This study found that P311 triggers transdifferentiation of epidermal stem cells into myofibroblast-like cells via TGFβ1/Smad signaling during wound healing.

This review discusses recent advancements in therapies for ichthyosis, highlighting promising prospects in protein replacement and gene therapy, but it reports no new clinical results.

This study found that certain T cell-associated genes were upregulated in dogs with Vogt-Koyanagi-Harada syndrome and vitiligo, suggesting a shared immunopathogenesis with humans.

This review discusses the potential of biologics for treating various skin disorders, highlighting positive outcomes in conditions like pityriasis rubra pilaris and lupus, while noting mixed efficacy in others like alopecia areata; it reports no new clinical results.

This study found that soluble CD83 (sCD83) accelerated chronic and hard-to-heal wound healing and improved inflammatory and pro-resolving cytokine profiles, suggesting potential for therapeutic use.

In this study, subcutaneous injection of bone marrow mesenchymal stem cells in burned rats significantly improved wound healing by reducing inflammation, scar formation, and wound size, and restoring normal skin structures.

This study found that targeting IL-6, IL-1, and CCR6 signaling pathways may effectively reduce irradiation-induced alopecia and dermatitis in radiotherapy patients.

This review reports no new results but highlights the secretory function of keratinocytes, focusing on how various secretions, notably growth factors, impact stem cell differentiation into keratinocytes.

This review discusses the complex role of immune disturbances and the JAK-STAT pathway in alopecia areata, noting the success of JAK inhibitors in treatment, while highlighting ongoing debates and challenges in targeting other pathways like IL-17 and TNF-α.

This study found that patients with alopecia areata and their healthy family members had elevated levels of Th1- and Th17-related cytokines, suggesting a genetic link in cytokine dysregulation.

This study found that astilbin downregulates effector CD4+ T cell activities through the CYP1B1/ROS/PPARγ pathway, suggesting its potential use in treating inflammation.

This review outlines current treatments for folliculitis decalvans and dissecting cellulitis of the scalp, noting conventional therapies' limitations and promising but limited results from targeted biologic agents.

This review synthesizes current evidence on therapies for dissecting cellulitis of the scalp, noting that biologics show promise for treatment-resistant cases, though systemic retinoids remain the first-line therapy.

In this study, PA-011, a traditional Chinese medicine extract, was shown to improve hair growth in alopecia areata model mice by reducing skin inflammation and altering skin microbiota, indicating its potential therapeutic role for this condition.

This study found that CGF may be effective in reducing inflammation and improving skin conditions in psoriasis, particularly in patients resistant to other treatments.

This literature review explores the role of biomarkers in personalized medicine for various dermatological conditions like Hidradenitis Suppurativa, Psoriasis, and Atopic Dermatitis, highlighting how they guide targeted therapies and the limitations of current markers in specificity, as reported by the authors.

Secukinumab reduces immune activity in hidradenitis suppurativa skin.

This case report describes a patient who developed multiple skin reactions, including eczematous lesions and alopecia areata, during adalimumab treatment, but found no improvement in pustulosis palmoplantaris with different biologics.

This study found that 17β-estradiol inhibited RANTES production in human keratinocytes by suppressing nuclear factor κB activity, suggesting a potential mechanism for 17β-estradiol's modulation of psoriasis-related inflammation.

This research notes that biologics and small molecules are effective for treating nail psoriasis and alopecia areata, albeit with precautions for adverse events, but no clinical trials have been published for their use in treating nail lichen planus and atopic dermatitis.

This review outlines the various adverse reactions to biologic therapies in Allergy/Immunology, emphasizing the clinical and management challenges due to overlapping reaction phenotypes and the need for more refined diagnostic and management strategies.

In this study, topical MR blockade improved delayed wound healing in glucocorticoid-pretreated mice by promoting anti-inflammatory macrophages and enhancing angiogenesis.

This paper discusses the role of epidermal growth factor receptor blockade in altering skin and hair growth, highlighting hair growth stimulation as a potential side effect of cancer therapy; it reports no new experimental results.

This study reported that new drugs, despite lower specificity compared to certain immunobiological therapies, are effective across various challenging dermatological diseases, such as psoriasis, psoriatic arthritis, atopic dermatitis, alopecia areata, and vitiligo.

The document concludes that new treatments for skin conditions are complex but effective, including spironolactone for female hair loss and propranolol for infantile hemangiomas.
