Macrophage subsets in the adipose tissue could be modified by sex and the reproductive age of women

Atherosclerosis

Abstract

The presence of proinflammatory monocytes/macrophages (CD14+CD16+) has been documented in conditions of inflammation, such as atherosclerosis. We analysed the proportion of proinflammatory monocytes/macrophages in perirenal and perivascular fat in healthy living kidney donors with regard to sex and age reflecting reproductive status in women; therefore, women were further divided to younger and older group (younger and older than 51 years) reflecting potential age of menopause. Monocyte/macrophages were identified as CD14+ mononuclear cells and divided into subpopulations based on the co-expression of CD16. We found no differences in the monocyte/macrophage content between men (n = 15) and women (n = 28). Conversely, we observed a higher proportion of double positive CD14+CD16+ monocytes/macrophages in older women (n = 14) compared to younger women (n = 14). In addition, a strong correlation was found between the monocyte/macrophage content in fat and age only in older women. Therefore, proinflammatory monocytes/macrophages (CD14+CD16+) should be evaluated according to the sex and age.

Anti-inflammatory Treatments

A drug or substance that reduces inflammation (redness, swelling, and pain) in the body. Anti-inflammatory agents block certain substances in the body that cause inflammation and swelling. Discover the latest research on anti-inflammatory treatments here

Cardiovascular Inflammation

Inflammation plays a significant role in the development of cardiovascular diseases, an understanding of these endogenous processes is critical for evaluating the risks and potential treatment strategies. Discover the latest research on cardiovascular inflammation here.

Cardiovascular Disease Pathophysiology

Cardiovascular disease involves several different processes that contribute to the pathological mechanism, including hyperglycemia, inflammation, atherosclerosis, hypertension and more. Vasculature stability plays a critical role in the development of the disease. Discover the latest research on cardiovascular disease pathophysiology here.
