Endocrinology Research


The division conducts promising state-of-the-art research to generate new knowledge and improve understanding with the ultimate goal of applying the latest scientific and medical advances for the prevention, detection, and treatment of patients with endocrine diseases.

The focus of Dr. Alonso’s lab is to understand the molecular pathways that trigger pancreatic beta cell proliferation, to find approaches to make more beta cells to prevent or treat diabetes. Using knockout and transgenic mice, and human and mouse pancreatic tissue in culture systems, she is particularly interested in the intriguing relationship between the beta cell workload response and generation of new beta cells.

The Goncalves’ lab uses animal models and human clinical trials to understand the effects of diet (e.g. ketogenic, fructose) and cancer on the metabolic pathways that control fat and muscle mass. Dr. Goncalves’ clinical practice is focused on metabolic diseases that are associated with high blood sugar (prediabetes, diabetes, fatty liver disease, high cholesterol) or the loss of skeletal muscle mass (low testosterone, cancer cachexia, etc).

The focus of Dr. Anthony Hollenberg’s laboratory is the molecular action of thyroid hormones. Dr. Hollenberg was among the first to identify that thyrotropin-releasing hormone (TRH) neurons in the hypothalamus serve as integrators of metabolic input, setting thyroid hormone levels within the context of body weight. He was also among the first to identify the role of specific co-repressors in negative regulation by the thyroid, helping to establish the idea that hormone sensitivity is due to the quantity of co-repressors present. Dr. Hollenberg has had an independent research laboratory since 1993 and with continuous funding from the NIH since 1995. Recently, the Hollenberg Laboratory has begun a new program investigating the development of functioning thyroid follicular cells from embryonic stem cells.

The Vella Lab’s long-term goal is to therapeutically target the mechanisms controlling the setpoints of the Hypothalamic-Pituitary-Thyroid (HPT) Axis to improve weight loss efforts. 90% of individuals who lose weight ultimately return to their previous weight within 5 years due in part to a suppressed basal metabolic rate (BMR). Thyroid hormone a major regulator of BMR. We use mouse models and chemogenetics to investigate the neuronal inputs that regulate the HPT axis, thyroid hormone levels and ultimately BMR.
