This study found no increased frequency of the TNF2 allele in Mexican patients with adverse cutaneous drug reactions mediated by delayed hypersensitivity, suggesting its lower relevance compared to findings in Caucasian populations.

In this review, researchers explored the multifaceted role of NF-κB signaling in various biological processes and diseases, including its interactions with other pathways, and discussed possible therapeutic approaches targeting this pathway for treating conditions like cancer, autoimmune disorders, and COVID-19.

This case study highlights an unusual presentation of folliculitis decalvans by age and sex, emphasizing early diagnosis due to its chronic nature and irreversible consequences.

This review discusses the various off-label treatments for alopecia areata, highlighting that these therapies may promote hair growth but are not curative.

This review discusses the long-term complications of COVID-19, known as long COVID or PASC, and emphasizes the need to improve awareness and management strategies but reports no new clinical findings.

This article reviews potential pathomechanisms of vitiligo, emphasizing membrane alterations involving cholesterol and cardiolipin, but reports no new clinical findings.

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 plasmacytoid dendritic cells may initiate alopecia areata in mice by overexpressing interferon-alpha.

This study found that dysregulated microRNA expression in mice may be linked to aberrant gene activity that contributes to the development of alopecia areata.

This study examined immune responses to Diphencyprone and found that its induced skin reactions have higher levels of negative immune regulators compared to psoriasis, suggesting differences in immune regulation may contribute to psoriasis chronicity.

This study found that ILC1-like cells can induce alopecia areata symptoms in both ex vivo human hair follicles and in vivo mouse models, challenging the view that alopecia areata is solely CD8+ T cell-driven.

Vitiligo is caused by the immune system attacking skin pigment cells.

In this abstract, the issue of "microinflammation" in hair follicles, central to androgenetic alopecia, is described as involving an inflammatory process with Langerhans cells and keratinocytes presenting antigens to T lymphocytes, leading to an immune response with macrophages or natural killer cells destroying these antigens.

Targeted immunotherapy could be a promising new treatment for hair regrowth.

This study in a murine model of alopecia areata found that IFNg is crucial while perforin is not necessary for CD8 T cell-mediated disease development.

This study found that anagen stage protein homogenates and specific epitopes from melanogenesis proteins activated CD8 T cells, suggesting alopecia areata is an anagen-specific disease.

This study in SPF lambs found that primary and secondary orf virus infections trigger similar skin responses, but the primary infection caused a more severe and prolonged reaction.

In this study, researchers observed that dysregulated innate lymphoid cells type 1, alongside CD8+ T cells, may contribute to the pathogenesis of alopecia areata by affecting hair follicle health.

This study suggests that sweat glands may have an immune privilege similar to hair follicles, and disruptions in this could contribute to autoimmune skin diseases.

This source discusses autoimmune disorders, noting that the presence of autoantibodies can precede disease development, especially in genetically predisposed individuals, with various triggers like vitamin D deficiency and UV exposure potentially influencing onset and severity.

This paper discusses the evolving understanding of psoriasis pathogenesis with no new clinical findings; the authors highlight the role of T-cell plasticity and regulatory cells, calling for further clinical applications using single-cell technologies.

This review discusses androgenetic alopecia and alopecia areata through a systems biology lens, emphasizing the role of multi-omics data integration to explore molecular mechanisms and potential therapeutic strategies, but offers no new clinical results.

This chapter reviews fungal skin diseases in pigs, including urticarial and autoimmune conditions, but does not report new clinical findings.

This study demonstrated that antigens from the skin bacterium Staphylococcus epidermidis can stimulate CD8+ T cells, which in turn enhance wound healing.

This study found IL-17/IL-36 signaling to be predominant in both endotypes of Netherton syndrome, with distinct molecular profiles between NS-ILC and NS-SE lesions, offering potential therapeutic targets.

Immunocompromised patients can develop skin and hair issues due to a virus.

This study supports the idea that inflammation may play a role in the development of androgenetic alopecia, as indicated by certain immune deposits and porphyrins found more frequently in bald scalp biopsies compared to controls.

This study analyzed pediatric and adult patients with antibody deficiencies at a PID center, finding frequent severe infections and genetic mutations, with treatment primarily involving IVIG replacement therapy.

This study found that alopecia areata patients who responded poorly to topical immunotherapy had impaired peripheral blood mononuclear cell responses to T-cell stimulants.
