The treatment effect of ISCOM leukemia vaccine combination with 1-methyl tryptophan on tumor burden mice
摘要
Abstract
Objective Investigated the treatment effect of ISCOM leukemia vaccine combination with 1-methyl tryptophan on tumor burden mice .Methods Saponin was added lipase protein (1 mg/mL) 7 ℃ for 12 h ,adding 80 μL lipid mixed solution and 5 mL saponin solution (1 mg/mL ) to prepare ISCOM leukemia vaccine .C57BL /6 mice were randomly divided into model group , ISCOM leukemia vaccine group ,1-methyl tryptophan group and combination group ,Mice were injected FBL-3 cell to built leukemia tumor-burdened mice model .After treatment for 4 weeks ,tumors weight ,NK and Mφ and CTL cell killing activity ,serum levels of IL-10 ,IL-12 were detected .Results Tumor weight in combination group was less than 1-methyl tryptophan and ISCOM leukemia group [(0 .64 ± 0 .26)g vs .(2 .49 ± 0 .91)g ,P< 0 .01 ,(0 .64 ± 0 .26)g vs .(1 .28 ± 0 .73)g ,P< 0 .05] ;NK cell killing activity in com-bination group was higher than 1-methyl tryptophan group[(38 .41 ± 8 .27)% vs .(67 .22 ± 12 .74)% ,all P< 0 .01)] ;M φ activity in combination group was significantly higher than 1-methyl tryptophan group[(55 .69 ± 13 .69)% vs .(69 .47 ± 14 .79)% ,P< 0 .01] ;CTL activity in combination group was significantly higher than 1-methyl tryptophan group and ISCOM leukemia group[(43 .77 ± 8 .89)% vs .(69 .68 ± 11 .44)% ,P< 0 .01 ,(58 .87 ± 9 .45)% vs .(69 .68 ± 11 .44)% ,P < 0 .05] ;IL-10 in combination group were significantly lower than 1 - methyl tryptophan group and ISCOM leukemia group [(76 .2 ± 6 .82)pg /L vs .(98 .3 ± 13 .4)pg/L ,P<0 .01 ,(76 .2 ± 6 .82)pg/L vs .(202 .3 ± 44 .5)pg/L ,P < 0 .01] ;IL-12 in combination group were significantly higher than 1-methyl tryptophan group and ISCOM leukemia group[(381 .2 ± 47 .3)pg/L vs .(332 .1 ± 30 .2)pg/L ,P < 0 .05 ,(381 .2 ± 47 .3)pg /L vs . (291 .2 ± 17 .3)pg/L ,P< 0 .01] .Conclusion Combination with 1-methyl tryptophan and ISCOM leukemia vaccine has a well anti-tumor effect ,its mechanism may be through mediated and the expression of IL-12 and IL-10 .关键词
