Neural engineering with photons as synaptic transmitters.

Neuronal computation is achieved through connections of individual neurons into a larger network. To expand the repertoire of endogenous cellular communication, we developed a synthetic, photon-assisted synaptic transmission (PhAST) system. PhAST is based on luciferases and channelrhodopsins that enable the transmission of a neuronal state across space, using photons as neurotransmitters.

FLInt: single shot safe harbor transgene integration via Fluorescent Landmark Interference.

The stable incorporation of transgenes and recombinant DNA material into the host genome is a bottleneck in many bioengineering applications. Due to the low efficiency, identifying the transgenic animals is often a needle in the haystack. Thus, optimal conditions require efficient screening procedures, but also known and safe landing sites that do not interfere with host expression, low input material and strong expression from the new locus.

Neuroprotective effects of a medium chain fatty acid, decanoic acid, isolated from against Parkinsonism in PD model.

Sea cucumbers are marine organism that have long been used for food and traditional medicine in Asian countries. Recently, we have shown that ethyl acetate fraction (HLEA) of the crude extract of the black sea cucumber, could alleviate Parkinsonism in PD models. In this study, we found that the effective neuroprotective activity is attributed to HLEA-P1 compound chemically isolated and identified in ethyl acetate.

An asymmetric mechanical code ciphers curvature-dependent proprioceptor activity.

A repetitive gait cycle is an archetypical component within the behavioral repertoire of many animals including humans. It originates from mechanical feedback within proprioceptors to adjust the motor program during locomotion and thus leads to a periodic orbit in a low-dimensional space. Here, we investigate the mechanics, molecules, and neurons responsible for proprioception in Caenorhabditis elegans to gain insight into how mechanosensation shapes the orbital trajectory to a well-defined limit cycle.

Diterpene glycosides from Holothuria scabra exert the α-synuclein degradation and neuroprotection against α-synuclein-Mediated neurodegeneration in C. elegans model.

Ethnopharmacological Relevance: Holothuria (Metriatyla) scabra Jaeger (H. scabra), sea cucumber, is the marine organism that has been used as traditional food and medicine to gain the health benefits since ancient time. Although our recent studies have shown that crude extracts from H.

Anti-Parkinson activity of bioactive substances extracted from Holothuria leucospilota.

Parkinson's disease (PD) is a well-known neurodegenerative disorder characterized by dopaminergic (DA) neuron loss and α-synuclein aggregation. Recent study revealed that the extracts from sea cucumber, Holothuroidea spp., exhibited neuroprotective and lifespan extension effects in Caenorhabditis elegans model.
