Expression data from T-cell Acute Lymphoblastic Leukemia (T-ALL) patient-derived xenograft treated with anti-CD3 mAbs.


ABSTRACT: T-cell acute lymphoblastic leukemia is an aggressive hematological malignancy treated with chemotherapy and has a poor prognosis. In previous studies, we demonstrated that T cell receptor (TCR)-induced negative selection is highly effective in combating T-ALL in mouse models. Moreover, targeting the TCR of diagnostic T-ALL-derived PDX with anti-hCD3 (aCD3) mAb OKT3 or the clinically relevant aCD3 mAb Teplizumab resulted in leukemic cell death, regression of leukemia, and improved host survival. The objective of the present experiment is to uncover the molecular mechanisms responsible for the anti-leukemic properties of the anti-CD3 mAbs OKT3 and Teplizumab in a T-ALL PDX model. We compare the transcriptomic profiles of FACS-sorted T-ALL cells extracted from T-ALL patient-derived xenograft (PDX) treated  for 6h with  isotype control antibody IgG2a or OKT3 mAb or Teplizumab mAb.
