Acute myeloid leukemia (AML) is a type of poor prognosis hematological malignancies characterized by heterogeneous clonal expansion of myeloid progenitors. Leukemic stem cells are thought to form the majority of a cell population in minimal residual diseases (MRDs) which are resistant to current chemotherapeutic regimens and mediate disease relapse. Current therapeutic vaccine strategies have d...
Egr2 and 3 are important for maintaining immune homeostasis. Here we define a fundamental function of Egr2 and 3 operating as a checkpoint that controls the transition between clonal expansion and differentiation of effector T cells. Egr2 and 3 deficiency resulted in defective clonal expansion but hyperactivation and excessive differentiation of T cells in response to viral infection. Conversel...
Recent genetic analyses of large populations have revealed that somatic mutations in hematopoietic cells leading to clonal expansion are commonly acquired during human aging. Clonally restricted hematopoiesis is associated with an increased risk of subsequent diagnosis of myeloid or lymphoid neoplasia and increased all-cause mortality. Although myelodysplastic syndromes (MDS) are defined by cyt...
