Munc13 supports fusogenicity of non-docked vesicles at synapses with disrupted active zones

Authors Tan C, de Nola G, Qiao C, Imig C, Born RT, Brose N, Kaeser PS Journal eLife Citation eLife 11:e79077. Abstract Active zones consist of protein scaffolds that are tightly attached to the presynaptic plasma membrane. They dock and prime synaptic vesicles, couple them to voltage-gated Ca2+ channels, and

Generation of bright autobioluminescent bacteria by chromosomal integration of the improved lux operon ilux2

Authors Gregor C Journal Scientific Reports Citation Sci Rep. 2022 Nov 9;12(1):19039. Abstract The bacterial bioluminescence system enables the generation of light by living cells without the requirement of an external luciferin. Due to the relatively low light emission, many applications of bioluminescence imaging would benefit from an increase in
