MECHANISMS, NEURAL CIRCUITS, AND BRAIN NEUROMODULATION SYSTEMS INVOLVED IN THE CONTROL OF HYDROSALINE AND HEMODYNAMIC HOMEOSTASIS

Currently, the Laboratory is developing 3 lines of research that focus on the study of different homeostatic models of regulation of the hydro-electrolyte and cardiovascular balance.

  • Project 1: addresses the study of brain mechanisms and systems involved in perinatal programming models of osmoregulation. For example, how the high-salt intake of mothers can modify the intake and excretion of water and sodium of the progeny.
  • Project 2: investigates the neuromodulation mechanisms, circuits and systems that underlie the existing sexual dimorphism in the arterial blood pressure regulation system using different models of hypertension.
  • Project 3: analyzes the mechanisms and the participation and / or interaction of different brain neurotransmission and peptide systems in the regulation of thirst, appetite for salt and renal excretion of water and sodium. We study how specific cells and pathways detect changes in osmolarity in order to arouse thirst.

Techniques used:

For the study of the hodological, neurochemical and functional characteristics of the systems that underlie the control of hydrosaline and cardiovascular homeostasis, different techniques are used in different study animal models: double and triple immunohistochemical technique, retrograde pathway markers, immunoblot, RT PCR, electrophysiological techniques (Patch clamp), transgenic animals, blood pressure recording techniques, tissue cultures, etc.
