Abstract:Soon after rats are infected with Listeria monocytogenes (LM), Listeria antigen- (LMA) responsive lymphocytes are delivered to the animal's thoracic duct. These LM-responsive lymphocytes can be restimulated in vitro by LMA to generate cells that have a potent cytolytic capability. The activation of LMA responsive lymphocytes is immunologically specific and dependent upon the activity of histocompatible accessory cells. Neither cell-free LMA nor LMA-pulsed allogeneic accessory cells can promote a significant cy… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
