摘要

In murine splenocytes, a primary antigen-specific antibody response is stimulated by 2-O-alpha-D-glucopyranosyl-L-ascorbic acid (AA-2G), a stable form of ascorbate, as described in our previous paper. We examined here the effect of nerve growth factor (NGF) on the antigen-specific antibody production in vitro augmented by AA-2G. NGF (greater than or equal to 10 ng/ml), which alone had no effect, enhanced the anti-sheep-red-blood-cell (SRBC) antibody response stimulated by AA-2G. The effect of NGF plus AA-2G or AA-2G alone was abrogated by the presence of castanospermine, an alpha-glucosidase inhibitor, suggesting that the active form of AA-2G is ascorbate. The repeated additions, but not one addition, of ascorbate also resulted in a synergism with NGF on the antibody production. These results suggest that NGF might be a cytokine which functions as a regulatory factor for ascorbate-dependent immune responses. [References: 29]
