Identification of Pseudomonas aeruginosa exopolysaccharide Psl in biofilms using 3D OrbiSIMS (2023)
Journal Article

Secondary ion mass spectrometry (SIMS) offers advantages over both liquid extraction mass spectrometry and matrix assisted laser desorption mass spectrometry in that it provides the direct in situ analysis of molecules and has the potential to preser...

Carbohydrates from Pseudomonas aeruginosa biofilms interact with immune C-type lectins and interfere with their receptor function (2021)
Journal Article

Bacterial biofilms represent a challenge to the healthcare system because of their resilience against antimicrobials and immune attack. Biofilms consist of bacterial aggregates embedded in an extracellular polymeric substance (EPS) composed of polysa...

Development of dual anti-biofilm and anti-bacterial medical devices (2020)
Journal Article

The rising occurrence of antimicrobial resistance demands new strategies for delivering antibiotics to ensure their effective use. In this study, a multi-functional strategy to address medical device associated infections is explored whereby an anti-...

Patients with TNF Receptor Associated Periodic Syndrome (TRAPS) are hypersensitive to Toll‐like receptor 9 stimulation (2019)
Journal Article

Tumour necrosis factor receptor‐associated periodic syndrome (TRAPS) is an hereditary autoinflammatory disorder characterised by recurrent episodes of fever and inflammation. It is associated with autosomal dominant mutations in TNFRSF1A, which encod...

IFN-γ and IL-17A differentially influence the response of human macrophages and neutrophils to Pseudomonas aeruginosa infection (2018)
Journal Article

Macrophages are important orchestrators of inflammation during bacterial infection acting both as effector cells and as regulators of neutrophil recruitment and life span. Differently activated macrophage populations with distinct inflammatory and mi... Read More about IFN-γ and IL-17A differentially influence the response of human macrophages and neutrophils to Pseudomonas aeruginosa infection.

Integrin-mediated interactions control macrophage polarization in 3D hydrogels (2017)
Journal Article

Adverse immune reactions prevent clinical translation of numerous implantable devices and materials. Although inflammation is an essential part of tissue regeneration, chronic inflammation ultimately leads to implant failure. In particular, macrophag...

Controlling Incoming Macrophages to Implants: Responsiveness of Macrophages to Gelatin Micropatterns under M1/M2 Phenotype Defining Biochemical Stimulations (2017)
Journal Article

Adverse immune reactions to implanted devices can seriously hamper the efficacy of implants. Monocyte derived macrophages play a crucial role in both initiation and resolution of the inflammatory response toward foreign bodies. As the surface microt...

Unbiased analysis of the impact of micropatterned biomaterials on macrophage behaviour provides insights beyond pre-defined polarisation states (2017)
Journal Article

Macrophages are master regulators of immune responses towards implanted biomaterials. The activation state adopted by macrophages in response to biomaterials determines their own phenotype and function as well as those of other resident and infiltrat...

Electrohydrodynamic printing as a method to micropattern large titanium implant surfaces with photocrosslinkable structures (2017)
Journal Article

Metallic implants are widely used in orthopaedic and orthodontic applications. However, generally surface treatment of the metallic surfaces is necessary to render them more biologically active. Herein, we describe a direct write printing method to m...

Modulation of the immune response to Mycobacterium tuberculosis during malaria/M. tuberculosis co-infection (2016)
Journal Article

Tuberculosis (TB) causes significant morbidity and mortality on a global scale. The African region has 24% of the world's TB cases. TB overlaps with other infectious diseases such as malaria and HIV, which are also highly prevalent in the African reg...

The impact of surface chemistry modification on macrophage polarisation (2016)
Journal Article

Macrophages are innate immune cells that have a central role in combating infection and maintaining tissue homeostasis. They exhibit remarkable plasticity in response to environmental cues. At either end of a broad activation spectrum are pro-inflamm... Read More about The impact of surface chemistry modification on macrophage polarisation.

Immunomodulation with self-crosslinked polyelectrolyte multilayer-based coatings (2016)
Journal Article

This study aims to design an optimal polyelectrolyte multilayer film of poly-L-lysine (PLL) and hyaluronic acid(HA) as an anti-inflammatory cytokine release system in order to decrease the implant failure due to any immune reactions. The chemical mod... Read More about Immunomodulation with self-crosslinked polyelectrolyte multilayer-based coatings.

Granulocyte-macrophage colony stimulatory factor enhances the pro-inflammatory response of interferon-?-treated macrophages to pseudomonas aeruginosa infection (2015)
Journal Article

Pseudomonas aeruginosa is an opportunistic pathogen that can cause severe infections at compromised epithelial surfaces, such those found in burns, wounds, and in lungs damaged by mechanical ventilation or recurrent infections, particularly in cystic...

Impact of surface chemistry and topography on the function of antigen presenting cells (2015)
Journal Article

Antigen presenting cells (APCs) such as macrophages and dendritic cells (DCs) play a crucial role in orchestrating immune responses against foreign materials. The activation status of APCs can determine the outcome of an immune response following imp... Read More about Impact of surface chemistry and topography on the function of antigen presenting cells.
