    Components of the spliceosome are frequently mutated in haematopoietic malignancies. Identification of mis-spliced genes promoting transformation will uncover novel targeted therapies. Now, a long isoform of IRAK4 is shown to be upregulated in a subset of acute myeloid leukaemia patients, conferring susceptibility for IRAK4 inhibition therapy.

    Rag GTPases play a crucial role in mTORC1 activation by promoting its recruitment to the lysosomal surface in a nutrient-dependent manner. A study now identifies a family of lysosomal G-protein-coupled receptors as modulators of Rag GTPases localization and activation, adding one more component to the fast-growing mTOR regulatory network.

    Haematopoietic stem cells (HSCs) are maintained in vivo by intrinsic programs and extrinsic niche signals. Ex vivo expansion of HSCs is limited, owing to reduced stem cell maintenance factors. A study now shows that rejuvenated niche cells can be obtained by transcriptional rewiring of specific genes that maintain and expand HSCs ex vivo.
