A new cell–cell communication system in Streptococcus salivarius, a human gut commensal, discriminates between close signaling molecules to specifically produce bacteriocin-based antimicrobials and disconnects it from foreign DNA acquisition.
Microbial-sensing TLRs drive responses to the microbiota, while nucleic-acid sensing TLRs control responses to endogenous ligands, revealing novel regulation of B-1a responses through integrated BCR/TLR mediated activation.
B-1 cell unresponsiveness to antigen-stimulation is overcome during infections when Toll-like receptor engagement removes negative regulators of B cell receptor signaling, thereby supporting B-1 cell differentiation to IgM-secreting plasmablasts.
Telomeric TRF1 controls the transcriptional programmes of pluripotent stem cells by recruiting PRC2 to pluripotency and differentiation genes by controlling the expression of those gene sites and the binding of TERRA RNAs to them.
Polarizing susceptibilities to recurrent bladder infection are shaped by a duality in TNFɑ-mediated inflammation dynamics upon challenge infection that is dictated by the outcome of the initial infection.
Quantitative live-cell microscopy and molecular perturbations in Drosophila and human cells reveal a crosstalk between molecular 'rulers' (Aurora B) and 'clocks' (Cdk1) that coordinates mitotic exit in space and time.
Analysis of bearded dragon model reveals a novel tooth replacement strategy that demonstrates the critical importance of epithelial patterning, cell migration, and putative stem cell functional specialization in tissue regeneration.
Human ferritin light chain (FTL) mRNA translation is regulated via its 5'-untranslated region (5'-UTR) by three mechanisms: RNA folding, iron response protein binding, and eukaryotic translation initiation factor eIF3 binding.
Lineage analysis reveals that cardiac neural crest contributes to cardiomyocytes across vertebrates and consistent with this, the neural crest gene regulatory program is reactivated upon heart regeneration in zebrafish.
Toxoplasma gondii infection leads to conversion of natural killer cells into cells resembling innate lymphoid cells, group 1, that circulate widely, disrupting current notions suggesting that these cells have distinct lineages.
The high affinity α-synuclein-monomer binder AS69 converts into a strong sub-stoichiometric inhibitor of nucleation processes upon formation of the AS69-α-synuclein complex, achieving reduced aggregation in vitro and in vivo.
Perception of vibrotactile frequency depends on the neural discharge pattern rather than the afferent type, thus requiring a reevaluation of the notion of Pacinian/non-Pacinian channels in tactile sensory system.
When landing, Pacific parrotlets exhibit stereotyped leg and wing dynamics regardless of perch diameter and texture, but foot and claw kinematics become surface-specific upon touchdown to successfully grasp the perch.
First comprehensive genetic analysis of a Myt1 family protein reveals that neurogenesis requires direct repression of non-neuronal identities by the Myt1 family protein through MuvB co-repressor complex.
Blood flow-driven shear forces guide the sequential signaling of two antagonistic paired receptors, a critical bi-facet step that first supports leukocyte docking, then initiates transmigration through endothelium.
