| Research Abstract |
Complement regulatory factors (CD46, CD55, and CD59) were expressed in human periodontal ligament cells. The amount of CD59 expressed on human periodontal ligament cells stimulated with LPS from P. intermediais down-regulated by pre-treatment with TNF- . Anandamide (AEA), one of endocannabinoids, induced MMP-2 production in human dental pulp cells. MMP-2 might be cleave the complement regulatory factors from cells, and which receive complementary attack. It is likely that inflammatory mediatorssuch as TNF- and endocannabinoids such as AEA down-regulate the expression of complement regulatory factors and might be cause the tissue destruction inapical region.
