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.

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

This study found that in laboratory rats, toxic concentrations of hydrogen sulfide affected the immune system differently depending on age and immune suppression status, with notable changes in immune cell levels and phagocytosis, suggesting significant roles in age-associated pathologies.

This study outlines new strategies for overcoming "cold" tumors, which are typically unresponsive to cancer immunotherapy, with approaches like dendritic cell-based treatments and local immune microenvironment modification, bolstered by both preclinical and clinical trial data.

This study observed that individuals with Down syndrome had a higher incidence of autoimmune skin conditions and a lower incidence of certain viral infections, indicating unique immune system dysregulation.

In this study, researchers used spatial transcriptome profiling to identify immune disturbances in the peri-infundibular region of androgenetic alopecia patients’ hair follicles, finding increased CD4+ T cells with a bias toward Th2 immune responses compared to controls.

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 study found that a lotion with 5% minoxidil significantly altered immune parameters and disrupted immunological balance in guinea pigs, suggesting a substantial impact on both cellular and humoral immunity.

This study suggests that interleukin-15 plays a complex role in alopecia areata, potentially contributing to immune infiltration while also protecting against hair follicle immune privilege collapse and promoting hair growth.

This study found that calprotectin induces complex multi-metal starvation responses in Pseudomonas aeruginosa, affecting its metal homeostasis pathways and resistance to polymyxin B.

This study found that patients with autoimmune skin diseases showed a statistically significant occurrence of hearing disabilities, suggesting the need for audiological evaluations in these patients.
