This study describes the expression patterns of type I inner root sheath keratin proteins K25–K28 in human hair follicles, highlighting their distinct distribution within different layers.

In this study, activation of Tgr5 was found to improve alopecia areata and bone microstructure in mice by down-regulating the JAK1-STAT3 signaling pathway.

This study found that systemic treatment with DS77754007, a KLK5 inhibitor, improved skin symptoms in a mouse model of Netherton Syndrome more effectively than certain antibody treatments, suggesting KLK5 inhibition as a promising therapeutic approach for this condition.

JAK inhibitors show promise for treating alopecia areata, but more research is needed.

This source describes a previous case report that combined anthralin and calcipotriene to treat alopecia areata, showing promising results, but highlights that further research is needed to understand the mechanisms and potential benefits of this combination therapy.

This study observed that hereditary factors were associated with acne duration but not severity, and found a potential role of CYP450 1A1 polymorphisms in acne pathogenesis.

In this study, nearly 5% of anti-TNF-treated patients with IBD developed psoriasiform skin lesions, with smoking identified as a main risk factor, and ustekinumab proved highly effective in severe cases.

In this research, authors found that skin-resident ILCs regulate sebaceous gland function and microbial balance, emphasizing an immune-epithelia system that supports host-microbe symbiosis.

This review explores recent findings on regulatory T cells, focusing on their unique functions in non-lymphoid tissues and new mechanisms of action, but presents no original clinical results.

The researchers reported that dsRNA from damaged skin activates TLR3, promoting hair follicle regeneration, while TLR3-deficient animals fail to initiate this process, suggesting potential therapeutic approaches for hair neogenesis.

This study found that pro-inflammatory cytokines and apoptotic mechanisms, specifically involving granzyme B and Fas pathways, are associated with chronic alopecia areata, indicating their potential role in the disease's persistence.

This study highlights the evolving understanding of acne's pathophysiology and suggests that targeting pro-inflammatory cytokines such as IL-1β, IL-17, IL-23, and TNFα with biological antibodies may offer new treatment strategies for severe acne and its scars.

This review summarizes 15 years of clinical and experimental research advancements in hidradenitis suppurativa, highlighting its recognition as a uniquely healable inflammatory skin disease but reports no new clinical results.

This study observed that in aged mouse skin, there was an increase in IL-17-expressing T helper cells, γδ T cells, and innate lymphoid cells, and blocking IL-17 signaling reduced skin inflammation and delayed age-related changes, suggesting it as a potential target to mitigate skin aging.

This study found that Schistosoma mansoni cercariae stimulate epidermal keratinocytes in mice, initiating pro-inflammatory responses and barrier repair mechanisms akin to those in wound healing.

This study suggests that targeting specific immune pathways, such as IL-12/23 and Th2 cytokines, may offer new treatment options for alopecia areata, a T-cell-mediated disease without current mechanism-specific therapies.

This review discusses the significance of IL-1 family cytokines in skin inflammation and pathology, emphasizing their interactions with microbes and potential therapeutic applications, but reports no new clinical results.

This study investigated the role of NLRP3 inflammasomes in alopecia areata and found that outer root sheath cells may contribute to inflammation by increasing IL-1β and HMGB1 secretion when stimulated with double-stranded RNA.

This review explores the role of neutrophil recruitment in the inflammation seen in hidradenitis suppurativa and emphasizes potential therapeutic targets within these pathways, but it reports no new clinical results.

This study found that intramuscular anti-IFN-γ significantly stabilized and promoted hair regrowth in alopecia areata patients with patchy, progressive hair loss, whereas those with total baldness showed more limited improvement.

This review examines various immunomodulatory therapies for cutaneous lymphoma and notes that they are most effective in the disease's early stages.

This study found that higher levels of DHA from omega-3 fatty acids delayed inflammation resolution and impaired wound healing quality in both transgenic mice and wild-type mice supplemented with DHA.

This study found that the plant Clausena anisata exhibited promising antimicrobial, antioxidant, and anti-inflammatory activities against acne-causing bacteria and inflammation, suggesting its potential as a candidate for further anti-acne treatment research.

This study found that glycyrrhetinic acid, derived from licorice, may help alleviate acne symptoms by regulating lipid synthesis and inflammatory responses through multiple pathways, as observed in both in vitro and in vivo settings.

This study found that while all hair removal techniques increased axillary erythema and skin dryness, shaving caused less erythema but more dryness than plucking or waxing, without affecting post-inflammatory hyperpigmentation or other skin properties.

This case report describes a 40-year-old man whose vitiligo and psoriasis responded favorably to ixekizumab after experiencing vitiligo onset and psoriasis relapse during adalimumab treatment.

This case report describes a 21-year-old woman with progressive alopecia areata who experienced hair regrowth while treated with tocilizumab for posterior uveitis, suggesting the potential for this drug to affect hair loss and regrowth by disrupting interleukin-6 signaling.

This study found that higher serum IL-21 levels may serve as a promising diagnostic and prognostic marker for alopecia areata, strongly correlating with disease activity.

In this study, yeast fermentation of Platycladus orientalis leaves was shown to enhance hair growth-promoting properties by affecting cell cycle phases in human dermal papilla cells, increasing growth factor VEGF, reducing inflammatory factor TGF-β1, and altering the expression of Wnt/β-catenin pathway-related genes.

This review examines the interconnected processes of atopic dermatitis and alopecia areata, highlighting shared immune imbalances, genetic factors, and microbiome influences, while analyzing current and emerging treatments and identifying gaps in understanding these overlapping conditions.
