Cover Story: When it comes to predation, alarm signals enable organisms to assess risk and modulate their behavior accordingly. These signals are typically released through injury-induced mechanisms in response to predation. While extensively documented in teleosts, such mechanisms remain poorly understood in more basal vertebrates, such as lampreys. The present study investigated the potential role of skein cells in the immune and alarm signaling systems of the sea lamprey (Petromyzon marinus). These cells may be involved in mucus secretion and the release of defense compounds. This study employed histomorphological analysis, immunoperoxidase labeling, confocal microscopy, bioinformatics, and quantitative and statistical analyses to test the hypothesis that skein cells contribute to anti-predator defense via the release of alarm substances. View this paper
