Abstract

In addition to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), humans are also susceptible to six other coronaviruses, for which consecutive exposures to antigenically related and divergent seasonal coronaviruses are frequent. Despite the prevalence of COVID-19 pandemic and ongoing research, the nature of the antibody response against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is unclear. Here we longitudinally profile the early humoral immune response against SARS-CoV-2 in hospitalized coronavirus disease 2019 (COVID-19) patients and quantify levels of pre-existing immunity to OC43, HKU1 and 229E seasonal coronaviruses, and find a strong back-boosting effect to conserved but not variable regions of OC43 and HKU1 betacoronaviruses spike protein. However, such antibody memory boost to human coronaviruses negatively correlates with the induction of IgG and IgM against SARS-CoV-2 spike and nucleocapsid protein. Our findings thus provide evidence of immunological imprinting by previous seasonal coronavirus infections that can potentially modulate the antibody profile to SARS-CoV-2 infection.

Figures

Fig. 1 Longitudinal antibody response to SARS-CoV-2 antigens. Serum from hospitalized COVID-19 patients was analyzed at baseline, at hospital recruitment and days 3 and 7. A subsequent sample was collected in the convalescence period in the COVID-19 survivors with mean time of 46 days. A Longitudinal profile of antibodies against SARS-CoV-2. Antibody titer was quantified as area under the curve (AUC) after serial serum dilution for each sample (Supplementary Fig. 1). Calculated AUC at each time is shown to quantify changes over time for each individual (small dots) against immunoglobulin G (IgG) spike, IgG receptor-binding domain (RBD), immunoglobulin M (IgM) spike and IgG nucleocapsid (N); and neutralizing activity (nAb) as inhibitory concentration 50% (IC50%). Geometric mean titer (GMT, big dots) and confidence interval (CI 95%) are also shown. B Boxplot diagram of geometric mean fold rise (GMFR) antibody titers against SARS-CoV-2 at the same time points: IgG spike, IgG RBD, IgM spike and IgG NP; and neutralizing activity (nAb). Related-samples Friedman’s two-way ANOVA was performed. Significant adjusted p values after pairwise comparisons are shown for each comparison. Black bar indicates GMFR values, box indicates IQR (Q1–Q3), lines indicate minimum and maximum. Outliers from the observed distribution are shown. Total n = 116 biologically independent serum samples (day 0 = 37, day 3 = 29, day 7 = 22, day 46 = 28). n = 116 biological samples examined against four different SARS-CoV-2 substrates for ELISA assays; ELISAs for each substrate were run once each. N = 116 serum samples examined over two independent experiments for neutralization assays.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
