This study showed that in C3H/HeJ mice, focal follicular inflammation starts before overt hair loss, with inflammation severity possibly reaching a threshold causing hair follicle dystrophy prior to visible hair loss.

This review discusses the potential of organoids in modeling COVID-19 disease and developing therapies, without reporting new results, and highlights opportunities and challenges in their application for research.

This study demonstrated that an engineered human skin equivalent can generate follicle-like structures resembling fetal skin, highlighting the role of the dermal compartment in directing epithelial cell fate in vitro.

This review addresses the role of skin-resident adult stem/progenitor cells in skin homeostasis, disease, and cancer development, and reports no new research results.

This study found that deleting the CD98hc protein in mouse skin impairs wound healing and homeostasis, resembling aging effects, due to disrupted integrin signaling pathways.

This study reports that hypomorphic alleles of the Ass1 gene in mice resemble human CTLN1, providing a potential model for preclinical studies and indicating that standard treatments for CTLN1 can rescue phenotypes.

This study observed that patients with pemphigus have a higher incidence of hypothyroidism, inflammatory bowel disease, and diabetes compared to the general population.

This study found that cyclosporine A treatment at 5 mg/kg/day may reduce inflammation and promote gland regeneration in dogs with sebaceous adenitis, though symptoms returned when treatment stopped.

Human hair follicle stem cells show signs of low oxygen levels, which may be important for hair growth and preventing baldness.

This letter to the editor discusses a potential link between new onset alopecia areata and SARS-CoV-2 infection, but reports no new clinical results.

This study demonstrates that FMOD deficiency in mice alters TGF-β ligand and receptor expression during wound healing stages, leading to delayed wound closure and increased scar size.

This article reviews the complexities and challenges in classifying systemic lupus erythematosus and the problematic role of the anti-dsDNA antibody as a biomarker, without presenting new experimental findings.

This study provides the first crystal structure of the human SRD5A2 enzyme, revealing key insights into its function and inhibition which may aid future drug development.

This study observed that CIP/KIP proteins play a significant role in regulating cell cycle arrest and differentiation in human hair follicles, supporting hair growth and formation in the anagen phase.

This study found that serine 44 in the N-terminal head domain of keratin 17 is phosphorylated in response to various stimuli affecting skin keratinocyte growth, linking K17 up-regulation with growth and stress responses in skin epithelium.

This study found that gonadal steroid hormones influence alopecia areata in C3H/HeJ mice, with estradiol promoting progression and dihydrotestosterone conferring resistance to disease onset.

This study found that lowering serum DHT levels with 5 mg finasteride daily did not significantly alter serum gonadotropin levels in healthy young men after 28 days.

This review classifies engineered nanomaterials by composition and application in biomedicine, highlighting diverse uses like regenerative medicine and potential occupational side effects, but reports no new clinical results.

In this study, researchers identified a novel congenital skin disorder in Chesapeake Bay retrievers, linked to a plakophilin-1 deficiency due to a genetic mutation, marking the first known occurrence in an animal species.

This study identified that rose, thyme geraniol, palmarosa, and tolu balsam essential oils activate TRPV1, with citronellol and geraniol as newly recognized agonists.

This study found that Sp6 overproduction in ameloblast-lineage cells increased cell proliferation and ameloblastin expression, suggesting that Sp6 promotes amelogenesis by inhibiting follistatin gene expression.

In this study using rats, finasteride-induced DHT deficiency led to morphological changes in seminiferous tubules, linked with altered junctional protein expression, potentially impairing fertility.

This article reviews the association between hepatitis C virus and systemic disorders like mixed cryoglobulinemia, highlighting potential autoimmune side effects from interferon-a2b treatments, and reports no new clinical results.

This review discusses how neuroendocrine pathways influence keratin regulation in human skin and hair follicles and suggests these pathways as potential targets for new treatments of skin disorders, but reports no clinical results.

In this study, topical application of the SCD1 inhibitor XEN103 significantly reduced sebaceous gland size and number in mouse skin, suggesting potential local therapeutic effects for acne treatment without systemic side effects.

This study found that NFI-C plays a crucial role in the transition from the telogen to anagen phase of the hair follicle cycle, affecting hair growth initiation in mice.

This study found that using ectopic expression of CD24 is a promising approach for selecting genetically modified human epidermal stem cells for safe cutaneous gene therapy in cancer-prone conditions.

In this study, mutations in the vitamin D receptor were identified in Brazilian children with rickets and alopecia, leading to impaired receptor activation and reduced 24-hydroxylase expression.

This study, using multimodal profiling in mice, found that various tissues contain unique γδ T cell subsets adapted to their environment, revealing their functional diversity, lineage relationships, and similarities to CD8+ tissue-resident memory T cells.

This study describes a distinct pattern of trichoscopic features associated with chemotherapy-induced alopecia and how these features evolve through different phases of chemotherapy treatment.
