Three molecular subtypes of advanced skin T-cell lymphoma were identified, with potential biomarkers for predicting treatment response and disease progression.

This study examined interactions between immune cells and dermal papilla cells in a patient with alopecia areata using single-cell RNA sequencing; it identified specific T cell subtypes and ligand-receptor pairs that may contribute to hair cycle disruption through inflammation.

Alopecia areata is linked to immune system differences, with specific biomarkers like CXCL9 and CXCL10 being key for diagnosis and potential treatment targets.

Lichen Planus is a less common condition affecting skin and mucous membranes, with various types and associated risk factors, challenging to diagnose, significantly impacts life quality, and may have a risk of cancerous changes in oral lesions.

This study observed two distinct groups of alopecia areata lesions based on PD-1 expression in T cells from biopsied skin samples, suggesting potential differences in subtypes or stages of the disease that warrant further investigation.

This paper discusses two preclinical models for studying alopecia areata and finds that testing new therapeutic agents should involve both the C3H/HeJ mouse model and the humanized mouse model for comprehensive insights.

This study revealed distinct cellular and transcriptomic differences among various subtypes of cutaneous T-cell lymphoma, particularly highlighting characteristics unique to folliculotropic mycosis fungoides.

This study found that Th22 cells and their cytokine IL-22 may play an important role in the pathogenesis of systemic lupus erythematosus and could serve as bioindicators for monitoring disease severity.

This study identified specific genes upregulated in skin γδ T cells involved in alopecia areata, with findings suggesting these cells contribute to disease pathogenesis through inflammatory and Th1 response mechanisms in mouse and possibly human skin.

This study found that a non-scarring alopecia in C3H/HeJ mice resembles human alopecia areata and may serve as a valuable model for studying specific subtypes of the human condition.

This study found that patients with alopecia areata, particularly those with severe cases, exhibit significant systemic immune dysregulation, including altered cell communication networks and epigenetic remodeling in immune cells, suggesting potential pathways for therapeutic targeting.

This meta-analysis found an increased prevalence of hypothyroidism in patients with lichen planopilaris compared to controls, though the exact relationship between the two conditions remains unclear.

This research investigated immune cell involvement in various types of inflammatory alopecia by analyzing gene expression data from scalp samples, revealing distinct cellular changes in conditions like Alopecia Areata, Frontal Fibrosing Alopecia, Lichen Planopilaris, and Central Centrifugal Cicatricial Alopecia, which may inform future therapeutic targets.

This review discusses the clinical features of hypopigmented mycosis fungoides in primary cutaneous T cell lymphoma and reports no new clinical results.

This review discusses the clinical and trichoscopic features of lichen planopilaris and notes its potential underdiagnosis prior to hair transplant, but it reports no new findings.

Targeting immune pathways like JAK/STAT may help treat frontal fibrosing alopecia.

This article reviews the classification, pathogenesis, and treatment options for cutaneous lupus erythematosus and reports no new clinical findings.

This review summarizes recent findings about the multi-site differentiation of tissue regulatory T cells, emphasizing the pivotal role of epigenetic remodeling, but it reports no new clinical results.

This study found that thymus transplantation in athymic mice resulted in T-cell-driven hair follicle depigmentation and loss, without multiorgan autoimmune disease, highlighting mechanisms of tissue-specific tolerance.

This paper reviews the use of interferons, particularly alfa interferon, in treating cutaneous T-cell lymphoma, noting its substantial efficacy both alone and in combination therapies with predictable, generally well-tolerated side effects.

In this narrative review, researchers outlined the role of T cells in the autoimmune pathogenesis of alopecia areata and highlighted ongoing research into therapeutic pathways, beyond current JAK inhibitors, aimed at developing new treatments for the disease.

This study found that γδ T cells play a role in regulating stromal behavior, influencing the composition and vascularity of fibrotic tissues during the foreign body response.
