Description

The abstract reports that neurotoxic effects were ‘partially attenuated at higher concentrations of UV-328’ - a counterintuitive dose-response relationship. This contradicts typical toxicological expectations and suggests unknown protective mechanisms at higher doses that could inform neuroprotective strategies.
