α-Melanocyte-stimulating hormone (α-MSH), an anti-inflammatory and immunomodulatory neuropeptide, has been shown to be effective in the experimental treatment of autoimmune diseases and allograft rejection. However, its regulatory mechanism is still unclear. Mature dendritic cells (DCs) are pivotal initiators of immune response and inflammation. We hypothesized that the regulatory role of α-MSH...

AIMS Oxidative stress and apoptosis are among the earliest lesions of diabetic retinopathy. This study sought to examine the anti-oxidative and anti-apoptotic effects of α-melanocyte-stimulating hormone (α-MSH) in early diabetic retinas and to explore the underlying mechanisms in retinal vascular endothelial cells. METHODS Sprague-Dawley rats were injected intravenously with streptozocin to i...

Sunburn, wound repair, and chronic renal failure with hemodialysis are usually accompanied by both pigmentation and itching. Proopiomelanocortin-derived α-melanocyte-stimulating hormone (α-MSH) is produced in response to external stimuli, such as UV irradiation, and is involved in cutaneous pigmentation. However, it is unclear whether α-MSH is also involved in the itching. We therefore investig...

α-Melanocyte-stimulating hormone (α-MSH) is responsible for pigment dispersion in the chromatophores of fish and other tetrapods such as amphibians and reptiles. Recently, we discovered that α-MSH did not always stimulate pigment dispersion because this hormonal peptide exerted no effects on the melanophores of flounders. We assumed that the reduction of α-MSH activity was related to the co-exp...

Alpha-melanocyte stimulating hormone (α-MSH) is involved in normal skin wound healing and also has anti-inflammatory properties. The association of α-MSH to polyelectrolyte layers with various supports has been shown to improve these anti-inflammatory properties. This study aimed to evaluate the effects of nanofibrous membrane functionalized with α-MSH linked to polyelectrolyte layers on gingiv...

The aim of the study was to investigate dynamic changes in α-melanocyte-stimulating hormone (α-MSH) levels in the serum of patients with craniocerebral trauma. Forty-eight patients with acute craniocerebral injury were selected between January 2015 and October 2016. The patients were divided into three groups: severe (18 cases), moderate (16 cases) and mild (14 cases), according to the Glasgow ...

Rheumatoid cachexia is associated with rheumatoid arthritis and it increases mortality and morbidity. Adjuvant-induced arthritis is an experimental model of rheumatoid arthritis that causes anorexia and muscle wasting. α-Melanocyte-stimulating hormone (α-MSH) has anti-inflammatory actions, and it is able to decrease inflammation in several inflammatory diseases including experimental arthritis....

The production of melanin is regulated by α-melanocyte-stimulating hormone (α-MSH), which is produced from proopiomelanocortin (POMC). Keratinocytes release POMC along with lower levels of α-MSH and ACTH. To clarify the mechanism of melanogenesis after ultraviolet (UV)-irradiation, this study focused on the expression of POMC and POMC-derived peptides after UV-irradiation. Western blot analysis...

Melanoma is a malignancy with high potential to invasion and treatment resistance. The α -melanocyte-stimulating hormone ( α -MSH) signal transduction involving Wnt/ β -catenin, c-Kit, and microphthalmia-associated transcription factor (MITF), a known pathway to produce melanin, has been demonstrated as one of cancer stem cell characteristics. This study was aimed to examine the effect of resve...

background:chronic active adrenocorticotropin hormone (acth) immunization of ewes (with a previous history of immunization) resulted in elevated titres of antibody against acth, which induced a reduction in circulating levels of cortisol. objectives:the aim of the present study was to investigate: a) the influence of active immunization against acth on milk production of the ewe as assessed by ...
