Near-infrared (NIR) up-conversion optogenetics
Non-invasive remote control technologies designed to manipulate neural functions have been long-awaited for the comprehensive and quantitative understanding of neuronal network in the brain as well as for the therapy of neurological disorders. Recently, it has become possible for the neuronal activity to be optically manipulated using biological photo-reactive molecules such as channelrhodopsin...
متن کاملLight up your life: optogenetics for depression?
In the last year, several new studies have shown the po tential of optogenetic stimulation to rapidly modify depressionand anxiety-related behaviours in animal models. Optogenetic technology, as described in a previous editorial, gives a whole new meaning to “light therapy” that is potentially more effective and rapid and has fewer adverse effects than classic light therapy or pharmacological a...
متن کاملTurning up the adenosine turns off the spleen
Background Adenosine as a stress agent is well tolerated and has a good safety profile but occasionally when administered at 140mg/kg/min it fails to produce a haemodynamic or symptomatic response. Studies have reported that between 4 18% patients do not respond to the standard dose . Splenic switch-off is a novel way of assessing adequacy of hyperaemic response, to adenosine. The aim of this s...
متن کاملT cells and blood vessels: costimulation turns up the pressure.
Remarkable advances in our understanding of innate and adaptive immunity have shed light on why inflammation is centrally involved in the pathogenesis of many diseases traditionally not viewed as primarily inflammatory in nature. One key area of progress has been the discovery and study of innate immune receptors, referred to as pattern recognition receptors (PRRs), such as toll-like receptors ...
متن کاملModeling the Spatiotemporal Dynamics of Light and Heat Propagation for In Vivo Optogenetics.
Despite the increasing use of optogenetics in vivo, the effects of direct light exposure to brain tissue are understudied. Of particular concern is the potential for heat induced by prolonged optical stimulation. We demonstrate that high-intensity light, delivered through an optical fiber, is capable of elevating firing rate locally, even in the absence of opsin expression. Predicting the sever...
