伤严生，买验组注射抗IG'T的单克隆抗体阻断G'1抑制通路，抗G'I的单克隆抗体能够与TIGIT特异性结合使TIGIT无法与肝脏细胞表面信号分子结合，从而阻断TIGIT对T细胞活性的抑制。(3)①根据题干信息，血清中谷丙转氨酶的含量可作为检测肝脏细胞损伤程度的指标，第3组的谷丙转氨酶的含量低，说明第3组肝脏细胞无损伤，所以与第1组结果对比可知，第3组小鼠的肝脏处于免疫耐受状态。②第4组小鼠血清中谷丙转氨酶(ALT)含量最高，说明肝脏发生了损伤，损伤原因是TIGIT单抗可使乙肝模型小鼠中的T细胞对HBV抗原的免疫抑制解除，导致机体细胞免疫应答增强，从而引发肝脏受损。25.(12分)(1)避免顶芽产生的生长素对侧芽的生长造成影响，排除对实验结果的干扰(2分)(2)a>b(1分)能(1分)·能(1分)(3)可以为进一步的实验摸索条件，也可以检验实验设计的科学性和可行性(2分)(4)c浓度之前（或“小于c浓度”，或“0~c浓度”）(1分)》(5)若Y2小于Y1,则NAA的浓度为低浓度(A)(2分)；若Y2大于Y:,则NAA的浓度为高浓度(B)(2分)【详解】(1)顶芽能产生生长素，运输到侧芽，导致侧芽生长都浓度较高，抑制侧芽生长，因此用带顶芽的葡萄茎段实验时，要去除顶芽，避免顶芽产生的生长素对侧芽的生长造成影响，排除对实验结果的干扰。(2)生长素生理作用特点是低浓度促进生长，高浓度抑制生长，通过a、b、c与空白对照相比，对葡萄茎段的侧芽生长具有促进作用的是b、c浓度，具有抑制作用的是a浓度，因此a、b、c三种浓度中，NAA溶液浓度最高的是a,即a浓度大于b浓度。在a浓度的NAA溶液作用下.葡萄茎段侧芽能生长，只不过生长速度低于空白对照组。通过与空白对照相比，甲图所示的实验结果能体现NAA低浓度时促进生长.高浓度时抑制生长。(3)在进行科学研究时，有时需要在正式实验前先做一个预实验，这样可以为进一步的实验摸索条件，也可以检验实验设计的科学性和可行性，避免浪费。(4)如图所示，b、c浓度在X浓度两侧有4种可能性，即b
