TL;DR: Most convalescent plasma samples obtained from individuals who recover from COVID-19 do not contain high levels of neutralizing activity, and rare but recurring RBD-specific antibodies with potent antiviral activity were found in all individuals tested, suggesting that a vaccine designed to elicit such antibodies could be broadly effective.

TL;DR: In this article, the authors report on the humoral memory response in a cohort of 87 individuals assessed at 1.3 and 6.2 months after infection with SARS-CoV-2.
Journal ArticleDOI

TL;DR: In the absence of vaccination, antibody reactivity to the receptor binding domain (RBD) of SARS-CoV-2, neutralizing activity and the number of RBD-specific memory B cells remain relatively stable between 6 and 12 months after infection.
Journal ArticleDOI
The metabolic checkpoint kinase mTOR is essential for IL-15 signaling during the development and activation of NK cells

TL;DR: It is found that the metabolic checkpoint kinase mTOR was activated and boosted bioenergetic metabolism after exposure of NK cells to high concentrations of IL-15, whereas low doses ofIL-15 triggered only phosphorylation of the transcription factor STAT5.

TL;DR: The memory B cell response to SARS-CoV-2 evolves between 1.3 and 6.2 months after infection in a manner that is consistent with antigen persistence, and the antibodies they express have greater somatic hypermutation, increased potency and resistance to RBD mutations, indicative of continued evolution of the humoral response.
