ABSTRACT CD14, a pattern recognition receptor on monocyte and macrophage, plays a central role in innate immunity through recognition of bacterial lipopolysaccharide and initiation of


inflammatory response. Recently, CD14/−260C>T promoter gene polymorphism has been found to be related to a risk of inflammatory diseases. Our results showed that the C allele frequency


among Chinese in Taiwan was lower than those in Western countries. The membrane CD14 expression was significantly higher in TT as compared with CT and CC genotypes (_P_=0.034, 0.044,


respectively). There was a higher level of soluble CD14 in TT and CT genotypes than in CC genotypes. In addition, TNFα production in whole blood was significantly higher in TT genotype than


in CC genotype after stimulation by _Chlamydiae_. In conclusion, the single base pair polymorphism of CD14 promoter gene is associated with CD14 expression and Chlamydia-stimulated TNFα


production, and may thus play some role in the chlamydia-induced inflammatory response. Access through your institution Buy or subscribe This is a preview of subscription content, access via
