Mast cell subsets and neuropeptides in leprosy reactions

Arquivos de Neuro-Psiquiatria, 2003
The immunohistochemical identification of neuropeptides (calcitonin gene-related peptide, vasoactive intestinal polypeptide, substance P, alpha-melanocyte stimulating hormone and gamma-melanocyte stimulating hormone) quantification of mast cells and ...

The Alpha-Melanocyte Stimulating Hormone Induces Conversion of Effector T Cells into Treg Cells

Journal of Transplantation, 2011
The neuropeptide alpha-melanocyte stimulating hormone (α-MSH) has an important role in modulating immunity and homeostasis. The production of IFN-γ by effector T cells is suppressed by α-MSH, while TGF-β production is promoted in the same cells.

Treatment options for immune‐related adverse events associated with immune checkpoint inhibitors

British Journal of Pharmacology, EarlyView.
Abstract The immunotherapy revolution with the use of immune checkpoint inhibitors (ICIs) started with the clinical use of the first ICI, ipilimumab, in 2011. Since then, the field of ICI therapy has rapidly expanded — with the FDA approval of 10 different ICI drugs so far and their incorporation into the therapeutic regimens of a range of malignancies.

Dual Role of Natural Killer Cells in Early Pregnancy: Immunopathological Implications and Therapeutic Potential in Recurrent Spontaneous Abortion and Recurrent Implantation Failure

Cell Proliferation, EarlyView.
This article elaborates on the role of NK cells in early pregnancy from multiple perspectives, including molecular mechanisms and therapeutic interventions. It also discusses how NK cell dysfunction contributes to RSA and RIF, aiming to provide insights for future research on NK cell mechanisms and clinical treatment of RSA and RIF.

Establishment and Validation of a C57BL/6J Mouse Model for Melasma

Cell Proliferation, EarlyView.
A melasma‐like mouse model was established in C57BL/6J mice using a combination of UVB irradiation, progesterone administration, and chronic psychological stress. This model replicates key clinical features and biomarker alterations observed in human melasma. Importantly, it is fundamentally distinct from UV‐induced post‐inflammatory hyperpigmentation (

α-Melanocyte stimulating hormone promotes muscle glucose uptake via melanocortin 5 receptors

Molecular Metabolism, 2016
Objective: Central melanocortin pathways are well-established regulators of energy balance. However, scant data exist about the role of systemic melanocortin peptides. We set out to determine if peripheral α-melanocyte stimulating hormone (α-MSH) plays a

An α-Melanocyte–Stimulating Hormone Analogue in Erythropoietic Protoporphyria

New England Journal of Medicine, 2009
To the Editor: Patients with erythropoietic protoporphyria, a rare inherited disease, accumulate photosensitizing protoporphyrin in the dermis, which results in severe dermal pain and incapacitating phototoxic reactions when the skin is exposed to visible light, primarily blue light (the Soret band, with the strongest absorbance among the porphyrins).1

Estrogen synthesized in the central nervous system enhances MC4R expression and reduces food intake

The FEBS Journal, EarlyView.
Estrogen is regulated by the rate‐limiting enzyme aromatase. This study examines how neuroestrogens, estrogen produced in the brain, regulate appetite through the hypothalamus. Using ovariectomized, aromatase knockout, and brain‐specific aromatase‐restored mice, the study found that neuroestrogens suppress appetite by influencing genes like Mc4r.

Therapeutic Effects of Stimulating the Melanocortin Pathway in Regulating Ocular Inflammation and Cell Death

Biomolecules
Alpha-melanocyte-stimulating hormone (α-MSH) and its binding receptors (the melanocortin receptors) play important roles in maintaining ocular tissue integrity and immune homeostasis.
