This case report suggests an immunological link between multifocal acquired demyelinating sensory and motor neuropathy and alopecia, with both conditions improving after treatment with intravenous immunoglobulin.

This study found that in biopsied skin samples of alopecia areata, a lower anagen/telogen ratio was associated with increased T cell infiltration, and enhancing the PD-1/PD-L1 axis may inhibit CD8+T cell infiltration and improve the condition.

This study suggests that contact sensitizers may treat alopecia areata by expanding suppressor cells and interfering with antigen presentation to lymphocytes.

This case report describes perifollicular melanocyte regeneration in the affected skin of a patient with bullous pemphigoid, highlighting an underreported aspect of the condition in skin of color patients, and emphasizing the need for increased awareness and earlier diagnosis in this demographic.

Sex and race affect immune responses and treatment outcomes in Hidradenitis suppurativa.

This study found that GLI1 RNA CISH was highly sensitive and specific for distinguishing basal cell carcinoma from nonfollicular epithelial neoplasms but not from most benign follicular tumors.

This study found that GNAQQ209L expression in mouse melanocytes led to reduced survival in the interfollicular epidermis due to paracrine signaling, while GNAQQ209L boosted survival in a different microenvironment.

This study describes and characterizes four cases of alopecia areata induced by immune checkpoint inhibitor therapy in cancer patients, highlighting the importance of recognizing and managing these hair-related adverse events.

This study found that in a mouse model of psoriasis, depleting CD169⁺ macrophages led to milder symptoms and decreased inflammation, suggesting these macrophages play a crucial role in psoriasis development.

In this study, researchers found varying levels of multiple autoantibody types among thyroid disorder patients, with 84.84% of those with immunological hypothyroidism reporting symptoms like weight gain and lethargy, whereas 81.81% of those with immune hyperthyroidism experienced hair loss.

This study describes a new mouse model for vitiligo that mimics key clinical features such as skin depigmentation and CD8 + T cell infiltration, providing a useful tool for in-depth research and drug discovery.

This study found that applying topical imiquimod during mid and late telogen in mice activates hair follicle stem cells and influences immune cell infiltration, promoting hair cycle entry independently of Wnt signaling.

This study found that mouse skin CD4(+) memory T cells are in equilibrium with the circulation under steady state but increase in specific clusters in response to infection or inflammation.

This case report describes a unique instance of an otherwise healthy infant with phylloid terminal hair nevus, a form of hypomelanosis without extracutaneous abnormalities.

This study identified distinct immune differences in patients with alopecia areata, particularly those with atopic backgrounds, and highlighted the OX40 axis as a potential therapeutic target for the condition.

This study found that combining hair transplantation with platelet-rich plasma treatment significantly improved hair regeneration, reduced hair loss, and minimized skin lesion areas in patients with androgenic alopecia compared to hair transplantation alone, suggesting enhanced treatment efficacy.

This review highlights that alopecia areata is characterized by three immune endotypes, and while JAK inhibitors offer temporary control, upcoming multi-omics diagnostics and immune reprogramming strategies may achieve longer-lasting remission, according to this analysis.

This mini review reports on papulopustular eruptions linked to classical EGFR inhibitors, MEK inhibitors, and amivantamab, highlighting distinct dermatologic toxicities in each treatment context and exploring underlying mechanisms and management strategies.

This review summarizes the pharmacology, mechanisms, and clinical efficacy of topical immunotherapy for alopecia areata but reports no new clinical results.

This article reviews the distinctive features of cutaneous lymphadenoma, a variant of trichoblastoma, and its differential diagnosis, but it presents no new empirical results.

This article in Experimental Dermatology does not include an abstract or any new research findings.

This study found that the DFS pattern occurs in about 28% of ANA-positive cases and is relatively frequent in autoimmune diseases, contrary to previous observations suggesting no link with these diseases.

This study found that epidermal growth factor receptor and mitogen activated protein kinase inhibitors down-regulate PD-L1 expression in human hair follicles, which may contribute to sterile folliculitis in treated patients.

This study found that nuclear beta-catenin, LEF1, and PHLDA1 expression was conserved in matrical tumors, suggesting a shared tumorigenesis process involving Wnt pathway activation.

This research explored the roles of various T cell types in chronic alopecia areata, finding that increased severity of lesions and hair loss may be linked to decreased lesional Foxp3+ Tregs, with a notable role for IL-17 and Th17 lymphocytes in the pathological process.

A woman with a rare autoimmune disorder had a blister on her eye and unique immune reaction, which was effectively treated with medication.

This correspondence reports the case of a young woman with severe lipid storage myopathy due to a rare mutation, who showed significant temporary improvement with plasmapheresis and immunoglobulin treatment before stabilizing with riboflavin and coenzyme Q10 supplementation, challenging the initial assumption of an immune-mediated condition.

This study demonstrated that human iPSC-derived melanocytes, when transplanted into mice, can reconstitute pigmented hair follicles and integrate into normal tissue, suggesting their potential as a cellular therapy for depigmentation.

This review discusses the range of cutaneous immune-related adverse events induced by immune checkpoint inhibitors and the proposed mechanisms underlying these skin reactions, but reports no new clinical results.
