This study identified CD201+ fibroblast progenitors in mouse skin that regulate wound healing through differentiation into specialized cell types, with retinoic acid and hypoxia influencing this process.

Certain immune system genes are linked to a higher risk of psoriasis and psoriatic arthritis, while others may offer protection.

This study suggests that rather than inhibiting IL-15, selectively stimulating IL-15Ra-mediated signaling could be beneficial for managing alopecia areata and possibly other inflammatory hair loss conditions, as IL-15 promoted hair growth and maintained immune privilege in human hair follicles.

Calretinin identifies the companion cell layer in human hair follicles.

This study found that in psoriasis patients, the K17 protein probably functions as an autoantigen, with the HLA-Cw*06:02 risk genotype strongly linked to the T cell response size.

In this study, researchers found that overexpression of CRABP2 enhanced the proliferation of dermal papilla cells in Hu sheep through activation of the Wnt/β-catenin pathway, even when the pathway was inhibited.

This article discusses the expression and potential new roles of innate immunity genes in CD49f(+) /CD34(+) hair follicle stem cells, but reports no new experimental results.

This study found that an E-cadherin mutant preserved normal cadherin levels and prevented inflammation and lethality in mouse skin lacking p120, highlighting p120's role in regulating cadherin-mediated cell adhesion and inflammation.

This study suggests that basonuclin in keratinocytes is likely a regulatory molecule linked to maintaining proliferative capacity and preventing terminal differentiation rather than a cell cycle marker.

This review explores the role of Tregs in autoimmune skin diseases, transplantation, and skin cancer, and discusses Tregs-based therapies' potential for treating autoimmunity without reporting new experimental results.

This study found that human fetal CD133+ progenitor cells and their conditioned medium accelerated wound healing and promoted angiogenesis in a mouse model of ischemic diabetic ulcers through paracrine mechanisms involving Wnt signaling.

This study identified a radio-resistant population of Krt15+ stem cells in the mouse small intestine that can initiate tumors, suggesting potential targets for colon cancer therapy.

This study observed that dalpiciclib is associated with fewer adverse events like diarrhea and hepatotoxicity compared to other CDK4/6 inhibitors, potentially offering better patient-perceived safety and quality of life.

In this study, researchers observed elevated levels of epidermal γδ T cells, keratinocytes, and an upregulation of the BST2 gene among immune cells in C3H/HeJ mice with alopecia areata, suggesting a potential role in disease pathogenesis.

This study found that deleting Stim1 and Stim2 in mature T regulatory cells disrupts Ca 2+ signaling, preventing their differentiation and leading to severe autoimmune disorders in mice.

This study suggests that macrophages, especially CD206+ subsets, play a key role in hair growth induced by squaric acid dibutyl ester, a therapy used for alopecia areata.

This study found that bone marrow-derived epithelial cells were abundantly recruited to some skin tumors in mice, indicating a systemic contribution to cutaneous neoplasms.

In this study, researchers found that hair follicle stem cells activate an immune-modulatory program during wound healing, promoting Treg cell expansion and aiding skin repair, while deleting certain immune components impaired healing and increased inflammation in a mouse model.

Cedrol promotes hair growth better than baricitinib by regulating immune cells.

D-chiral biomaterial scaffolds enhance tissue and hair regeneration by activating the body's immune system.

This study suggests that macrophages, particularly CD206⁺ macrophages, play a crucial role in squaric acid dibutylester-induced hair growth in alopecia areata treatment.

Highly active but fewer CD14+CD16- monocytes are found in Alopecia Areata patients, regardless of severity.

A specific RNA increases hair stem cell growth and skin healing by affecting a protein through interaction with a microRNA.

In this study, researchers found that β-catenin directly promotes TERT expression in stem and cancer cells by interacting with the Tert promoter, illustrating a mechanistic link between tumorigenesis and pluripotency.

Regulatory T cells help prevent autoimmunity and have potential for treating autoimmune diseases.

This study found that SM04755, a novel topical drug, inhibited inflammation, keratinocyte proliferation, and fibrosis in vitro and improved skin health in a mouse model of psoriasis, indicating potential as a topical psoriasis treatment.

Specific immune cells cause alopecia areata and blocking certain proteins can prevent it.

This study found that AIRE, a usually nuclear protein, is expressed in the cytoplasm of human epidermal and follicular keratinocytes and associates with the intermediate filament protein cytokeratin 17, potentially impacting ectodermal abnormalities in APECED syndrome.
