The COP9 signalosome reduces neuroinflammation and attenuates ischemic neuronal stress in organotypic brain slice culture model Version 1
External LinkIn the context of studying the role of the COP9 signalosome (CSN) in neuroinflammation and ischemic neuronal damage, we studied the effect of the cullin NEDDylation state-modifying drugs MLN4924 and CSN5i-3 in BV2 microglial cells, an immortalized murine cell line featuring many of the characteristics of primary microglia. Owing to its potent inhibitory effect on the NEDDylation cascade, MLN4924 exhibits a CSN5-like anti-inflammatory activity. Csn5i-3 is a small molecule inhibitor that specifically binds to CSN5, while it resides in the CSN holocomplex and blocks its deNEDDylase activity, thus leading to an accumulation of NEDDylated cullins. We performed untargeted mass spectrometry-based proteomics of the cell lysates after treating BV2 cells with these drugs under basal culture stress conditions. The proteomic analysis revealed that MLN4924 and CSN5i-3 substantially altered the microglial proteome.

BV2 cells were cultured in full medium in 10 cm cell culture dishes until they were confluent. MLN4924 (500 nM), CSN5i-3 (1 μM), or solvent control (0.01% DMSO) were added and the culturing continued for 6 h. After the incubation, cells were washed once with PBS, removed from the cell culture plate with a scraper, collected in tubes, and centrifuged in 1.5 ml Eppendorf tubes for 3 min to remove remaining PBS buffer, snap-frozen, and stored at -80 °C until further processing. Thereafter cells were ...
