Article Synopsis
- The thioredoxin (TRX) system in crustaceans serves as an antioxidant and plays a role in the immune response during viral and bacterial infections by managing reactive oxygen species.
- Recent increases in marine viruses have negatively impacted shrimp aquaculture, highlighting the need to understand how shrimp like Litopenaeus vannamei respond to these infections.
- The study showed that TRX gene expression was significantly altered in response to the white spot syndrome virus (WSSV), with a stronger reaction compared to the infectious hypodermal and hematopoietic necrosis virus (IHHNV), indicating that different viruses can trigger varied responses in shrimp TRX levels.

Cathepsin B is a cystein proteinase scarcely studied in crustaceans. Its function has not been clearly described in shrimp species belonging to the sub-order Dendrobranchiata, which includes the white shrimp Litopenaeus vannamei and other species from the Penaeidae family. Studies on vertebrates suggest that these lysosomal enzymes intracellularly hydrolize protein, as other cystein proteinases.
