AFP是胎儿血清和肝癌患者血清的重要组成成分,每毫升血清中浓度可达数毫克,而在成年人血清中仅几个毫微克。目前对AFP的生理功能了解甚少。巨噬细胞是一类重要的免疫活性细胞。在机体免疫防御方面起着重要作用,不仅与B细胞的抗体形成,T细胞的激活等有密切关系,而且还能合成和释放大量具有重要生理功能的生物高分子以及直接作用于
AFP is an important constituent of serum from fetal and hepatocellular carcinoma patients, with a concentration of up to several milligrams per milliliter serum, and only a few nanograms in adult serum. Little is known about the physiological function of AFP. Macrophages are a class of important immunocompetent cells. Plays an important role in the body’s immune defense. It not only has close relationship with antibody formation of B cells and activation of T cells, but also synthesizes and releases a large number of biopolymers with important physiological functions and acts directly on
