We highlight the particular aspects of the stable gastric pentadecapeptide BPC 157 pleiotropic beneficial activity (not destroyed in human gastric juice, native and stable in human gastric juice, as a cytoprotection mediator holds a response specific…
Copper peptides (GHK-Cu) are a powerful hair growth promoter with minimal side effects when compared with minoxidil and finasteride; however, challenges in delivering GHK-Cu topically limits their non-invasive applications. Using theoretical calculat…
Device infection remains a dreaded and increasingly common complication of pacemaker procedures, often mandating removal of all implanted materials. Intensive wound management may be necessary following extraction, requiring multiple follow-up encoun…
The hyphenation of the separation technique with the high-sensitive mass spectrometry detection is one of the driving forces of modern analysis enabling measurements in complex matrices. In particular, capillary electrophoresis coupled to inductively…
Background and objective Scalp dandruff, a prevalent dermatological condition marked by flaking and itching, affects a large segment of the population. Sun exposure, genetics, and dryness, along with winter conditions, indoor heating, and hard water,…
Silicosis is the most common type of pneumoconiosis, having a high incidence in workers chronically exposed to crystalline silica (CS). No specific medication exists for this condition. GHK, a tripeptide naturally occurring in human blood and urine,…
Common features of neurodegenerative diseases are oxidative and inflammatory imbalances as well as the misfolding of proteins. An excess of free metal ions can be pathological and contribute to cell death, but only copper and zinc strongly promote pr…
Peptides are recognized as highly effective and safe bioactive ingredients. However, t their practical application is limited and hampered by harsh conditions for practical drug delivery. Hence, a novel peptide nanocarrier of copper peptide (GHK-Cu)…
Alzheimer's disease (AD) is a complex neurodegenerative disease and a leading cause of morbidity and mortality. Efforts to find disease modifying treatments have met with limited success. The naturally occurring peptide GHK (glycyl-L-histidyl-L-lysin…
Fibrotic disorders, such as idiopathic pulmonary fibrosis, are characterized by the accumulation of myofibroblasts, cells responsible for excessive extracellular matrix deposition and tissue remodeling. The inability to terminate this reparative proc…
BACKGROUND: Cathelicidin has been correlated with the pathophysiology of atopic dermatitis (AD). An indirect correlation of vitamin D with the course of the disease has already been reported as it directly affects the levels of cathelicidin. The purp…
AIMS: Atherosclerosis is a chronic inflammatory disease of the arteries leading to the formation of atheromatous plaques. Human mesenchymal stem cells (hMSCs) are recruited from the circulation into plaques where in response to their environment they…
Cathelicidin peptides secreted by leukocytes and epithelial cells are microbicidal but also regulate pathogen sensing via toll-like receptors (TLRs) in the colon by mechanisms that are not fully understood. Herein, analyses with the attaching/effacin…
BACKGROUND: The antimicrobial peptides (AMPs) played a critical role in the innate immunity of the host and are considered natural sources illustrating a broad-spectrum antimicrobial activity with high specificity and low cytotoxicity. AMPs generally…
Solid-state NMR (ssNMR) spectroscopy facilitates the non-destructive characterization of structurally heterogeneous biomolecules in their native setting, for example, comprising proteins, lipids and polysaccharides. Here we demonstrate the utility of…
Although vitamin D (VD) is known to have multiple effects on the skin and immunity, its effects on atopic dermatitis (AD) severity remain unclear. We investigated whether oral cholecalciferol (VD3) supplementation changes stratum corneum expression o…
Antimicrobial peptides are becoming a new generation of antibiotics due to their therapeutic potential and ability to decrease drug-resistant bacteria development. Cathelicidins are known as effective peptides of vertebrate immunity that play crucial…
BACKGROUND: Rosacea, a chronic inflammatory disorder of the facial skin, is effectively treated by intense pulsed light (IPL). OBJECTIVE: To explore the potential molecular mechanism underlying the photobiomodulation effect of IPL for rosacea treatme…
Cathelicidin antimicrobial peptides are a diverse family of cationic amphipathic peptides with multiple activities. In humans, cathelicidin LL-37 is one of the main host defense peptides with a remarkable medical and biotechnological potential. Dereg…
