This study observed a strong negative association between the HLA-DQB1*0201 allele and the alopecia totalis/alopecia universalis phenotype in Caucasian individuals, indicating a potential protective role.
research Association between PITX2 polymorphism and androgenetic alopecia in the Indian population
This study found that specific PITX2 gene variants are significantly associated with higher risk of androgenetic alopecia in males, highlighting important genetic and environmental interactions influencing its development.
research Interleukin-15 and Tumor Necrosis Factor-α in Iraqi Patients with Alopecia Areata
This study observed that patients with alopecia areata had significantly higher serum levels of IL-15 and TNF-α compared to controls, with TNF-α levels particularly elevated in individuals with alopecia totalis, though these biomarkers were not influenced by disease duration or activity.
research 516 Possible role of ILC1 in the pathogenesis of alopecia areata (AA)
This research suggests that innate lymphoid cells type 1 (ILC1) may contribute to the development of alopecia areata, alongside CD8+ T cells, by disrupting hair follicle immune privilege and promoting features of the disease.
research Polymorphisms of the Androgen Receptor Gene and the Estrogen Receptor β Gene Are Associated with Androgen Levels in Women1
This study found that serum androgen levels in premenopausal women may be influenced by genetic variants of the androgen receptor and estrogen receptor β genes.
research Role of the Autoimmune Regulator (AIRE) gene in alopecia areata: Strong association of a potentially functional AIRE polymorphism with alopecia universalis
In this study, researchers found that the AIRE G961C variant is a significant risk factor for severe alopecia areata and early-onset cases, particularly in patients with alopecia universalis.
research Clinical Manifestations of Hyperandrogenism and Ovulatory Dysfunction Are Not Associated with His1058 C/T SNP (rs1799817) Polymorphism of Insulin Receptor Gene Tyrosine Kinase Domain in Kashmiri Women with PCOS
This study found that the INSR His1058 C/T SNP does not increase the risk of developing PCOS among Kashmiri women.
research Candidate Gene Analysis Of Alopecia Areata In Jordanian Population Of Arab Descent: A Case–Control Study
This study identified a significant genetic association between the TNFα gene and alopecia areata susceptibility in the Jordanian Arab population.
research Androgenetic alopecia and polymorphism of the androgen receptor gene (SNP rs6152) in patients with benign prostate hyperplasia or prostate cancer
In this study, researchers found that androgen receptor gene polymorphism is associated with higher androgenetic alopecia grades and PSA levels in men with benign prostatic hyperplasia, but not with prostate cancer.
research IRF2BP2 genes provide new insights into coat type and fiber composition variation in sheep
This study found that specific genetic variations in the IRF2BP2 gene influence fleece structure in sheep, with one variant completely determining coat type and another significantly modifying fiber characteristics, providing valuable insights for improving fleece quality through selective breeding.
research Author response: IL18 signaling promotes homing of mature Tregs into the thymus
This study found that IL18 signaling plays a crucial role in the homing and retention of mature regulatory T cells in the mouse thymus, primarily by upregulating the chemokine receptor CCR6.
research Association of HSPA1B SNP rs6457452 with Alopecia Areata in the Korean Population
This study suggests that the 5’UTR SNP rs6457452 of HSPA1B may be associated with the onset of Alopecia Areata and reduced susceptibility in the Korean population.
