In-depth quantitative proteomics of signal pathways in BV2 microglial cell activation


ABSTRACT: Microglia become activated by disturbances in the homeostasis of their local microenvironment. While there are varying degrees of microglia activation, a pro-inflammatory reactive state induced by exposure to stimuli like LPS and IFN-γ. In this study, we identified a total of 5497 proteins in whole cell proteome and 4938 proteins for secretome of activated BV-2 mouse microglia cell line with LPS or IFN-γ using improved shotgun proteomic approach. From the differentially expressed proteins in stimulated microglia, we were able to classify pathways related immune-inflammatory response or metabolism. Moreover, we performed longitudinal quantification of secreted proteins during the detrimental activation of microglia which releases neurotoxic molecules mediated neuronal cell loss in the brain region.

The development of systematic proteomic quantification techniques in systems biology research has enabled one to perform an in-depth analysis of cellular systems. We have developed a systematic proteomic approach that encompasses the spectrum from global to targeted analysis on a single platform. We have applied this technique to an activated microglia cell system to examine changes in the intracellular and extracellular proteomes. Microglia become activated when their homeostatic microenvironme  ...[more]
