Article Abstract
In the present study, a pH responsive dendritic polyglycerol nanogel (dPG-NG) is developed to measure the pH values inside the hair follicle (HF) using an ex vivo porcine ear model. The macromolecular precursors are labeled with a pH sensitive indodicarbocyanine dye (pH-IDCC) and a control dye (indocarbocyanine dye: ICC) and crosslinked via a mild and surfactant-free Thiol-Michael reaction using an inverse nanoprecipitation method. With this method, it is possible to prepare tailor-made particles in the range of 100 nm to 1 µm with a narrow polydispersity. The dPG-NGs are characterized using dynamic light scattering, nanoparticle tracking analysis, and atomic force microscopy. Systematic analysis of confocal microscope images of histological sections of the skin enables accurate determination of the pH gradient inside the HF. The results show that these novel pH-nanosensors deeply penetrate the skin via the follicular pathway and the pH of the pig hair follicles increase from 6.5 at the surface of the skin to 7.4 in deeper areas of the HF. The pH-nanosensor shows no toxicity potentials.

The prevalence of AGA is continuously rising, with an earlier age of onset. Currently, only minoxidil and finasteride have received FDA approval for the treatment of AGA, inadequately addressing the pressing clinical needs. Recently, the involvement of the Wnt/β-catenin signaling pathway in AGA has attracted increased research interest.

Background: Persistent chemotherapy-induced alopecia (pCIA) is a distressing side effect of antineoplastic agents, imposing significant psychological burdens on cancer survivors. Despite its impact, there are no standardized guidelines for diagnosis, prevention or management.
Objective: To establish consensus-based definitions, diagnostic criteria, grading systems and management recommendations for pCIA.

Follicular unit extraction (FUE) has become a leading technique in hair transplantation, yet optimal management of the donor area remains a clinical challenge. This systematic review analyzes intraoperative and postoperative interventions applied to the donor area in FUE hair transplantation, with a focus on both clinical outcomes and the cellular and molecular mechanisms involved in tissue repair, inflammatory response, and regenerative processes. A comprehensive literature search was conducted in PubMed and EMBASE (January 2000-June 2025), identifying clinical studies that evaluated donor area treatments and reported outcomes related to healing, inflammation, infection, and patient satisfaction.

Diabetic infected wounds represent a formidable clinical challenge characterized by persistent hyperglycemia-induced pathological cascades that disrupt normal healing processes through multiple mechanisms including chronic inflammation, oxidative stress, and microvascular dysfunction. As prototypical chronic wounds, they exhibit severely impaired tissue regeneration due to this multifaceted dysfunction in both skin architecture and biological function. Metal-organic frameworks (MOFs) have emerged as promising next-generation therapeutic platforms owing to their exceptional structural tunability, multifunctional properties, and precise spatiotemporal drug delivery capabilities.

Background: Bullous Pemphigoid (BP) is caused by a predominantly Th2-mediated attack on the basement membrane by the production of anti-BP180 and anti-BP230 antibodies. Malignant tumors can exacerbate immune disorders through a variety of potential pathways, including pro-inflammatory responses in the tumor microenvironment, cross-immune responses induced by tumor-associated antigens, and the lifting of immunosuppressive states and activation of underlying autoimmune responses after surgery. Alopecia Areata (AA) is an autoimmune disease caused by T-lymphocyte-mediated destruction of the immune privilege of the hair follicle, specifically involving the immune axes of Th1, Th2 and Th17.
