Reactions in the periodontium to continuous antigenic stimulation in sensitized gnotobiotic rats.

abstract：:Transforming growth factor beta (TGF-beta) has been shown to be a central immunomodulator used by leishmaniae to escape effective mechanisms of protection in human and murine infections with these parasites. However, all the information is derived from studies of established infection, while little is known about TGF-...
