The numbers of 'background' plaque-forming cells (PFC) secreting IgM specific for either sheep erythrocytes or horse erythrocytes were found to be elevated in the spleens of BALB/c mice during Plasmodium berghei and P. yoelii infection. 'Background' PFC numbers were similarly elevated in the spleens of uninfected mice injected with high speed supernatants of lysates of parasitized red blood cells. The active factor (or factors) in the supernatants was (were) non-dialysable and stable at 56 degrees C, but was (were) destroyed by heating to 100 degrees C.
发现在感染伯氏疟原虫和约氏疟原虫期间,BALB/c小鼠脾脏中分泌针对绵羊红细胞或马红细胞的IgM的“背景”噬斑形成细胞(PFC)数量增加。在注射了寄生红细胞裂解物高速上清液的未感染小鼠脾脏中,“背景”PFC数量同样增加。上清液中的活性因子不可透析,在56℃下稳定,但加热至100℃会被破坏。
