| The intravenous injection of concanavalin A (Con A) activates T cells and induces cytokine dependent liver injury in mice. However, the effect of repeated administrations of Con A has not been fully investigated. Female BALB/c mice were intravenously injected with Con A (20 mg/kg) or saline once a week for six times. Mice were rechallenged with Con A 17 days after repeated administrations of Con A. Repeated Con A administrations elicited a sustained inhibition of rechallenged-Con A-induced liver injury. Plasma TNF-alpha and IFN-gamma levels after rechallenge of Con A were decreased compared with that of repeated saline treatments. By contrast, plasma IL-4 and IL-10 levels after rechallenge of Con A were increased. In spleen cells prepared from repeated Con... |
