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

This article discusses the role of regulatory T cells in alopecia areata, where their deficiency in hair follicles may lead to impaired local immunity and suggests potential therapies like CAR-T reg cells and low-dose IL-2 to alleviate autoimmunity and promote hair regeneration in affected individuals.

This study shows that IKZF1 and the protein IKAROS may play a role in the development of alopecia areata, based on findings from both mouse models and human scalp tissues.

This study found no significant association between the IL-15 genetic polymorphism (rs17015014) and the risk or severity of Alopecia Areata in the examined population.

This report describes a case of alopecia universalis successfully treated with tofacitinib, though it was associated with increased peripheral blood cytokine levels.

The authors propose that higher testosterone levels in hospitalized COVID-19 patients might be associated with worse outcomes.

This review discusses the potential of ginseng and its metabolites for treating hair loss and reports no new clinical findings.

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 outlines the proposed theories behind the development of alopecia areata, emphasizing the autoimmune process involving lost immune privilege in hair follicles, and stresses the need to pinpoint specific pathogenic mechanisms for potential treatments.

This review discusses potential biomarkers for alopecia and their significance, and while it highlights areas for future research, it reports no new clinical results.

This study found that both Th1 and Th2 cytokine markers were elevated in the serum and skin of patients with alopecia areata, with Th2 markers more closely linked to disease severity.

This study found that plasmacytoid dendritic cells may initiate alopecia areata in mice by overexpressing interferon-alpha.

This study suggests that the exercise-induced cytokine IL-15 can improve wound healing in aged skin, along with previously reported benefits on skin structure and mitochondrial function.

This review discusses the use of Janus kinase inhibitors for severe alopecia areata in Japan, noting their effectiveness in some patients but highlighting the need for new therapies due to non-responsiveness and relapse in others; it reports no new clinical results.

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

The study reported that patients with alopecia areata had significantly higher serum levels of IL-17A and IL-2 compared to healthy controls, suggesting these interleukins may play an important role in the disease, though they did not correlate with its severity or duration.

This study found that NK and CD8+ T cell infiltration may drive inflammation in androgenetic alopecia, suggesting that targeting IL-15 signaling could offer a new therapeutic approach for hair regeneration.

This study found that rhIL-15 promotes human hair follicle growth and regrowth in experimental settings and may have therapeutic potential for alopecia areata by restoring immune privilege guardianship.

In this study, researchers observed that dandruff involves altered keratinocyte activity and a low-grade inflammatory response characterized by increased interleukin-17-producing T-cells and CCL17 levels, but without significant changes in immune cell populations or skin barrier lipids.

This study examined molecular predictors of ritlecitinib efficacy in treating alopecia areata, highlighting the role of JAK3-dependent inflammation and follicular integrity as important factors in understanding disease mechanisms and potential therapeutic effectiveness.

This review explores the complex factors involved in alopecia areata, such as immune and genetic influences, and discusses advances in diagnostic and therapeutic approaches, while reporting no new clinical results.

This review suggests that mucosa-associated invariant T cells may regulate the host response to SARS-CoV-2 and could be potential targets for COVID-19 management, but it reports no new clinical results.

This study reports a notable case of a patient with psoriatic arthritis and alopecia universalis who experienced significant improvement in both conditions after treatment with the JAK1 selective inhibitor upadacitinib, suggesting its potential efficacy for alopecia universalis, especially in cases involving inflammatory arthritis.

This review covers presentations from the 68th Annual Meeting of the Society of Investigative Dermatology and highlights research advances in dermatology, but reports no new clinical 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 study found that deleting specific super-enhancer regions in mice affects CD25 expression in a cell type-specific manner, leading to autoimmune alopecia in some cases and revealing distinct regulatory mechanisms for constitutive and inducible expression of CD25.

In this study, researchers reported that IL-17C plays a key pro-inflammatory role in human skin diseases and may be a promising therapeutic target for inflammatory skin conditions.

This study identified Th22 cells as key effectors in hair regeneration driven by thymosin beta 15, suggesting they could be potential targets for hair regrowth therapies.

This study found that DC-HIL+ myeloid derived suppressor cells are increased in the blood and skin of patients with cutaneous lupus erythematosus and show immunosuppressive properties.
