Popis: Ricardo Miledi (16.09.1927-18.12.2017) is an outstanding neurophysiologist and biophysicist who made a great contribution to the study of synaptic transmission functions. He proved the key role of сalcium ions in the release of neuromediators, developed methods of receptor expression and membrane fragments integration into large oocytes that provided huge possibilities for thousands of researchers to study subtle mechanisms of transmembrane proteins function in norm and pathology. Ricardo Miledi received his MD degree in the National Autonomous University of Mexico and in 1954 he defensed his dissertation on the study of electrical nature of cardiac fibrillation in the National Institute of Cardiology (Mexico). In 1956-1958 he underwent training in Canberra Health Research Institute (Australia) in the laboratory headed by John Eccles (Nobel Prize 1963). In 1958 R. Miledi was invited to the Department of biophysics of University College London where in cooperation with Bernard Katz (Nobel Prize 1970) made a number of important discoveries in the analysis of acetylcholine receptor expression in denervated mucle; determination of the role of calcium in neuromediators release; analysis of membrane noise on neuromediator application to neuromuscular synapses; study of the effect of antibodies from patients with myasthenia gravis on neuromuscular transmission. In the early 1980s Ricardo Miledi implemented the method of functional expression in Xenopus frog oocytes of receptors and ion channels from messenger ribonucleic acid (mRNA). His heritage running the gamut is presented in more than 500 articles.
