SOS System Induction Inhibits the Assembly of Chemoreceptor Signaling Clusters in Salmonella enterica. [PDF]
PLoS ONE, 2016 Swarming, a flagellar-driven multicellular form of motility, is associated with bacterial virulence and increased antibiotic resistance. In this work we demonstrate that activation of the SOS response reversibly inhibits swarming motility by preventing ...

HilD-regulated chemotaxis proteins contribute to Salmonella Typhimurium colonization in the gut [PDF]
mBioIn the enteric pathogen Salmonella Typhimurium, invasion and motility are coordinated by HilD, a master regulator that activates expression of genes encoding the type III secretion system 1 and some motility genes, including the chemotaxis gene mcpC ...

Type II Cells in the Human Carotid Body Display P2X7 Receptor and Pannexin-1 Immunoreactivity [PDF]
BiomoleculesThe carotid body is a peripheral chemoreceptor that consists of clusters of chemoreceptive type I cells, glia-like type II cells, afferent and efferent nerves, and sinusoidal capillaries and arterioles.

Reactive Oxidative Species in Carotid Body Chemoreception: Their Role in Oxygen Sensing and Cardiorespiratory Alterations Induced by Chronic Intermittent Hypoxia [PDF]
AntioxidantsThe carotid body (CB) senses arterial PO2, PCO2, and pH levels, eliciting reflex responses to maintain cardiorespiratory homeostasis. Chronic intermittent hypoxia (CIH), the hallmark of obstructive sleep apnea, elicits autonomic and cardiorespiratory ...

Protein connectivity in chemotaxis receptor complexes [PDF]
, 2015 The chemotaxis sensory system allows bacteria such as Escherichia coli to swim towards nutrients and away from repellents. The underlying pathway is remarkably sensitive in detecting chemical gradients over a wide range of ambient concentrations ...

Vascular control of the CO2/H+-dependent drive to breathe
eLife, 2020 Respiratory chemoreceptors regulate breathing in response to changes in tissue CO2/H+. Blood flow is a fundamental determinant of tissue CO2/H+, yet little is known regarding how regulation of vascular tone in chemoreceptor regions contributes to ...
