A new giant virus that infects bacteria commonly found in the human gut has been discovered by an international team led by researchers from UCL and UC Berkeley.
A study, co-authored by Professor Joanne Santini and published in Nature Microbiology, describes the discovery of Lak phage and reports that they specifically infect bacteria called Prevotella which live in all people but most notably those who have a traditional ‘hunter gatherer’ high in fibre and low in fat.

Professor Saul Purton (SMB) has been successful in securing major funding from the BBSRC to run a UK-wide network in algal biotechnology. The award is part of a £11 million second phase investment by BBSRC and EPSRC to support 'Networks in Biotechnology and Bioenergy' (NIBB).
The six awards aim to build capacity and capability in biologically based manufacturing processes by fostering collaboration between academic researchers, industry and other stakeholders.
The algal NIBB, called 'Algae-UK' will run for five years from 2019, and builds on the tremendous success of the phase I NIBB, PHYCONET of which Saul is the Director.

Article co-authored by Matilda Katan highlights the importance of embracing virtual reality by the higher education community
Authors of the article published in the Times Higher Education in May argue that failure to engage by universities with immersive technologies presents a wasted opportunity. These innovations have the potential to enhance interactions with external stakeholders and alumni and can be employed to aid greater research and education integration.

Professor Andres Ramos (research profile) has been awarded an MRC Program grant entitled: 'Molecular mechanisms regulating mRNA transport and local translation in neurons'.
The research will investigate the crucial role played by RNA binding proteins in the regulation of the transport and translation of mRNAs in dendritic and axonal locations. The regulation of mRNA translation in space and time creates distinct local biochemical environments in the cell, which are essential in mediating inter-neuronal communication and establishing neuronal networks. This MRC programme is a collaboration between groups at ISMB, the UCL Sainsbury Wellcome Centre, the Francis Crick Institute, the UCL Institute of Neurology and the Albert Einstein College of Medicine in New York. The grant will run from 2018 to 2023.

"CHC22 Clathrin Diverts GLUT4 from the ER-to-Golgi Intermediate Compartment for Intracellular Sequestration" - new preprint by the Brodsky lab
Abstract: The Glucose Transporter 4 (GLUT4) in muscle and adipose tissue mediates post-prandial blood glucose clearance by insulin-stimulated GLUT4 translocation to the cell surface from an intracellular GLUT4 storage compartment (GSC). Deregulation of this process establishes insulin resistance and contributes to pathogenesis of type-2 diabetes (T2D). Endocytic pathways targeting GLUT4 to the GSC after insulin-mediated release have been defined extensively in rodent models. Here we map the biosynthetic trafficking pathway leading to initial GSC formation, which is less characterised, and differs between humans and rodents. In human muscle and adipocytes, GSC formation involves the non-canonical isoform of clathrin, CHC22, which does not mediate endocytosis and accumulates at sites of GLUT4 sequestration during insulin resistance. Mice have lost the CLTCL1 gene encoding CHC22, and use conventional CHC17 clathrin for GSC formation by endocytic pathways that do not replace CHC22 function in human GSC formation. Here we report that CHC22 controls GLUT4 transport from the ER-to-Golgi intermediate compartment (ERGIC) in an unconventional secretory pathway, bypassing the Golgi, to form the human GSC. This specialized route for human GLUT4 membrane traffic has relevance for understanding insulin resistance.

"CHC22 and CHC17 clathrins have distinct biochemical properties and display differential regulation and function" - new paper by the Brodsky lab
Abstract: Clathrins are cytoplasmic proteins that play essential roles in endocytosis and other membrane traffic pathways. Upon recruitment to intracellular membranes, the canonical clathrin triskelion assembles into a polyhedral protein coat that facilitates vesicle formation and captures cargo molecules for transport. The triskelion is formed by trimerization of three clathrin heavy-chain subunits. Most vertebrates have two isoforms of clathrin heavy chains, CHC17 and CHC22, generating two clathrins with distinct cellular functions. CHC17 forms vesicles at the plasma membrane for receptor-mediated endocytosis and at the trans-Golgi network for organelle biogenesis. CHC22 plays a key role in intracellular targeting of the insulin-regulated glucose transporter 4 (GLUT4), accumulates at the site of GLUT4 sequestration during insulin resistance, and has also been implicated in neuronal development. Here, we demonstrate that CHC22 and CHC17 share morphological features, in that CHC22 forms a triskelion and latticed vesicle coats. However, cellular CHC22-coated vesicles were distinct from those formed by CHC17. The CHC22 coat was more stable to pH change and was not removed by the enzyme complex that disassembles the CHC17 coat. Moreover, the two clathrins were differentially recruited to membranes by adaptors, and CHC22 did not support vesicle formation or transferrin endocytosis at the plasma membrane in the presence or absence of CHC17. Our findings provide biochemical evidence for separate regulation and distinct functional niches for CHC17 and CHC22 in human cells. Furthermore, the greater stability of the CHC22 coat relative to the CHC17 coat may be relevant to its excessive accumulation with GLUT4 during insulin resistance.

People with low iron levels may be at greater risk of heart disease, according to a new study involving UCL scientists.
Researchers analysing genetic data have uncovered a potential protective effect of iron in coronary artery disease, suggesting that having a higher iron status reduces a person’s risk of coronary artery disease (CAD), a type of cardiovascular disease (CVD) where clogged arteries reduce the amount of blood reaching the heart.
