Happy to have the latest @amywchung.bsky.social lab preprint online! 🦠 Here we demonstrated that systemic inflammation in solid tumor malignancy patients was associated with impaired SARS-CoV-2 neutralizing antibody functions while non-neutralizing functions remained robust (yay Fc functions!) 🦠

Nice summary and discussion about our recent IgG4 publication that just came out on #scienceadvances from @amywchung.bsky.social lab (kudos to our PhD candidate Carissa Aurelia 👩‍🔬🎉)

Glad it has answered some technical questions and raised more for future work/discussion 🧐🔬🧪

Increased SARS-CoV-2 IgG4 has variable consequences dependent upon Fc function, Fc receptor polymorphism, and viral variant Elevated SARS-CoV-2–specific IgG4 titers decrease ADCC but can increase ADCP when spike-specific antibody titers are low.

Excited to share new work by PhD student Carissa Aurelia that examines the functional impact of IgG4 from repeated mRNA vaccination in Sci Adv. www.science.org/doi/10.1126/... 🙏🏼 @kev-in-science.bsky.social @ruthamypurcell.bsky.social @viralvaxlab.bsky.social @thedohertyinst.bsky.social
