Figure 2. Toll-like Receptor (TLR) mRNA expression in pig gastric mucosa.

Figure 2

Expression of TLR2 (A-C), TLR3 (D-F), TLR4 (G-I) and TLR5 (J-L) mRNA expression was determined in three sites of the gastric mucosa of piglets during the suckling period (14, 21 and 28 days of age) and after weaning (42 days of age).

TLRs expression was modulated during development in the oxyntic mucosa, where TLR2 decreased after weaning (P=0.038) and TLR4 linearly increased during suckling (P=0.008), and in the cardiac-to-oxyntic mucosa, where TLR2 linearly increased during suckling (P=0.003). For the three gastric sites, no significant quadratic effect during suckling was detected (P>0.05).
