Abstract

T cell immunity is central for the control of viral infections. To characterize T cell immunity, but also for the development of vaccines, identification of exact viral T cell epitopes is fundamental. Here we identify and characterize multiple dominant and subdominant SARS-CoV-2 HLA class I and HLA-DR peptides as potential T cell epitopes in COVID-19 convalescent and unexposed individuals. SARS-CoV-2-specific peptides enabled detection of post-infectious T cell immunity, even in seronegative convalescent individuals. Cross-reactive SARS-CoV-2 peptides revealed pre-existing T cell responses in 81% of unexposed individuals and validated similarity with common cold coronaviruses, providing a functional basis for heterologous immunity in SARS-CoV-2 infection. Diversity of SARS-CoV-2 T cell responses was associated with mild symptoms of COVID-19, providing evidence that immunity requires recognition of multiple epitopes. Together, the proposed SARS-CoV-2 T cell epitopes enable identification of heterologous and post-infectious T cell immunity and facilitate development of diagnostic, preventive and therapeutic measures for COVID-19.

  • This cross-reactivity largely originates from previous exposure to circulating common cold coronaviruses.

    “This cross-reactivity largely originates from previous exposure to circulating common cold coronaviruses [110-116].”

    From Guidelines for the use of flow cytometry and cell sorting in immunological studies (third edition) (2021) · cites this paper as [115]

    The ‘Cross-reactive T cell responses in unexposed individuals’ section reports pre-existing responses and similarities between recognized SARS-CoV-2 epitopes and seasonal common cold coronaviruses. The Discussion treats this as a basis for cross-reactivity, but the paper does not establish that previous exposure to those viruses accounts for most of it. (LLM, conf=0.85)

  • Lymphocytes from 20% to 50% of unexposed donors display significant reactivity to SARS-CoV-2 Ag peptide pools.

    “lymphocytes from 20% to 50% of unexposed donors display significant reactivity to SARS-CoV-2 Ag peptide pools (Figure 6).”

    From Guidelines for the use of flow cytometry and cell sorting in immunological studies (third edition) (2021) · cites this paper as [115]

    The Discussion reports SARS-CoV-2-reactive T cells in unexposed donors and notes earlier studies using peptide pools. But this paper reports responses in 81% of unexposed donors after 12-day pre-stimulation, not 20%–50%; its ex vivo analysis detected none of 42 unexposed donors. The claimed percentage is therefore not supported by this source. (LLM, conf=0.86)

  • T cell responses against SARS-CoV-2 are highly multi-antigenic and multi-specific, with tens of different epitopes recognized by CD4+ and CD8+ T cells in a given individual.

    “the T cell responses against SARS-CoV-2 are highly multi-antigenic and multi-specific, with tens of different epitopes recognized by CD4+ and CD8+ T cells in a given individual.”
  • Spike, M, and nucleocapsid are the most prominent targets of SARS-CoV-2-specific CD4+ T cells, with substantial responses also against ORF3a and nsp3.

    “Spike, M, and nucleocapsid are the most prominent targets of SARS-CoV-2-specific CD4+ T cells (Grifoni et al., 2020), with substantial responses also against ORF3a and nsp3 (Le Bert et al., 2020; Grifoni et al., 2020; Nelde et al., 2021; Oja et al., 2020; Peng et al., 2020).”

    From Adaptive immunity to SARS-CoV-2 and COVID-19 (2021) · cites this paper as Nelde et al., 2021

  • Multiple reports describe healthy individuals controlling SARS-CoV-2 infection with little to no detectable neutralizing or RBD IgG antibodies while having significant SARS-CoV-2-specific T cell memory.

    “Separately, there are multiple reports of healthy individuals successfully controlling a SARS-CoV-2 infection with little to no neutralizing (or RBD IgG) antibodies detectable post-infection, while having significant SARS-CoV-2-specific T cell memory (Rydyznski Moderbacher et al., 2020; Nelde et al., 2021; Schulien et al., 2020; Sekine et al., 2020).”

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.
