About

Richard Lehner is a leading figure in lipid metabolism, whose research has fundamentally reshaped our understanding of how the body processes and stores fat. His key contributions center on the molecular mechanisms of lipolysis and hepatic lipid homeostasis, particularly the role of carboxylesterases in energy balance. In a landmark 2004 study, cited over 150 times, Lehner identified carboxylesterase 3 (Ces3) as a major adipocyte lipase, challenging the long-held dogma that hormone-sensitive lipase (HSL) was the sole driver of triglyceride hydrolysis in white adipose tissue. By demonstrating active HSL-independent lipolysis in knockout mice, his work uncovered a parallel pathway critical for energy mobilization. This discovery has profound implications for metabolic diseases like obesity and type 2 diabetes. Beyond this, Lehner has extensively characterized hepatic lipases and their role in very low-density lipoprotein (VLDL) assembly, earning him a reputation for rigorous, mechanistic research. His findings have not only advanced basic science but also opened new therapeutic avenues for dyslipidemia. With a career marked by high-impact publications and sustained citation influence, Lehner remains a pivotal voice in the study of adipose and liver lipid dynamics.
