    Heat shock protein 70 (Hsp70) is a molecular chaperone which, by inhibiting lysosomal membrane permeabilization, promotes the survival of stressed cells. Hsp70 is now shown to stabilize lysosomes by binding to an anionic phospholipid, BMP, resulting in stimulation of acid sphingomyelinase (ASM) activity. Notably, the decreased ASM activity and lysosomal stability seen in patients with Niemann–Pick disease can be corrected by treatment with recombinant Hsp70.

    High mutation rates in the influenza A virus facilitate the generation of viral escape mutants, rendering vaccines and drugs potentially ineffective, but targeting host cell determinants could prevent viral escape. Here, 287 human host cell genes influencing influenza A virus replication are found using a genome-wide RNA interference screen. An independent assay is then used to investigate overlap between genes necessary for different viral strains.

    G-protein-coupled receptors (GPCRs) mediate the majority of cellular responses to hormones and neurotransmitters and are the largest group of therapeutic targets for a range of diseases. The extracellular surface (ECS) of GPCRs is diverse and therefore an ideal target for the discovery of subtype-selective drugs. Here, NMR spectroscopy is used to investigate ligand-specific conformational changes around a central structural feature in the ECS of a GPCR.
