This review outlines pregnancy risks in systemic lupus erythematosus and emphasizes that active lupus nephritis at conception increases the risk of flares and poor obstetric outcomes; it reports no new clinical findings.

This study suggests that Notch1 acts as a key signal in skin epithelium, promoting immune cell recruitment and aiding in normal skin repair after damage.

The document concludes that rapid identification, isolation, and strict infection control are crucial to manage SARS outbreaks.

This review discusses the roles of αβ and γδ T cells in skin health and disease and reports no new clinical results; the authors highlight potential therapeutic developments.

The TGF-β family helps control how cells change and move, affecting skin, hair, and organ development.

This study identified changes in transcription factor gene expression across various signaling pathways during inner ear hair cell regeneration in birds, revealing patterns and potential new pathways for future investigation.

This review examines how mesenchymal stem cells and their derivatives may enhance skin regeneration and rejuvenation, but it reports no new clinical results; the authors suggest iPSC-derived MSCs hold promise for future therapies.

This review identifies shared interferon gamma-driven immune pathways in vitiligo and alopecia areata, revealing potential targets for new treatments, but reports no clinical results.

This review summarizes existing knowledge on the role of FOXN1 as a key regulator of thymic epithelial cell lineage and function, reporting no new experimental results.

This study demonstrated that a c-Kit-CreER-driven mouse model confirms melanocyte stem cells as a genuine source of melanoma, paralleling human melanoma in heterogeneity and gene signatures.

In this study, researchers found that electrospun membranes with aligned surface topography advanced the immune response towards an adaptive stage and highlighted the role of T cells in hair follicle regeneration in mice, showcasing the intricate interactions between immune and skin cells.

This article reviews the role of perifollicular regulatory T cells in maintaining hair follicle integrity in the context of hidradenitis suppurativa and calls attention to inflammatory mechanisms without reporting new clinical results.

This review suggests that isotretinoin's effects on severe acne and various cancers may result from apoptosis, which might also explain its adverse effects through genetic variability.

Fibroblasts can be turned into melanocytes for potential skin treatments.

In this study, blocking the CXCR3 receptor in mice prevented the development of alopecia areata by inhibiting the accumulation of specific T cells in the skin, suggesting a potential therapeutic approach for humans.

This study found that biallelic mutations in the TTC7A gene affect lymphocyte and gut epithelial cell function, thereby contributing to the development of inflammatory bowel disease in patients.

This study reports the successful generation of inducible pluripotent stem cells from mesenchymal stem cells derived from human hair follicles, marking a novel method of reprogramming these cells.

This review examines testosterone's role in male health and aging but reports no new clinical results; the authors highlight the need for further research on optimal testosterone levels to prevent age-related conditions.

This study suggests that CD8+ cytotoxic T lymphocytes play a crucial role in the development of alopecia areata, based on observations in rodent models that mimic human autoimmune disease.

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.

Graft-versus-host disease is a complication where donor immune cells attack the recipient's body, often affecting the skin, liver, and gastrointestinal tract.

This study found that H-Ras activation in aged mouse skin leads to increased dysplasia and progression to in situ squamous cell carcinoma, highlighting an age-linked connection between immune changes, senescence, and cancer risk.

This study demonstrates that canonical Wnt signaling is crucial for maintaining thymic epithelial microenvironments in postnatal thymus, possibly by affecting TEC progenitor cells.

This review discusses the relationship between aging, chronic inflammation, and immunosuppression, suggesting that these interconnected processes may contribute to tumorigenesis and premature aging, but reports no new experimental results.

This study found that WNT10A is significantly upregulated in human esophageal squamous cell carcinoma and is associated with enhanced tumor cell migration, invasion, and poor survival.

This article discusses the complex role of TGFβ in cancer progression, highlighting its dual function as both a tumor suppressor in early stages and a promoter in later stages, without reporting new results.

This review discusses the potential of stem cell secretome in regenerative medicine and suggests that its paracrine effects, rather than direct cell replacement, may drive therapeutic benefits.

In this study, researchers observed that hyperandrogenic PCOS patients exhibited distinct miRNA and TGFβ signaling gene expression patterns in granulosa cells, suggesting these factors may play a role in PCOS pathogenesis.
