Eduardo A. Nillni, PhD, professor of medicine (research), Division of Endocrinology, was an invited speaker at the University of Michigan for the seminar series on Endocrinology and Metabolism on September 16, 2007. He talked about the role of leptin in the regulation of thyrotropin releasing hormone. Nillni was invited to give a symposia lecture at the annual meeting of the American Thyroid Association held October 3-6, 2007, in New York. He discussed his recent studies related to obesity and leptin resistance. On October 26, he was an invited speaker at Columbia University, where he discussed the role of the melanocorting system in energy balance. At the Institute of Metabolic Science, University of Cambridge, UK, he presented his work at the External Research Seminar Series last spring. In the fall he will present at the International Symposium on Signal Transduction in Health and Disease (STADY V) to be held in Tel Aviv, Israel. Nillni's laboratory recently published its findings, "Novel Regulation Mechanism of ProThyrotropin-Releasing Hormone," in the journal Endocrinology. Endocrine News magazine from the Endocrine Society hailed this work as one of the most relevant research accomplishments of the year.
