Transcription levels of pattern recognizing receptors TLR2, 4, 9, and RAGE in the intestine and mesenteric lymph nodes of the preterm and term germ-free piglets. Transcriptions of TLR2 (A), TLR4 (B), TLR9 (C), and RAGE (D) were compared in the preterm (n = 6, gray columns) and the term (n = 6, white columns) germ-free piglets in the ileum, the colon, and the mesenteric lymph nodes. The results are presented as mean + SEM. The instances of statistical significance in the colon are denoted with asterisks (*P < 0.05 and **P < 0.01).
