Study Uncovers GPR45’s Role in Regulating Food Intake via Brain’s Primary Cilia

Quick Summary

• The melanocortin system plays a central role in regulating energy homeostasis.
• Key components of this system include the melanocortin-4 receptor (MC4R) and adenylyl cyclase 3 (ADCY3), which are located in neuronal primary cilia.
• Mutations in MC4R and ADCY3, as well as dysfunctions related to ciliary processes, are significant factors impacting energy balance.

Indian Opinion Analysis
The findings on the melanocortin system’s influence on energy homeostasis have implications for health research globally, including India. With increasing rates of metabolic disorders such as obesity and diabetes within the contry, understanding pathways like those involving MC4R and ADCY3 could pave the way for targeted genetic or pharmaceutical interventions. As India continues to face challenges related to non-communicable diseases linked to lifestyle changes and urbanization, research on neural mechanisms may offer scientifically grounded solutions to alleviate public health burdens over time.
