Autophagy and white spot syndrome virus infection in crustaceans

Abstract

Autophagy is an evolutionarily conserved process of degradation in eukaryotes, which can form double-membrane vesicles for delivering the trapped cargo to lysosome for degradation, also facilitate host cells against the invasion of foreign pathogens. Recently, autophagy was reported to participate in viral infection in crustaceans. White spot syndrome virus (WSSV) is the most severely viral pathogen for farmed crustaceans, particularly in crayfish and shrimp. In this review, we summarized and discussed the current findings of autophagy involved in WSSV infection in crustaceans, particularly focusing on the identified autophagy-related molecules and their effects on viral infection. We hope this summary will provide us a better understanding of autophagy and its contribution to antiviral immunity in crustaceans.
