在10日龄乳鼠和成年小鼠中,1型呼肠孤病毒选择性地附着和穿透膜上皮(M)细胞。为了确定M细胞何时首次出现,它们何时首次运输呼肠孤病毒,以及呼肠孤病毒在出生后第一周是否附着并被其他上皮细胞内吞,我们在1型呼肠孤病毒暴露后对新生小鼠的肠道进行了透射电子显微镜检查。2d时M细胞占穹隆上皮细胞的0.9%。第9天,M细胞已增加到7.4%。在2-6日龄的动物中,1型呼肠孤病毒在绒毛和穹隆上皮细胞表面的黏附表现出明显的变化,但到7日龄时,只有少数吸收细胞表面有黏附的呼肠孤病毒。除了2只动物外,所有的动物都有50%的M细胞黏附,但大多数Peyer‘s斑块吸收细胞图谱的黏附只出现在一些4天和5天大的动物身上。在所有年龄段的一些动物中,都会出现对大多数未分化细胞的黏附。膜上皮细胞在所有日龄都有呼肠孤病毒的内吞,但只有在2日龄时才有罕见的绒毛和穹隆吸收细胞将呼肠孤病毒内吞到顶端细胞质中。因此,呼肠孤病毒对新生小鼠粘膜上皮细胞顶端表面的黏附是非选择性的,但在出生后第一周变得更有选择性,到第7天时黏附到大多数M-CELI图谱,大量但数量可变的未分化细胞图谱,但对少数吸收细胞图谱。
In 10-day-old suckling and adult mice, reovirus type 1 adheres selectively to and penetrates membranous epithelial (M) cells. To determine when M cells first appear, when they first transport reovirus, and if reovirus adheres to and is endocytosed by other epithelial cells in the first postnatal week, we examined neonatal mouse intestine by transmission electron microscopy after reovirus type 1 exposure. At 2 days M cells accounted for 0.9% of dome epithelial cells. By 9 days M cells had increased to 7.4%. Reovirus type 1 adherence to the surface of villus and dome epithelial cells showed marked variation in 2–6-day-old animals, but by 7 days only a few absorptive cell profiles had adherent reovirus. Adherence to > 50% of M-cell profiles occurred in all but 2 animals, but adherence to the majority of Peyer's patch absorptive cell profiles was present only in some 4- and 5-day-old animals. Adherence to a majority of undifferentiated cell profiles occurred in some animals at all ages. Membranous epithelial cells endocytosed reovirus at all ages but only at 2 days did rare villus and dome absorptive cells endocytose reovirus into the apical cytoplasm. Thus, adherence of reovirus to the apical surface of mucosal epithelial cells is nonselective in newborn mice but becomes more selective within the first postnatal week with adherence by day 7 to most M-celi profiles, to a substantial but variable number of undifferentiated cell profiles, but to few absorptive cell profiles.
