A novel pathway was discovered for cellular uptake of LPS through secretory protein secretoglobin3A2 and a receptor syndecan-1, causing activation of non-canonical inflammasome pathway leading to pyroptosis of cancer cells.
Heterochromatin formation at transposon loci depends on dimerisation of the effector complex that elicits co-transcriptional silencing and this requirement is fulfilled by co-option of the conserved dimerisation hub protein, Cut-up/LC8.
Phylogenomics provides support for the Gram-positive type of bacterial cell envelope being a derived character that arose independently multiple times through loss of an ancestral outer membrane.
A novel synthetic DNA cassette of CTCF-binding sites combined with the drug-controllable induction system of heterochromatin enabled switchable blocking of chromatin conformation and gene-enhancer interaction.
Population cortical recordings and computational network modeling support a novel mechanism underlying spontaneous UP-DOWN dynamics consisting on non-rhythmic transitions between a silent attractor and a low-rate inhibition-stabilized attractor.
RNA virus replication is attenuated by an intrinsic restriction mechanism after introducing CpG/UpA dinucleotides into both non-translated and coding regions of viral genomes, which may be exploited in the design of attenuated virus vaccines.
Attenuating candidate live virus vaccines by incorporating unfavoured codon pairs to reduce translation efficiency is actually mediated though changes in frequencies of CpG and UpA dinucleotides, which make viruses more visible to the innate immune system.
Lymphocytes and monocytes maintain their cell surface HLA-B via different mechanisms, which in turn differently influence cell-surface expression, half-life and peptide receptivity of HLA-B allotypes.
