Title	MHC I-restricted immunopeptidomics analysis of human monocyte-derived macrophages exposed to biological nanoparticles bearing influenza hemagglutinin
Description	In this study, primary human monocyte-derived macrophages were exposed to plant-derived virus-like particles (VLPs) bearing influenza A hemagglutinin (HA) or soluble influenza HA, as control. Immunopurified MHC class I-associated peptides were analysed by nano-flow high pressure liquid chromatography coupled to high-resolution dopant-assisted electrospray ionisation mass spectrometry. A total of 109 host-derived MHC I peptides were identified in the VLP-treated samples, two of which were also detected in controls. The peptides unique to VLP treatment were, on average, ~13 amino acid residues long, more basic and hydrophilic, and were mainly processed via proteolysis by matrix metalloproteinases and cathepsins. The proteins associated with these peptides were primarily involved in cellular, metabolic and regulatory processes and activated several pathways including inflammation stimulation and attenuation, response to stimuli, innate and adaptive immunity, clathrin-mediated endocytosis, protein synthesis and endo-lysosomal degradation. This study is the first report to describe the response of a primary human antigen-presenting cell to nanoparticulate vs. soluble antigen exposure from an immunopeptidomics point of view.
