About the LPDG

We are a free, local proteomics seminar series in the South East,
with a focus towards networking, discussion and supporting early career researchers.

The LPDG...

was founded to bring together the large community of proteomics scientists all working in and around London. We aim to provide a space for discussion, with a focus on methods and early career researchers (two fundamental building blocks of good research!), on all topics related to proteomics. The meetings comprise of research talks framed by a proteomics methods challenge, lunch, refreshments and pizza - they are free to attend thanks to sponsorship.

SARS-CoV-2: What Role Can Proteomics Play?

for 24th July 2020 14:00 BST
Last updated 10th July 2020

Dr Jeroen Demmers

Targeted Proteomics for the Detection of SARS-CoV-2 Proteins

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the causative agent of coronavirus disease 2019 (COVID-19). The rapid, sensitive and specific diagnosis of SARS-CoV-2 by fast and unambiguous testing is widely recognized to be critical in responding the current outbreak. Since the current testing capacity by conventional PCR based methods is insufficient because of shortages of supplies such as RNA extraction kits and PCR reagents, alternative and/or complementary testing assays should be developed. Here, we exploit the potential of targeted mass spectrometry based proteomic technologies to solve the current issue of insufficient SARS-CoV-2 diagnostic testing capacity. We have assessed the limit of detection by parallel reaction monitoring (PRM) on an Orbitrap Eclipse mass spectrometer for target tryptic peptides of several SARS-CoV-2 proteins from a sample of virus infected Vero cells. For Nucleocapsid protein the limit of detection was found to be in the mid-attomole range (0.9 × 10−12 g), which would theoretically correspond to approximately 10,000 SARS-CoV-2 particles, under the assumption that all viral proteins are assembled in macromolecular virus particles. Whether or not this sensitivity is sufficient to play a role in SARS-CoV-2 detection in patient material such as swabs or body fluids largely depends on the amount of viral proteins present in such samples and is subject of further research. If yes, mass spectrometry based methods could serve as a complementary protein based diagnostic tool and further steps should be focused on sample preparation protocols and on improvements in sample throughput.

Multi-level proteomics reveals host-perturbation strategies of SARS-CoV-2 and SARS-CoV

The sudden global emergence of SARS-CoV-2 urgently requires an in-depth understanding of molecular functions of viral proteins and their interactions with the host proteome. Several omics studies have extended our knowledge of COVID-19 pathophysiology, including some focused on proteomic aspects1–3. To understand how SARS-CoV-2 and related coronaviruses manipulate the host we here characterized interactome, proteome and signaling processes in a systems-wide manner. This identified connections between the corresponding cellular events, revealed functional effects of the individual viral proteins and put these findings into the context of host signaling pathways. We investigated the closely related SARS-CoV-2 and SARS-CoV viruses as well as the influence of SARS-CoV-2 on transcriptome, proteome, ubiquitinome and phosphoproteome of a lung-derived human cell line. Projecting these data onto the global network of cellular interactions revealed relationships between the perturbations taking place upon SARS-CoV-2 infection at different layers and identified unique and common molecular mechanisms of SARS coronaviruses. The results highlight the functionality of individual proteins as well as vulnerability hotspots of SARS-CoV-2, which we targeted with clinically approved drugs. We exemplify this by identification of kinase inhibitors as well as MMPase inhibitors with significant antiviral effects against SARS-CoV-2.

Dr Jeroen Demmers
Dr Jeroen Demmers
Dr Jeroen Demmers Erasmus University,
Netherlands

Dr Demmers is director of the proteoimcs facility at the Erasmus University Medical Center, having completed his PhD in Heck and Killian labs at Utrech University and a postdoc in the Chait lab at The Rockerfeller University, New York. His research interests in mass spectrometry and proteomics extend into quantitation, targetted proteomes, PTM analysis, transcription/gene regulation in health and disease and chromatin biology.

Prof Andreas Pichlmair
Prof Andreas Pichlmair
Prof Andreas Pichlmair School of Medicine,
Technical University of Munich

Professor Pichlmair (b. 1978) researches the interaction between viral pathogens and their host organisms. Professor Pichlmair primarily uses mass spectrometry and similar “large scale” techniques in order to conduct system analyses. The hypotheses drawn from such analyses serve to identify signaling cascades and mechanisms involved in the antiviral immune response. In 2008 he obtained a PhD from the London Research Institute, Cancer Research UK, where he was supervised by Professor Caetano Reis e Sousa. From 2008 to 2011, he worked as a post-doc at the Center for Molecular Medicine, Austria Academy of Sciences under Professor Giulio Superti-Furga. He set up his own laboratory at the Max Planck Institute of Biochemistry, Munich, as part of the Max Planck Free Floater Program (2011-2017). Professor Pichlmair took up a professorship at TUM in July 2017.
