This study developed a validated murine model of hypertrophic scar contraction, demonstrating similarities to human skin and observing graft contraction and tissue characteristics over time.

This study found that certain gene sets, including those involved in ligand-gated ion channel signaling and cell adhesion, are associated with Tourette syndrome, suggesting a potential neurobiological basis for the disorder.

This study found that multimetal starvation by the immune protein calprotectin triggers unique regulatory responses in Pseudomonas aeruginosa, beyond those seen with individual metal shortages.

This study demonstrated that AIRE-deficient rats exhibit key symptoms of APECED, making them a relevant model for exploring potential treatments.

This study identified several significant genetic variants associated with alopecia universalis, including a novel association with HLA-DRB5, which may play a hidden role in the disease.

This study found that ruxolitinib modulated inflammatory changes and stimulated growth factor signals by blocking the JAK-STAT pathway in an in vitro model of alopecia areata.

This study found that glioblastoma cancer stem cells avoid immune suppression by downregulating TLR4, and restoring TLR4 signaling may reduce tumor growth and self-renewal.

This research found that reduced expression of SIRT1 in human scalp tissue may contribute to alopecia areata development by inducing immune-inflammatory responses in hair follicle cells, suggesting that SIRT1 plays a regulatory role in hair follicle immunity.

This study found that systemic administration of NDP-MSH, a melanocortin receptor agonist, provided neuroprotective effects on dopaminergic nigrostriatal neurons in a mouse model of Parkinson's disease, reducing neuroinflammation and suggesting a role for regulatory T cells in these neuroprotective effects.

Hair loss may link to weaker COVID-19 immunity, suggesting possible need for extra vaccine boost.

In this review, the researchers highlight the role of fibroblasts in regulating the extracellular matrix and immune responses, emphasizing the impact on macrophages and potential therapeutic insights for fibrotic diseases and cancer.

This study found that alopecia areata patients had significantly abnormal T3, T4, TPOAbs, ANA, and lower vitamin D levels compared to healthy controls.

This study identified peripheral myeloid cells as the earliest dysregulated immune cells in PINK1 KO mice with Parkinson’s-like symptoms following intestinal infections, suggesting that PINK1 regulates gut immune functions linked to early Parkinson’s disease mechanisms.

This study indicates that individuals exposed to PPD mount varying immune responses, with either tolerance, subclinical inflammation, or allergy, suggesting no true non-responders to PPD.

In this study, researchers highlighted the high global prevalence of immune-related skin diseases like dermatitis and psoriasis, noting that females are disproportionately affected, emphasizing the need for tailored public health strategies based on sex and region.

This review explores the complex role of the Innate Immune System in rheumatoid arthritis, highlighting gaps in understanding its functions and interactions with the Adaptive Immune System, offering insights into potential biomarkers and therapeutic strategies for this challenging autoimmune condition.

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.

This source reports that platelet-rich plasma may be as effective as intralesional corticosteroids for treating patchy alopecia areata, with potential for earlier and more sustained results, while promising in vitro and animal studies on stem cells highlight the need for more clinical research.

This study identified gene sets associated with Tourette Syndrome, implicating Ligand-gated Ion Channel Signaling, Lymphocytic, and Cell Adhesion and Trans-synaptic Signaling processes in the disorder's neurobiology.

In this case report, a 2-year-old girl with severe alopecia areata experienced significant hair regrowth after 37 weeks of treatment with dupilumab and minoxidil, but the combination of treatments and possible spontaneous recovery mean the improvement cannot be solely credited to dupilumab.

This study describes a case where a 2-year-old girl with severe alopecia areata showed marked hair regrowth after 37 weeks of treatment with dupilumab and minoxidil, but due to concurrent therapies and potential spontaneous recovery, improvements cannot solely be attributed to dupilumab.

This review highlights emerging evidence that chemotherapy-induced alopecia may be driven by immune mechanisms similar to alopecia areata, involving hair follicle immune privilege collapse, and evaluates Janus kinase inhibitors as potential treatments, while cautioning about their immunosuppressive risks in cancer patients.

In this study, researchers created a detailed human skin cell atlas by analyzing over 700,000 cells, finding that disrupted communication among specific immune and stromal cell subsets may play a key role in initiating and sustaining chronic skin inflammation in atopic dermatitis.

In this study, DHT inhibited hair regrowth and promoted hair follicle miniaturization in mice, with skin-resident myeloid cells enhancing their interaction with hair follicular cells, especially in females.

This study examines the role of immune phenotypes and cytokines in the development of pathological scars, providing insights that may aid in early identification and treatment strategies for these scars.

This review discusses the mechanisms underlying the collapse of hair follicle immune privilege in alopecia areata and emphasizes the importance of therapeutic strategies aimed at restoring immune tolerance.

In this study, researchers found that serum levels of integrin, CLEC10A, and interleukin-42 significantly differed between PCOS patients treated with infertility drugs and untreated PCOS patients when compared to healthy controls, suggesting these biomarkers could help differentiate treatment status in PCOS.

This study observed that, among alopecia areata patients in Fujian, China, lower IgG4 levels and higher IFN-γ levels were statistically significant, suggesting their potential role as biomarkers for the condition and highlighting avenues for future therapeutic developments.

This case report details the first use of baricitinib in a pediatric patient with immune thrombocytopenia and alopecia areata, showing successful treatment with increased platelet counts.
