Epitopes derived from two regions of α-synuclein elicit immune responses in patients with Parkinson’s disease, involving IL-5-secreting CD4+ T cells, as well as IFNγ-secreting CD8+ cytotoxic T cells.
The crystal structure of the bacterial potassium import complex KdpFABC shows how ATP hydrolysis is coupled to potassium transport to maintain cellular homeostasis under low potassium conditions.
The authors devise an algorithm that can cluster T cell receptor (TCR) sequences sharing the same specificity, predict the HLA restriction of these TCR clusters on the basis of subjects’ genotypes and help to identify specific peptide major histocompatibility complex ligands.
The authors characterize epitope-specific T cell repertoires, identify shared and recognizable features of TCRs, and develop tools to classify antigen specificity on the basis of sequence analysis.
The poxvirus vaccinia virus phosphorylates serine/threonine residues in the human small ribosomal subunit RACK1, converting it to a plant-like state to favour translation of poxvirus mRNAs
Phosphorylation or DNA binding promotes the physical partitioning of HP1α out of a soluble aqueous phase into droplets, suggesting that the repressive action of heterochromatin may in part be mediated by the phase separation of HP1.
The inflammasome receptor Nlrp9b defends against enteric viruses by interacting with double-stranded viral RNA-bound helicase Dhx9, triggering gasdermin-D-dependent pyroptotic cell death of infected cells and secretion of Il-18.
Analysis of a comprehensive database of mammalian host–virus relationships reveals that both the total number of viruses that infect a given species and the proportion likely to be zoonotic are predictable and that this enables identification of mammalian species and geographic locations where novel zoonoses are likely to be found.
A new type of fermion, corresponding to a three-fold degeneracy in the electronic band structure of crystalline molybdenum phosphide, is observed, which lies conceptually between Dirac and Weyl fermions.
The suction cups found in octopus tentacles are the inspiration for a synthetic adhesive that functions well in dry and wet conditions and is resistant to chemical contamination.
Molecular dynamics simulations of the Pb(Mg1/3,Nb2/3)O3–PbTiO3 relaxor reveal a multi-domain state analogous to the slush state of water that provides an explanation for the unusual properties of relaxors.
Through drug exposure, a rare, transient transcriptional program characterized by high levels of expression of known resistance drivers can get ‘burned in’, leading to the selection of cells endowed with a transcriptional drug resistance and thus more chemoresistant cancers.
A nonlinear parity–time-symmetric circuit is used to enable robust wireless power transfer to a moving device over a distance of one metre without the need for tuning.
Abnormal behavioural phenotypes and synapse loss in the brain of lupus-prone mice are prevented by blocking type I interferon signalling, which is further shown to stimulate microglial phagocytosis of neuronal material in the brains of these mice.
Both F17-like and type 1 pili promote intestinal colonization in mouse colonic crypts, and the high-affinity mannoside M4284 reduces intestinal colonization of uropathogenic Escherichia coli while simultaneously treating urinary tract infections without disrupting the composition of the gut microbiota.
Prenatal immune suppression is regulated by fetal arginase-2-expressing dendritic cells which respond normally to toll-like receptor stimulation but, in contrast to adult dendritic cells, induce regulatory T cells and repress TNF-α secretion by effector T cells.
A combination of microprism-based cellular imaging to monitor insular cortex visual cue responses in behaving mice across hunger states with circuit mapping and manipulations reveals a neural basis for state-specific biased processing of motivationally relevant cues.
PTEN, a known tumour suppressor, inhibits the FXBL2-dependent degradation of IP3R3, an IP3 receptor, thus augmenting IP3R3-mediated calcium release from the endoplasmic reticulum to mitochondria and inducing apoptosis; inhibiting FXBL2 sensitizes PTEN-deficient tumours to photodynamic therapy.
