The melanocortins (MCs) are a family of multifunctional peptidergic hormones. Several superpotent, prolonged acting, enzymatically resistant, MC analogs have been designed and synthesized to help clarify the nature and role of MCs and their receptors…
We report complete transection of major muscle and the systemic peptide treatment that induces healing of quadriceps muscle promptly and then maintains the healing with functional restoration. Initially, stable gastric pentadecapeptide BPC 157 (GEPPP…
Stable gastric pentadecapeptide BPC 157 (BPC 157, as an antiulcer agent in clinical trials for inflammatory bowel disease; PLD-116, PL 14736, Pliva, no toxicity reported) alone (without carrier) ameliorates healing of tendon and bone, respectively, a…
BACKGROUND: Alcohol disturbances, NO stimulation (by the NO-precursor L-arginine), and/or NO-synthesis blockade (by N(G)-nitro-L-arginine methyl ester, i.e. L-NAME) were challenged with stable gastric pentadecapeptide BPC 157, which inhibits both acu…
Gastric pentadecapeptide BPC 157 (GEPPPGKPADDAGLV, M.W. 1419, safe in clinical trials for inflammatory bowel disease (PL 10, PLD 116, PLD 14736, Pliva, Croatia)) has a particular cytoprotective/adaptive cytoprotective activity. The cytoprotective/ada…
We report a simple novel rat model that combines prolonged esophagitis and parallel sphincters failure. The anti-ulcer gastric pentadecapeptide BPC 157, which was found to be stable in gastric juice, and is being evaluated in inflammatory bowel disea…
OBJECTIVE: To evaluate the role of skin care products that contain a copper tripeptide complex, glycyl-l-histidyl-l-lysine-Cu(2+) (GHK-Cu), in treating carbon dioxide (CO(2)) laser-resurfaced skin. METHODS: Patients meeting the inclusion criteria und…
Recent studies have indicated that ghrelin stimulates growth hormone release from the pituitary via the growth hormone secretagogue receptor (GHSR). We have previously isolated two GHSR subtypes from the pituitary of the black seabream Acanthopagrus…
CONTEXT: Pulsatile GH secretion is considered important for many of the hormone's physiological effects. Short-term GHRH infusions enhance GH pulsatility and increase IGF-I, but the short GHRH half-life limits its therapeutic use. A synthetic GHRH an…
Although the majority of children with isolated growth hormone (GH) deficiency have a good growth response to GH-releasing hormone (GHRH), the use of this therapeutic agent is limited by its very short half-life. Indeed, we have shown that, in mice w…
CONTEXT: Therapeutic use of GHRH to enhance GH secretion is limited by its short duration of action. OBJECTIVE: The objective of this study was to examine the pharmacokinetic profile, pharmacodynamic effects, and safety of CJC-1295, a long-acting GHR…
Mammalian milk possesses inherent antimicrobial properties that have been attributed to several diverse molecules. Recently, antimicrobial peptides that belong to the cathelicidin gene family have been found to be important to the mammalian immune re…
Host defense peptides (often called cationic antimicrobial peptides) have pleiotropic immunomodulatory functions. The human host defense peptide LL-37 is up-regulated at sites of infection and has little or no antimicrobial activity in tissue-culture…
Most antimicrobial peptides have been discovered based on activity-guided purification procedures, which used assays to determine their antimicrobial activity. Nevertheless, recent studies have shown that antimicrobial peptides also exert a range of…
Human cathelicidin antimicrobial protein hCAP18/LL-37 is an effector molecule of the nonspecific innate immune system. hCAP18/LL-37 is present in leukocytes and is expressed in skin and other epithelia, where it is upregulated in association with inf…
LL-37 is a human cationic host defense peptide that is an essential component of innate immunity. In addition to its modest antimicrobial activity, LL-37 affects the gene expression and behavior of effector cells involved in the innate immune respons…
Mastitis is a major economic concern for the dairy industry. Conditions such as parturition cause a transient immunosuppression that leads to increased incidence of mastitis. One facet of periparturient immunosuppression is a functional impairment of…
The cathelicidin family of host defense peptides includes a group of cationic and usually amphipathic peptides that display a variety of activities related to host defense functions, among which the most acknowledged is a direct antimicrobial activit…
In this work, the intein fusion approach was used for expression and purification of cathelicidin-like peptide SMAP-29 from Escherichia coli cultures. To overcome the high toxicity of the antimicrobial peptide against host cells, both C- and N-termin…
