Exploratory experiment designed to discover new patterns targeting AMPK, mTOR, GFAP, SQSTM1, LC3 in in vitro ICH cell culture model with astrocytes. Primary outcome: astrocyte protection from autophagy
This in vitro experiment investigated the direct effects of iPSC-NPCs on astrocytes using an ICH cell culture model. The study examined how iPSC-NPCs influence astrocyte autophagy and activation through the AMPK/mTOR signaling pathway. Researchers analyzed protein and mRNA expression changes of key autophagy markers including GFAP, AMPK, mTOR, SQSTM1/P62, and LC3 using immunofluorescence techniques. The experiment demonstrated that iPSC-NPCs secrete cytokines that protect astrocytes from autophagy by inhibiting AMPK phosphorylation and promoting mTOR activation. The study also included pharmacological validation using mTOR inhibitors to confirm the pathway involvement.
