Geiger, Xuesong Chen 27 October 2021 SARS-CoV-2 is the viral cause of the COVID-19 pandemic. Increasingly, significant neurological disorders have been associated with COVID-19. However, the pathogenesis of these neurological disorders remains unclear especially because only low or undetectable levels of SARS-CoV-2 have been reported in human brain specimens. Because SARS-CoV-2 S1 protein can... read more https://doi.org/10.3389/fncel.2021.777738

P2020-001 Persistence of functional memory B cells recognizing SARS-CoV-2 variants despite loss of specific IgG Stephan Winklmeier, Katharina Eisenhut, Damla Taskin, Heike Rübsamen, Ramona Gerhards, Celine Schneider, et al. 20 December 2021 Although some COVID-19 patients maintain SARS-CoV-2-specific serum immunoglobulin G (IgG) for more than 6 months postinfection, others eventually lose IgG levels. We assessed the persistence of SARS-CoV-2-specific B cells in 17 patients, 5 of whom had lost specific IgGs after 5–8 months. Differentiation of blood-derived B cells ... read more https://doi.org/10.1016/j.isci.2021.103659

The viral glycoprotein Spike mediates fusion to the host cell membrane, but its role as a virulence factor is largely unknown. Recently, the antiviral activity of lactoferrin against SARS-CoV-2 was demonstrated in vitro and ... read more https://doi.org/10.3390/pharmaceutics14102111
P2020-030 Increased circulating microparticles contribute to severe infection and adverse outcomes of COVID-19 in patients with diabetes Haoyu Sun, Yong Du, Rinki Kumar, Nicholas Buchkovich, and Pingnian He 21 November 2022 Patients with diabetes infected with COVID-19 have greater mortality than those without comorbidities, but the underlying mechanisms remain unknown. This study aims to identify the mechanistic interactions between diabetes and severe COVID-19. Microparticles (MPs), the cell membrane-derived vesicles released on cell activation, are largely increased in patients with ... read more https://doi.org/10.1152/ajpheart.00409.2022

We analyzed immune response dynamics in 28 families up to 12 months after mild or asymptomatic infection. Unlike adults, the initial response is plasmablast-driven in children. Four months after infection, children show an enhanced specific antibody response and lower but detectable spike 1 protein (S1)-specific B and T cell ... read more https://doi.org/10.1038/s41467-022-35055-1
P2020-001 Impedimetric Nanobiosensor for the Detection of SARS-CoV-2 Antigens and Antibodies Diana Isabel Sandoval Bojórquez, Željko Janićijević, Brenda Palestina Romero, Eduardo Sergio Oliveros Mata, Markus Laube, Anja Feldmann, et al. 10 February 2023 Detection of antigens and antibodies (Abs) is of great importance in determining the infection and immunity status of the population, as they are key parameters guiding the handling of pandemics. Current point-of-care (POC) devices are a convenient option for rapid screening; however, their sensitivity requires further improvement. We present an interdigitated gold nanowire-based impedance nanobiosensor to detect COVID-19-associated antigens (receptor-binding domain of S1 protein of the SARS-CoV-2 virus) and... read more https://doi.org/10.1021/acssensors.2c01686

Jacquat, Julien Riou, Dominik Menges et al. 17 February 2023 Effective public health measures against SARS-CoV-2 require granular knowledge of population-level immune responses. We developed a Tripartite Automated Blood Immunoassay (TRABI) to assess the IgG response against three SARS-CoV-2 proteins.

Possible contributions of the vehicle, sulfobutylether-β-cyclodextrin (SBECD) to Veklury® effects have been overlooked. The powder and ... read more https://doi.org/10.1111/bph.16063
P2020-001 Novel intranasal vaccine targeting SARS-CoV-2 receptor binding domain to mucosal microfold cells and adjuvanted with TLR3 agonist Riboxxim™ elicits strong antibody and T-cell responses in mice Reinhold Horlacher, Armin Günther, Alexander Brosig, Jenny Morath, Barbara Jakobs, Marcus Groettrup, et al. 21 March 2023 SARS-CoV-2 continues to circulate in the human population necessitating regular booster immunization for its long-term control. Ideally, vaccines should ideally not only protect against symptomatic disease, but also prevent transmission via asymptomatic shedding and cover existing and future variants of the virus. This may ultimately only be possible through induction of potent and long-lasting immune... read more https://doi.org/10.1038/s41598-023-31198-3
P2020-031 Omicron infection-associated T- and B-cell immunity in antigen-naive and triple-COVID-19-vaccinated individuals Joana Barros-Martins, Swantje I. Hammerschmidt, Gema Morillas Ramos, Anne Cossmann, Laura Hetzel, Ivan Odak, et al. 5 May 2023 Since early 2022, various Omicron variants have dominated the SARS-CoV-2 pandemic in most countries. All Omicron variants are B-cell immune escape variants, and antibodies induced by first-generation COVID-19 vaccines or by infection with earlier SARS-CoV-2 variants largely fail to protect individuals from Omicron infection. In the present study, we investigated the effect of Omicron infections in triple-vaccinated and in antigen-naive individuals. We show that Omicron breakthrough infections occurring... read more https://doi.org/10.3389/fimmu.2023.1166589
P2020-060 A novel ACE2 decoy for both neutralization of SARS-CoV-2 variants and killing of infected cells Alexandra Kegler, Laura Drewitz, Claudia Arndt, Cansu Daglar, Liliana Rodrigues Loureiro, et al. 13 June 2023 The coronavirus disease 2019 (COVID-19) pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) led to millions of infections and deaths worldwide. As this virus evolves rapidly, there is a high need for treatment options that can win the race against new emerging variants of concern. Here, we describe a novel immunotherapeutic drug based on the SARS-CoV-2 entry receptor ACE2 and provide experimental evidence... read more https://doi.org/10.3389/fimmu.2023.1204543
