This study observed that PD-1+CXCR5-CD4+T peripheral helper cells are significantly elevated in patients with systemic lupus erythematosus and are correlated with disease activity indicators, suggesting their potential role in lupus pathogenesis.

This article presents a diagnostic quiz based on clinical images and reports findings from the mentioned article but does not provide new clinical results.

This study found that IL-7 is crucial for the survival of memory regulatory T cells in the skin of mice, whereas IL-2 is essential for their initial generation but not for their maintenance.

This study found that CD1a-restricted CD4+ T cells responsive to lysyl-phosphatidylglycerol were more frequent in the blood of atopic dermatitis patients, suggesting a potential role in the disease's Th2-mediated pathology.

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 found that antroquinonol inhibited CD8+ T cell proliferation and reduced proinflammatory cytokine secretion in vitro, while also ameliorating H2O2-induced depigmentation and resisting reductions in hair follicle length, skin thickness, and tyrosinase expression in mice.

This study observed that expanding regulatory T cells in the skin of mice with alopecia areata did not reverse the condition, indicating that additional immunotherapy may be necessary.

This study demonstrates that T-cell responses in extensive alopecia areata scalp may be aberrantly regulated, with reduced cytokine production but activated phenotype, providing insight into the disease's immune mechanisms.

T cells affect skin cell genes in inflammatory diseases, and therapy can normalize these changes.

This study found that overexpression of miR-1246 in peripheral CD4+ T cells can reduce markers associated with inflammation and T cell activation in severe active alopecia areata, suggesting potential therapeutic benefits.

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 intracellular Toll-like receptors were significantly up-regulated in peripheral blood mononuclear cells of alopecia areata patients, suggesting a potential role in inflammatory signaling and pathogenesis.

This review discusses how recent studies use models and experiments to understand immune system signaling, but it reports no new clinical findings; the authors suggest strategies for improving these models.

This review discusses the potential of JAK inhibitors as a promising treatment strategy for alopecia areata, highlighting their mechanism and recent FDA approval based on clinical trial efficacy.

In this study, nearly 5% of anti-TNF-treated patients with IBD developed psoriasiform skin lesions, with smoking identified as a main risk factor, and ustekinumab proved highly effective in severe cases.

Recent dermatological research highlights include new virus discoveries, genetic links to skin conditions, and insights into skin healing and pigmentation.

This study identified key genetic regions associated with alopecia areata, highlighting both acquired and innate immune involvement, with a novel link to the upregulation of ULBP ligands in autoimmune disease.

JAK inhibitors and platelet-rich plasma show promise for treating alopecia areata.

In this study, CD4+CD25+FoxP3+ Regulatory T cells were found to reduce TGF-b1 induced lung fibrosis and fibrocyte accumulation in mice, partly by suppressing fibroblast growth factor 9.

In this study, increased Treg cell activity indicated by IL-10 and IL-15 was identified as a feature of ADTA, distinguishing it from AA and potentially explaining ADTA's more favorable prognosis.

In this study, researchers found that using a 5-α reductase inhibitor may reduce inflammation-related cytokines associated with T-helper cell 1 and T-helper cell 2 in prostate tissues after surgery, but it did not affect those related to Th17 cells.

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 CD45RO+ cells, a subtype of T lymphocytes, were notably reduced in the ovarian follicles of women with PCOS, which may contribute to the condition's pathogenesis.

This study found that orally administering the CCR5 inhibitor Maraviroc improved hair loss in 4 out of 5 mice with alopecia areata and also reduced the development of the condition, evidenced by decreased CCR5+ T-cell infiltration in treated mice.

In this study, the elimination of NG2+ hair follicle stem cells during the anagen phase was associated with an aggravated sensitization phase of allergic contact dermatitis, suggesting their immunosuppressive role.

This study found that thymus transplantation in infants with FOXN1 deficiency led to T-cell reconstitution and functional immunity, resolving serious infections and cytopenias.

In this study using mouse models, researchers found that elevated IL-17a in aged olfactory epithelium impairs olfactory function, while IL-17a inhibition promotes regeneration and mitigates age-related decline.

This study found that Th17 lymphocytes may play a more crucial role than cytotoxic T cells in the development of alopecia areata due to their infiltration around the hair bulb/bulge, which exacerbates hair loss as histopathological grade worsens.

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 found that IL-17A-producing γδ T cells play a key role in bone fracture healing by promoting bone formation, with deficiencies leading to impaired repair in mice.
