Several viral infections, and the progression of virus-induced diseases, especially those associated with COVID-19, are characterized by an alteration in the intracellular redox balance (144, 145) and respiratory diseases, known risk factors for developing severe illness and death in patients with SARS-CoV-2 and COVID-19 disease

In line with previous results obtained in rodent neuronal cultures 43 , we found that the administration of lactate in a concentration range of 520 mM (which are relatively high as compared to physiological ones 19 ) caused an immediate drop in the electrophysiological activity of hiPSCs-derived neuronal networks, in a concentration-dependent manner
