Alveolar bone resorption induced by CD4+CD45RB high-density T-cell transfer in immunocompromised mice.

abstract：BACKGROUND:Periodontitis is an infection with an episodic pattern of tissue-support destruction. During the generation of a primary CD4(+) T helper 1 (Th1) response, interferon-gamma (IFN-gamma) acts as a positive regulator by selectively inducing Th1 differentiation through increased transcription of T-bet. The aims o...
