(A-E) Chemokines linked to COVID-19 are induced by the S1 subunit of the SARS-CoV-2 spike protein. The same culture supernatants described in Figure 1 were also assayed for the indicated chemokines using multiplex analysis. Box-Whisker plots (Tukey’s method) represent results from different donor cell preparations (n=7). Responses to spike protein components were tested for significance by comparing to medium/IL-3 controls. **P<0.01, *P<0.05.
