Quantitative proteomic changes in LPS-activated monocyte-derived dendritic cells: A SWATH-MS study.

ABSTRACT: Dendritic cells are key immune cells that respond to pathogens and co-ordinate many innate and adaptive immune responses. Quantitative mass spectrometry using Sequential Window Acquisition of all THeoretical fragment-ion spectra-Mass Spectrometry (SWATH-MS) was performed here to determine the global alterations in monocyte-derived dendritic cells (moDCs) in response to stimulation with lipopolysaccharide (LPS). A moDC library of 4,666 proteins was generated and proteins were quantified at 0, 6 and 24 h post-LPS stimulation using SWATH-MS. At 6 h and 24 h post-LPS exposure, the relative abundance of 227 and 282 proteins was statistically significantly altered (p-value ≤ 0.05), respectively. Functional annotation of proteins exhibiting significant changes in expression between the various ti
