Here, the authors demonstrate that clinical immunity to Plasmodium vivax develops rapidly after a single controlled human malaria infection, reducing inflammatory responses and protecting against symptoms, while not significantly affecting parasite load.

The pseudokinase MLKL is activated by the upstream kinase RIPK3 in the necroptotic pathway but the structural basis of MLKL activation is not well understood yet. Here, the authors present the crystal structures of the human RIPK3:MLKL complex and human RIPK3 kinase alone, which reveal structural differences between human and murine RIPK3 and they discuss mechanistic implications.

The accumulation of alpha-synuclein fibrils within neurons is the defining feature of Lewy body dementia (LBD). Here the authors report a method to produce large quantities of alpha-synuclein fibrils that reproduce the complex structure of the fibrils that accumulate in LBD brain tissue.

How the necroptosis executioner, MLKL, converts to a killer form has been mysterious. Here, authors show RIPK3-mediated phosphorylation of human MLKL is the cue for pseudokinase domain dimerization before assembly of pro-necroptotic MLKL tetramers.

The BAM complex is assisted by periplasmic chaperones, such as SurA, in its folding and insertion of proteins into the bacterial outer membrane. Here, the authors use disulphide bond engineering to trap transient protein complexes and solve their cryoEM structures to shed light on the cycle of SurA arrival, OMP delivery, and handover to BAM.
