The duration of oral tolerance after a single feed of OVA at the age of 6 weeks was studied in BDF1 mice. Significant suppression of systemic antibody responses was present 3 months later, but not at 6.5 months; in contrast, at all times studied from 2 weeks to 17 months after an OVA feed there was suppression of systemic CMI to OVA as measured by an in vivo skin test. This indicates that the two limbs of the immune response differ in the factors responsible for the maintenance of oral tolerance.
在6周龄时单次喂食卵清蛋白(OVA)后,研究了BDF1小鼠口服耐受的持续时间。3个月后出现了对全身抗体反应的显著抑制,但6.5个月时未出现;相反,在OVA喂食后2周-17个月的所有研究时间点,通过体内皮肤试验测量发现,对OVA的全身细胞介导免疫(CMI)均受到抑制。这表明免疫反应的两个分支在维持口服耐受的因素方面存在差异。
