In this study, researchers found that CD4 is expressed on murine K5⁺ keratinocytes, and its expression is crucial for maintaining epidermal stem cell balance and wound repair capacity, particularly during aging.

In this study, Caplan et al. found that treatment with human Tregs expanded from umbilical cord blood may modulate immune responses and improve outcomes in a rodent model of traumatic brain injury.

Enhancing regulatory T cells may help treat autoimmune diseases like alopecia areata.

This study reviews current evidence on the role of ILC3s in the skin, highlighting their potential involvement in responding to microbiome changes such as those associated with acne and suggesting gaps in understanding their mechanisms.

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.

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.

Scientists turned rat thymus cells into stem cells that can help repair skin and hair.

In a mouse model of chemotherapy-induced alopecia, this study found that enhancing ETV2 expression improved angiogenesis and hair regrowth following 5-fluorouracil treatment.

In this study, CD4+ non-haematopoietic, skin-resident stem cell-like populations were identified in both murine and human epidermis, suggesting they may serve as potential basal cell carcinoma precursors.

In this study, inactivating the TAF4 subunit of transcription factor TFIID in mouse epidermis disrupted gene expression linked to skin and hair function, and increased tumor risk.

Ritlecitinib effectively treats alopecia areata and is well-tolerated.

This study found that VEGF stimulates the proliferation of human hair follicle dermal papilla cells via the VEGFR-2/ERK pathway, without involving p38, JNK, or AKT signaling.

This study found that ILC1-like cells can induce alopecia areata symptoms in both ex vivo human hair follicles and in vivo mouse models, challenging the view that alopecia areata is solely CD8+ T cell-driven.

The researchers reported that iPSCs derived from Sendai virus reprogrammed blood cells can mature into functional keratinocytes for up to 60 days, potentially offering new approaches for DEB treatment.

The study reports that the AVET system showed higher efficiency in transfecting cultured human keratinocytes compared to SuperFect and PrimeFector, with AVET reaching levels of enzyme activity similar to normal cells in keratinocytes from lamellar ichthyosis patients.

In this case study, a rare viral infection called trichodysplasia spinulosa was diagnosed in a 10-year-old girl post-kidney transplant; she was treated successfully with reduced immunosuppression alongside leflunomide and valganciclovir, though the efficacy of valganciclovir remains uncertain.

Researchers demonstrated that a new vaccine platform using antigen-loaded hydrogels enhanced humoral immune responses in mice, producing stronger antigen-specific antibody levels compared to the conventional adjuvant Alum, and offering promising protective capabilities against influenza virus.

In this study, Trf1 genetic deletion in mice, including those with cancer-prone mutations, was shown to not affect overall viability and cause only mild effects, while being necessary for tumor formation, suggesting a potential therapeutic window for Trf1 as an anti-cancer target.

This study found a specific T cell receptor that may be key in carbamazepine-induced Stevens-Johnson syndrome and toxic epidermal necrolysis, suggesting potential therapeutic targets.

In this case study, donor lymphocyte infusions effectively eradicated measurable residual disease in a patient with relapsed acute myeloid leukemia after hematopoietic cell transplantation, while side effects included the development of vitiligo and alopecia areata, likely due to chronic graft-versus-host disease.

Contact immunotherapy can change immune responses in alopecia areata, suggesting new treatment targets.

This study found that CI-1033 caused skin lesions in rats that resemble effects seen in humans receiving EGF receptor inhibitors, suggesting this animal model can help explore the mechanisms behind this cutaneous toxicity.

In this study, researchers successfully generated functional and long-lived melanocytes from human embryonic stem cells, demonstrating their biocompatibility and high engraftability in mice, which may aid in developing treatments for pigmentary skin disorders.

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 study found that recombinant human leukocyte interferon alfa-2a achieved a 64% overall antitumor response rate in patients with early and advanced cutaneous T cell lymphoma and was generally well-tolerated.

In this study, neoadjuvant treatment with durvalumab combined with albumin-bound paclitaxel and carboplatin in patients with driver gene-negative stage III NSCLC showed a 65% objective response rate and was associated with high pathological response rates and improved immune function, with most adverse events being mild.

This study found that epithelial cells in the skin of live mice regulate the density and spatial organization of immune cells, which actively maintain their position despite constant cell turnover.

VYN201 shows promise as a safe and effective treatment for non-segmental vitiligo.

This review highlights Ritlecitinib as a promising new oral treatment for Alopecia Areata, emphasizing its targeted action and potential efficacy, especially in adults and adolescents, though it notes the need for further real-world effectiveness and long-term safety studies.

This study found that oral administration of Flammulina velutipes polysaccharide reduced tumor volume and improved survival in mice by modulating macrophage polarization and enhancing antitumor immune responses.
