This article reviews the role of vasoactive intestinal peptide in maintaining immune privilege in hair follicles and does not report new findings; the authors propose it as essential for immune homeostasis in alopecia areata.

GLP-1 RA medications may be linked to hair loss.

This study found that a topical cream containing PTH (7–34) significantly stimulated hair growth in hairless mice.

This article reviews the role and clinical applications of 1,25-dihydroxyvitamin D3 and parathyroid hormone-related peptide in dermatology, with a focus on psoriasis treatment, and reports no new experimental findings.

This study found that topical minoxidil and diazoxide induced significant hair regrowth in bald macaques, while a steroid 5 alpha-reductase inhibitor prevented baldness in preadolescent macaques.

RADA16-I can effectively deliver and release mangiferin, improving its solubility and bioavailability.

This study found that a novel peptide, FOL-005, derived from osteopontin, significantly inhibited hair growth in human hair follicles both ex vivo and in vivo, suggesting potential as a treatment for unwanted hair growth.

This study found that genetically variant peptides from human hair can reliably identify individuals despite differences in age and storage conditions, provided environmental and processing factors are controlled.

Soymetide-4 from soy can prevent hair loss caused by a cancer drug in rats.

This review discusses how recent advancements in computational and lab-based methods have enhanced peptide drug discovery, noting the efficiency and cost benefits over traditional approaches and the potential for targeting difficult protein interactions, including protein degradation using proteolysis-targeting chimeras.

This study found that incorporating cell-adhesive ligands into 3D peptide hydrogels supports the survival and osteogenic differentiation of human amniotic mesenchymal stem cells.

This study introduced a new adaptive microrhizotron for non-destructive observation of pepper root traits, finding that specific installation patterns significantly enhanced root interception probability while effectively measuring root architecture for plant research.

This study found that immunity to self-prion peptides could be induced in Lewis rats, but in older rats, it was associated with severe skin inflammation and hair loss.

In this study, researchers isolated multipotent stem cells from elderly human epidermis and showed that they could differentiate into neurons using TAT-VHL peptide, suggesting potential for regenerative therapies.

In this study, a peptide hydrogel scaffold loaded with umbilical cord-derived mesenchymal stem cells was used to repair damaged endometrium in rats, significantly improving fertility and live birth rates by restoring endometrial thickness and promoting angiogenesis.

In this study, Bioactive Collagen Peptides supplementation increased hair follicle cell proliferation and improved hair thickness in healthy women over 16 weeks compared to a placebo.

In a study on female SD rats, the authors found that RADA16-1 short-peptide nano-fiber gel scaffolds improved burn wound healing, hair follicle growth, hair growth length, and expression of bFGF and EGF compared to a NaCl control.

This study suggests that while PTH rP initially seemed to shorten the hair cycle by transitioning hair follicles from anagen to catagen, more relevant models indicate it ultimately accelerates and stimulates hair growth.

This review discusses the roles of adiponectin and bradykinin in skin homeostasis and pathologies, highlighting the need for further research into their therapeutic potential but reports no new clinical results.

The study found that Sh-Polypeptide 9, a biomimetic peptide, enhances endothelial tubulogenesis and VEGF production more effectively than minoxidil, particularly at low concentrations, suggesting potential for hair follicle vascularization.

This study demonstrated that water-soluble peptides from egg yolk, termed "hair growth peptide," stimulated human hair follicle cell growth and improved hair growth in female pattern hair loss.

This study reported that the use of composite RGDmix hydrogel improved the survival and proliferation of human amniotic mesenchymal stem cells and increased growth factor expression, enhancing wound healing through the RGDSP/integrin αv/PI3K/AKT signaling pathway.

This study found that two short peptides derived from pigment epithelium-derived factor significantly accelerated full-thickness skin wound healing in mice through mechanisms that may involve increased cell proliferation and stem cell mobilization.

This study developed a carbohydrate chitosan-based biomaterial combined with a novel peptide to promote the chondrogenic differentiation of human adipose-derived stem cells, suggesting potential clinical applications for cartilage regeneration.

This study found that a specific fragment of AIMP1, secreted by hair follicle stem cells, activated dermal papilla cells, leading to enhanced hair regrowth and maintenance in mice.
