Potent type-specific de novo antibodies complement broadly reactive imprinted antibodies in immune responses to SARS-CoV-2 variants
Abstract For rapidly mutating viruses such as influenza viruses and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), immune memory recalled by antigenically drifted variants primarily comprises antibodies that cross-react to the priming strain rather than de novo elicited responses, a phenomenon termed original antigenic sin or immune imprinting. The composition and functionality of de novo responses elicited by variant exposures remain unclear.
SARS-CoV-2 variant booster vaccination and infection alter the breadth of the memory B cell repertoire

Editor’s summary Abstract Supplementary Materials REFERENCES AND NOTES Information & Authors Metrics & Citations Check Access References Figures Tables Media Share Editor’s summary As SARS-CoV-2 continues to evolve in response to vaccine- and infection-induced immune pressure, vaccines will need to be updated to match currently circulating strains. Here, Malek et al. evaluated what impact a SARS-CoV-2 Omicron variant booster vaccine had on the overall memory B cell (MBC) response to SARS-CoV-2.

VRC01 with antiretroviral initiation in infants is well tolerated, and higher concentrations associate with greater HIV-1 DNA declines
|
Editor’s summary Although broadly neutralizing antibodies (bNAbs) have shown promise as both a prophylactic and therapeutic agent for HIV-1, most of the clinical studies in this area have recruited adult participants. To ask whether bNAbs might be effective at controlling HIV-1 in infants, Khaitan et al. conducted a clinical trial recruiting infants with HIV-1 who initiated antiretroviral therapy (ART) within the previous 14 days.

SARS-CoV-2 vaccination and infection elicit cross-neutralizing responses against clade 3 and 4 sarbecoviruses
Abstract Two sarbecoviruses, SARS-CoV-1 and SARS-CoV-2 that engage ACE2 through their receptor-binding domains, have caused major human outbreaks. The pandemic potential of sarbecoviruses has prompted the discovery and classification of bat and other zoonotic sarbecoviruses that are also able to use human ACE2 or ACE2 ortholog receptors for infection. However, the current human immunological landscape reactive to these SARS-CoV-2-related viruses is not well profiled.

Novel Approaches to Improve Scratch and Abrasion Resistance in UV Coatings
As UV coatings continue to be applied to a broader range of substrates, the demand for scratch and abrasion resistance continues to grow. This is especially true with thin-film applications over flexible, semi-porous or hard substrates with varying types of gloss or haptic properties. There are a variety of ways in which damage can occur due to various geometries and forces of the objects scraping over the coating surfaces.
