AI Article Synopsis
- Skin mucus serves as the primary defense barrier in fish, specifically studied in European sea bass (Dicentrarchus labrax) through protein identification using 2D electrophoresis and LC-MS/MS.
- The research highlights proteins linked to immune responses in fish, including apolipoprotein A1, calmodulin, complement C3, lysosome, and others, revealing insights into mucosal innate immunity.
- This study represents the first comprehensive analysis of skin mucus proteome and its associated gene expression, offering a non-invasive method to track immune markers that could aid in fish disease prevention and diagnosis.
Article Abstract
Skin mucus is the first barrier of fish defence. Proteins from skin mucus of European sea bass (Dicentrarchus labrax) were identified by 2DE followed by LC-MS/MS. From all the identified proteins in the proteome map, we focus on the proteins associated with several immune pathways in fish. Furthermore, the real-time PCR transcript levels in skin are shown. Proteins found include apolipoprotein A1, calmodulin, complement C3, fucose-binding lectin, lysozyme and several caspases. To our knowledge, this is the first skin mucus proteome study and further transcriptional profiling of the identified proteins done on this bony fish species. This not only contributes knowledge on the routes involved in mucosal innate immunity, but also establishes a non-invasive technique based on locating immune markers with a potential use for prevention and/or diagnosis of fish diseases.

The nutritional status of fish is essential for its health, experimental studies, and aquaculture practices. The current study investigated the impact of food deprivation on biochemical parameters, histology of skin, gill, and kidney tissues, and ultrastructure of gills in Clarias batrachus. Fish were subjected to food deprivation for 2, 7, and 15 days resulting in (a) significant increase in plasma cortisol levels, (b) no significant changes in plasma osmolality and plasma glucose content, and (c) significant decrease in liver and muscle glycogen contents.

As marine equipment advances from shallow to deep-sea environments, the demand for high-performance antifouling materials continues to increase. The lionfish, a species inhabiting both deep-sea and shallow coral reefs, prevents fouling organism adhesion via its smooth, mucus-covered skin, which contains antimicrobial peptides. Inspired by lionfish skin, this work integrates zwitterionic segments with hydration-based fouling-release properties and the furan oxime ester structure with intrinsic antibacterial activity to develop a silicone-based antifouling coating capable of operating from shallow to deep-sea environments.
