Web组成型表达 （ constitutive expression ）： Expression of a gene that is transcribed at a constant level. 指表达是持续的，RNA及蛋白质表达量也相对恒定，不受时空条件改变而改变，也不因外界因素变化而诱导基因表达，不需要其他调节因子、RNA聚合酶与启动子 … WebTissue factor is constitutively expressed on the surface of many extravascular cells, such as fibroblasts and pericytes within the blood vessel wall, but not in cells within vasculature that contact blood, such as monocytes and endothelial cells. However, under certain pathological conditions, such as sepsis, monocytes/macrophages express TF.

WebMammalian cells constitutively express a cytosolic and nuclear form of heat shock protein (hsp) 70, referred to here as hsp 73. In response to heat shock or other metabolic insults, increased expression of another cytosolic and nuclear form of hsp 70, hsp 72, is observed. The constitutively expressed hsp 73, and stress-inducible hsp 72, are ... WebB cells = constitutively express MHC II but must be activated before expressing the CD80/86 costimulatory signal. Macrophages = must be activated before expressing either MHC II or the CD80/86 costimulatory signal. Give 3 examples of nonprofessional APCs.
