Abstract:
Objective: To study the possible role and way of ALR in the immune regulation in vitro. Methods: The proliferation of spleen mononuclear cells of rat was detected with 3H-TdR method in vitro under the following different treatments:(1)the administration of the different concentration of rALR with 5 ?g/ml ConA at same time;(2)the addition of 30 ?g/ml ALR after 5 ?g/ml ConA pretreatment in 10 h and 32 h, respectively;(3)the addition of 5 ?g/ml ConA after 30 ?g/ml ALR pretreatment until 30 h. Cyclosporin A and the supernatant from cultures of yeast were used as positive and negative controls, respectively. The IL-2 levels in the supernatants from the mononuclear cells by various treatments were detected with RIA test kit. Results: rALR inhibited the proliferation and the production of IL-2 of the mononuclear cells from rat spleen stimulated by ConA dose-dependently. The mononuclear cell proliferations were still inhibited by 30 ?g/ml rALR after stimulated by ConA for 10 h or 32 h, but the pretreatment of 30 ?g/ml rALR for 30 h had no influence on the reactivity of mononuclear cell to ConA compared with control. Conclusion: rALR could inhibit in dose-dependent way the proliferation of mononuclear cells from rat spleen stimulated by ConA in vitro, but it couldn’t influence the rest mononuclear cells. This suggests that the rest mononuclear cells might not express the receptor of ALR.
