IL12, IL10, IFNγ and TNFα expression in human primary monocytes stimulated with bacterial heat shock GroEL (Hsp64) protein
MetadataShow full item record
Actinobacillus (Aggregatibacter) actinomycetemicomitans (Aa) is a bacterium that lives in the oral cavity and plays an important role in periodontal diseases. The effect of A.actinomycetemcomitans's heat shock family protein GroEL on host or immune cells including monocytes is quite limited. In this study, the recombinant A.actinomycetemcomitans's GroEL protein (rAaGroEL) was used as an antigen and its effects on monocytes of peripheral blood mononuclear cells (PBMCs) was investigated. To do that, PBMCs were stimulated with rAaGroEL protein at different time points (16h to 96h) and the cytokines of CD14+ monocytes were detected with intracellular cytokine staining by Flow cytometry. Data showed that AaGroEL protein has an antigenic effect on human primary monocytes. AaGroEL protein responsive CD14 monocytes stimulates the expression of IL12, IL10, IFNγ and TNFα cytokines with different kinetics and expression profile. Therefore, A. actinomycetemcomitans's heat shock GroEL protein can modulate innate and adaptive immune responses and contribute to an inflammatory diseases pathology.
