抗氧化剂如二丁基羟基甲苯(BHT)、没食子酸丙酯(PG)和二甲基亚砜(DMSO)对体液免疫反应的影响是抑制体外抗体产生。这些抗氧化剂均抑制T依赖性B细胞反应,而不抑制T非依赖性和多克隆B细胞反应。这些数据表明,抗氧化剂通过抑制T细胞的调节或巨噬细胞对B细胞的作用而不是通过直接抑制B细胞来抑制体液免疫。抗氧化作用的另一种可能的解释是缺乏触发T依赖性抗原对B细胞应答所需的T-B细胞接触。
Effect of antioxidants on humoral immune responses, such as butylated hydroxytoluene (BHT), n-propyl gallate (PG) and dimethyl sulfoxide (DMSO) is suppression in vitro antibody production. These antioxidants all inhibited T-dependent B cell response, not T-independent and polyclonal B cell response. These data suggest that antioxidants suppress humoral immunity by suppression of regulation of T cells or action of macrophages on B cells, not by direct suppression of B cells. The other possible explanation for antioxidant action is the lack of T-B cell contact required for the triggering of the B cell response with T-dependent antigens.
