Fig. 5: The composition of SARS-CoV-2 response in each individual is shown as a percentage of the total detected T cell response.
From: Immune memory in convalescent patients with asymptomatic or mild COVID-19

a The composition of SARS-CoV-2-specific CD4+ T cell response (OX40+CD137+) in individuals. b The composition of SARS-CoV-2-specific CD8+ T cell response (CD69+CD137+) in individuals. The percentage of S, M, and N-specific CD4+ or CD8+ T cell response was shown as median (IQR), and were performed by using two-sided Mann–Whitney U test. S, spike; M, membrane; N, nucleocapsid. RS, individuals recovered from COVID-19 with symptoms (n = 20); RA, individuals recovered from asymptomatic (n = 13); HC, healthy controls (n = 10).
