Comparison of the expression levels of different surface markers in NK cells of COVID‐19 convalescent donors of different severities. (a) Expression of CD57, NKG2C and CD16 markers in asymptomatic, mild, moderate, severe convalescent donors and healthy donors. (b) Expression of NKp30, NKG2D and NKp46 markers in asymptomatic, mild, moderate, severe convalescent donors and healthy donors. (c) Expression of CD158b, CD158a, CD158e and NKG2A markers in asymptomatic, mild, moderate, severe convalescent donors and healthy donors. (d) Expression of CTLA4, TIGIT, TIM3 and PD1 markers in asymptomatic, mild, moderate, severe convalescent donors and healthy donors. Asymptomatic (n = 11), mild (=22), moderate (n = 6), severe (n = 1) convalescent donors and healthy (n = 6) donors. Each dot corresponds to an individual, and the mean with the standard error of the mean (SEM) is shown. Student's t‐test was used to analyse the data. p‐value: *p  <  0·05, **p  <  0·005, ***p  <  0·001. ****p  <  0·0001
