In this study, researchers discovered that the HrasG12V oncogenic mutation in murine skin epithelial cells initially promotes progenitor cell renewal but later leads to a balanced differentiation, stabilizing clone growth.

This study found that Epstein-Barr virus infection upregulated a truncated variant of human basic hair keratin 1 (hHb1-ΔN) in gastric carcinoma cell lines, suggesting a possible link to carcinoma differentiation.

In this study, researchers documented the immunohistochemical distribution of CD34 in basal cell carcinoma and found distinct patterns of CD34 expression, with variations in CD34 positivity between different areas of BCC tumor stroma and adjacent skin regions.

This study shows that inhibiting anti-apoptotic proteins BCL-W and BCL-XL can specifically induce apoptosis in senescent cells, suggesting a potential strategy for treating age-related pathologies.

The research found that hair follicle–derived cytokines, particularly IL-15 and IL-7, regulate skin-resident memory T cells and their role in both immune homeostasis and lymphoma in the skin.

This letter discusses three plasmacytoid dendritic cell-related parameters that may help differentiate lupus alopecia from lichen planopilaris, but it reports no new study results.

In this study, Mononuclear Cells provided site-specific protection against chemotherapy-induced alopecia in rats treated with Ara-C, but not with CTX or VP-16, while PRP showed no protective effect.

This study found that the novel anti-HER2 antibody RC48 demonstrated promising activity and manageable safety in patients with HER2-overexpressing, advanced gastric or gastroesophageal junction cancer after at least two prior chemotherapy lines.

In this study, treatment with IL-2C to expand Tregs effectively halted hair loss progression in a murine model of alopecia areata.

This study reports that a clinical prognostic model based on immune-related genes improved survival prediction for patients with clear cell renal cell carcinoma, also identifying potential drugs targeting the gene DOCK8.

This study found that RANKL signaling enhances CD8+ T cell-mediated anti-viral immunity during herpes simplex virus infection by preventing apoptosis of Langerhans cells, suggesting potential therapeutic applications.

In this study, researchers reported that IL-17C plays a key pro-inflammatory role in human skin diseases and may be a promising therapeutic target for inflammatory skin conditions.

A specific type of immune cell plays a key role in causing alopecia areata and could be a target for treatment.

In this study, full-size KRT81 was expressed in both normal breast epithelial and breast cancer cells, and contributed to the migration and invasion abilities of breast cancer cells.

This study found that Merkel cell carcinoma recurrence risk peaks within the first two years after diagnosis and varies significantly by stage, with immune suppression, age, and male sex also influencing risk.

In this study, researchers found that CD4 T cells from the skin draining lymph nodes of mice with alopecia areata can transfer the disease to recipient mice, highlighting the key role of these cells and their interaction with CD8 T cells in the disease's development.

This review summarizes current evidence on how beta-human papillomavirus and Merkel cell polyomavirus may contribute to the development of nonmelanoma and Merkel cell skin carcinomas, respectively, but it reports no new clinical findings.

This study reported that the anti-γc antibody hC2 restored hair follicle homeostasis and suppressed hair loss in an AA-like mouse model by inhibiting autoreactive T-cell activity, suggesting that hC2 may offer a safer and more effective treatment for alopecia areata compared to current Jak inhibitors.

This study found that the CD301b-expressing subpopulation of macrophages plays a crucial role in promoting reparative processes during the mid-stage of skin wound healing in a mouse model.

This study found that CD34- melanocyte stem cells regenerated pigmentation more efficiently, while CD34+ cells showed potential for neuron myelination, suggesting different therapeutic applications for each population.

This study found that gene expression of CD70 and CD27 was higher in alopecia areata lesions and correlated with increased disease severity and activity.

This study identified a monoclonal antibody, HKN-2, that recognizes specific cells in human skin and may indicate a common antigenic determinant between hair and other skin epithelial tissues.

This case study reports an unusual presentation of primary cutaneous diffuse large B-cell lymphoma–leg type occurring on the upper lip of an 81-year-old woman, highlighting the need for timely recognition of atypical manifestations.

This study observed that expanding regulatory T cells in the skin of mice with alopecia areata did not reverse the condition, indicating that additional immunotherapy may be necessary.

This study found that ablating cyclin D3 in a Ras-dependent skin carcinogenesis model increased apoptosis in hair follicles, reducing papilloma development but potentially facilitating malignant progression when CDK6 is overexpressed.

This study found that NKIRAS2 expression affects skin tumor suppression and HRAS-driven transformation in mice, indicating its role in carcinogenesis depends on expression level and cellular context.

The authors concluded that antibodies against tyrosinase and gp100 may be effective in diagnosing melanoma, including challenging variants like amelanotic and desmoplastic types, when appropriate antigen retrieval techniques are used.
