Strong cytotoxicity to human gingival fibroblasts by Porphyromonas gingivalis ATCC 33277.

abstract：:Previous observations suggest that interleukin-1 (IL-1) may play an important role in the progression of periodontitis. In the present study, we investigated whether a cell-associated IL-1 alpha (CAIL-1 alpha) produced in human gingival fibroblasts (HGF) induces biological activities related to the progression of peri...
