2.中新网广州2008年1月13日电：近日，一名慢性乙肝肝硬化患者在广东岭南肝病研究所进行自体骨髓干细胞移植获成功。目前，该患者肝功能各项指标恢复正常，从而达到骨髓干细胞变成肝细胞代行肝功能的治疗目的。下列叙述错误的是( )
A.乙肝病毒和不合理饮食都可能导致肝硬化
B.骨髓干细胞被移植到患者肝脏组织后，在肝脏微环境调节下“入乡随俗”地分化为肝细胞，但是遗传物质并未发生改变

D.干细胞之所以具有“因地分化”的特性，是由于基因表达过程中细胞能选择性地利用所含有的mRNA合成相应的蛋白质
1.据英国媒体BBC报道，诺贝尔奖得主著名生物学家巴尔的摩教授说，艾滋病病毒疫苗的研制工作经过了20多年后仍没有希望取得突破。巴尔的摩认为，由于艾滋病病毒进化出了可以从人类免疫系统中保护自己的方式，已经找到“愚弄”人类的免疫系统的方法。因此科学家试图以抗体或加强人类免疫系统来防御艾滋病病毒的方法都以失败告终。下列叙述错误的是( )
A.HIV能够侵入T细胞，导致患者的特异性免疫功能下降
B.科学家试图以抗体来防御HIV以失败告终的主要原因是患者体内无法产生与HIV特异性结合的抗体
C.HIV的遗传物质RNA易发生变异，是疫苗研制困难的原因之一
D.效应T细胞只选择性破坏已经被病原体感染的靶细胞
