Choline dehydrogenase interacts with SQSTM1 to activate mitophagy and promote coelomocyte survival in Apostichopus japonicus following Vibrio splendidus infection.

ABSTRACT: Previous studies have shown that Vibrio splendidus infection causes mitochondrial damage in Apostichopus japonicus coelomocytes, leading to the production of excessive reactive oxygen species (ROS) and irreversible apoptotic cell death. Emerging evidence suggests that mitochondrial autophagy (mitophagy) is the most effective method for eliminating damaged mitochondria and ROS, with choline dehydrogenase (CHDH) identified as a novel mitophagy receptor that can recognize non-ubiquitin damage signals and microtubule-associated protein 1 light chain 3 (LC3) in vertebrates. However, the functional role of CHDH in invertebrates is largely unknown. In this study, we observed a significant increase in the mRNA and protein expression levels of A. japonicus CHDH (AjCHDH) in resp
