Biochemical pharmacology and pharmaceutical technology: 1) Development and characterization of drug-delivery systems in carriers such as cyclodextrins, liposomes, Nanostructured lipid carriers; 2) Biochemistry and Biophysics applied to the study of amphiphile interaction with biomimetic systems.
Our research group focuses on the study of cell-cell and cell-matrix interactions mediated by cell junctions and their role in tissue homeostasis, particularly of epithelial tissue. The current lines of research are: 1) to understand the mechanisms of regulation of intercellular junctions in vivo and in vitro models, 2) to investigate the importance of cell-cell contact mediated by intercellular junctions in the process of cell maturation and dysfunction pancreatic beta during development and in the context of type 2 diabetes mellitus (T2D), and 3) to study the role of the intestinal epithelial barrier mediated by the occlusion junction in the pathogenesis of T2D and its regulation by the microbiota and by short-chain fatty acids. We use in the laboratory a multidisciplinary approach that integrates tissue and functional biology, confocal laser scanning microscopy, electrophysiology, physiology of intercellular/transepithelial transport, and molecular biology (Western Blot and Real-Time PCR) to define fundamentals of the structure and function of cell junctions and understand the regulatory mechanisms of these structures in vivo and in vitro models. This research can contribute to our understanding of the pathophysiological function of junctions and support research aimed at determining ways and pathways for regulating these membrane specializations with possible application in the treatment of certain diseases associated with their dysfunction.

The main purpose of our laboratory activities is to investigate the mechanisms involved in endothelial dysfunction in cardiovascular disease and how these are influenced by chronic aerobic exercise training. In this context, we are particularly interested in vascular nitric oxide bioavailability, oxidative stress, inflammation and the perivascular adipose tissue.
