Airway smooth muscle (ASM) cells contribute to asthma pathology through their synthetic and mechanical (contractile) functions. Dr. Jude is interested in the molecular and cellular signaling mechanisms of ASM cells in airway disorders such as asthma. His current research focus is on the mechanisms of airway hypersensitivity exacerbation by environmental pollutants like ozone. Ozone and other environmental pollutants are associated exacerbation of clinical signs in asthmatic patients.
- Obesity alters airway smooth muscle phenotype
Obesity is associated with both allergic and non-allergic asthma. Our recent findings show that airway smooth muscle cells isolated from obese human donors have are hyper-reactive to contractile agonists. We have done a phospho-proteomics/proteomics screening to understand the proteomic signature of obese-donor derived ASM cells. Newer protein targets are being pursued to determine how obesity is linked to enhanced ASM cells shortening.
- Sensitizers act on airway smooth muscle and epithelial cells to modulate alarmin secretions and functions
Allergic and non-allergic asthma are exacerbated by environmental toxicants. Many of these toxicants are either occupational or ambient by origin. Our studies showed that exposure to ambient toxicant (formaldehyde in tobacco smoke) or occupational toxicant (DNCB) alter ASM cell function. Alarmins are a group of mediators secreted generally by airway structural cells in response to toxicant/pathogen exposure. Current experiments focus on how alarmins induced by specific toxicants (i.e: DNCB) regulate excitation-contraction coupling in ASM cells. We also focus on how these alarmins render the ASM cells insensitive to bronchodilators, a critical part of asthma therapy.
- Free fatty acid receptors regulate excitation-contraction coupling in airway smooth muscle cells
Free fatty acid levels are elevated in obese subjects. Receptors for some of these free fatty acids are expressed and functional in ASM cells. We are testing a hypothesis that free fatty acid receptors (FFAR) modulate excitation-contraction coupling in ASM cells.
- Cyclic AMP (cAMP) pump expression and function in airway smooth muscle cells
Cyclic AMP (cAMP) is an intracellular second messenger. It is elevated upon activation of beta2 adrenergic receptor (b2AR) on ASM cells. Bronchodilators, such as albuterol, act on b2AR to relax ASM. Recent reports showed that a cAMP pump, called ABCC1/4 (MRP1/4) is expressed in ASM cells. Pumping of cAMP by these proteins may reduce intra-cellular cAMP, therefore attenuate b2AR-induced ASM relaxation. Current experiments focus on expression levels of these proteins in ASM cells in non-asthma and asthma human donors.
- ANO1/TMEM16A: A chloride channel with potential role in cellular Ca2+ dynamics in airway smooth muscle cells
Membrane depolarization is one way of regulating voltage-sensitive Ca2+ channels in excitable cells, such as smooth muscle cells. Anoctamin 1 (ANO1) is a Ca2+-activated-Chloride channel expressed in ASM cells. Studies showed that inhibiting ANO1 with drugs, such as benzbromarone, attenuates contraction in human small airways. The current studies focus on regulation of ANO1 expression by various cytokines and the functional effects in ASM cells as the result of modified expression.
