Abstract
SARS‐CoV‐2 specific T‐cell response has been associated with disease severity, immune memory and heterologous response to endemic coronaviruses. However, an integrative approach combining a comprehensive analysis of the quality of SARS‐CoV‐2 specific T‐cell response with antibody levels in these three scenarios is needed. In the present study, we found that, in acute infection, while mild disease was associated with high T‐cell polyfunctionality biased to IL‐2 production and inversely correlated with anti‐S IgG levels, combinations only including IFN‐γ with the absence of perforin production predominated in severe disease. Seven months after infection, both non‐hospitalised and previously hospitalised patients presented robust anti‐S IgG levels and SARS‐CoV‐2 specific T‐cell response. In addition, only previously hospitalised patients showed a T‐cell exhaustion profile. Finally, combinations including IL‐2 in response to S protein of endemic coronaviruses were the ones associated with SARS‐CoV‐2 S‐specific T‐cell response in pre‐COVID‐19 healthy donors’ samples. These results could have implications for protective immunity against SARS‐CoV‐2 and recurrent COVID‐19 and may help for the design of new prototypes and boosting vaccine strategies.

Results from LimitationRecognizer: We detected the following sentences addressing limitations in the study:One limitation of this study is that all patients included were recruited in the first wave of COVID-19 in Spain, in those dates, experimental therapies with very limited but transitory immunosuppressive effects were administered what may have affected the levels of immune parameters in acute infection. However, in those patients who were treated with IFN-β and corticosteroids, samples were collected time enough after these therapies to reverse the potential effects (24 days [7 – 28] and 9 days [1 – 21], respectively) what may have not affected the results presented herein. Seven months post-infection, one potential bias may come from the group of hospitalized subjects that were composed by patients with previous mild (42%) or severe (58%) disease, however, as no differences were found in any parameter associated to T-cell response (data not shown) between this two subgroups, they formed part of the same group of previously hospitalized and were compared with non-hospitalized patients. ICS needs a notable amount of cells to be assayed, this avoid us to perform endemic virus-specific T-cell response in COVID-19 samples; however, it has allowed us to obtain comprehensive data about the quality of SARS-CoV-2 specific T-cell response. Finally, anti-S IgG levels were assayed against the whole S protein and not for RBD, cross-reactive reaction cannot be excluded and results have to be interpreted taking this into account. In the same way, further research is needed to confirm and c...
