Tool Details

  • Tool name: RMA.Trh4 Kb KO cells
  • Tool type: Cell Lines
  • Tool sub-type: Primary
  • Parental cell line: RMA
  • Organism: Mouse
  • Tissue: Lymphatic Tissue
  • Cancer type: Mouse Leukemia
  • Disease: Cancer
  • Description: This cell line overexpresses the ER-resident ceramide synthase Trh4 (transduced by CRISPR) and lacks the H2-Kb gene. It serves as a control in helping to understanding T-cell recognition of the Trh4-derived peptide presented by the MHC class I molecule H2-Db. This peptide-epitope is a prototypic example of a neo-antigen selectively presented by cells with processing defects in the classical MHC class I (MHC-I) pathway. RMA cells have an intact processing pathway and a functional TAP peptide transporter, but overexpress the Trh4 protein and therefore can present the Trh4 peptide. Clear T cell recognition can be observed since the irrelevant MHC class I H2-Kb was knocked out.This population acts as a clear control.
