摘要： Integrins (ITGs) are transmembrane heterodimer receptors with ITG & alpha; subunit and ITG & beta; subunit, participating in various physiological processes, including immunity. At present, systematic research on ITGs in teleost is scarce, especially in half-smooth tongue sole (Cynoglossus semilaevis). In this study, a set of 28 ITG genes in half-smooth tongue sole have been identified and characterized. The phylogenetic analysis showed that ITG & alpha; and ITG & beta; subunits were respectively classified into five and two clusters, consistent with previous studies. The selection pressure analysis indicated that most of ITG genes were under purifying selection, except for ITG & alpha;11b and ITG & alpha;L with positive selection. The expression profiles of eight selected ITG genes, including ITG & alpha;1, ITG & alpha;5, ITG & alpha;8, ITG & alpha;11, ITG & beta;1, ITG & beta;2, ITG & beta;3, and ITG & beta;8, were analyzed in healthy tissues and after infection with Vibrio anguillarum, revealed their implications in immune response. The study provided a comprehensive characterization and expression analysis of ITG genes in half-smooth tongue sole, setting a solid foundation for further functional studies and promising potential in disease control.
