  • Trypanosomes evade the immune response through antigenic variation of a surface coat containing variant surface glycoproteins (VSG). They also express invariant surface glycoproteins (ISGs), which are less well understood. Here, Macleod et al. show that ISG65 of T. brucei is a receptor for complement component 3. They provide the crystal structure of T. brucei ISG65 in complex with complement C3d and show evidence that ISG65 is involved in reducing trypanosome susceptibility to C3-mediated clearance in vivo.

  • The Cancer Genome Atlas presents an integrative genome-wide analysis of genetic alterations in 279 head and neck squamous cell carcinomas (HNSCCs), which are classified by human papillomavirus (HPV) status; alterations in EGFR, FGFR, PIK3CA and cyclin-dependent kinases are shown to represent candidate targets for therapeutic intervention in most HNSCCs.

  • In this study, Aggarwal and colleagues perform prospective sequencing of SARS-CoV-2 isolates derived from asymptomatic student screening and symptomatic testing of students and staff at the University of Cambridge. They identify important factors that contributed to within university transmission and onward spread into the wider community.

  • Ralph Baric, Vineet Menachery and colleagues characterize a SARS-like coronavirus circulating in Chinese horseshoe bats to determine its potential to infect primary human airway epithelial cells, cause disease in mice and respond to available therapeutics.

  • An annually resolved ice-core record from West Antarctica indicates that warming driven by local insolation resulting from sea-ice decline began in that region about 2,000 years before warming in East Antarctica, reconciling two alternative explanations for deglacial warming in the Southern Hemisphere.

  • We report a generic aqueous coating methodology that provides highly biocompatible surfaces. The method is inspired by prebiotic chemistry that involves the polymerization of hydrogen cyanide (HCN). The neutralization of the commercially available HCN trimer aminomalononitrile toluenesulfonate results in spontaneous polymerization that can be used to coat a wide variety of surfaces with a highly nitrogenous polymer. The non-cytotoxic coating provides excellent cell attachment and its chemistry allows the immobilization of other compounds including metals both during coating formation or by subsequent secondary immobilization reactions. This gives access to bioactive coatings including antimicrobial surfaces. Prebiotic chemistry has always been focussed on the understanding of the chemical origin of life and has remained highly fundamental research. To our knowledge this is the first application of prebiotic chemistry to material science.
