This review discusses the complex causes and treatment challenges of chronic inflammatory skin diseases, emphasizing the need for biomarkers to predict treatment responses; it reports no new clinical results.

This review discusses potential mechanisms contributing to higher COVID-19 mortality among men, particularly the roles of smoking, genetic factors, and reproductive hormones, without presenting new clinical findings.

This study demonstrated that EdnrB signaling promotes melanocyte stem cell proliferation and differentiation, enhancing hair and epidermal melanocyte regeneration, especially under conditions of active Wnt signaling.

This study found that AR/VDR-targeted agonist hormone therapy can inhibit cell viability in HR2-av triple-negative breast cancer cell lines through multiple mechanisms and may enhance the effects of chemotherapy.

This study found that dual inhibition of BACE1 and BACE2 in mice affects melanosome maturation and causes dose-dependent hair depigmentation without altering retinal morphology.

In this study, enteroendocrine cells were shown to coordinate intestinal stem cell migration towards a wound in Drosophila by releasing a ligand that activates non-canonical Wnt signaling, aiding efficient tissue repair.

This study found that cyclosporin A treatment enhances hair growth in mice by inhibiting calcineurin-NFAT1 activity, which alters keratinocyte differentiation and apoptosis-related gene expression in hair follicles.

This review found that JAK/STAT pathway inhibitors, such as tofacitinib and ruxolitinib, led to symptom improvement in all observed atopic dermatitis cases, but responses were mixed for vitiligo and alopecia areata, with a generally mild safety profile reported.

This review discusses strategies to enhance mesenchymal stem cell therapy effectiveness but reports no new clinical results; it highlights the need for improved consistency and efficacy in MSC-based treatments.

This study found that oxidative damage is present in the mitochondria of PolG mice, which exhibit premature aging-like phenotypes due to mitochondrial dysfunction.

This study found that the microRNA miR-22 is a key regulator of the hair cycle, influencing hair loss by promoting the transition from growth to rest phases and repressing keratinocyte differentiation.

In this study, tofacitinib treatment was associated with significant hair regrowth in two patients with alopecia universalis over eight months, with minimal adverse effects reported.

In this study, mice exposed to prolonged space conditions demonstrated skin atrophy, altered hair follicle cycles, and significant changes in the gene expression associated with skin muscle health.

In this review, researchers explored the roles of vitamins A, B3, C, D, and E in skin immunity, highlighting their potential as therapeutics for skin diseases due to their antioxidant, anti-inflammatory, and antimicrobial properties.

This article reviews mechanisms by which herbal ingredients may stimulate or inhibit hair growth, and it reports no new clinical findings while suggesting potential for developing hair loss treatments.

This review discusses the role of pharmacological sciences in advancing regenerative medicine technologies but reports no new experimental findings; the authors advocate for increased pharmacologist involvement to drive innovations.

This review explores genetic and lifestyle factors influencing hair diversity and reports no new findings, calling attention to the potential for future discoveries in genetic and epigenetic research.

This study found that overexpressing human Bcl-2 in mice protected epidermal keratinocytes from UVB-induced apoptosis but unexpectedly increased apoptosis during hair follicle regression and chemotherapy.

This review discusses the genetic research developments in androgenetic alopecia, reporting no new clinical results, and highlights the potential for discovering novel therapeutic targets.

This review discusses the potential of plant polyphenols to overcome multidrug resistance in various solid cancers and reports no new experimental results; further research is suggested.

In this study, the researchers reported that activin B combined with bone marrow-derived mesenchymal stem cells enhanced wound healing and hair follicle regeneration in rats by promoting cell migration through the ERK and JNK pathways.

This study found that the signaling peptide CLE40 and receptor proteins CLV2 and CRN regulate root meristem differentiation through two distinct, antagonistic pathways activated by CLE40 in a dose-dependent manner.

This study found that reducing BMP signaling in mouse nipple epithelia, achieved through Noggin overexpression, can convert them into hairy skin with pilosebaceous units.

This review focuses on neuroactive steroids' influence on GABA-ergic signaling and discusses challenges in developing them for various therapeutic uses, citing recent excitement from FDA approval of allopregnanolone for postpartum depression but reporting no new results.

This study suggests that chronic stress can lead to decreased skin pigmentation in mice by disrupting the skin's HPA axis, potentially making stress a risk factor for depigmentation.

The researchers reported that in mice, prolactin signaling in the skin epithelium inhibits hair follicle stem cell activation, promoting quiescence during periods of high serum prolactin like pregnancy and lactation.

This review discusses the potential use of cultured primary fetal cells from a single organ donation to produce therapeutic products, emphasizing the need for process consistency and safety verification, but reports no clinical results.

This study found that combining platelet-rich plasma with adipose-derived mesenchymal stem cells significantly improved diabetic wound healing in rats by enhancing angiogenesis and modulating the Notch signaling pathway.

This review discusses three newly identified forms of epidermolysis bullosa related to mutations in DST-e, EXPH5, and ITGA3, offering insights into their genetic and clinical characteristics but reports no new clinical results.

This review discusses findings from genetic studies on acne, highlighting progress in understanding its molecular pathogenesis without reporting new clinical results.
