The autonomic nervous system maintains homeostasis of cardiovascular, respiratory, gastrointestinal, urinary, immune, and thermoregulatory function. Homeostasis involves a variety of feedback mechanisms involving peripheral afferents, many of which contain molecular receptors sensitive to mechanical deformation, termed mechanosensors. Here, we focus on the molecular identity of mechanosensors involved in the baroreflex control of the cardiovascular system.

BMC Microbiol

June 2020

Department of Plant Pathology, 1991 Upper Buford Circle, University of Minnesota, St. Paul, MN, 55108, USA.

Background: Though many plant defensins exhibit antibacterial activity, little is known about their antibacterial mode of action (MOA). Antimicrobial peptides with a characterized MOA induce the expression of multiple bacterial outer membrane modifications, which are required for resistance to these membrane-targeting peptides. Mini-Tn5-lux mutant strains of Pseudomonas aeruginosa with Tn insertions disrupting outer membrane protective modifications were assessed for sensitivity against plant defensin peptides.

Institute of Cardiovascular Disease, Key Laboratory for Arteriosclerology of Hunan Province, Medical Research Experiment Center, Hunan Province Cooperative Innovation Center for Molecular Target New Drug Study, University of South China, Hengyang, Hunan 421001, China. Electronic address:

Recent studies showed that coiled-coil domain-containing 80 (CCDC80) has a positive link with atherosclerosis and that plasma CCDC80 levels are positively correlated with the levels of fasting plasma triglycerides (TG) in obese individuals. The underlying mechanisms, however, are unclear. Using Hematoxylin-eosin (H&E) and Oil Red O staining, we found that CCDC80 overexpression in vivo significantly increased plasma lipid contents, decreased the expression and activity of lipoprotein lipase (LPL), and accelerated the development of atherosclerosis.

Calmodulin (CaM) is an important signaling molecule that regulates a vast array of cellular functions by activating second messengers involved in cell function and plasticity. Low voltage-activated calcium channels of the Cav3 family have the important role of mediating low threshold calcium influx, but were not believed to interact with CaM. We find a constitutive association between CaM and the Cav3.

Background: The explosion in the use of genetically modified mouse strains to investigate function in biology has an enormous potential to expand on pharmacological studies traditionally conducted in rats. A key limitation to date is the inability to record from multiple nerves in an anaesthetised mouse for long periods.

New Method: Here we describe an in vivo preparation that maintains mice in a suitable physiological state, under anaesthesia, for at least 6 hr and also enables multiple cardiorespiratory recordings over that time.

The electrical output of neurons relies critically on voltage- and calcium-gated ion channels. The traditional view of ion channels is that they operate independently of each other in the plasma membrane in a manner that could be predicted according to biophysical characteristics of the isolated current. However, there is increasing evidence that channels interact with each other not just functionally but also physically.

Faculty of Medicine, University of Calgary, 3330 Hospital Dr. N.W, Calgary, AB, T2N 4N1, Canada,

Although the development of collaborative relationships is considered a requirement for medical education, the functioning of these relationships may be impaired by a well-documented social-psychological phenomenon known as group conformity. The authors hypothesized that students would insert a needle into an incorrect location relative to the patella when performing a knee arthrocentesis if they believed that their peers had also inserted a needle in the same incorrect location. This was a randomized controlled study conducted in 2011 with 60 medical students (24 male; 40.

Larger cortical motor maps after seizures.

Eur J Neurosci

August 2011

Hotchkiss Brain Institute, University of Calgary, 3330 Hospital Dr. N.W. Calgary, Alberta, Canada.

Expansion of motor maps occurs in both clinical populations with epilepsy and in experimental models of epilepsy when the frontal lobes are involved. We have previously shown that the forelimb area of the motor cortex undergoes extensive enlargement after seizures, although the extent to which many movement representation areas are altered is not clear. Here we hypothesize that movement representations in addition to the forelimb area will be enlarged after cortical seizures.

Mechanistic basis of differential conduction in skeletal muscle arteries.

J Physiol

March 2009

Smooth Muscle Research Group, HMRB-G86, Heritage Medical Research Building, University of Calgary, 3330 Hospital Dr. N.W., Calgary, Alberta, Canada, T2N-4N1.

The goal of this investigation was to probe intercellular conduction in skeletal muscle feed arteries and to address why smooth muscle-initiated responses fail to robustly spread like their endothelial counterpart. Using computational and experimental approaches, two interrelated rationales were developed to explain this apparent discrepancy in cell-to-cell communication. The first rationale stressed that smooth muscle electrical responses, if initiated, will be actively dissipated as they spread from cell-to-cell along the arterial wall.

Challenges to the use of autoantibodies as predictors of disease onset, diagnosis and outcomes.

Autoimmun Rev

September 2008

Department of Medicine, Faculty of Medicine, University of Calgary, 3330 Hospital Dr N.W., Calgary, AB, Canada T2N 4N1.

Autoantibodies (AA) are a serological hallmark of most autoimmune diseases. In contrast to genetic markers that show a predisposition for disease development, certain AA serve as diagnostic biomarkers and classification criteria for a number of these conditions. The role of AA is still not clearly understood: some are pathogenic, some disease specific and others serve as predictors of disease outcome, but little is known about those that protect against disease or serve as signatures of the inciting agent of autoimmunity.

Mol Cell Biochem

October 2008

McCaig Institute for Bone and Joint Health, University of Calgary, 3330 Hospital Dr. N.W., Calgary, AB, Canada, T2N 4N1.

To investigate the molecular aspects of osteoblastic interactions with a type I collagen matrix, human osteoblast-like MG-63 cells were cultured in three-dimensional (3D) collagen I gels. MG-63 cells in collagen gels expressed higher osteocalcin mRNA levels than cells in monolayer (2D) on polystyrene surfaces. Gel contraction was assessed via releasing the collagen gels from attachment following 24 h incubation in serum free, TGF-beta1-treated, or 1,25-(OH)(2)D(3)-treated media.

A highly sensitive technique to measure myosin regulatory light chain phosphorylation: the first quantification in renal arterioles.

Am J Physiol Renal Physiol

June 2008

Department of Pharmacology, Univ. of Calgary Faculty of Medicine, Smooth Muscle Research Group, 3330 Hospital Dr. N.W., Calgary, Alberta T2N 4N1, Canada.

Phosphorylation of the 20-kDa myosin regulatory light chains (LC(20)) plays a key role in the regulation of smooth muscle contraction. The level of LC(20) phosphorylation is governed by the relative activities of myosin light chain kinase and phosphatase pathways. The regulation of these two pathways differs in different smooth muscle types and in the actions of different vasoactive stimuli.

The extent to which the prostacyclin (IP) receptor regulates the release of two proinflammatory chemokines from human airway epithelial cells was investigated using the novel and competitive IP-receptor antagonist 4,5-dihydro-1H-imidazol-2-yl)-[4-(4-isopropoxy-benzyl)-phenyl]-amine (RO1138452). In BEAS-2B human airway epithelial cells, taprostene, a selective IP-receptor agonist, suppressed interferon-gamma-induced CXCL9 and CXCL10 release in a concentration-dependent manner. These effects were mimicked by 8-bromo-cAMP, and they were abolished in cells infected with an adenovirus vector encoding a highly selective inhibitor of cAMP-dependent protein kinase (PKA).
