This study identified shared gene expression changes and immune cell infiltration patterns that may contribute to hair loss in alopecia areata and cutaneous lupus erythematosus, but also highlighted factors that might preserve hair in psoriasis patients.

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.

Immune cells called Treg cells are essential for hair growth and regeneration.

This study found that atopic diseases such as atopic dermatitis, asthma, and allergic rhinitis increase the risk of developing alopecia areata, suggesting a significant role for T cell-related inflammation in the condition's mechanism.

This review discusses the potential of combining low-dose IL-2 with islet antigens to enhance antigen-specific Treg function in type 1 diabetes, but reports no new clinical results.

This study suggests that low-dose IL-2 and IL-15 may help restore immune tolerance in alopecia areata by maintaining Treg cell function, presenting a potential new treatment strategy.

Increased Treg cells and IL-10 may help quick recovery in acute diffuse and total alopecia.

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 review discusses recent insights into the role of regulatory T cells in psoriasis and the impact of current treatments on their function, but reports no new research findings.

This study found that during wound healing, hair follicle stem cells develop an immune modulatory ability to create a protective immune suppressive niche, facilitating their survival and function amidst inflammation.

This review discusses the role of regulatory T cells, highlighting recent research on how prostanoids may modulate their function, but it reports no new findings.

This review explores the role of regulatory T cells in autoimmune skin disorders like alopecia areata and vitiligo, emphasizing unanswered questions and reporting no new experimental results.

This mini-review details how the SOX family of transcription factors contributes to cancer immune evasion by affecting antigen presentation, impacting the tumor's immunosuppressive environment, and regulating immune checkpoints, offering insights for developing novel immunotherapy strategies.

This review discusses how regulatory T cells may also promote tissue regeneration through specialized pathways, in addition to their traditional role in maintaining immune tolerance, but reports no new experimental results.

This study found that IL18 signaling plays a crucial role in the homing and retention of mature regulatory T cells in the mouse thymus, primarily by upregulating the chemokine receptor CCR6.

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.

In this experimental study, laser irradiation significantly altered the gene expression of cytokines in cultured human T-cell lymphocytes, suggesting that such laser light may photobiomodulate cytokine production in vitro.

This study found that reduced expression of CD200R1 on monocyte-derived macrophages in rheumatoid arthritis patients was significantly associated with higher disease severity and an imbalance in Th17/Treg cells.

This review examines the potential of regulatory T cell-based therapies to transform treatment across various medical specialties by promoting immune tolerance and tissue repair, but it reports no new clinical results.

This review discusses the essential roles and complex regulation of PP2A in various physiological processes and reports no clinical results; the authors highlight the need for further mouse model research to explore PP2A's therapeutic potential.

This research highlighted that the gut microbiota may influence ovarian health, suggesting it could be used as a biomarker for early diagnosis and treatment of diseases like PCOS, ovarian insufficiency, and ovarian cancer due to its impact on hormone levels.

The skin protects the body, regulates temperature, senses touch, and makes vitamin D.

This review discusses strategies to enhance mesenchymal stem cell therapy effectiveness but reports no new clinical results; it highlights the need for improved consistency and efficacy in MSC-based treatments.

In this study, researchers found that androgenetic alopecia is associated with increased gene expression related to inflammation, stress, and fibrosis, particularly affecting the hair follicle stem cells and showing similarities to diseases like psoriasis.

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 study investigated dual TCR Treg cells in mouse tissues, revealing a high proportion and diverse pairing patterns compared to single TCR Tregs, providing insights into their origins and characteristics across different tissue locations.

This review discusses the role of Toll-like receptors in wound healing and highlights their potential therapeutic value but notes that their role in human wound healing and chronic wounds is not well understood.

This review discusses the origins of skin and esophageal cancers and reports no clinical results; it emphasizes the role of cyclooxygenase-2 in tumorigenesis and differentiation.

In this study, researchers analyzed over 5,000 T cells per sample using scRNA+TCR-seq technology and found that dual TCR Tregs are present in high proportions across various mouse tissues, showing unique TCR pairing patterns, V(D)J usage, and mRNA expression compared to single TCR Tregs.

This review summarizes existing knowledge of how the WNT signaling pathway affects mesenchymal stem cells under various conditions, highlighting challenges and mechanisms for clinical applications.
