70千道尔顿的氨基末端和180 kDa的细胞结合纤连蛋白片段被用来确定哪些纤连蛋白域支持可溶性明胶与巨噬细胞的相互作用。在每次测量时,完整的和180-kDa的纤连蛋白支持的细胞相关明胶的量显著大于对照水平(P< 0.05)。在整个时间过程中,纤连蛋白支持超过180 kDa的结合。70 kD分子量的蛋白质在2 h前不能增加明胶结合,但在6 h时,70 kD分子量的蛋白质比完整的纤连蛋白支持更多的结合(P< 0.01)。这似乎是由70 kDa明胶与巨噬细胞相互作用引发的细胞反应引起的。在4小时内,在对照条件下,并在纤连蛋白或180 kDa的存在下,与细胞相关的大部分明胶被内化。70千道尔顿介导的结合始终主要定位于细胞表面。巨噬细胞部分降解内化和外部明胶组分。这些结果表明,完整的纤连蛋白和特异性纤连蛋白片段支持可溶性明胶与巨噬细胞的相互作用。
Seventy-kilodalton amino-terminal and 180-kDa cell-binding fibronectin fragments were used to determine which fibronectin domains support soluble gelatin interactions with macrophages. At each time measured, intact and 180-kDa fibronectin supported significantly larger quantities of cell-associated gelatin than control levels (P< 0.05). Throughout the time course fibronectin supported more binding than 180 kDa. Seventy kilodalton did not augment gelatin binding until 2 h, but by 6 h 70 kDa supported more binding than intact fibronectin (P< 0.01). This appeared to result from a cellular response initiated by 70-kDa-gelatin interactions with the macrophages. Within 4 h the majority of gelatin associated with cells under control conditions, and in the presence of fibronectin or 180 kDa, was internalized. Seventy-kilodalton-mediated binding remained localized primarily to the cell surfaces at all times. The macrophages partially degraded the internalized and external gelatin fractions. These results demonstrate that intact fibronectin and specific fibronectin fragments support soluble gelatin interactions with macrophages.
