In this study, researchers developed a mouse model of scarring alopecia and observed significant reductions in CD200R expression in affected skin, potentially linking this signaling pathway to immune attacks on hair follicles and suggesting new treatment targets for scarring hair loss.

This study suggests that the presence and arrangement of plasmacytoid dendritic cells can help distinguish chronic cutaneous lupus erythematosus from other types of scarring alopecia.

This study demonstrated that transcutaneous vaccination via cyanoacrylate skin surface stripping effectively induced both CD4 and CD8 T cell responses in humans, offering a promising alternative to intramuscular injection.

A new test helps find drugs to treat head and neck cancer by targeting c-Rel.

This study found that actively targeted AN2728-loaded nanocarriers reduced inflammation and improved skin condition in a mouse model of psoriasiform inflammation compared to free drug and non-targeted nanoparticles.

This study found that CD34 is necessary for TPA-induced activation of hair follicle stem cells and tumor formation in mice, with CD34 knockout mice showing delayed and reduced tumor development compared to wild-types.

This study identified a high proportion of dual TCR Treg cells in both lymphoid and non-lymphoid tissues of mice, revealing their tissue specificity, TCR repertoire characteristics, and functional phenotypes.

Expanding regulatory T cells may help treat alopecia areata by reducing harmful immune cells.

This study identified CD28, GZMB, and CD1C as key immune regulators in alopecia areata, highlighting CD28 as a potential therapeutic target with a promising safety profile, using a proteome-anchored multi-omics approach to uncover actionable targets for this autoimmune hair-loss disorder.

This study found that plasmacytoid dendritic cells may initiate alopecia areata in mice by overexpressing interferon-alpha.

This study found that immunohistochemistry can effectively distinguish between tricholemmoma and basal cell carcinoma, with BerEP4 and CD34 serving as key differentiators.

In a murine model of alopecia areata, this study observed that the IL-2 fusion protein HCW9302 helped prevent disease development by expanding regulatory T cells and reducing disease-causing effector T cell infiltrates, suggesting potential for using IL-2 fusion proteins in alopecia areata treatment.

This study found that Rab27a and Rab27b play opposite roles in hair growth, with Rab27a knockdown suppressing and Rab27b knockdown promoting hair growth in models.

This study examined dermoscopic features in African-American women with different types of alopecia and found that a perifollicular pink blush, potentially indicating inflammation, was common, particularly resolved with anti-inflammatory treatment, suggesting dermoscopy could aid in management.

CD44 variant changes start alopecia areata, but don't maintain it.

This study found that carbonic anhydrase II was significantly upregulated in human keratinocytes when treated with toll-like receptor 3 agonist and Th2 cytokines, suggesting its potential role in inflammatory skin conditions.

This study found that a single application of TCDD on the skin of hairless mice altered epidermal differentiation, changing keratin expression patterns similarly to a known tumor promoter.

This study reported that CCT oligodeoxynucleotide induced patchy hair loss in male mice with specific genetic traits, suggesting gender and genetic preferences in immune response.

This study found that the protein CCN2 in dermal papilla cells is a physiologically relevant suppressor of hair follicle formation by destabilizing β-catenin, which may help maintain stem cell quiescence.

This research suggests that hair follicle-derived cytokines IL-7 and IL-15 are crucial for maintaining resident memory T cells in the skin, which may be relevant for diseases like cutaneous T cell lymphoma.

This study identified altered mRNA and lncRNA profiles in NS scalp tissues, highlighting CDKN2AIP as a downregulated gene involved in a ceRNA network.

This study reports that miR-22 promotes cancer progression and metastasis by maintaining Wnt/β-catenin signaling and cancer stem cell function.

This study found that p21 is much more highly expressed in normal melanocytes compared to melanoma cells, suggesting a potential target for preventing melanoma progression through cell cycle repair processes.

This study found that DC-HIL+ myeloid derived suppressor cells are increased in the blood and skin of patients with cutaneous lupus erythematosus and show immunosuppressive properties.

Certain CD8+ T cells attack hair follicles in alopecia areata, suggesting they could be targeted for treatment.

This study suggests that monitoring CD8+ TEMRA cells in patients with rapidly progressive alopecia areata treated with intravenous corticosteroids could help predict therapeutic outcomes.

Versican in dermal papilla cells is crucial for healthy hair growth.

This study identified CD28 as a potential drug target in treating alopecia areata by linking immune signaling pathways to local inflammation, highlighting belatacept as a promising treatment option due to minimal adverse effects and providing insights into autoimmune target discovery.
