บทคัดย่อ: Mice were infected with 8- or 25-infective worms of advanced third stage Gnathostoma spinigerum larvae (L3) which were obtained from natural infected eels. On day 14, 60 and 200 post infections (PI), spleen cells of infected mice were tested for lymphoproliferative responses in vitro against the mitogen and specific L3 somatic antigen in order to clarify the cellular immune status of the host upon this nematode infection. Reduced responsiveness to Con A was observed in infected mice. These depressed responses were more pronounced in chronically infected mice (day 200, PI) than in day 14 and day 60, PI. There was no significant difference of lymphoproliferative response between groups of high (25 L3) and low (8 L3)-infective dose in the chronic readily stage. Regarding to the L3 somatic Ag stimulation, the depressed response was obviously detected in high dose and chronic infection. Our results demonstrated that in this G. spinigerum-mouse system T-cell response is defective. The depression could be reversible and was associated with active infection because it was abolished by anthelmintic (ivermectin) treatment. This study shows the involvement of Th-2 response to this nematode in regulating T cell proliferation. © 2012 Elsevier Inc.
