Extended Data Figure 4. mLama4 and mAlg8 bind H-2K^b and stimulate CD8⁺ T cell lines generated against d42m1-T3 following αPD-1 immunotherapy.

a, IFN-γ release by CTL 62, CTL 73, or CTL 74 T cell lines following stimulation with naïve irradiated splenocytes pulsed with WT or mutant forms of Lama4 or Alg8 peptides. b, RMA-S cells were incubated with 8 amino acid peptides of mLama4 or mAlg8 and surface expression of H-2K^b or H-2D^b was assessed by flow cytometry. Mean fluorescent intensity of H-2K^b and H-2D^b was expressed as peptide binding score. Data presented are representative of at least two independent experiments.
