Abstract
Alsophila spinulosa (Cyatheaceae) has been used in Asia as a herbal medicine, In this study, the immunomodulatory effects of Alsophila spinulosa dried sterns water extract fraction VII (AS-VII) were studied in vitro using an animal model. The results showed that AS-VII stimulated splenocyte proliferation in both BALB/c and C3H/HeJ mice. By cell fractionation analysis, the results showed that the mitogenic effect of AS-VII was predominantly on B cell population. The antibody response was also augmented by AS-VII in BALB/c and C3H/HeJ mice. The augmentation of immune responses in C3H/HeJ, the lipopolysaccharide (LPS)-hyporesponsive mouse strain, indicated that the activity was not simply due to the LPS contamination which may be present in AS-VII preparation. Furthermore, AS-VII caused an increase in cytotoxic T cell activity in a mixed lymphocyte reaction culture. These data indicate that AS-VII possesses the capability of augmenting both humoral and cellular immune responses.
