The lateral line is a mechanosensory system used by fish to sense the movement of water. It is evolutionarily related to the inner-ear in humans. For both organisms, the binding of the CXCL12 (SDF-1 ligand) to the CXCR4 receptor induces conformational changes needed to activate signal transduction. This signaling results in numerous cellular responses such as cell fate, chemotaxis, and gene transcription. Interestingly, researchers have found that another signaling molecule, CXCL14, can also bind to the CXCR4 receptor with high affinity (Tanegashima et al., 2013). As a result, we hypothesize that CXCL14 modulates CXCL12-mediated chemotaxis, presumably acting as an allosteric …

Inversion of chromosome 16 [inv(16)] acute myeloid leukemia (AML) generates a fusion gene CBFB-MYH11. Approximately half of inv(16) AML patients eventually relapse mainly due to the existence of leukemia stem cells (LSCs). Previous work using a Cbfb-MYH11 knockin mouse model showed that the LSCs are enriched within CSF2RB- population. Another gene upregulated by Cbfb-MYH11 encodes the cytokine receptor IL1RL1. Using Cbfb-MYH11 knockin mice, we showed that LSCs exist in multiple sub-populations defined by their immunophenotype, and IL1RL1 is expressed by cell populations with high LSC activity. We also found that treatment of IL-33, the ligand for IL1RL1, promoted …
