Effect of fat cell size, restrictive diet and diabetes on lipoprotein lipase release by human adipose tissue

Abstract

The lipoprotein lipase activity (LPLA) eluted from human adipose tissue was measured after percutaneous biopsy in the fasting state. A positive and significant correlation was found between LPLA per 10(6) cells or per cell surface unit and cell volume in 27 normal and obese subjects in weight balance and on maintenance diet. Such a correlation was also found in 13 diabetic subjects before treatment. In 11 obese subjects subjected to a restricted diet, LPLA dropped dramatically without a significant change in cell size, blunting the cell size effect. In diabetic subjects the LPLA per cell was significantly lower than in nondiabetic people with similar adipose cell volume.

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.
