Sobre

Professor of Pharmacology at ICB-USP and a biologist by training, he has built his scientific career in cardiovascular pharmacology, focusing on how estrogen and aging modulate vascular function through pathways associated with oxidative stress and metabolic changes. The goal is to understand sex differences in the genesis of cardiovascular diseases. During his postdoctoral work at the School of Medicine of Ribeirão Preto and at Johns Hopkins University, he deepened his studies on arterial stiffness, estrogen signaling, and O-GlcNAc-mediated cellular stress responses. The lab he leads thus seeks to understand how age, sex, and O-GlcNAc influence vascular adaptation to stress, aiming to develop new cellular reprogramming strategies and advance the understanding of cardiovascular diseases.

About the research:

Cardiovascular disease is the leading cause of death, and various forms of cellular stress contribute to its onset. Endothelial cells, for example, are exposed to variations in blood pressure, changes in blood flow, inflammatory processes, and metabolic challenges. A question naturally arises: how do cells survive stress? They do so by activating mechanisms that result in phenotypic modifications and the activation of metabolic pathways, such as O-GlcNAc. Yet a question remains: in a stress scenario, which mechanisms promote cellular resilience, rather than phenotypic change? Our goal is to understand how certain cells reprogram themselves to resist stress and, beyond that, how they communicate with neighboring cells to coordinate collective responses of adaptation, survival, and functional preservation.
