Webinar Content

On Wednesday 29 April 2020, the second webinar in the COVID-19 series was organised. The State-of-the-Art Webinars on COVID-19 is a series of webinars presenting different talks on this specific coronavirus.

This second online seminar was given by Prof. Dr. Susan R. Weiss, Professor of Microbiology, Perelman School of Medicine, University of Pennsylvania. She gave an introductory presentation on Coronaviruses in general, covering their history, their replication and their innate immune antagonism.

The webinar was offered via Zoom and required registration in order to attend, however, the full recording can be found below.

The next edition of the State-of-the-Art Webinars on COVID-19 will be held on Friday 8 May 2020 at 11:00am (CEST). The guest speaker will be Prof. Dr. Mark Nieuwenhuijsen, Research Professor in Environmental Epidemiology at ISGlobal, Barcelona Institute for Global Health – Campus MAR. He will be giving a presentation entitled: “Could the COVID-19 Crisis be the Opportunity to Make Cities Carbon Neutral, Liveable and Healthy”. You can register here.

Unanswered Questions during Q&A Session

  1. Endo U will not cleave viral RNAs?

Yes, it will cleave viral RNA. We have a paper coming out on that. We think it does so to limit dsRNA accumulation and subsequent IFN response.

  1. What are the biggest challenges in developing vaccines?

Not something I can answer, but I think that it takes time, it needs to be scaled up and tested.

  1. Do you know if there is an evidence of a link between Guillain-Barré Syndrome (GBS) and SARS-CoV infection?

None that I know of.

  1. Do you have any thoughts about genetic susceptibility to infection and to disease severity?

I am sure people are looking at that now, but no current data.

  1. Can SARS-CoV2 kill any human epithelial cells in vitro?

I think it can kill epithelial cells lines, we are looking at primary cells.

  1. What types of cells can robustly support the replication of these viruses, particularly SARS-CoV-2?

Cell lines (Vero, Caco) for two; each CoV is different in which cells it can replicate in.

  1. What is known about the route of transmission of the virus to the CNS?

I think probably nothing is known.

  1. I am wondering about the IgA potential in the 1st line immune response, since they are produced in both mucosals of the respiratory and GI tracts?

I do not know about this.

  1. I was wondering if we know how the translation of the slippery sequence through the frame shift is regulated to maintain the correct ratio of pp1a/pp1b? Are there any known host factors known to be involved?

Not known but I think interesting; if you alter the ratio of pp1a/pp1ab the virus is very attenuated.

  1. If the virus has the possibility of enter by fusion, is it possible that it would be inhibited by chloroquine or other endocytosis acidification inhibitor drugs?

Yes if it enters through the endosomal pathway.
