PLA2G2A and escherichia coli infection: The incubation of INS-1E cells with E. coli in presence of EDTA caused a significant decrease of PLA2 activity, 1.5 fold, in comparison to appropriate control; BEL decreased PLA2 activity, 2.5 fold, highlighting that, following long-term E. coli infection, iPLA2 activity is mainly responsible for AA production.
