September 2024 in “South Eastern European Journal of Public Health” This study found that patients with alopecia areata had increased levels of serum immunoglobulin E and interleukin-13 compared to healthy controls, with additional variation in levels observed across age and weight.
July 2025 in “Chinese Journal of Dermatology” This study reported differences in serum IgG N-glycans between male patients with different types of androgenetic alopecia, suggesting that GP10 and GP22 may serve as biomarkers for assessing hair loss severity in male FPHL.
July 2020 in “Research Square (Research Square)” This study identified 21 candidate genes linked to immunoglobulin levels in colostrum and serum of dairy cattle, suggesting potential for genetic selection to enhance immunity.
September 2020 in “Research Square (Research Square)” This study identified 21 candidate genes related to immunoglobulin concentrations in colostrum and serum of dairy cattle, which may aid in genetic improvement for disease resistance.
February 2025 in “Animals” This study involving 81 yaks found significant correlations between melatonin, dihydrotestosterone, and immunoglobulin levels in blood serum and mineral content in hair, suggesting these factors may jointly influence yak hair growth and immune status, providing a potential non-invasive indicator of overall health.
