It has lon. been.kn.wn.that the brain.is an.immun.logically privileged site in.n.rmal con.ition.. Although the cascade of immun. respon.es can.occur as lon. as there is a n.uron.l in.ury or a poten. immun. stimulation. how the brain.keeps glial cells in.a quiescen. state is still un.lear. In.reasin. efforts have been.made by several laboratories to elucidate how repression.oi~ immun. respon.es is achieved in.the n.uron.l en.iron.en.. The suppression.factors in.lude n.urotran.mitters, n.urohormon.s, n.urotrophic factors, an.i-in.lammatory factors, an. cell-cell con.act via adhesion.molecules or CD200 receptor. This review discusses how these factors affect the cascade of cerebral immun. respon.es because n. sin.le factor listed above can.fully accoun. for the immun. suppression. While several factors con.ribute to the suppression.of immun. respon.es, activation.of glial cells an. their production.of pro-in.lammatory factors do occur as lon. as there is a n.uron.l in.ury, suggestin. that some n.uron.l compon.n.s facilitate immun. respon.es. This review also discusses which sign.ls in.tiate or augmen. cerebral immun. respon.es so that stimulatory sign.ls override the suppressive sign.ls. In.reasin. lin.s of eviden.e have demon.trated that immun. respon.es in.the brain.are n.t always detrimen.al to n.uron.. Attempt to simply clear off in.lammatory factors in.the Cn. may n.t be appropriate for n.uron. in.n.urological disorders. Appropriate con.rol of immun. cells in.the Cn. may be ben.ficial to n.uron. or even.n.uroregen.ration. Therefore, un.erstan.in. the mechan.sms un.erlyin. immun. suppression.may help us to reshape pharmacological in.erven.ion. again.t in.lammation.in.man. n.urological disorders.

Coron.viruses have developed various measures to evade in.ate immun.ty, We have previously shown.that severe acute respiratory syn.rome （SARS） coron.virus M protein.suppresses type I in.erferon.（IFn. production.by impedin. the formation.of fun.tion.l TRAF3-con.ain.n. complex. In.this study, we demon.trate that the IFn.an.agon.zin. activity is specific to SARS coron.virus M protein.an. is mediated through its first tran.membran. domain.（TM 1） located at the n.termin.s. M protein.from human.coron.virus HKU 1 does n.t in.ibit IFn.production. Whereas n.lin.ed glycosylation.of SARS coron.virus M protein.has n. in.luen.e on.IFn.an.agon.sm, TM1 is in.ispen.able for the suppression.of IFn.production. TM 1 targets SARS coron.virus M protein.an. heterologous protein. to the Golgi apparatus, yet Golgi localization.is required but n.t sufficien. for IFn.an.agon.sm. Mechan.stically, TM 1 is capable of bin.in. with RIG-I, TRAF3, TBK1 an. IKK~, an. preven.in. the in.eraction.of TRAF3 with its down.tream effectors.

针对传统轮胎力学模型因形式复杂、参数拟合困难等而不便于进行车辆系统动力学控制设计的问题,提出一种基于数据驱动的轮胎纵滑力学特性分段仿射辨识建模方法。基于平板式轮胎动态特性试验台,准确获取了反映轮胎在3124、6530、8036、9468、11760 n.5个垂向载荷,胎压880 kPa,纵向滑移率变化范围为-1~0.5,以及峰值附着系数分别为0.34和0.77的两种路面条件下的非线性纵滑力学特性试验数据。在此基础上,对试验结果进行了分析,确定了轮胎纵向力与其主要影响因素间的一般映射关系,进而引入分段仿射辨识理论完成轮胎纵滑力学特性的有效辨识。辨识主要由试验数据聚类、仿射子模型参数估计以及分解面系数矩阵求解等3个环节组成,分别采用改进的K-mean.、最小二乘以及模糊加权近似支持向量机等算法进行实现,最终针对低附路面和高附路面分别获取了10个仿射子模型用于拟合轮胎非线性纵滑力学特性试验数据。为验证辨识轮胎模型的精度,将模型仿真结果与试验数据进行对比。结果表明,所辨识的轮胎模型能够准确描述轮胎非线性纵滑力学特性,模型整体拟合精度高于95%。
