthermore provides an outline on role of β- glucan in enhancing growth, survival, and protection against infectious pathogens pertaining to fishes and shellfishes.
Journal ArticleDOI
Beta-glucans as conductors of immune symphonies.
Roy A. Dalmo,Jarl Bøgwald +1 more
TL;DR: This review will mainly focus on binding characteristics of beta-glucans, their effects on T helper cell differentiation, effects on functional levels, gene expression profiles and application of the commonly used ss- glucan in the aquaculture sector.

Journal ArticleDOI
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.

Lipopolysaccharide-induced activation of prophenoloxidase activating system in crayfish haemocyte lysate
Kenneth Söderhäll,Lena Häll +1 more
TL;DR: It is suggested that the prophenoloxidase activating system is an important recognition system in invertebrates and has interesting similarities with the complement system of vertebrates.

Activation of serum prophenoloxidase in arthropod immunity. The specificity of cell wall glucan activation and activation by purified fungal glycoproteins of crayfish phenoloxidase.
Kenneth Söderhäll,Torgny Unestam +1 more
TL;DR: This study shows that the activation of crayfish serum prophenoloxidase by carbohydrates was specific for beta-1,3-glucans, and that high molecular weight glycoproteins were effective.
Journal ArticleDOI
Response of penaeid shrimp to exposure to Vibrio species
TL;DR: Greater than 99% of Vibrio alginolyticus were cleared from the haemolymph of Penaeus monodon within 4 h of exposure to the heat-killed bacteria.
Journal ArticleDOI
Exocytosis of the prophenoloxidase activating system from crayfish haemocytes
TL;DR: It is concluded that, in arthropods, LPS serve as a indicator of Gram negative bacteria and β-1,3-glucan as an indicator of fungi.
