Abstract:
Limiting dilution assay and ~(51)Cr-release assay were used to quantitate the pre-cursors of MAF-secreting T cells in lymph nodes or lymphoblast population of themice infected with Leishmania major(Lm).At lst and 4th week after infectionwith live Lm,the numbers of MAF-P in lymph nodes of resistant mice(CBA/T6)and susceptible mice(BALB/C)showed no significant difference but resistantmice had much more MAF-P than susceptible mice at 8th week.The effect ofantigen,interleukin-2 and irradiated syngeneic spleen cells on the detection of MAF-P were investigated、It was found that syngeneic spleen cells were an impor-tant factors for the assay of MAF-P of lymphoblasts but lymph nodes cells,and that the addition of both antigen and interleukin-2 can significantly increasethe number of MAF-P than antigen or interleukin-2 alone when the cells oflymph nodes were examined.
