New Paper: “A pleurocidin analogue with greater conformational flexibility, enhanced antimicrobial potency and in vivo therapeutic efficacy”

The 2016 Review on Antimicrobial Resistance (AMR) predicts that, unless action is taken, around 10 million deaths per year will be attributable to AMR by the year 2050. The pipeline of new antibiotics is limited, hence the potential of numerous alternatives to antibiotics – “noncompound approaches (i.e. products other than …

New Paper: “Supramolecular architecture of a multi-component biomimetic lipid barrier formulation”

Biomimetic liquid crystalline systems are widely used in skin care cosmetics and topical pharmaceutical preparations. Multi-component lipid/surfactant formulations that contain natural phospholipids combined with long chain fatty acids and alcohols are widely employed in so-called ‘biomimetic’ skin care preparations. Such products – which include, for example, the PhysiogelTM and BiophilicTM …

New Paper: “Morphology of bile salts micelles and mixed micelles with lipolysis products, from scattering techniques and atomistic simulations”

Bile salts (BS) are biosurfactants released into the small intestine, which play key and contrasting roles in lipid digestion: they adsorb at interfaces and promote the adsorption of digestive enzymes onto fat droplets, while they also remove lipolysis products from that interface, solubilising them into mixed micelles. Small architectural variations …

New Paper: “Effect of lipid heterogeneity on model human brain lipid membranes”

In this manuscript, we present important findings of how lipid heterogeneity in model lipid membranes affect various structural and dynamic properties of the lipids within the membranes .  We report the results of large-scale all-atom molecular dynamics simulations of commonly used simple model lipid membranes as well as two complex …

New paper: “ILC1 drive intestinal epithelial and matrix remodelling”

In our latest papers, we have participated in a multi-disciplinary collaboration investigating how type-1 innate lymphoid cells (ILC1) drive gut epithelial and matrix remodelling through TGFβ1 and MMP9, which has implications for patients with inflammatory bowel disease (IBD).  We used coarse-grain molecular dynamics simulations to gain an understanding of the …

New Paper: “Two coexisting membrane structures are defined by lateral and transbilayer interactions between sphingomyelin and cholesterol”

Sphingomyelin and cholesterol are prominent lipids in the plasma membrane of animal cells.  In this manuscript, we have combined X-ray scattering experiments, performed by our collarborator Prof. Peter Quinn (KCL, Institute of Pharmaceutical Science), and all-atom molecular dynamics to investigate the bilayer structures observed within an equimolar mixture of palmitoylsphingomyelin …

New Paper: “Time‐Resolved Fluorescence Anisotropy of a Molecular Rotor Resolves Microscopic Viscosity Parameters in Complex Environments”

Lipid droplets are cytoplasmic organelles that store neutral lipids (e.g. triacylglycerols & sterol esters) that serve as reservoirs of energy. The neutral lipid core of lipid droplets are bounded by a phospholipid monolayer, which differentiates them from most other organelles that have a bilayer membrane. There are various nano-environments of …

Irene Marzuoli successfully defended her PhD thesis

On 31 January, Irene Marzuoli, who was co-supervised by Prof. Franca Fraternali in the Randall Centre for Cell & Molecular Biology, was examined by Prof. Syma Khalid (University of Southampton) and Prof. Fernando Bresme (Imperial College London) during her PhD viva.  Irene’s viva was during the afternoon, and in the end the examiners …

Our paper on antimicrobial pseudocapsids is garnering a lot of attention

We are excited that our recent paper in which we reported the results of a multi-disciplinary investigation of the antimicrobial activity of protein pseudocapsids (ACS Nano (2020) 14, 1609-1622) has been garnering a lot of attention within the media and the scientific community since its publication.  This paper contained simulation …
