Endometriosis upregulated Myd88 in nociceptors. a–f Typical microscopic images of immunostaining for MyD88 co-expression with IB4, CGRP, and TRPV1 in rat DRG from sham and EM 14d groups. Scale bar 50 μm. g Parentages of Myd88⁺ cells in neurons with nociceptive markers (IB4, CGRP, and TRPV1) were increased in the EM 14d group compared with that in sham group. n > 100 neurons from 3 rats in each group, *p < 0.05, EM 14d vs sham, chi-square test
