NIR‐Induced Photoswitching Hybrid DNA Nanoconstruct‐Based Drug Delivery System for Spatiotemporal Control of Stem Cell Fate

open access: yesSmall, EarlyView.
NIR‐mediated photo‐switching drug delivery system for the remote‐control differentiation of NSCs. Left: NIR‐mediated curcumin release is induced by NIR‐to‐UV photon upconversion in a photo‐controllable manner. Curcumin is bound in the minor groove of the synthesized DNA construct containing AAP photo‐switchers. Right: The rational design of several AAP

Optogenetic Evocation of Field Inhibitory Postsynaptic Potentials in Hippocampal Slices: A Simple and Reliable Approach for Studying Pharmacological Effects on GABAA and GABAB Receptor-Mediated Neurotransmission

open access: yesFrontiers in Cellular Neuroscience, 2014
The GABAergic system is the main source of inhibition in the mammalian brain. Consequently, much effort is still made to develop new modulators of GABAergic synaptic transmission.

Longitudinal Optogenetic Motor Mapping Revealed Structural and Functional Impairments and Enhanced Corticorubral Projection after Contusive Spinal Cord Injury in Mice [PDF]

open access: yes, 2019
Current evaluation of impairment and repair after spinal cord injury (SCI) is largely dependent on behavioral assessment and histological analysis of injured tissue and pathways. Here, we evaluated whether transcranial optogenetic mapping of motor cortex

Yellow Optogenetics with Volvox Channelrhodopsin Variants [PDF]

open access: yesBiophysical Journal, 2012
Channelrhodopsins (ChR) are light-gated ion channels and rhodopsins with internal ion conducting pores. In 2001 ChR1 and ChR2 cDNAs were identified in Chlamydomonas reinhardtii data bases. The isomerization of the all-trans-retinal chromophore induces conformational changes of the protein that result in the opening of the channel pore to allow ion flow

Graph‐based algorithms to dissect long‐distance water‐mediated H‐bond networks for conformational couplings in GPCRs

open access: yesBritish Journal of Pharmacology, EarlyView.
Graph‐based algorithms that enable efficient computations of all H‐bonds present in structures in entire datasets allow us to dissect H‐bond fingerprints that characterize distinct GPCRs and the structures sampled along their activation. Abstract Changes in structure and dynamics elicited by agonist ligand binding at the extracellular side of G protein

Machine learning-guided directed evolution for protein engineering [PDF]

open access: yes, 2019
Machine learning (ML)-guided directed evolution is a new paradigm for biological design that enables optimization of complex functions. ML methods use data to predict how sequence maps to function without requiring a detailed model of the underlying ...

CAV-2 Vector Development and Gene Transfer in the Central and Peripheral Nervous Systems [PDF]

open access: yes, 2019
The options available for genetic modification of cells of the central nervous system (CNS) have greatly increased in the last decade. The current panoply of viral and nonviral vectors provides multifunctional platforms to deliver expression cassettes to

Chronic optogenetic stimulation of dentate gyrus granule cells in mouse organotypic slice cultures synaptically drives mossy cell degeneration

open access: yesEpilepsia, EarlyView.
Abstract Objective Degeneration of hilar mossy cells in the dentate gyrus is an important hallmark of hippocampal sclerosis and is often observed in patients with temporal lobe epilepsy. To understand the pathogenesis of hippocampal sclerosis and develop novel neuroprotective treatments, it is critical to determine the mechanistic processes of mossy ...
