Cells, Systems and Mechanics
Our community of researchers employ interdisciplinary approaches and innovative tools to probe fundamental biological systems. These systems span scales, from intracellular organisation and signalling through to the structure and behaviour of tissues.
Research Highlights
-
A newly discovered protease enzyme from a little-known category of bacteria called Candidate Phyla Radiation has been found to have remarkable similarity to a human protease. A team led by Professor Ehmke Pohl (Durham Biosciences) have used metagenomics to investigate the thermostable protease, which given its structure and thermal behaviour, has interesting potential for use in biotechnology. Find out more here.
-
Dr Karrera Djoko (Durham Biosciences) and a team of multidisciplinary colleagues have gained new insight to the mode of action of the antimicrobial peptide Histadin-5. The zinc-binding Hst5, part of the histadine-rich family of peptides found in human saliva has been shown not to out-compete a model Streptococcus for Zn(II) as expected, but to have antimicrobial properties through a different mechanism. Find out more here.
- Interdisciplinary approaches are increasing our understanding of stress granules, these biomolecular condensates are formed in response to cellular stresses and have important intracellular roles. A team, including Professors Halim Kusumaatmaja (Durham Physics) and Sushma Grellscheid (University of Bergen) are using a new approach to study the rheological behaviour of these condensates.

Magnitude Biosciences
Magnitude Biosciences is a Durham University spin-out company founded in 2018 by an interdisciplinary team with world leading expertise in C.elegans and automated imaging. Dr David Weinkove (Durham Biosciences, Chief Scientific Officer Magnitude Biosciences) and Dr Chris Saunter (Chief Technical Officer Magnitude Biosciences) developed their unique technology, the Healthspan Machine, into a commercial platform which now benefits academic and industrial laboratories around the world. We supported the collaboration in its very early stages in 2014 through a small BSI Seedcorn funding award, and also in 2017 through our support of a focussed research workshop.
