This study suggests that the secretome from amniotic fluid-derived mesenchymal stem cells overexpressing Nanog could stimulate hair growth and increase follicle density, potentially aiding in alopecia treatment.

This study found that isolated red light may serve as an alternative for photo-immunotherapy without additional photosensitizers, as it did not reduce keratinocyte differentiation markers or increase photo-oxidative damage, unlike treatment with IL-4 or UVA1/blue light.

This review discusses the role of extracellular vesicles from specific skin cells in wound healing, emphasizing their potential in regenerative medicine and reporting no new experimental results.

This study suggests that high proliferative activity and peripheral invasion are key indicators of malignancy in canine sebaceous gland tumours. It also reports a higher incidence of circumanal gland and testicular tumours, indicating a possible androgen-related pathway in tumour development.

In this narrative review, researchers outlined the role of T cells in the autoimmune pathogenesis of alopecia areata and highlighted ongoing research into therapeutic pathways, beyond current JAK inhibitors, aimed at developing new treatments for the disease.

This study found that alopecia areata patients who responded poorly to topical immunotherapy had impaired peripheral blood mononuclear cell responses to T-cell stimulants.

This study found that γδ T cells play a role in regulating stromal behavior, influencing the composition and vascularity of fibrotic tissues during the foreign body response.

In this study, researchers used a mouse model to identify an adipocyte-to-fibroblast conversion pathway that promotes mast-cell recruitment and dermal fibrosis in atopic dermatitis, suggesting a potential therapeutic approach to block this process and reduce inflammation and fibrosis.

This study introduces stem cell activity as a key factor influencing the effects of IFN-γ and TGF-β1 on autoimmune disease dynamics, showing that varying cytokine levels can modulate stem cell activity and immune privilege, impacting tissue regeneration and disease flares.

This study synthesizes knowledge of how dendritic cell signals, epithelial integrins, and fibroblast activity converge on TGF-β1 to maintain or disrupt skin healing, contrasting normal and fibrotic scar formation and suggesting possible integrin and immune-targeted treatments for skin fibrosis.

This study suggests that phloroglucinol may enhance anagen signaling and reduce oxidative stress-induced damage in human dermal papilla cells, offering a potential therapy for hair loss.

This review discusses the potential link between contact allergy and frontal fibrosing alopecia, noting the presence of implicated allergens in current literature, but reports no new clinical findings.

This study examined the molecular communication in psoriasis cells, highlighting unique immune cell interactions and identifying new features of the hair follicle cell-psoriasis axis. It suggests the potential for targeted therapies at the single-cell level to improve psoriasis treatment.

In this study, the researchers found that deleting ceramide synthase 4 in the skin's epidermis alters stem cell differentiation, disrupting hair follicle structure and barrier function, potentially leading to immune responses similar to atopic dermatitis.

This review discusses the clinical applications of adipose tissue-derived stem cells in dermatology and plastic surgery, highlighting their potential benefits but also noting existing limitations and concerns.

T cells and bacteria in the gut and skin help maintain health and protect against disease.

This study found that CD1a-restricted CD4+ T cells responsive to lysyl-phosphatidylglycerol were more frequent in the blood of atopic dermatitis patients, suggesting a potential role in the disease's Th2-mediated pathology.

The researchers reported that DHT may reduce the inflammatory responses induced by C. acnes in androgen-sensitive human sebocyte cells, suggesting a potential link between androgens and infection in sebaceous disorders.

In this study, researchers found that patients with alopecia areata who had nail involvement or a history of autoimmune disease showed significantly higher red cell distribution width levels.

This study found that fisetin, a dietary flavonoid, significantly improved psoriasiform skin lesions in mice by promoting cell differentiation, inhibiting proliferation, and modulating inflammatory responses.

This study reveals that hair follicles in mice and humans recruit epidermal Langerhans cells during skin inflammation via specific chemokine signaling pathways.

Glycerin in hand cream can cause allergic skin reactions.

This case report details a patient who developed multiple skin cancers within one year of receiving an allogeneic haematopoietic cell transplant for chronic lymphocytic leukaemia.

This report highlights the usefulness of specific diagnostic procedures, including penile/preputial cytology and transabdominal ultrasonography, in diagnosing cryptorchidism and Sertoli cell tumors in dogs with generalized skin conditions.

This review examines the role of regulatory T cells in skin immune disorders, highlighting their unique functions in conditions like scleroderma, alopecia areata, and psoriasis, without reporting new clinical results.

This study found that T-regulatory cells, specifically the FOXP3 CD39 subset, were significantly reduced in both circulation and hair follicles of alopecia areata patients compared to healthy subjects, suggesting potential therapeutic targets.

This review highlights advances in understanding inflammatory memory in epidermal stem cells, focusing on their capacity to remember prior inflammatory responses and respond more quickly to future stimuli, potentially aiding strategies against skin-related diseases.

This review discusses the heterogeneity of Tregs in normal and tumor environments, emphasizing the complexity of targeting tumor-resident Tregs while maintaining systemic immune tolerance, but reports no new findings.

This review discusses the use of Dermal Papilla cells as in vitro models for studying hair growth modulators, emphasizing their role in aiding the development of new hair treatments, but reports no new clinical results.

This study found that patients with alopecia areata had higher levels of Th17 cells and lower levels of regulatory T cells compared to healthy controls, suggesting an immune imbalance in these patients.
