Abstract
Microglia (MG) are resident phagocytes in the brain responsible for neuronal maintenance. The regulation of MG necroptosis is required for protecting neurons during neurodegenerative diseases. Therefore, this study proposed to elucidate the molecular mechanisms underlying microglia necroptosis during long-time apoptotic stimuli (lipopolysaccharide, LPS). The protective role of plasmalogens (PLS) was also investigated against LPS insult in MG cells (including BV2 and MG6 cell lines). LPS produced time-dependent decreases in the survival of BV2 and MG6 cells mediated by the caspase signaling pathway. Interestingly, MG death was mediated by caspase-8 and 9 signaling pathways suggesting that MG necroptosis was actively attributed to long-time LPS treatment through intrinsic and extrinsic pathways. Notably, caspase signaling was markedly inhibited in the PLS-pretreated cells; thereby, PLS were capable of maintaining the MG cell population and inhibit the MG necroptosis against the longtime of LPS administration via its antioxidant and anti-inflammatory properties.
