Single-Step Detection of the Influenza Virus Hemagglutinin Using Bacterially-Produced Quenchbodies.

ABSTRACT: We have successfully generated a Quenchbody that enables the detection of the influenza virus hemagglutinin (HA), in a simple and convenient manner. By two-site labeling of the bacterially-produced anti-HA Fab with ATTO520, its fluorescence intensity was increased to 4.4-fold, in the presence of a nanomolar concentration of H1N1 HA. Our results indicate the potential use of this Quenchbody, as a sensor for the simple in situ detection of influenza A virus.

Single cell RNA-seq of hemagglutinin specific B cells after influenza virus infection: VDJ data

Project description:Understanding dynamics of antigen specific B cell responses and link between BCR and B cell differentiation is crucial for our ability to direct immune responses and to generate memory and plasma cells responses to protective targets. Here we have infected mice with IAV-PR8 and sacrificed them at different days after infection (7-14-28). 2 naive mice were used as controls (spleen and lungs). From individual spleen, lungs and mediastinal lymph nodes we have sorted Hemagglutinin (HA)-specific IgD- B cells and single cell sequenced RNA and BCR. We identify several known and novel B cell subpopulations forming after infection and find organ-specific difference that persist over the course of the response. We found important transcriptional differences between memory cells in lungs and immune organs and describe organ-restricted clonal expansion. Strikingly, by combining BCR mutational analysis, monoclonal antibody expression and affinity measurements we found no differences between germinal center (GC)-derived memory and plasma cells, at odds with an affinity-based selection model. These finding provide the most comprehensive picture to date of organ specific antiviral B cell responses, differentiation, clonal-proliferation and dynamics.
