Peptides studied for sleep architecture and circadian regulation.
Sleep- and circadian-active peptides are studied for their role in regulating sleep architecture, the timing of the biological clock, and the pineal signaling that links light exposure to rest cycles.
Research interest centers on how these peptides influence slow-wave sleep, melatonin-adjacent pathways, and the interaction between the sleep system and the stress axis. The field overlaps substantially with aging biology, where circadian decline is a recurring theme.
