Physiological Roles and Functions

Bombesin-like peptides are implicated in a wide array of physiological functions.Characterization and distribution of bombesin-like peptides ... One of their well-documented roles is the regulation of food intake; they can inhibit appetite when administered peripherally or centrally, acting on satiety mechanisms. Beyond appetite control, these peptides are involved in mediating stress responses, influencing normal lung development, and modulating inflammation. Their actions are often mediated through specific receptors, such as the BB1 and BB2 receptors, which are part of the mammalian bombesin receptor system. This system is crucial for regulating energy homeostasis, making it a potential target for pharmacological interventions related to metabolic disorders.Bombesin-like peptides inhibit food intakewhen injected either peripherally or centrally by acting on satiety.
