Antonio Bianco is a physician-scientist working in the thyroid field. His studies have focused on how the systemic hormone T3 initiates or terminates critical biological steps while maintaining relatively stable levels in the circulation. As a graduate student, he discovered the molecular link between deiodination and thermogenesis, specifically that the UCP-1 gene, key for brown adipose tissue thermogenesis, is transcriptionally stimulated by T3. This finding inspired further research on how deiodinases can modify intracellular T3 levels and signaling without antecedent changes in plasma TH levels. Over the years, the work in his lab has established the importance of “local” control of TH metabolism provided by deiodinases. From a broad perspective, this work has inspired the modern paradigm that deiodinases regulate thyroid hormone signaling on a tissue-specific basis, playing critical roles in human health and disease. He also served in different administrative capacities and as President of the American Thyroid Association (2015-16).
