Data Statistics
Number of B-cell and T-cell epitopes against HCoVs
Currently, our database contains 66 210 B-cell epitopes, of which 1061 are
conformational, and 3209 T-cell epitopes, of which 1838 are HLA class I epitopes
and 1,101 are HLA class II epitopes. Statistical analysis shows that SARS-CoV and MERS-CoV possess
the largest number of B-cell epitopes, exceeding 15,000, followed by SARS-CoV-2 and HCoV-OC43,
surpassing 9,000, while others hover around 4,000. Notably, SARS-CoV-2 has the most conformational epitopes, totaling 971.
Moreover, SARS-CoV-2 has the largest count of T-cell epitopes, with 3,037, mainly located on
the Spike, ORF1ab, and N proteins. In contrast, other HCoVs display a significantly limited number of T cell epitopes.
Number of antibodies against HCoVs
CovEpiAb contains 12 613 antibodies against HCoVs.
Within this collection, 988 structures are available for 589 antibodies, and 6605 binding affinity records
and 62962 neutralizing activity records were investigated. The binding and neutralization
profiles of these antibodies against HCoVs and SARS-CoV-2 variants are listed here.
V and J gene usage of antibodies
We conducted an analysis on antibody gene usage and employed Sankey plots to illustrate the utilization patterns
of the top 50 most frequent V and J gene pairs in both antibody heavy and light chains.
The heavy chain V and J human genes most commonly used are IGKV3-30, IGHV1-69, IGHJ4, IGHJ6, and
the light chain V and J human genes most commonly used are IGKV1-39, IGKV3-20, IGKJ1 and IGLJ3.
-log fold change of neutralizing activity of therapeutics
We classify new coronavirus variants according to pango lineage and prevalence, including 64 currently circulating or
previously circulating variants. The database includes the virological characteristics of these variants, as well as
in vitro activity data of 108 therapeutics against the variants, including 55 vaccines, 34 neutralizing antibodies,
and 22 plasma samples from recovered patients, with a total of 10,158 in vitro activity records.
Analytical results indicate that recently identified Omicron subvariants, such as EG.5 and FL.1.5.1, exhibit greater
reductions in in vitro activity against various therapeutic agents compared with other variants. The most significant
reduction was observed in neutralizing antibodies.
Spike mutations resistant to therapeutic antibodies with emergency use authorization (EUA) or in advanced clinical trials
The mAb resistance mutations were defined as Spike mutations met one or more of the following criteria:
(1) having a median ≥5 fold reduction in susceptibility to a clinical stage mAb compared with wildtype according to
(CoV-RDB)
and/or (2) having >0.1 average antibody escape from aggregated deep mutational scanning data
(Starr et.al, 2021).
