MTOR and neuroblastoma: Moreover, the present results showed an increase in the mTOR protein expression after the treatment of the U-87MG cells with AgNPs, which is consistent with the results reported in the literature inter alia by Li et al. in neuroblastoma cells (SH-SY5Y) or by Chang et al. in mouse hippocampal neurons (HT-22), suggesting the potential of the tested AgNPs to induce autophagy (Li et al. 2019; Chang et al. 2021).
