This review summarizes recent advancements in follicular targeting for drug delivery via hair follicles and calls for pilot studies in humans to explore potential clinical applications.

This review discusses the role of intrinsic skin signals, rather than serum signals, in regulating melanin synthesis and hair pigmentation, but reports no new experimental data.

This study found that recombinant human leukocyte interferon alfa-2a achieved a 64% overall antitumor response rate in patients with early and advanced cutaneous T cell lymphoma and was generally well-tolerated.

This review discusses the complexities of diagnosing and treating iron deficiency related to nutritional anemia and hair loss, concluding that routine screening and supplementation for hair loss are not yet supported by sufficient evidence.

This review discusses the multifaceted actions of metformin in polycystic ovary syndrome and reports no new clinical results; the authors emphasize metformin's potential benefits in both cardiometabolic and reproductive aspects of PCOS.

The researchers reported that hair follicle development and commensal microbe colonization promote the accumulation of regulatory T cells in neonatal skin, with the Ccl20-Ccr6 pathway playing a key role in this process.

This study reviewed recent theories on alopecia areata's pathogenesis, highlighting its autoimmune nature due to immune privilege disruption in hair follicles, and noted current treatments have limited efficacy with high relapse rates, underscoring the need for further research into its mechanisms for better therapies.

This review discusses the role of regulatory T-cells in tissue repair and regeneration across various organs and reports no new clinical results.

This review discusses biological sex differences in COVID-19 outcomes and reports no new clinical results; it identifies a need for studies to clarify how sex influences disease progression.

This review discusses melatonin's potential in dermatology, highlighting its antioxidative, immunomodulatory, and DNA repair properties, but reports no new clinical results.

This review discusses the regulation and function of vitamin D and its receptor in skin cells, highlighting their roles in processes such as proliferation inhibition, differentiation, and innate immunity, but reports no new results.

This review discusses alopecia areata as a model for studying tissue-directed autoimmune diseases and reports no new clinical findings.

This article discusses advancements in understanding how skin stem cells and fibroblasts contribute to scar formation, highlighting current and potential therapies aimed at preventing or reducing scarring, yet notes that effective treatments without significant side effects are still lacking.

This study identified a distinct cytokine activation signature in alopecia areata, involving TH2, TH1, IL-23, and IL-9/TH9 pathways, suggesting potential targeting strategies similar to those in psoriasis and atopic dermatitis.

This study found that TRPV1 activation in human scalp hair follicles inhibited hair shaft elongation, suppressed proliferation, and induced apoptosis, suggesting TRPV1 as a potential target for managing hair growth and epithelial disorders.

In this study, researchers found that substance P triggered premature catagen development and immune changes in human scalp hair follicles, providing a possible biological link between stress and hair loss conditions like telogen effluvium and alopecia areata.

This review examines the functions of vitamin D and its receptor in skin and explores how these are regulated, reporting no new clinical results.

This review explores the causes and mechanisms of alopecia areata and discusses current treatments, reporting no new clinical findings.

This study found that 'smart' peptide hydrogels improved wound healing in a rat model of partial thickness burns, achieving greater wound closure and faster debridement compared to a standard treatment.

This study reported that transgenic mice with targeted TNF alpha expression in keratinocytes showed impaired weight gain, retarded hair growth, and skin changes, leading to cachexia and necrosis.

This article discusses the distinct skin findings associated with lupus erythematosus, noting that some are specific to lupus while others are nonspecific and occur with various diseases; it reports no new results.

This review discusses the immune roles of keratinocytes in wound healing and chronic wound inflammation, emphasizing their potential impact on chronic wound pathology and highlighting areas for future research.

This study observed that quiescent label-retaining cells in the intestine, identified by Paneth cell markers, can switch to a proliferative state and activate Bmi1 expression during tissue injury, contributing to tissue regeneration.

This study found that cathepsin L deficiency in mice led to significant abnormalities in hair follicle development and cycling, including disrupted hair shaft outgrowth and premature hair growth phase entry.

This article outlines manifestations of systemic lupus erythematosus, noting rapid joint symptom improvement with corticosteroids and antimalarial drug responsiveness for skin symptoms, and links anti-Ro with photosensitive rash and subacute lupus.

This review summarizes proposed pathophysiological mechanisms of postpartum depression, highlighting neuroendocrine and neurobiological changes, but reports no new findings and calls for integrated understanding of the disorder.
