Figure 1

SARS-CoV-2 viral proteome presentation at the molecular HLA class II level. The number of viral peptides presented by individual HLA is shown for (A) the entire SARS-CoV-2 proteome; (B). Spike protein (S protein); (C) Nucleocapsid protein (N protein); (D) Membrane protein (M protein); and (E) Envelope protein (E protein). The HLA frequency in four broad ethnic populations is shown (AFA, African Americans; API, Asian and Pacific Islanders; CAU, Caucasians; HIS, Hispanics). Bars are coloured according to HLA locus, as shown. HLA were included in the figure if they had a frequency of ≥ 1% in any haplotype distribution from the four broad population groups.
