SARS-CoV-2-specific CD4+ T cells were detected in almost all convalescent COVID-19 samples by AIM (14/15; Figure 2C), with consistent responses against S, M, N, and MP_R (Figure 2A), matching our previous cohort of convalescent COVID-19 cases (Grifoni et al., 2020a). The gene discussed is CD4; the disease is COVID-19.
