摘要: Levels of IL-4, IL-5, TNF-alpha, and IFN-gamma were quantitated in the intestinal (afferent) efferent thoracic duct lymph rats during course (0 to 289 h) an infection with Trichinella spiralis. Intestinal was collected by cannulating ducts mesenteric lymphadenectomized animals. These studies showed that cytokines typical a Th2 type (IL-4 IL-5) Th1 (IFN-gamma) simultaneously detected first 8 days after infection. Worm expulsion (day 11 12) associated increased levels IL-4 IL-5 lymph. rose as early 15 20 h remained elevated throughout activity appeared 60 reached peak worm expulsion. Despite predominantly nature cytokine response, several cycles high low production A comparison between values no significant differences or suggesting contribution node However, TNF-alpha lower compared consumption. Adoptive transfer experiments protective CD4+CD45RC- cells primed gut for more rapid TH2-type response faster than primary In contrast, adoptive CD4+CD45RC+ Th1-type(IFN-gamma) response. demonstrate novel method measuring real-time changes active
