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 found that a specific T-cell receptor motif associated with lipid-antigen stimulation may play a role in the pathogenesis of folliculotropic mycosis fungoides.

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.

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.

In this study, activating TRPV1 nociceptors in mice skin stimulated dormant hair follicles and promoted hair growth through a mechanism involving dermal macrophages, fibroblasts, and neuropeptides, highlighting a new role for nociceptors in tissue recovery after injury.

The researchers reported that hair follicle development and commensal microbe colonization promote the accumulation of regulatory T cells in neonatal skin, with the Ccl20-Ccr6 pathway playing a key role in this process.

This study found that deficiency in TLR3/TRIF signaling reduced inflammation and protected mice against postoperative ileus, suggesting potential for TLR3 antagonism as a preventive approach in humans.

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

In this study, researchers found that the cell surface protein Lrig1 plays a crucial role in regulating the suppressive function of regulatory T cells, suggesting it as a potential target for treating autoimmune diseases, as evidenced by experiments in mouse models.

This study found that thyrotropin-releasing hormone (TRH) acts as a potent stimulator of hair growth in human scalp hair follicles, promoting elongation and prolonging the anagen phase.

New research suggests that skin cell renewal may not require a special type of cell previously thought to be essential.

This study demonstrates that Krt15 marks long-lived, multipotent, and injury-resistant crypt cells in the small intestine, which may serve as the cell of origin in intestinal cancer.

This study found that skin-resident Treg cells regulate hair follicle stem cell proliferation and differentiation through the Jag1-Notch signaling pathway, influencing hair regeneration.

In this study, rheumatoid arthritis patients showed no changes in the number of circulating follicular helper T cells, but these cells had increased CD200 expression, implicating them in disease pathogenesis and suggesting CD200/CD200R as a potential therapeutic target.

TRH in hair follicles can influence hair color by increasing melanin.

New findings suggest targeting IL-23 could treat psoriasis, skin cells can adapt to new roles, direct conversion of skin cells to blood cells may aid cell therapy, removing certain tumor cells could boost cancer immunotherapy, and melanoma may have many tumorigenic cells, not just cancer stem cells.

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.

Certain immune cells help hair growth by regulating iron in the skin.

This study suggests that targeting skin-infiltrated memory phenotype T cells could offer a new therapeutic approach to manage lymphopenia-related diseases like graft-versus-host disease and immune reconstitution inflammatory syndrome.

Targeting TCR-Vβ2 in cutaneous T cell lymphoma shows promise for safer, more specific treatment.

This study found that a specific macrophage subpopulation in the dermis helps maintain hair follicle stem cell quiescence through cytokine-mediated signaling.

This study developed a technique to limit genetic recombination to regulatory T cells to investigate whether self-tolerance is maintained in non-lymphoid tissues, an area previously not well understood.

In this study, researchers explored various aspects of the TRPV3 ion channel, including its novel mechanosensitivity to shear stress, and identified novel agonists while investigating how repeated stimulation affects TRPV3 activity, but found no evidence of GPCRs sensitizing the channel.

This review explores the crucial role of regulatory T cells in skin wound healing, emphasizing their involvement in balancing immune responses and promoting regeneration. It also discusses Tregs' operations in fibrosis, keloidosis, and scarring, suggesting a potential avenue for novel treatments.

In this study, gamma/delta T cells were observed in skin after allergic or irritant reactions to heavy metal salts, suggesting a role in skin defense against these metals.

This study found that immunohistochemistry can effectively distinguish between tricholemmoma and basal cell carcinoma, with BerEP4 and CD34 serving as key differentiators.

This study found that direct co-culture of human bone marrow-derived mesenchymal stromal cells with regulatory T cells enhanced osteogenic gene expression, alkaline phosphatase activity, and matrix mineralization, suggesting Treg's potential in promoting bone regeneration by modulating BMSC mechanobiology through the ROCK-myosin signaling pathway.

This study found that the postnatal thymus contains a population of mesenchymal stem cells that may help maintain functional thymic microenvironments.

In this study, researchers identified a specific T cell receptor associated with carbamazepine-induced severe cutaneous adverse reactions, demonstrating its potential for therapeutic development in patients with the HLA-B*15:02 genotype.

This study found that TRPV3 activation in human sebocytes inhibits lipid synthesis and triggers proinflammatory cytokine expression, suggesting a role in the pathogenesis of dry skin-associated inflammatory dermatoses.
