Dark exposure lowers the MMP9 activation threshold, and subsequent light stimulation to an amblyopic eye is sufficient to induce proteolysis at thalamo-cortical synapses in deprived mouse visual cortex.
Two new polymorphic structures of recombinant human alpha-synuclein fibrils show striking differences to previous structures, while familial PD mutation sites remain crucial for protofilament interaction and fibril stability.
Self-reactive thymocyte death is most efficient when peptide-presenting cells are phagocytic, and blocking phagocytosis inhibits self-reactive thymocyte death, suggesting that phagocytes play central roles during thymocyte negative selection.
Single mouse cytomegalovirus protein, m154, downmodulates surface expression of numerous targets important for NK and CD8 T cell activation by perturbing adaptor protein-1 sorting and redirecting targets to lysosomal degradation.
ATAC-seq, CRISPR/Cas9 mutagenesis, reporter and gene expression assays revealed dynamic chromatin accessibility profiles governing differential gene expression during heart vs. pharyngeal muscle fate choices in the powerful chordate model Ciona.
