1) In both maternal and autologous T and natural killer T cells, the expression of some important cytokines (e.g., GZMBaz)) against infections increases, while the expression of some transcription factors (e.g., FOSba)) related to lymphocyte activation, proliferation, and differentiation decreases. And many inhibitory factors (e.g., LAG3) showed augmented expression. This evidence concerns the gene LAG3 and infection.
