Some cells may slow melanoma growth, a protein could affect skin pigmentation, a gene-silencing method might treat hair defects, skin bacteria changes likely result from eczema, and a defensin protein could help treat multiple sclerosis.

This study found that C3H mice with prior microbial exposure developed alopecia areata at a reduced rate and had fewer associated T cells compared to controls, suggesting that prior infections might attenuate autoimmune responses related to the disease.

This study found that insulin resistance varies across different PCOS phenotypes, with the PCOM+MI+HA phenotype showing higher resistance than others.

This study presents a new mouse model for investigating chronic graft-versus-host disease, highlighting the role of human thymic tissue in developing multiorgan fibrosis driven by human immune cells.

In this study, researchers found that a PER3 gene SNP may be pathogenic for a new subtype of dyschromatosis universalis hereditaria, especially when combined with a SASH1 mutation.

In this study, monoclonal antibody B72.3 showed selective immunoreactivity to specific types of normal canine epithelial cells, primarily those involved in mucin production.

This review highlights the multifaceted roles of skin in immune and endocrine functions, stressing its contributions to psycho-immunological and psycho-endocrine responses, but presents no new research findings.

This review integrates studies on mouse models and human clinical observations to highlight the role of immune cells in skin development and how their dysregulation leads to skin disorders, suggesting potential therapeutic pathways for skin regeneration.

Contact immunotherapy can change immune responses in alopecia areata, suggesting new treatment targets.

This pilot study employed in-vivo multiphoton microscopy to visualize pigment-producing melanocytes in vitiligo patients, aiming to enhance understanding of treatment impacts and potentially improve transplantation therapies.

Targeted immunological therapies offer safer and more effective treatments for skin conditions like eczema and psoriasis.

This study found that patients with Alopecia Areata had significantly higher levels of the chemokines MIG and IP-10 compared to healthy controls, suggesting these molecules may serve as potential biomarkers for diagnosing and monitoring the condition.

In this single-cell transcriptomic study, researchers analyzed AA scalp samples and found distinct immune and nonimmune cell activation patterns, with elevated TH1/TH2 and JAK/STAT markers potentially contributing to hair follicle immune privilege disruption and disease severity.

This review explores how molecular profiling in atopic dermatitis has led to new therapeutic developments, detailing approved and potential treatments, and discusses similar advances in alopecia areata; it reports no new results.

This study found that psoriasis patients on biologic therapy had significantly lower anti-COVID19 IgG antibody levels after vaccination compared to healthy individuals not on biologic treatment.

This article reviews the cutaneous side effects of immune checkpoint inhibitors and targeted therapies for skin cancers, noting that while generally mild, these effects can influence treatment decisions and quality of life, underscoring the need for physicians to be aware of these adverse reactions.

This study found that in mice, the epidermal microenvironment reverses the oncogenic effects of GNAQQ209L in melanocytes, inhibiting their survival and proliferation through paracrine signals.

This study used advanced single-cell RNA and chromatin sequencing to investigate differences in peripheral blood cells between mild and severe alopecia areata patients, uncovering shared transcription factor motifs that may explain disease severity and open avenues for future research on therapeutic targets.

This study observed wide clinical diversity among five patients with the same VDR gene mutation causing vitamin D-dependent rickets type II, suggesting involvement of a nuclear accessory factor and a nongenomic action of the vitamin.

This study found that acne lesions and nonlesional skin in mild-to-moderate acne patients showed significant Th17-skewing and increased antimicrobials, suggesting systemic targets like IL-17/IL-23/IL-36 could be therapeutic.

A new gene mutation may allow some piebaldism patients to regain skin color in white patches.

This study found distinct gene expression profiles in alopecia areata-affected skin, suggesting T-cell mediated immune responses and unique gene profiles between different stages of the disease.

This study identified a new subset of Ret-positive sensory neurons involved in itch perception, characterized by their unique expression profile and response to specific itch-inducing molecules.

This study developed a 3D bioprinted skin model to mimic pemphigus vulgaris, providing a tool to study disease mechanisms and test targeted therapies by reproducing the architecture and pathogenic disruptions of native skin.

This study found that certain genetic variations in the OPN gene may be linked to atopic dermatitis and a higher prevalence of asthma in Caucasians.

This research investigated the role of EphA1 in embryonic and adult tissues, generating mouse models suggesting potential links to skin and colon cancer, sepsis, and post-traumatic injury.

This source reports that understanding how skin cells and immune cells interact may lead to better treatment options for inflammatory skin diseases like psoriasis and atopic dermatitis, emphasizing the role of epithelial-immune microenvironments in disease pathogenesis.
