Thy-1.1~+ OT-I CD8 T cells were adoptively transferred into Thy-1.2~+ host C57 mice treated with either isotype or PK136 Ab as mentioned above followed by injection i.v.withΔactA LM-OVA.On day 7 after infection,equal number of Thy-1.1~+ CD8 T effector cells from either hosts were sorted and adoptively transferred into second host mice(Thy-1.2) which were also on day 7 after infection and treated with isotype or PK136 Ab,respectively.

为进一步阐明NK细胞促进CD8Tm细胞的产生是作用于收缩期而不是扩增期，我们设计了如下的实验：将Thy-1.1~+ OT-I CD8 T细胞过继回输到经PK136抗体或对照抗体处理的C57小鼠体内并用ΔactA LM-OVA感染，7天后将两组小鼠脾脏中的Thy-1.1~+ CD8T细胞分离纯化后等量分别回输到同步感染的经PK136抗体或对照抗体处理的第二受体小鼠体内。

Identification and forecasting for igneous rock is one hard problem of exploration activity, because it has extreme aeolotropism. By firstly synthetically utilizing seismic analysis, well logging restricted inversion, core well core and electric log analysis method and so on, the igneous rock reservoir of Gaoqing oilfield is effectively identified and divided into one to four four phases according to igneous rock erupting phase.
