Title: MHC1-TIP: scalable multimodal immunopeptidome profiling of low-input samples
Submitter: Rik Lindeboom
LabHead: Rik Gerrit Hendrik Lindeboom
Description: We developed MHC1-TIP: an optimized mild acid elution-based immunopeptidomics workflow that leverages data independent acquisition and the Astral mass analyzer to enable scalable, single-tube and cost-effective MHC-I ligandome profiling. This dataset includes immunopeptidomics and proteomics data from the A375 melanoma cell line, colorectal cancer patient-derived organoids, and renal cell carcinoma tumour fragments. We show the effects of TGF-beta treatment on the proteome and immunopeptidome of A375 cells and interferon-gamma treatment on patient-derived organoids. We also explore immunopeptidome and proteome heterogeneity in patient-derived tumour fragments. MB_30: A375 immunopeptidomes in DDA (wildtype and B2M knockout); MB_38: Proteomes with and without mild acid treatment with A375 cells; MB_39: Proteomes and immunopeptidomes from TGFb treated A375 cells; MB_41: MHC1-TIP and MHC-I immunoprecipitation data from different A375 cell input numbers; MB_43: immunopeptido
mes of A375 cells treated with different doses of interferon-gamma; MB_45: immunopeptidomes of A375 cells with MHC1-TIP and immunoprecipitation after mild acid elution to identify intracellular peptides; MB_46: Proteomics and immunopeptidomics data from 15 ex-vivo cultured patient-derived tumour fragments; MB_49: Proteomics and immunopeptidomics data from 3 patient-derived organoid lines.
