Dopamine alters phage morphology to exert an anti-infection effect
Frontiers in Microbiology, 2023 Antiviral drug development is important for human health, and the emergence of novel COVID-19 variants has seriously affected human lives and safety. A bacteriophage—a bacterial virus with a small and simple structure—is an ideal experimental candidate ...

Ca2+-Stimulated Catecholamine Release from alpha-Toxin Permeabilized PC12 Cells [PDF]
, 1987 Two possible cellular pathways of catecholamines from the chromaffin vesicles of PC 12 cells to the surrounding medium are explored in this study. The direct one circumventing the cytoplasm can be activated in a-toxin-permeabilized cells with micromolar ...

Catecholamine-Mediated Increases in Gain Enhance the Precision of Cortical Representations
Journal of Neuroscience, 2016 Neurophysiological evidence suggests that neuromodulators, such as norepinephrine and dopamine, increase neural gain in target brain areas. Computational models and prominent theoretical frameworks indicate that this should enhance the precision of ...
