Study of synergistic effects of Spirulina platensis on inducing IL-2 / 中国海洋药物

ABSTRACT

It has been shown that Spirulina platensis can regulate imminological functions.We report here that crude extract and purified components (phycocyanin and polysaccharide) from Spirulina platensis can induce secretion of IL 2 in splenocyte of BALB/C mice by means of MTT method.In the present study,we showed that all experimental components can't enhance proliferation of CTLL which was used in MTT method,but induce IL 2 secretion in splenocyte of BALB/C mice in three different concentration (0.01,0.1,1 g?L -1 ).Indeed the purified components especially phycocyanin part showed stronger IL 2 inducing activity than the crude one.IL 2 level was grow up when the incubation time of splenocyte and Spirulina platensis increased.In the concentration of 1 g?L -1 ,detected Spirulina platensis in our study assist IL 2 inducing of ConA (2mg?L -1 ) in splenocyte of BALB/C mice.
