Immune Evasion of SARS-CoV-2 Emerging Variants: What Have We Learnt So Far?

PMID: 34206453 2021 Viruses

Introduction: Five mutations are located within NTD (L18F, T20N, P26S, D138Y, R190S), three in RBD (K417T, E484K, N501Y), two in the C-terminal domain of S1 and near the furin cleavage site (D614G, H655Y), and one in S2 (T1027I) (Figure 3).

Genomic monitoring unveil the early detection of the SARS-CoV-2 B.1.351 (beta) variant (20H/501Y.V2) in Brazil.

Result: P.1 defining mutations related to each genomic region were the following: ORF1ab: S1188L, K1795Q, E5665D; spike: L18F, T20N, P26S, D138Y, R190S, K417T, E484K, N501Y, H655Y, T1027I; Orf8: E92K; and nucleocapsid: P80.

Result: Eighteen patients with this N440K replacement were identified, and 10 patients had the identical combination of spike amino acid replacements: L18R, T95I, R158S, N440K, D614G, P681H, A688V, S735A, and T1027I.

Resistance of SARS-CoV-2 variants to neutralization by monoclonal and serum-derived polyclonal antibodies.

PMID: 33664494 2021 Nature medicine

Method: Amino acid substitutions for B.1.1.7, P.1 (Brazilian lineage: L18F, T20N,

Result: Given these results with viruses encoding E484K mutations, we performed separate studies with human convalescent serum (n =10) and a chimeric SARS-CoV-2 WA1/2020 strain encoding a Brazilian variant spike gene (Wash BR-B.1.1.248; L18F, T20N, P26S, D138Y, R190S, K417T, E484K, N501Y, D614G, H655Y, T1027I, and V1176F [Extended Data Fig 5a]).

Modelling conformational state dynamics and its role on infection for SARS-CoV-2 Spike protein variants.

PMID: 34351895 2021 PLoS computational biology

Result: P.1 variant includes the mutations L18F, T20N, P26S, D138Y, R190S, K417T, E484K, N501Y, D614G, H655Y, T1027I.

Mutation hotspots and spatiotemporal distribution of SARS-CoV-2 lineages in Brazil, February 2020-2021.

Table: T1027I

Discussion: Of the 10 new amino acid mutations in the spike protein (L18F, T20N, P26S, D138Y, R190S, K417T, E484K, N501Y, H655Y, T1027I) compared to its immediate ancestor (B.1.1.28), molecular selection analyses found evidence that 8 of these 10 mutations are under diversifying positive selection.
