An Atypical Kappa‐Class Chaperone‐Usher Fimbriae of a Human Enterotoxigenic Escherichia coli Strain Shows Multi‐Host Adherence and Distinct Phylogenetic Feature

Microbiology and Immunology, EarlyView.
ABSTRACT The pathogenesis of enterotoxigenic Escherichia coli (ETEC) involves the colonization of hosts by colonization factors (CFs) and the secretion of enterotoxins. CFs, especially chaperone‐usher fimbriae, mediate bacterial adhesion to host cells, with extensive genetic diversity observed among isolates.

Weakened Airway Epithelial Junctions and Enhanced Neutrophil Elastase Release Contribute to Age‐Dependent Bacteremia Risk Following Pneumococcal Pneumonia

Aging Cell, EarlyView.
During spread of Streptococcus pneumoniae from the lung to the bloodstream, the pneumococcal pore‐forming toxin pneumolysin (PLY) disrupts apical junction complexes (AJCs) and triggers the transmigration of polymorphonuclear leukocytes (PMNs), which secrete tissue‐destructive neutrophil elastase.

Identification of new flagellin-encoding fliC genes in Escherichia coli isolated from domestic animals using RFLP-PCR and sequencing methods Identificação de novas flagelinas codificadas por fliC em Escherichia coli isoladas de animais domésticos utilizando RFLP-PCR e sequenciamento

Pesquisa Veterinária Brasileira, 2013
Identification of Escherichia coli requires knowledge regarding the prevalent serotypes and virulence factors profiles allows the classification in pathogenic/non-pathogenic. However, some of these bacteria do not express flagellar antigen invitro.

Astrocytic Hevin/SPARCL‐1 Regulates Cognitive Decline in Pathological and Normal Brain Aging

Aging Cell, EarlyView.
Hevin/Sparcl‐1 is a synaptogenic protein secreted by astrocytes. We used adeno‐associated virus (AAV) to increase its expression in hippocampal astrocytes of APP/PSEN1 mice, an animal model for Alzheimer's disease (AD). This procedure improved cognitive performance both in the AD model and in middle‐aged wild‐type animals.

Reduction of DNA Topoisomerase Top2 Reprograms the Epigenetic Landscape and Extends Health and Life Span Across Species

Aging Cell, EarlyView.
This study demonstrates that reducing the enzyme topoisomerase Top2 or its mammalian homolog TOP2B promotes longevity across multiple species, including yeast, worms, and mice. At the cellular/molecular level, TOP2B reduction mitigates the major cellular aging hallmarks such as epigenetic alterations, cell senescence, lysosomal biogenesis, and ...

Senescent Macrophages Promote Age‐Related Revascularization Impairment by Increasing Antiangiogenic VEGF‐A165B Expression

Aging Cell, EarlyView.
The underlying mechanisms of age‐related revascularization impairment are not clear. Our research firstly identified that macrophages were more senescent in the ischemic skeletal muscle of old mice and senescent macrophages could inhibit revascularization.
