Idiosyncratic Mòjiāng virus attachment glycoprotein directs a host-cell entry pathway distinct from genetically related henipaviruses OPEN
Ilona Rissanen, Asim A. Ahmed, Kristopher Azarm, Shannon Beaty, Patrick Hong, Sham Nambulli, W. Paul Duprex, Benhur Lee and Thomas A. Bowden
The attachment glycoprotein (HNV-G) of henipaviruses interacts with host receptors at the cell surface and is a major determinant of species tropism. Here the authors provide structural and functional evidence that the emergent henipavirus, Mòjiang virus, uses an entry mechanism that is independent of known paramyoxviral cellular receptors.

LFA-1 activates focal adhesion kinases FAK1/PYK2 to generate LAT-GRB2-SKAP1 complexes that terminate T-cell conjugate formation OPEN
Monika Raab, Yuning Lu, Karsten Kohler, Xin Smith, Klaus Strebhardt and Christopher E. Rudd
The T-cell integrin LFA-1 binds ICAM-1 on antigen presenting cells to affect TCR-MHC interactions. Here the authors show detailed mechanics of how LFA-1 ligation affects T-cell conjugation to dendritic cells to regulate adhesion and de-adhesion of these cells in the context of antigen presentation.
12 July 2017 | doi: 10.1038/ncomms16001

Anion-capped metallohost allows extremely slow guest uptake and on-demand acceleration of guest exchange OPEN
Yoko Sakata, Chiho Murata and Shigehisa Akine
Host—guest assemblies can exploit stimuli-responsive guest binding and release for molecular recognition, but are typically governed by thermodynamics alone. Here, the authors design macrocycles with removable and exchangeable anion caps, allowing for the kinetic trapping and on-demand exchange of guest ions.
12 July 2017 | doi: 10.1038/ncomms16005

Adipocyte adaptive immunity mediates diet-induced adipose inflammation and insulin resistance by decreasing adipose Treg cells OPEN
