Sympathetic Motor Neuron Dysfunction is a Missing Link in Age-Associated Sympathetic Overactivity

L. de la Cruz, D. Bui, C. M. Moreno, O. Vivas

This study shows that aging affects sympathetic motor neurons, increasing their firing responses and reducing M current, contributing to sympathetic overactivity in older mice.

Aging reduces the number and function of L-type calcium channels in the membrane of cardiac pacemaker cells

O. Vivas, M. Baudot, S. Choi, V. A. Flores, L. F. Santana, C. M. Moreno

This study shows that aging reduces L-type calcium channel density, clustering, and open probability in cardiac pacemaker cells, leading to a slowdown in pacemaker rate, which can be reversed pharmacologically.

Optical measurement of voltage sensing by endogenous ion channel

P. Thapa, R. Stewart, R. J. Sepela, O. Vivas, L. K. Parajuli, M. Lillya, S. Fletcher-Taylor, B. E. Cohen, K. Zito, J. T. Sack

The paper introduces an imaging method to measure conformational changes of endogenous Kv2 voltage sensors in live tissue using a fluorophore-conjugated toxin and statistical modeling.
