24 Oct 2018 --- Female abdominal fat, in mice, has more blood vessels than males' which may explain why males and females differ in susceptibility to cardiovascular disease, insulin resistance and diabetes, notes research from York University, Canada. Previously, it was noted that female fat tissue tends to be more protective against health issues, such as diabetes and cardiovascular disease, than male fat tissue but the underlying reasons were not understood. Understanding the underlying mechanisms behind sex differences in cellular processes are important as they may contribute to individual's susceptibility to develop serious health issues.
