Figure 2From: The innate immune response of equine bronchial epithelial cells is altered by training Relative mRNA expression of TLR1-9 in bronchial biopsies (A) and EBEC (B). Muscle tissue is used as a calibrator for TLR mRNA expression (muscle tissue = 1). Note that the profile of mRNA expression of TLR1-9 in bronchial biopsies and EBEC is similar, although the magnitude of TLR mRNA expression is amplified after in vitro culture of 4–6 weeks duration (first passage).Back to article page
