Objective To examine whether ischemic preconditioning (IPC) can protect neuron against delay.d death in CA1 subfield of hippocampus following reperfusion of a lethal ischemia in rats, and explore the role of p53 and bax in this process. Methods We examined the effect of IPC on delay.d neuron death, neuron apoptosis, expressions of p53 and bax gene in the CA1 area of hippocampus in the rats using HE staining, flow cy.ometry. RT-PCR, and immunohistochemistry.technique. Results IPC enhanced the quantity.of survival cells in the CA1 region of hippocampus (216±9 cells/0.72 mm2 vs. 30±5 cells/0.72 mm2, Py.ischemia/reperfusion (2.06%±0.21% vs. 4.27%±0.08%, Pxpressions of p53 and bax gene of hippocampus compared with ischemia/reperfusion without IPC. Conclusion IPC can protect the neurons in the CA1 region of hippocampus against apoptosis caused by.ische- mia/reperfusion, and this process may.be related to the reduced expressions of p53 and bax.

Both interleukin-2 (IL-2) receptor y.subunit and non-receptor ty.osine kinase Jak3 play.important roles in IL-2 phy.iological functions. Jak3 has been known to bind IL-2Ry.and the interaction is very.important for IL-2 signaling. In order to find the domains directly.involved in the interaction between IL-2Ry.and Jak3, various deletion mutants have been constructed
