The female mice exhibited higher expression levels of CXCL2 (1A0, 6A4), PSMB8 (KO, 1A0, and 6A2), IFITM2 (KO), MYD88 (6A4), RSAD2 (KO, 6A4, and 1A3), SAMHD1 (KO, 6A2, and 6A4), STAT1 (KO, 6A2, and 6A4), STAT3 (KO, 6A2, 6A4, and 1A3), ZFP36L1 (KO, 6A4), and RTP4 (1A3) compared to males in response to infection (Figure 6). This evidence concerns the gene SAMHD1 and infection.
