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.
Journal ArticleDOI
Shrimp humoral responses against pathogens: antimicrobial peptides and melanization.

TL;DR: Interestingly, the pattern recognition protein (PRP) crosstalk is evidenced between the proPO activating cascade and the AMP synthesis pathways in shrimp, which enables the innate immune system to build up efficient immune responses.
Journal ArticleDOI
Molecular cloning, genomic organization and recombinant expression of a crustin-like antimicrobial peptide from black tiger shrimp Penaeus monodon
TL;DR: A novel crustin-like antimicrobial peptide (Crus-likePm) was identified from haemocytes of Penaeus monodon and showed strong antimicrobial activity against both Gram-positive and Gram-negative bacteria including V. harveyi, a major pathogenic bacteria in shrimp aquaculture.
Journal ArticleDOI
Cationic Antimicrobial Peptides in Penaeid Shrimp
Anchalee Tassanakajon,Piti Amparyup,Piti Amparyup,Kunlaya Somboonwiwat,Premruethai Supungul,Premruethai Supungul +5 more
TL;DR: The information available on antimicrobial activities of cationic AMPs in penaeid shrimps indicates that these shrimp AMPs have potential therapeutic applications in the control of disease problems in aquaculture.
Journal ArticleDOI
Two prophenoloxidases are important for the survival of Vibrio harveyi challenged shrimp Penaeus monodon.
TL;DR: A novel proPO gene (PmproPO2) belonging to the proPO family identified from the P. monodon EST database is reported, suggesting that the two proPOs are important components in the shrimp immune defense.
