    摘要： Compositions and methods are provided for TEMPEST (Target-Element Modification by Physical and Enduring Structural Transmutation), a method for creating durable structures in vivo in a cell-type and/or circuit specific manner via the use of insoluble polymers. TEMPEST provides a way to functionally remove cells while preserving their “shadow” for easy post-experiment detection and classification. The method of the invention are of particular interest for modifying neurons, which may be central nervous system or peripheral nervous system cells, however the approach may be applied to other cellular systems as well, either in culture system models or in animals.

    摘要： A variety of applications, systems, methods and constructs are implemented for use in connection with screening of ion-channel modulators. Consistent with one such system, drug candidates are screened to identify their effects on cell membrane ion channels and pumps. The system includes screening cells having light responsive membrane ion switches, voltage-gated ion switches and fluorescence producing voltage sensors. A chemical delivery device introduces the drug candidates to be screened. An optical delivery device activates the light responsive ion switches. An optical sensor monitors fluorescence produced by the voltage sensors. A processor processes data received from the optical sensor. A memory stores the data received from the optical sensor.

    摘要： Stimulation of target cells using light, e.g., in vivo or in vitro, is implemented using a variety of methods and devices. One example involves a vector for delivering a light-activated NpHR-based molecule comprising a nucleic acid sequence that codes for light-activated NpHR-based molecule and a promoter. Either a high expression of the molecule manifests a toxicity level that is less than about 75%, or the light-activated NpHR-based proteins are expressed using at least two NpHR-based molecular variants. Each of the variants characterized in being useful for expressing a light-activated NpHR-based molecule that responds to light by producing an inhibitory current to dissuade depolarization of the neuron. Other aspects and embodiments are directed to systems, methods, kits, compositions of matter and molecules for ion pumps or for controlling inhibitory currents in a cell (e.g., in in vivo and in vitro environments).
