Biography

Alain Pluen – a physical chemist by training – is a Senior Lecturer within the Division of Pharmacy and Optometrics. Alain joined the then School of Pharmacy in 2000 and has been pursuing his research effort on studying protein-protein interactions espectially aggregation in solution to understand issues related to biologics (e.g. mAbs) formulation and cells.  This is carried out using bioimaging techniques (confocal microscopy, Raster Image Correlation Spectroscopy or Fluorescence Correlation Spectroscopy) as well as light scattering (DLS, SLS).

A second area of research focuses on nanoparticles especially their formulation. In particular RNA lipid nanoparticles in order to extent the shelf life of these and reduce the reliance on the cold chain, and, hyrophobic ion pairs to improve the delivery of antimicrobials.

 Previously Alain did his post-graduate studies at the Institut Charles Sadron – Centre de Recherche sur les Macromolecules, (CNRS UPR 22, Strasbourg, France) where he studied the mechanisms of transport of macromolecules (single stranded DNA) in gels to improve sequencing (EU Biomed 1). Then in 1997, he joined the team of Prof. R.K. Jain at the Massachusetts General Hospital - Harvard Medical School as a post-doctoral research fellow. In this biomedical engineering laboratory and in collaboration with Dr. David Berk, he started to study the relation between the tumour microenvironment and the transport hindrance of novel medicines i.e. antibodies, protein, peptides or liposomes. In September 2000, he joined the then School of Pharmacy and Pharamceutical Sciences.

Research interests

Alain Pluen’s research team focuses on:


1. Understanding weak protein protein interactions especially for biopharmaceuticals using fluorescence techniques, light scattering.

In collaboration with Drs Curtis, Warwicker, Golovanov Profs Derrick and Dickson (MIB and FBMH). This work is supported by BBSRC and MedImmune. Aggregation propensity of mABs in simple solutions as well as real formulations has been deternined and compared to standard equipment (Hamrang et al. 2015 JPharm Sci and Shah et al. 2017 Int J Pharm). The effect of charge mutations on teh stability and aggregation of small chain Fv fragments studied (Austerberry et al., Eur J Pharm and Biopharm).

2. Improve the formulation of nanoparticles in particular RNA loaded lipid nanoparticles (effect of sterol variants on the stability of particles over time and different storage conditions) or the formation of hydrophobic ion pairs nanoparticles to deliver antimicrobial peptides.

3. Develop the use of Image Correlation Spectroscopies for quantifying :

  • peptides uptake in cells (Staley et al., Drug Discovery Today 2010) and to
  • protein and biologics aggregation phenomena in collaboration with the Centre of Excellence in Biopharmaceuticals (COEBP).
  • We have demonstrated the ability of Raster Image Correlation Spectroscopy at characterising the diffusional behaviour of proteins in solution under normal and stress conditions (Hamrang et al.,J Pharm Sci, 2010): using diffusion coefficients and local concentrations, variations of the particles distribution illustrate the effect of stress on protein solutions. A collaboration with Dr R Curtis (MIB) focuses on te mechanisms of protein aggregation using ManICS and Spatial Intensity Distribution. These concepts have also been applied to transport in biofilms (Rattray et al. Methods in Molecular Biology 2019, Buzza et al., Microbiology spectrum, 2023)

4. Exfoliation and stabilisation of pristine graphene suspensions using short peptides (Alkathiri et al., J Phys Chem C 2019)

5. Understanding the delivery of drugs or biologics 

Additionally, in collaboration with Dr Rauch (U. of Nottingham) the influence of phospholipids e.g. phosphatidylserine on drugs uptake in tumour cells is investigated (Rauch and Pluen, Eur J Biophysics 2007) as well as multidrug resistance (Rauch et al., Cellular Biochemistry and Biophysics 2010).
