In work led by @bdadonaite @khdcrawford @CaelanRadford, we develop pseudovirus system to deep mutational scan full #SARSCoV2 spike: https://t.co/O6MGHXVWdS TLDR: can now safely measure how all mutations to viral entry proteins affect antibody neutralization. 🧵 below (1/n)

A major challenge in understanding SARS-CoV-2 evolution is interpreting the antigenic and functional effects of emerging mutations in the viral spike protein. Here we describe a new deep mutational...

We first report the effects of all mutations on ACE2 binding affinity and protein folding stability. Interactive versions of these maps (together maps from prior SARS2 variants), are available here: https://t.co/u0GpKYop3g Like prior maps, we see wide tolerance to mutation.

Our newest study is up, where we report deep mutational scanning data in the Omicron BA.1 and BA.2 receptor-binding domains
biorxiv.org
SARS-CoV-2 continues to acquire mutations in the spike receptor-binding domain (RBD) that impact ACE2 receptor binding, folding stability, and antibody recognition. Deep mutational scanning prospec...

New paper from @jbloom_lab about the importance of ACE2 expression on target cells on SARS-CoV-2 neutralization - thanks #HAARVI participants for contributing to these studies.
In new study, we examine how target cell ACE2 expression affects #SARSCoV2 neutralization https://t.co/47RTQ5aeSS We find high-ACE2 cells emphasize role of RBD antibodies in serum & lower ACE2 cells reveal more neutralization by antibodies to other regions of spike. 🧵 below:

In new study led by @dbacsik, we show single influenza-infected cells produce wildly different numbers of viral progeny: https://t.co/mZSRW3k2iw Surprisingly, cells that transcribe the most viral mRNA are NOT ones that produce the most progeny virions. Explanatory 🧵 below

The ultimate success of a viral infection at the cellular level is determined by the number of progeny virions produced. However, most single-cell studies of infection quantify the expression of...

Was a pleasure to contribute to this very cool study looking at how heterologous boosting elicits new versus boosted original antigenic sin antibody responses in mice from @victora_lab !

Our latest review is now out in @BiochemistryACS! In this Perspective, we discuss the importance of InDels in protein evolution, whether in nature or the test tube, and strongly advocate their potential for protein engineering. @tokuriki_lab
pubs.acs.org
Over the years, protein engineers have studied nature and borrowed its tricks to accelerate protein evolution in the test tube. While there have been considerable advances, our ability to generate...

We have a position in the Bloom lab for a research tech interested in using deep mutational scanning to study evolution of viruses including SARS-CoV-2 & influenza: https://t.co/o6yLQZfkQY (And while this ad is for a tech, we are always open to inquiries from postdoc candidates)

If you’re into viral, antibody, or protein evolution, check out the 🌟 Starr lab 🌟! Can confirm that @tylernstarr is one of the most brilliant, fun, and supportive scientists out there! Already envious of the new folks who get to work with you!
🥳 Excited to share that the Starr Lab is coming to the University of Utah @UofUBiochem! Check out the lab website to see where we’re headed in our studies of protein evolution in viruses and immunity

Excited to share our work on epistasis shaping the evolution of SARS-CoV-2 BA.1 — had a blast working on this with @AliefMoulana @ThomasDupic Jeffrey Chang, @MichaelMDesai & @jbloom_lab:
biorxiv.org
The Omicron BA.1 variant emerged in late 2021 and quickly spread across the world. Compared to the ancestral Wuhan Hu-1 strain and other pre-Omicron SARS-CoV-2 variants, BA.1 has many mutations, a...

What a special moment: the #COVID19 vaccine we designed with @coronalexington @KingLabIPD has met its primary endpoints in the phase 3 clinical trial run by SK bioscience!!! @HHMINEWS

A Phase 3 clinical trial found that the second-generation vaccine generates high levels of neutralizing antibodies.

Wanted to add to @DrNeeltje's nice summary about the recent pre-print on @Acoh92 @bjorkmanlab's mosaic RBD nanoparticle vaccine, which at least in animals induces "broader" antibody immunity to #SARSCoV2 variants and other SARS-related CoVs: https://t.co/YHMnJjPOe6 (1/n)

To combat future SARS-CoV-2 variants and spillovers of SARS-like betacoronaviruses (sarbecoviruses) threatening global health, we designed mosaic nanoparticles presenting randomly-arranged sarbecov...

(10/n) In the future, it would be good to understand the specificity of the antibody response to Omicron and which mutations might erode that immunity.

(9/n) And thanks to our collaborators @sigallab @HelenChuMD Cate Speake and their teams, including @KhadijaKhan24 @SkiClimbSciNick @jenni_logue. (And of course @jbloom_lab mates @tylernstarr and @eguia_rachel) It was so fun to work with you all!
