Decreased Toll-like receptor-2 messenger ribonucleic acid and increased Toll-like receptor-4 in the tubal epithelium next to the infiltrated trophoblasts during tubal pregnancy

Decreased TLR2 mRNA and increased TLR4 in the tubal epithelial cells next to the infiltrated trophoblasts may be associated with aspects of the pathophysiology of tubal ectopic pregnancy in immune defense.
