Aquaporins are small integral membrane proteins that function as pore channels for the transport of water and other small solutes across the cell membrane. Considering the important roles of these proteins in several biological processes, including host-parasite interactions, there has been increased research on aquaporin proteins recently. The pre...

Hydrogen peroxide (H2O2) is a non-pharmacological antiparasitic used to control adult copepod ectoparasites in salmonid farming worldwide. Its functional mechanism is based on forming bubbles in the hemolymph and tissues, detaching the parasite from the host. However, to date there is no information on the molecular effects of H2O2. This study eval...

Sea lice are one of the main parasites affecting the salmon aquaculture industry, causing significant economic losses worldwide. Increased resistance to traditional chemical treatments has created the need to find alternative control methods. Therefore, the objective of this study was to identify the transcriptome response of the salmon rogercress...

Cathepsins are proteases involved in the ability of parasites to overcome and/or modulate host defenses so as to complete their own lifecycle. However, the mechanisms underlying this ability of cathepsins are still poorly understood. One excellent model for identifying and exploring the molecular functions of cathepsins is the marine ectoparasitic...

Deltamethrin is an insecticide authorized for use against the ectoparasite Caligus rogercresseyi in salmon aquaculture. The biodegradation of this insecticide is principally catalyzed through P450 enzymes, carboxylesterases, and glutathione-S-transferase, increasing the amount of free radicals that could promote the activation of oxidative stress r...

Caspases play an important role in the different stages of programmed cell death, or apoptosis, which has been related to the immune response in multicellular organisms. The present study characterized an initiator caspase (HrCas8) and an effector caspase (HrCas3) from the red abalone Haliotis rufescens using the RACE method and qPCR analysis. HrCa...
