While we found a clear CD1d dependent overrepresentation of Vβ7-specific NK1.1+ T cells in TCL1 mice, we did not observe Vβ7 skewing despite of CD1d downregulation on leukemic cells in our tumor-transplant system, although a general T cell skewing towards effector-memory T cells was recently reported upon transplanting TCL1 tumors into wildtype recipients [16]. Here, CD1D is linked to neoplasm.
