چکیده انگلیسی
The off-response of ASH neurons had been overlooked until the microfluidic devices were introduced for in vivo imaging of neuronal activity in Caenorhabditis elegans. The mechanisms of ASH off-response were completely unknown. Here we monitored ASH off-response to CuSO4 stimulation by use of microfluidic device and genetically encoded calcium indicator (GECI) - Case12. We found ASH neurons exhibited a multiphasic response to 10 mM and 50 mM CuSO4 of 30-s stimulation duration. ASH off-responding to Cu2+ had been dramatically reduced in goa-1, mod-5, trpa-1 and egl-8 mutants. Moreover, in osm-9 mutants ASH off-response was completely eliminated. Neuron-specific rescue of osm-9 in ASH neurons restored the off-response and the normal avoidance behavior in worms.
