The current study investigated whether ethanol alters ATP activation of purinergic type 2 receptors (P2Rs) in the ventral tegmental area (VTA). The VTA is a key region of the brain that has been implicated in the development of alcohol addiction. We investigated the effects of ATP and ethanol on spontaneous inhibitory postsynaptic currents (sIPSCs) and the spontaneous firings in the VTA dopaminergic neurons, obtained using an enzyme-free procedure. These neurons preserved some functional GABA-releasing terminals after isolation.

Fibroblasts in whole areolar connective tissue respond to static stretching of the tissue by expanding and remodeling their cytoskeleton within minutes both ex vivo and in vivo. This study tested the hypothesis that the mechanism of fibroblast expansion in response to tissue stretch involves extracellular ATP signaling. In response to tissue stretch ex vivo, ATP levels in the bath solution increased significantly, and this increase was sustained for 20 min, returning to baseline at 60 min.
