We recently interviewed Dr Shahed Yousaf, Warwick Medical School alumnus who graduated in 2006. He lives in Birmingham and has been a GP for ten years working with the homeless and with prisoners. He is also an accomplished writer, starting off his writing career with fiction, he has now published ‘Stitched Up’ which follows his career in medicine working with patients on the edge of society.

All cells must accurately separate their chromosomes during mitosis to avoid errors that are associated with cancer development, reproductive failure and even ageing. This feat is accomplished by the mitotic spindle – this microtubule-based machine has a bipolar geometry and contains hundreds of protein components. A subset of microtubules form bundles that make contact with kinetochores on the chromosome (these are called K-fibres). The growth and shrinkage of these microtubules, through addition and loss of tubulin, is coupled to the hydrolysis of GTP: this powers chromosome movement. Previous work identified a protein called HURP (hepatoma up-regulated protein) that forms distinctive stripes on each half spindle (see schematic). Here, through collaboration with University of Geneva, we identified a new region within the mitotic spindle, termed “HURP-gap”. This HURP free region of the K-fibre is located between the stripe and the kinetochore.

Discovery: How do organs reach a specific size during development? The Hippo/YAP pathway has been identified as a critical regulator of organ size control. It also plays an important role in homeostasis and cancer progression, in part due to its mechanosensitive response. Here, the Saunders lab have developed an optogenetic version of YAP (optoYAP) that enables its localisation to the nucleus to be tightly controlled in both space and time. This enables targeted perturbation of the pathway, with potential applications to wound healing and regeneration.

The GibsonGroup are developing macromolecular (polymer) cryoprotectants to enable next-generation cell based therapies, and to simplify cell-based assays. A key feature identified in the teams most potent materials is a mixture of cationic/anionic charges on the side chain, but the exact mechanism of action is under investigation. In this latest work the team explored sulphoxide (‘DMSO like’) side chains, which are actually highly polarised with S+-O- character. The team also explore N-oxide polymers which have similar charged character. Using a range of phyical and biochemical assays the team investigated if these motifs could aid in cryopreservation.

The Data Science and Artificial Intelligence showcase will be held at Warwick this year and is open to anyone in the research teams and wider audiences active in Data Science and AI.
The two keynote speakers are directly aligned to Women in STEM, with Anne-Maire Imafidon almost confirmed as the closing plenary speaker.

There will also be a poster exhibition, and full details on how to enter can be found with this link Poster Competition - submissions just need to be a high-res PDF, all printing costs are covered and there are a few prizes up for grabs.

We have now published back to back two papers on the so called anthrax “cross over strain Bacillus cereus G9241. The first paper (From cereus to anthrax and back again: The role of the PlcR regulator in the “cross-over” strain Bacillus cereus G9241) has already been highlighted. This current paper is titled, “The influence of extrachromosomal elements in the anthrax “cross-over” strain Bacillus cereus G9241.”

The work investigates the contribution of anthrax-like plasmids and a lysogenic phagemid to the pathogenic potential of the normally relatively harmless Bacillus cereus. We investigated the role of temperature and carriage of the pBCXO1 plasmid (which is homologous to the pXO1 anthrax toxin plasmid) in regulation of chromosomal genes, heavily affecting metabolism. In addition we have shown that sporulation of G9241 is very rapid at 37’C, which is characteristic of B. anthracis but unlike the ancestral B. cereus strains. Finally we isolated phagemid virions which are produced at 37’C and visualised them with electron microscopy.

In our recent paper “From cereus to anthrax and back again: The role of the PlcR regulator in the “cross-over” strain Bacillus cereus G9241” we have investigated how a normally low risk Bacillus cereus strain has evolved to mimic Bacillus anthracis, the causative agent of the highly feared lethal anthrax infection. The B. cereus G9241 strain is one of several relatively recent isolates that are termed “anthrax cross over strains” that intriguingly seem to preferentially infect metal workers in the USA (welders / millers). These strains are of particular concern as, unlike B. anthracis proper, they can switch between a form that can survive and replicate in the environment using invertebrate hosts and the more lethal mammalian infective anthrax like form. B. anthracis must pass from mammalian host to mammalian host as a spore form thus somewhat limiting its spread. This is due to a loss of function mutation in a key regulator protein named PlcR, which in all other B. cereus sensu lato group strains allows for survival outside of a mammalian host. Our work has identified the specific mechanism by which G9241 can switch on and off the PlcR regulation endowing it with a “Dr. Jekyll or Mr. Hyde” like life cycle. This work was a culmination of a Marie Curie fellow, 3 PhD students and one postdoc and was supported by MoD Porton Down DSTL funding and advice, for which we are very grateful.

One of the key questions relating to the COVID-19 pandemic is how prior immunity to related endemic coronaviruses affects the SARS-CoV-2 immune response. In this study, we provide evidence of immunological imprinting in individuals with fatal outcomes from COVID-19, suggesting an antibody profile consistent with an original antigenic sin type-response.

Cansu Küey’s PhD work was published this week in eLife. Together with Méghane, Gabrielle and Miguel, she showed that clathrin-coated pits can be made to form on intracellular membranes. This phenomenon allowed us to redefine two key concepts in clathrin-coated vesicle formation. First, a scission molecule is not needed to pinch off vesicles inside the cell. Second, that most of the other proteins found in regular clathrin coats are not essential for vesicle formation.

The GibsonGroup, in collaboration with the Sosso Group (chemistry) are investigating how small molecules can inhibit ice recrystallisation - a property more commonly associated with macromolecules, such as ice binding proteins or some polymers. The challenge of the macromolecules is that sequential modification is challenging, and hence structure-property relationships are often missing. Here the team show that phenyl alanine can inhibit ice recrystallisation and that modulation of the hydrophobic face impacts the magnitude of the activity. This work shows that ’small molecule’ approaches can be taken to probe the complex ice/water interface, with the long term goal of finding new molecules to control ice growth.

This work answers the mystery surrounding when in evolution did a key class of membrane remodelling factors arise. The collaborative team comprising Balasubramanian (Warwick), Baum (Cambridge), Lowe (Cambridge), Robinson (Lancaster), and Ettema (Wageningen, Netherlands) worked on proteins encoded by Heimdall archaea, thought to be most related to eukaryotes. They found that, contrary to existing dogma, a complex eukaryote-like ESCRT family of membrane remodelling factors were present in archaea and are therefore not eukaryotic inventions. Warwick post-doctoral fellow and first author Hatano “reconstituted” key steps of the process using purified components helping arrive at the conclusions.

This 3.5 year PhD studentship provides a unique opportunity for a promising social or health science researcher to undertake research aimed at influencing the future of palliative care services. The student will investigate the relationship between wider ideas of society and healthcare as complex and how palliative care understands itself as addressing people’s ‘complex needs’.
