【摘要】 Rho是小分子质量GTP酶Rho家族成员 ,在细胞的一些信号转导途径中起着分子开关的作用 .Rho能通过作用于肌动蛋白骨架系统引起轴突生长锥塌陷 ,从而抑制轴突生长 .研究表明 ,Nogo A、MAG、OMgp等髓鞘源性的轴突再生抑制分子均可通过激活Rho介导的信号转导途径抑制轴突再生 .

【Abstract】 Rho is a member of the Rho family of small GTPase, and acts as a molecular switch in some signal transduction pathway. Rho can induce growth cones collapse and inhibit axonal outgrowth by regulating the actin cytoskeleton. Recent studies have indicated that three myelin-derived inhibitors including Nogo-A,MAG and OMgp all can inhibit axonal regeneration by activating the Rho-mediated signal transduction pathway.
