The Effect of Estrogen on Microglial Inflammation in Surgically Ovariectomized Monkeys

Abstract Details

Menopause is a natural aging process in women which affects some metabolic and physiological states by reducing the gonadal steroid hormonal levels. In some cases, menopausal women can be prone to more serious health risks such as osteoporosis, cardiovascular diseases, and neurocognitive impairments such as Alzheimer’s disease due to loss of estrogen. Cognitive changes in response to hormone replacement therapy or in the absence of it have been widely studied on animal models. In this study, tissue from ovariectomized and estrogen replacement therapy treated post-menopausal monkeys were used to analyze brain inflammatory response by quantifying morphologically distinct microglial cells in the hippocampus. Specifically, we hypothesized that loss of circulating estrogen in the ovariectomized group would lead to a high number of activated microglial cells, while in the estrogen replacement therapy group, this number would be smaller indicating a lower inflammatory response. We did not find significant differences in the hippocampal volume among the three groups. Additionally, the total number or density of microglia did not differ significantly among the treatment groups, although there was a non-significant trend for microglia density to be lower in both ovariectomized and estrogen replacement therapy treated groups, as opposed to Intact controls.
