Rfrp [Neurons](/entities/neurons) (Rfamide Related Peptide) plays an important role in the study of neurodegenerative diseases. This page provides comprehensive information about this topic, including its mechanisms, significance in disease processes, and therapeutic implications.
Introduction
Rfrp Neurons (Rfamide Related Peptide) is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes. [@kim2022]
RFRP neurons are a population of hypothalamic neuroendocrine cells that produce RFamide-related peptides (RFRP-1 and RFRP-3). These neurons play important roles in stress response, reproductive function, metabolism, and pain modulation—all processes relevant to neurodegenerative diseases. [@patel2024]
Location
RFRP neurons are primarily located in the:
Dorsomedial hypothalamus (DMH)
Paraventricular nucleus (PVN)
Perifornical area
Marker Genes
RFRP: Rfamide related peptide (NPFF1, NPFF2 receptor expression)
