Research Description

Obesity is now known to generate a state of chronic low-grade inflammation.  Importantly, many of the negative health effects of obesity, such as metabolic syndrome and type 2 diabetes, are related to this inflammation.  Adipose tissue itself contains a number of immune cells, and obesity is associated with the accumulation and activation of macrophages and Th1 lymphocytes within this tissue.  Relatively little is known about how these cells interact and, ultimately, what influence this interaction has on disease and immunity.  Research is focused on studying the mechanisms by which adipose tissue macrophages shift from an M2 to an M1 state and how this relates to T cell activation and suppression in adipose tissue with obesity.
