A tripeptide (Lys-Pro-Val) derived from alpha-MSH, studied for its anti-inflammatory, wound healing, and gut protective properties.
The presence of the ancient anti-inflammatory peptide alpha-melanocyte-stimulating hormone [alpha-MSH (1-13), SYSMEHFRWGKPV] in barrier organs such as gut and skin suggests a role in the nonspecific (innate) host defense. alpha-MSH and and its carbox…
The presence of the ancient peptide alpha-melanocyte-stimulating hormone (alpha-MSH) in barrier organs such as gut and skin suggests that this potent anti-inflammatory molecule may be a component of the innate host defense. In tests of antimicrobial…
Alpha-melanocyte-stimulating hormone (alpha-MSH), a neuroimmunomodulatory peptide of ancient origin, is known to be involved in the control of host responses. In inflammatory cells, in the periphery and within the central nervous system, alpha-MSH mo…
Alpha-melanocyte stimulating hormone (alpha-MSH) is an ancient tridecapeptide with potent inhibitory activity in all major forms of inflammation. The anti-inflammatory message sequence of alpha-MSH resides in the COOH-terminal tripeptide alpha-MSH[11…
Inflammatory processes contribute to neurodegenerative disease, stroke, encephalitis, and other central nervous system (CNS) disorders. Activated microglia are a source of cytokines and other inflammatory agents within the CNS and it is therefore imp…
It is clear that inflammatory processes contribute to neurodegenerative disease, stroke, closed head injury, encephalitis, and other CNS disorders. These inflammatory processes are marked by local increases in cytokines, in particular tumor necrosis…
Melanocortins are proopiomelanocortin-derived peptides that include adrenocorticotropic hormone [ACTH (1-39)], alpha-melanocyte-stimulating hormone [alpha-MSH (1-13)], and related amino acid sequences. Melanocortin peptides have potent antiinflammato…
The antiinflammatory effects of alpha-melanocyte-stimulating hormone (alpha-MSH) molecules, specifically alpha-MSH(1-13) and its COOH-terminal tripeptide alpha-MSH(11-13), are well established. The peptides have been effective in tests of all major m…
Cardiomyopathy related to ethanol abuse is often accompanied by cigarette use. To examine if the major cardioactive component may intensify the abnormal function and composition induced by chronic ethanol, nicotine was administered orally, 2.5 mg bid…
alpha-Melanocyte-stimulating hormone (MSH) antagonizes the binding of interleukin-1 beta (IL-1) to its type I receptors on T cells. IL-1 modulates insulin secretion in the insulin-secreting tumor cell line, HIT-T 15 cells. In the present studies, we…
The neuropeptide alpha-melanocyte-stimulating hormone (alpha-MSH) has potent antipyretic and antiinflammatory properties. When administered systemically, the naturally occurring molecule and its COOH-terminal tripeptide sequence inhibit inflammation…
Interleukin-1 (IL-1) is a proinflammatory cytokine, alpha-MSH(1-13) molecules inhibit inflammation induced by cytokines, other mediators of inflammation, and by peripheral irritants. D-valine substitution in the antiinflammatory/antipyretic message s…
Interleukin-1 beta (IL-1), a cytokine released from inflammatory cells, is thought to be involved in the anorexia associated with severe infection. To assess a possible role of the amino acid sequence found in the supposed IL-1 receptor binding sites…
The neuropeptide alpha-melanocyte stimulating hormone [alpha-MSH(1-13)] occurs in the pituitary, brain, skin and other tissues and receptors for this molecule are likewise widespread. In previous research, this tridecapeptide, which shares its amino…
D-Amino acid substitutions in the anti-inflammatory/antipyretic Ac-alpha-MSH(11-13)-NH2 tripeptide of Ac-alpha-MSH(1-13)-NH2 were made and the altered peptides were injected in mice treated with picryl chloride. Ear swelling, measured 3 and 6 h after…
Alpha-melanocyte stimulating hormone [alpha-MSH(1-13)] occurs within the CNS, skin, circulation and in other body sites. This tridecapeptide and its COOH-terminal tripeptide, alpha-MSH (11-13), have antipyretic and anti-inflammatory actions. Studies…
The endogenous neuropeptide alpha-melanocyte stimulating hormone (alpha-MSH 1-13), previously found to have marked antipyretic activity, inhibits histamine-induced increases in vasopermeability. The primary antipyretic amino acid message sequence is…
alpha-Melanocyte stimulating hormone (alpha-MSH 1-13) has marked antipyretic effects when administered centrally or peripherally in small doses. A C-terminal fragment, alpha-MSH (11-13), contains an antipyretic message sequence of alpha-MSH; however,…
In previous experiments, alpha-MSH (1-13) and ACTH (1-24), which contains the alpha-MSH 1-13 amino acid sequence, were found to reduce fever after central and peripheral administration of low, non-hypothermic doses. Shorter molecules, including alpha…
