Immunomodulation of human T cells by microbubble-mediated focused ultrasound

Author(s): Baez A; Singh D; He S; Hajiaghayi M; Gholizadeh F; Darlington PJ; Helfield B;

While met with initial and ground-breaking success targeting blood borne cancers, cellular immunotherapy remains significantly hindered in the context of solid tumors by the tumor microenvironment. Focused ultrasound, in conjunction with microbubbles, has found tremendous potential as a targeted and local drug/gene delivery technique for cancer therapy. T ...

The β2-adrenergic biased agonist nebivolol inhibits the development of Th17 and the response of memory Th17 cells in an NF-κB-dependent manner

Author(s): Hajiaghayi M; Gholizadeh F; Han E; Little SR; Rahbari N; Ardila I; Lopez Naranjo C; Tehranimeh K; Shih SCC; Darlington PJ;

Introduction: Adrenergic receptors regulate metabolic, cardiovascular, and immunological functions in response to the sympathetic nervous system. The effect of ß2-adrenergic receptor (AR) as a high expression receptor on different subpopulations of T cells is complex and varies depending on the t ...

The β2-adrenergic receptor agonist terbutaline upregulates T helper-17 cells in a protein kinase A-dependent manner

Author(s): Carvajal Gonczi CM; Hajiaghayi M; Gholizadeh F; Xavier Soares MA; Touma F; Lopez Naranjo C; Rios AJ; Pozzebon C; Daigneault T; Burchell-Reyes K; Darlington PJ;

Background: T helper 17 (Th17) cells produce IL-17A cytokine and can exacerbate autoimmune diseases and asthma. The ß2 adrenergic receptor is a g protein-coupled receptor that induces cAMP second messenger pathways. We tested the hypothesis that terbutaline, a ß2-adrenergic receptor-specific agon ...

Genetic Screening of Candida albicans Inactivation Mutants Identifies New Genes Involved in Macrophage-Fungal Cell Interactions

Author(s): Godoy P; Darlington PJ; Whiteway M;

Candida albicans, an important fungal pathogen of humans, displays different morphologies, such as yeast, pseudo-hyphae and hyphae, which are recognized unequally by phagocytic cells of the innate immune response. Once C. albicans cells invade host tissues, immune cells such as macrophages are attracted to the site of infection and activated to recognize, ...

Elevated Heart Rate and Pain During a Cold Pressor Test Correlates to Pain Catastrophizing

Author(s): Kakon G; Mohamadi AK; Levtova N; Maurice-Ventouris MEI; Benoit EA; Chouchou F; Darlington PJ; Dover G;

To understand the variable response to pain, researchers have examined the change in cardiovascular measures to a uniform painful stimulation. Pain catastrophizing is the tendency to magnify or exaggerate pain sensations, and it affects the outcome of rehabilitation in a clinical setting. Its eff ...

Association Between Pain Catastrophizing and Pain and Cardiovascular Changes During a Cold-Pressor Test in Athletes

Author(s): Lentini M; Scalia J; Lebel FB; Touma F; Jhajj A; Darlington PJ; Dover G;

Context: Athletes are often exposed to pain due to injury and competition. Using preliminary evidence, researchers have shown that cardiovascular measures could be an objective measure of pain, but the cardiovascular response can be influenced by psychological factors, such as catastrophizing. Objective: To use a painful cold-pressor test (CPT) to measur ...

Pain catastrophizing in athletes correlates with pain and cardiovascular changes during a painful cold pressor test

Author(s): Matylda L; Joseph S; Frédérike BL; Fadi T; Aneet J; Darlington PJ; Dover G;

Context: Athletes are often exposed to pain due to injury and competition. There is preliminary evidence that cardiovascular measures could be an objective measure of pain, but the cardiovascular response can be influenced by psychological factors such as catastrophizing. Objectives: The purpose of our study was to use a painful cold pressor test to meas ...
