| L.Gabriel Navar |
Luis Gabriel (Gabby) Navar was born in El Paso, Texas, in 1941. Prof.Navar is Professor and Chairman of the Department of Physiology at Tulane University Health
Science Center in New Orleans, Louisiana.
Dr Navar’s laboratory investigate hormonal and paracrine mechanisms regulating renal hemodynamics,
glomerular filtration rate (GFR), and sodium excretion. In his early work, Dr Navar focused on the tubuloglomerular feedback
mechanism and its role in renal autoregulation. This work was pivotal in integrating the field of single-nephron macula
densa - tubuloglomerular feedback with whole kidney autoregulation of blood flow and glomerular filtration rate. The development
of the isolated perfused juxtamedullary preparation has provided a unique approach to investigating how paracrine regulators
directly affect the renal mircocirculation. Prof.Navar has changed the old concept of renal functions. He explained intrarenal mechanisms mediating changes in sodium excretion that occur in response to changes in arterial pressure. This phenomenon is termed as pressure natriuresis. He is working on the pathophysiology of hypertension and altered kidney function in angiotensin II–dependent hypertension.
He was involved in editing many journals like AJP (Renal), Hypertension,American Journal of Hypertension, Kidney International, Journal of American Society of Neprhology etc.
Professor L.Gabriel Navar- the former President of American Physiological Society is the Editorial Adviser of 'Renal Biology' of BLDE University Journal of Health Sciences. He is instrumental for establishing collaboration with Tulane University,New Orleans, USA and BLDE University, Bijapur,India
