This review discusses the impaired functionality of regulatory T cells in the pancreas during the development of Type 1 diabetes, highlighting their role in disease pathogenesis, potential of Treg-based therapies, and challenges in clinical applications.

This study suggests that allogenic human mesenchymal stem cell treatments have potential therapeutic effects by inducing immune tolerance and anti-inflammatory effects in severe alopecia areata patients.

This study found that human γδTregs promoted hair regrowth and restored hair follicle immune privilege in a model of alopecia areata, suggesting potential for cell-based therapy in autoimmune diseases.

This study found that specific immune cell phenotypes, particularly CD25 on CD4 Treg cells, were causally linked to androgenic alopecia, suggesting potential targets for immune-based therapies.

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 discusses the features of regulatory T cells and the modulation of Foxp3, emphasizing post-translational modifications' impact on Treg function but reports no new clinical results.

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 study found that administering gingerol improved survival and reduced organ damage in mouse models of chronic graft-versus-host disease by modulating T cell differentiation and inflammatory cytokines, suggesting a novel therapeutic approach for steroid-refractory cases.

This study identified a high proportion of dual TCR Treg cells in both lymphoid and non-lymphoid tissues of mice, revealing their tissue specificity, TCR repertoire characteristics, and functional phenotypes.

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 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 study found that patients with Alopecia areata in Iraq had significantly higher levels of CD4+, CD39+, and FOXP3+ Treg cells in their blood compared to healthy controls.

This review discusses the role of the skin microbiome in maintaining health and modulating atopic dermatitis, emphasizing the need for novel therapeutic strategies, but reports no new 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 review discusses the role of regulatory T-cells in tissue repair and regeneration across various organs and reports no new clinical results.

This review discusses immune privilege in anagen hair follicles and its collapse in alopecia areata, emphasizing the importance of restoring this function for effective management and disease relapse prevention.

This study found that chronic eczema supports the expansion of myeloid suppressor cells, which contribute to silencing autoreactive T cells and partially promote hair regrowth in alopecia areata.

This review explores the hair follicle microbiome's interaction with the immune system, discussing its potential clinical implications for scalp health and disease but reports no new clinical results.

This study found that patients with alopecia areata had higher levels of Th17 cells and lower levels of regulatory T cells compared to healthy controls, suggesting an immune imbalance in these patients.

This review discusses progress in targeted therapies for vitiligo, focusing on Janus kinase inhibitors and the potential of mesenchymal stem cells, but reports no new clinical results.

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.

This study found that a specific mutation in the mouse RXRalpha gene significantly impacts immune responses and causes hair loss and skin cysts.

This review discusses the effects of valproic acid on immune cell activation and gene expression, potentially influencing infection outcomes and suggesting its promise for autoimmune and hypersensitivity condition management.

This study found that MDSC exosomes promoted partial hair regrowth and modulated immune responses in mice with alopecia areata, suggesting potential as a treatment for autoimmune diseases.

This review examines the role of regulatory T cells in skin immune disorders, highlighting their unique functions in conditions like scleroderma, alopecia areata, and psoriasis, without reporting new clinical results.

This review discusses the genetic, autoinflammatory, and keratinization factors involved in hidradenitis suppurativa and presents the concept of classifying it as an autoinflammatory keratinization disease, but reports no new clinical results.

This study found that Malt1, particularly its protease activity, plays a crucial role in maintaining Treg cell function and homeostasis, with its inactivation leading to autoimmune diseases and altered immune responses in mice.

Alopecia areata patients have more activated T cells in their blood, which may help in developing treatments.
