Previously, we identified a therapy-resistant role of IL-34 in an immune checkpoint blockade in murine models. To investigate whether a similar mechanism is applicable in human tumors as well, we used this protocol for the selection of IL-34-neutralizing antibody and transplanting human tumor tissue expressing both IL-34 and PD-L1 as a patient-derived xenograft in immunologically humanized mice. This model helps to determine the effect of IL-34 neutralization along with the immune checkpoint blockade in human tumors. For complete details on the use and execution of this protocol, please refer to Hama et al. (2020).
