Abstract

Acute phase proteins (APPs) are produced mainly by the liver and their concentration is increased during the systemic inflammatory response. Expression of haptoglobin (Hp), serum amyloid A (SAA), lipopolysaccharide-binding protein (LBP) and α-1 acid glycoprotein (AGP) was determined in the mucosa of the normal bovine forestomachs and abomasum by qualitative and quantitative reverse transcriptase-PCR for mRNA and by Western blot analysis and immunohistochemistry for proteins. Although expression of SAA mRNA was evident in the forestomachs and abomasum, SAA protein was identified only in the abomasum. Expression of Hp protein was high in the forestomachs and abomasum, even though expression of Hp mRNA was negligible. The main site of expression of LBP mRNA was the omasum, whereas the highest protein expression was evident in the abomasum. AGP was expressed at low levels in the bovine forestomachs. Western blot analysis revealed a heterogeneous electrophoretic pattern for AGP, LBP and Hp, indicating that different stomach compartments produce isoforms that are different to those expressed by the liver. Expression of APPs by the bovine forestomachs and abomasum may contribute to regulation of the innate immune response against pathogens.
