In addition, a metabolic inhibitor, actinomycin D has no effect on enzymatic activities of caspase-1/ICE-like and caspase-3/CPP-32/like proteases during Fas-mediated CD4〓T cell apoptosis. These results indicate that the appearance of caspase-1/ICE-like and caspase-3/CPP32-1ike proteases activities is a post-translational activation of these proteases. It is likely these caspases constituently express in a inactive form in the cytosol of CD4〓T lymphocytes. Once the rest SEB-responsive CD4〓T cells are restimulted, those inactive caspases such as caspase-1/ICE-like and caspase-3/CPP32-1ike proteases are sequentially cleaved to become active forms, and the apoptotic signal is transducted to downstream signaling molecules, Finally leads to CD4〓T cells apoptosis.

另外，通过代谢抑制剂放线菌素D对超抗原SEB诱导静息SEB应答〓细胞凋亡过程中Caspase成员酶活性变化的研究表明Caspase-1／ICE样，Caspase-3／CPP32样胱氨蛋白酶并非新合成的信号分子，很可能以无活性方式组成性表达于静息SEB应答〓细胞胞浆，在超抗原SEB再次刺激诱导〓细胞凋亡早期，先后顺序活化，借以传递凋亡信号到下游信号分子，诱导〓细胞凋亡。

This phenomenon not only causes soil secondary productivity clination, water and soil erosion inside oasis but also creates downfalling or death for a great lot of natural vegetables at middle reaches of a river, downstream and desert outer oasis. It have artificial oasis lose a natural barrier and have to face desert s affection .

这不仅引起绿洲内部土壤的次生盐渍化、水土流失等一系列问题，还造成了河流中、下游及绿洲外围大量天然植的衰败、死亡，使得人工绿洲区直接面临荒漠侵袭。
