Abstract [en]
The Toll-like receptors (TLR) are vitally important pattern recognition receptors linking innate and adaptive immunity. Several single nucleotide polymorphisms (SNP) in human TLR genes have been associated with disease. There are few studies on associations between polymorphisms in TLR genes and disease in pigs, but the TLR2/TLR6 heterodimer is activated by Mycoplasma hyopneumoniae, and the expression of TLR2, TLR4, and TLR9 is modulated in the presence of different Salmonella serovars. Porcine TLR1, TLR6, and TLR10 are located in a cluster on the p arm of chromosome 8, while TLR2 resides on the q arm. Previously, we identified quantitative trait loci (QTL) for immune-related traits on pig chromosome 8, close to the KIT gene and the microsatellite S0225, respectively. In order to explore polymorphism in some TLR genes in European wild boars and domestic pigs, TLR1, TLR2, and TLR6 were sequenced in 25 wild boars, representing three populations, and in 15 domestic pigs of Hampshire, Landrace, and Large White origin. Similarly, TLR10 was sequenced in 15 wild boars and 15 domestic pigs. In TLR1 and TLR2, more SNP were present in the domestic pigs than in the wild boars. In TLR6, SNP numbers were similar in both animal groups, but the level of heterozygosity was higher in the domestic pigs than in the wild boars. In TLR10, again, more SNP were present in the domestic pigs, and a higher number of nonsynonymous SNP were detected in TLR10 compared to the other genes. This may suggest redundancy for TLR10 in pigs.
