Three fractions of Nocardia, Nocardia water-soluble mitogen (NWSM), Nocardia water-soluble mitogen pellet (NWSMP), and the cell wall peptidoglycan, which are mitogenic for B lymphocytes, were able to induce circulating interferon in mice, NWSMP and NWSM being the most active. The peak of interferon appeared about 2 h after injection. The interferon induced by NSWMP and NWSM was acid stable and antigenically related to viral interferon, as shown by neutralization with antibodies directed against Newcastle disease virus-induced interferon.
诺卡氏菌的三个组分,即诺卡氏菌水溶性促细胞分裂原(NWSM)、诺卡氏菌水溶性促细胞分裂原沉淀(NWSMP)以及对B淋巴细胞有促有丝分裂作用的细胞壁肽聚糖,能够在小鼠体内诱导循环干扰素,其中NWSMP和NWSM最为活跃。干扰素峰值在注射后约2小时出现。如用抗新城疫病毒诱导的干扰素抗体进行中和试验所示,NWSMP和NWSM诱导产生的干扰素对酸稳定,且在抗原性上与病毒干扰素相关。
