mTORC1 and CB1 receptor signaling regulate excitatory glutamatergic inputs onto the hypothalamic paraventricular nucleus in response to energy availability

Molecular Metabolism, 2019
Objective: The hypothalamic paraventricular nucleus (PVN) is a key target of the melanocortin system, which orchestrates behavioral and metabolic responses depending on energy availability.

Binding, thermodynamics, and selectivity of a non-peptide antagonist to the melanocortin-4 receptor [PDF]

, 2018
The melanocortin-4 receptor (MC4R) is a potential drug target for treatment of obesity, anxiety, depression, and sexual dysfunction. Crystal structures for MC4R are not yet available, which has hindered successful structure-based drug design.

Global consensus on the management of melanin hyperpigmentation disorders

Journal of the European Academy of Dermatology and Venereology, Volume 40, Issue 5, Page 760-772, May 2026.
A global Delphi consensus of 10 dermatology experts established evidence‐based recommendations for melanin hyperpigmentation disorders, providing unified classification, photoprotection guidance and treatment algorithms. This framework harmonizes terminology and supports individualized management across diverse skin types and health systems.

Polymorphisms in the Melanocortin-1 Receptor (Mc1R) Gene in Vitiligo

Balkan Medical Journal, 2012
Objective: Vitiligo is a progressive skin pigmentation disorder, which may be acquired or hereditary, frequently seen, and may influence every age group. The melanocortin 1 receptor (MC1R) gene is a major determinant of human pigmentation.

Effect of NDP-a-MSH on PPAR-c and –b Expression and Anti-Inflammatory Cytokine Release in Rat Astrocytes and Microglia [PDF]

, 2013
Brain inflammation plays a central role in numerous brain pathologies. Microglia and astrocytes are the main effector cells that become activated when an inflammatory process takes place within the central nervous system. a-melanocytestimulating hormone (

Melanocortin 3 Receptors Do Not Specifically Localize to Primary Cilia in Cultured Human and Rodent Neurons

Cell Biochemistry and Function, Volume 44, Issue 4, April 2026.
ABSTRACT The melanocortin‐3 receptor (MC3R) and the melanocortin‐4 receptor (MC4R), both expressed in hypothalamic nuclei, are key downstream effectors of leptin signaling and play important roles in energy homeostasis. While pathogenic variants in the MC4R gene represent the most common cause of monogenic obesity, the clinical significance of MC3R ...

Functional Characterization of MC1R-TUBB3 Intergenic Splice Variants of the Human Melanocortin 1 Receptor.

PLoS ONE, 2015
The melanocortin 1 receptor gene (MC1R) expressed in melanocytes is a major determinant of skin pigmentation. It encodes a Gs protein-coupled receptor activated by α-melanocyte stimulating hormone (αMSH).

Corticotropin (ACTH) acts directly on amygdala neurons to down-regulate corticotropin-releasing hormone gene expression. [PDF]

, 2001
The hormone corticotropin (ACTH) is employed as therapy for diverse neurological disorders, but the mechanisms for its efficacy remain unknown. ACTH promotes the release of adrenal steroids (glucocorticoids), and most ACTH effects on the central nervous ...

Association between polymorphism in the melanocortin 1 receptor gene and E locus plumage color phenotype.

Poultry Science, 2014
The purpose of this study was to investigate the effect of the melanocortin 1 receptor (MC1R) gene on plumage color in chickens. The gene was sequenced in 77 males and 77 females from 13 Spanish breeds, carrying 6 different alleles in the E locus (E*E, E*
