Short neuropeptide F in integrated insect physiology

Area of Science:

• Insect neuroendocrinology
• Neurobiology
• Molecular signaling

Background:

• Short neuropeptide F (sNPF) is a conserved insect neurohormone family.
• sNPF precursors contain 1-4 isoforms, and its receptor (sNPFR) is a G protein-coupled receptor.
• sNPFR is an ortholog of the mammalian prolactin-releasing peptide receptor (PrPR).

Purpose of the Study:

• To review the current knowledge of the sNPF system in insects.
• To highlight the diverse physiological roles of sNPF.
• To discuss interactions with other signaling pathways.

Main Methods:

• Literature review of studies on sNPF and its receptor in insects.
• Comparative analysis across different insect orders.
• Synthesis of findings on sNPF's physiological functions.

Main Results:

• sNPF regulates feeding, foraging behavior, olfaction, reproduction, development, locomotion, and circadian rhythms.
• sNPF effects on feeding are species-specific.
• The sNPF pathway interacts with insulin-like peptides, SIFamide, and pigment-dispersing factors.

Conclusions:

• The sNPF system is a key regulator of diverse physiological processes in insects.
• Understanding sNPF signaling provides insights into insect neurobiology and behavior.
• Further research can elucidate species-specific roles and therapeutic potential.
