A UCLA study finds the Kdm6a gene on women’s X chromosomes drives higher brain inflammation, increasing risk for Alzheimer’s and other conditions.
A UCLA study identifies the Kdm6a gene on the X chromosome as a key factor in higher brain inflammation in women, explaining their increased risk for Alzheimer’s, multiple sclerosis, and menopausal brain fog.
Women’s two X chromosomes result in a double dose of the gene, driving inflammation in microglia.
In female mice, turning off Kdm6a or using metformin reduced inflammation and symptoms, while estrogen decline during menopause may remove protective effects.
The findings, published in Science Translational Medicine, highlight sex-based biological differences and point to potential treatments like brain-specific estrogen therapies.
Un estudio de UCLA encuentra que el gen Kdm6a en los cromosomas X de las mujeres impulsa una mayor inflamación cerebral, aumentando el riesgo de Alzheimer y otras afecciones.
