(A) Gating strategy for the enumeration of natural killer (NK) and natural killer T-like (NKT-like) cells in different study groups. Lymphocyte gate was recognized by forward scatter (FSC) & side scatter (SSC). Further, the CD3 negative cells from this population were screened for CD56+ expression to identify the NK cells and were identified as CD3-CD56+ and NKT-like (NKT-like) cells were CD3+CD56+. (B) Gating strategy for the enumeration of B and memory B cells in different study groups. B cells from lymphocytes were identified with the help of CD19 expression. For further differentiation, expression of CD27 was considered as memory B cells.
