This study found that the activity of CD73, an enzyme expressed in the hair follicle epithelium, may regulate human hair growth by modulating adenosine production.

This study found that stimulating olfactory receptor OR2AT4 in human hair follicles with Sandalore® may slow catagen development and reduce keratinocyte apoptosis, suggesting potential implications for hair growth management.

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.

This article discusses the histologic features of psoriasis, including psoriasiform epidermal hyperplasia and neutrophilic involvement, but reports no new clinical findings.

This review noted that alopecia areata is an autoimmune disease impacting hair follicles and offered insights into its complex pathogenesis involving immune responses, while highlighting ongoing research into new treatments such as Janus kinase inhibitors and other immunomodulatory drugs.

In this study, three patients with extensive alopecia areata showed varying degrees of hair regrowth after 20 weeks of treatment with ustekinumab, a cytokine-targeting therapy.

This review discusses the cutaneous manifestations associated with HIV infection, highlighting that these skin conditions often present atypically and are more severe compared to those in non-HIV-infected individuals; it reports no new clinical findings.

This study found that patients with alopecia areata had significant systemic inflammation and vitamin D deficiency, with both conditions more pronounced as disease severity increased.

This study found that the interaction between heat shock protein 90 and lamin A/C is crucial for the growth, migration, and self-aggregation of dermal papilla cells, suggesting a potential role in alopecia areata mechanisms.

This study suggests that dietary vitamin A may influence alopecia development and progression, but the mechanisms remain unclear, highlighting the interplay between genetics and nutrition in these hair loss conditions.

ALDOA levels drop in hair cells during hair loss.

JAK inhibitors effectively regrow hair in alopecia areata but hair loss often returns after stopping treatment.

In this mini-review, recent insights suggest a possible role of type-2-related immunity in diseases like alopecia areata, vitiligo, and localized scleroderma, though whether this immune response benefits or worsens these conditions remains unclear.

This study found a significant association between alopecia areata and low serum ferritin levels, suggesting that assessing and correcting iron stores might improve alopecia areata management.

This review evaluates the role of the nuclear receptor PPAR- in skin diseases, highlighting its regulation of inflammation, lipid metabolism, and immune response, and suggests that PPAR-agonists could be promising therapies for conditions like psoriasis and atopic dermatitis.

This report highlights a case of a 35-year-old man developing alopecia universalis following alemtuzumab treatment for multiple sclerosis, suggesting potential links between this medication and drug-induced alopecia areata, though the genetic overlap of the conditions may also play a role.

This review examines current treatments for alopecia areata, noting that topical corticosteroids are commonly used first in children, while more advanced cases may require systemic therapies to modulate the immune system; it reports no new clinical results.

This study observed that photobiomodulation therapy may contribute to hair growth stability or improvement in individuals with darker skin types, without reported adverse events, though its findings are limited by a small sample size.

This study reports a case of a 28-year-old woman diagnosed with metastatic breast cancer through bone marrow analysis using flow cytometry and immunohistochemistry, highlighting the potential of flow cytometry as a valuable diagnostic tool for detecting solid tumors.

Hirsute women with ovarian-sourced hirsutism are more likely to have irregular periods, with higher BMI and altered hormone ratios.

Alopecia linked to higher anxiety and personality disorders.

This study found that elevated serum cortisol levels and other immunological changes are significantly involved in the active phases of psoriasis eruptions.

This article reviews the role of androgen in male pattern hair loss and its impact on hair follicle miniaturization, but it does not present new research findings.

Auto-portraits help evaluate scalp hair.

This article reviews the clinical presentation and histopathologic features of alopecia areata and proposes a hypothesis for its development, but it reports no new clinical results.

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

This study summarizes how the IL-23/IL-17 axis contributes to inflammatory skin diseases like psoriasis and highlights that biologics targeting this pathway, including monoclonal antibodies against IL-23 and IL-17, have shown efficacy in clinical trials for these conditions.

In this study, rheumatoid arthritis patients showed no changes in the number of circulating follicular helper T cells, but these cells had increased CD200 expression, implicating them in disease pathogenesis and suggesting CD200/CD200R as a potential therapeutic target.

This review discusses the use of contact sensitizers for topical immunotherapy in dermatological conditions such as alopecia areata and viral warts, but it reports no new clinical findings.
