Consistent with Woodruff et al.113, Kaneko et al.112 also reported increased levels of extrafollicular IgDCD27 B cells, which are also found in autoimmune diseases such as SLE, in their COVID-19 post-mortem lymph node and spleen samples. As such, we have opted to use the preprint date, where available, instead of theofficial publication date for the chronology of the studies that we highlight in our timeline of key discoveries during the first year of the pandemic (Fig. Haas, M. (2000). By contrast, patients with MIS-C develop a distinct set of autoantibodies to MAP2K2 and to three members of the casein kinase family (CSNK1A1, CSNK2A1 and CSNK1E1)53. In addition, another study preprinted in July 2020 found that antibodies to La (the autoantigen of systemic lupus erythematosus (SLE) and Sjogrens disease) and to Jo-1 (the autoantigen of idiopathic inflammatory myopathies) were found in patients with MIS-C54, suggesting the autoimmune nature of this syndrome.

Unfortunately, the FDA guidelines for allowing commercial tests to be marketed in the USA were initially very flexible, with a similarly wide use of commercial tests in many countries around the world28, leading to a flood of underperforming assays and confusion over seroprevalence estimates.

The virus, later termed severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), is the third betacoronavirus to cause an outbreak in humans this century (Box1). The virus seemed to have potentially adapted to mink by introducing a Y453F mutation into the spike protein RBD (in addition to other mutations). Hoodless, P. A. 1). Zhu, N. et al. What if we could clean them out? The role of the immune system not only in host protection but also in the pathogenesis of severe COVID-19 was highlighted by similarities with the systemic inflammatory syndromes of haemophagocytic lymphohistiocytosis (HLH) and cytokine release syndrome (CRS)38,39.
