Cancer is a heterogeneous disease with myriad causes and outcomes. Many of the cancers that occur in adult populations have become increasingly well characterized with the advent of affordable high-throughput sequencing. These studies have revealed that cancer is largely a disease of somatic mutation in the adult population. In strong contrast to this, childhood cancers have an exceedingly low rate of somatic mutation. At the extreme end of this spectrum is Infant Leukemia (IL). Sequencing of IL has revealed that these tumors frequently have one or fewer somatic SNP. In the absence of a somatic explanation for IL, many other …

Innate lymphoid cells (ILCs) are a recently discovered lineage of professional cytokine-producing cells that strikingly mirror T cells in transcriptional circuitry and effector functions, but derive from distinct progenitors and do not express recombined antigen-specific receptors. These cells include natural killer (NK) cells, which parallel cytotoxic CD8+ T cells, and three additional classes of ILCs enriched at mucosal surfaces that generate signature cytokines reminiscent of polarized CD4+ helper T cells subsets, called ILC1, ILC2, and ILC3. As ILCs have been implicated in the pathogenesis of colitis, cancer, allergy, and autoimmunity in both human and mouse, understanding the functional capacity of …
