A dynamical model of TGF-β activation in asthmatic airways (2023)
Journal Article

Excessive activation of the regulatory cytokine transforming growth factor β (TGF-β) via contraction of airway smooth muscle (ASM) is associated with the development of asthma. In this study, we develop an ordinary differential equation model that de... Read More about A dynamical model of TGF-β activation in asthmatic airways.

Differential remodelling in small and large murine airways revealed by novel whole lung airway analysis (2023)
Journal Article

Airway remodelling occurs in chronic asthma leading to increased airway smooth muscle (ASM) mass and extra-cellular matrix (ECM) deposition. Whilst extensively studied in murine airways, studies report only selected larger airways at one time point m...

The role of mathematical models in designing mechanopharmacological therapies for asthma (2022)
Journal Article

Healthy lung function depends on a complex system of interactions which regulate the mechanical and biochemical environment of individual cells to the whole organ. Perturbations from these regulated processes give rise to significant lung dysfunction... Read More about The role of mathematical models in designing mechanopharmacological therapies for asthma.

Reduced biomechanical models for precision-cut lung-slice stretching experiments (2021)
Journal Article

Precision-cut lung-slices (PCLS), in which viable airways embedded within lung parenchyma are stretched or induced to contract, are a widely used ex vivo assay to investigate bronchoconstriction and, more recently, mechanical activation of proremodel...

Switching behaviour in vascular smooth muscle cell–matrix adhesion during oscillatory loading (2020)
Journal Article

Integrins regulate mechanotransduction between smooth muscle cells (SMCs) and the extracellular matrix (ECM). SMCs resident in the walls of airways or blood vessels are continuously exposed to dynamic mechanical forces due to breathing or pulsatile b...

An Integrated Pipeline for Combining in vitro Data and Mathematical Models Using a Bayesian Parameter Inference Approach to Characterize Spatio-temporal Chemokine Gradient Formation (2019)
Journal Article

All protective and pathogenic immune and inflammatory responses rely heavily on leukocyte migration and localization. Chemokines are secreted chemoattractants that orchestrate the positioning and migration of leukocytes through concentration gradient...

A multiphase multiscale model for nutrient limited tissue growth, Part II: A simplified description (2019)
Journal Article

In this paper, we revisit and extend our recent work (Holden et al. (2018) A multiphase multiscale model for nutrient limited tissue growth, The ANZIAM Journal, 59(4), 499-532), that considers the derivation of an effective macroscale description sui...

Cellular uptake and efflux of palbociclib in vitro in single cell and spheroid models (2019)
Journal Article

Adequate drug distribution through tumors is essential for treatment to be effective. Palbociclib is a cyclin-dependent kinase 4/6 inhibitor approved for use in patients with hormone receptor positive, human epidermal growth factor receptor 2 negativ...

Small airway hyperresponsiveness in COPD: relationship between structure and function in lung slices (2019)
Journal Article

The direct relationship between pulmonary structural changes and airway hyperresponsiveness (AHR) in chronic obstructive pulmonary disease (COPD) is unclear. We investigated AHR in relation to airway and parenchymal structural changes in a guinea pig...

A theoretical model of inflammation- and mechanotransduction-driven asthmatic airway remodelling (2018)
Journal Article

© 2018, The Author(s). Inflammation, airway hyper-responsiveness and airway remodelling are well-established hallmarks of asthma, but their inter-relationships remain elusive. In order to obtain a better understanding of their inter-dependence, we de... Read More about A theoretical model of inflammation- and mechanotransduction-driven asthmatic airway remodelling.

Effect of loading history on airway smooth muscle cell-matrix adhesions (2018)
Journal Article

Integrin-mediated adhesions between airway smooth muscle (ASM) cells and the extracellular matrix (ECM) regulate how contractile forces generated within the cell are transmitted to its external environment. Environmental cues are known to influence t... Read More about Effect of loading history on airway smooth muscle cell-matrix adhesions.

A multiphase multiscale model for nutrient limited tissue growth (2018)
Journal Article

In this work, an effective macroscale description is derived for the growth of tissue on a porous scaffold. A multiphase model is employed to describe the tissue dynamics; linearisation to facilitate a multiple-scale homogenisation provides an effect...

In vitro, in silico and in vivo study challenges the impact of bronchial thermoplasty on acute airway smooth muscle mass loss (2018)
Journal Article

Bronchial thermoplasty is a treatment for asthma. Whether during thermoplasty the airway wall fraction exposed to temperatures necessary to affect cells is sufficient to explain its histopathological impact is unclear. Airway smooth muscle and bronc... Read More about In vitro, in silico and in vivo study challenges the impact of bronchial thermoplasty on acute airway smooth muscle mass loss.

A novel computational model predicts key regulators of chemokine gradient formation in lymph nodes and site-specific roles for CCL19 and ACKR4 (2017)
Journal Article

The chemokine receptor CCR7 drives leukocyte migration into and within lymph nodes (LNs). It is activated by chemokines CCL19 and CCL21, which are scavenged by the atypical chemokine receptor ACKR4. CCR7-dependent navigation is determined by the dist...

Mathematical modelling of cytokines, MMPs and fibronectin fragments in osteoarthritic cartilage (2017)
Journal Article

Osteoarthritis (OA) is a degenerative disease which causes pain and stiffness in joints. OA progresses through excessive degradation of joint cartilage, eventually leading to significant joint degeneration and loss of function. Cytokines, a group of...

Airway and Parenchymal Strains during Bronchoconstriction in the Precision Cut Lung Slice (2016)
Journal Article

The precision-cut lung slice (PCLS) is a powerful tool for studying airway reactivity, but biomechanical measurements to date have largely focused on changes in airway caliber.
