Proteome analysis of Corynebacterium diphtheriae - macrophage interaction

Contact of Corynebacterium diphtheriae with macrophages induce adaptations on both bacterial and cellular sides. Using an experimental design involving gentamicin protection and liquid chromagraphy followed by mass-spectrometry, a multi-species proteomic dataset was analyzed at different time points of the infection assay. Several previously undescribed Corynebacterium proteins were differentially regulated, as well as key macrophage components of the phagolysosome. Overall, Bacteria responded to phagocytosis by changes in DNA repair, transcription and cell wall synthesis proteins, while macrophages showed changes in components of the innate immune system. This dataset consists of: Raw protein abundance data for Macrophage THP-1 cells (M0) obtained by LC-MS/MS followed by peptide sequencing using Proteome Discoverer (ThermoFisher) -see .zip folder. Raw protein abundance data for Macrophage C. diphtheriae ISS3319 (CD) obtained by LC-MS/MS followed by peptide sequencing using Proteome Discoverer (ThermoFisher) - see .zip folder. Differential protein abundance analysis for CD and M0 using LIMMA. Data underlying the growth curves observed in CD in RPMI + 10% FBS conditions (infection assay conditions).
