摘要
目的研究脑卒中后抑郁(PSD)大鼠海马小胶质细胞脑源性神经营养因子(BDNF)及其高亲和力受体酪氨酸蛋白激酶受体B(TrkB)蛋白的表达情况。方法将40只健康成年SD大鼠随机分为正常组、抑郁组、脑卒中组及PSD组,每组10只。用线栓法建立局灶性脑缺血模型;用慢性不可预见的中等应激刺激结合孤养法建立大鼠慢性应激抑郁模型。各组造模后第29和57天用免疫荧光双标染色法测大鼠海马OX42标记的小胶质细胞BDNF及TrkB表达情况。结果造模后第29天PSD组海马BDNF和TrkB阳性细胞吸光度(A)值分别为83.35±5.74和82.35±5.74,显著低于正常组、抑郁组和脑卒中组(P<0.05);抑郁组A值较脑卒中组增多(141.23±9.16 vs133.31±7.89;141.23±8.07 vs 128.62±6.92,P<0.05)。造模后第57天PSD组海马BDNF和TrkB阳性细胞A值分别为81.63±7.19,74.43±7.42,显著低于正常组、抑郁组和脑卒中组(P<0.05);脑卒中组A值较正常组及抑郁组低(93.36±7.56 vs 124.11±11.39、116.65±10.55,87.14±6.56 vs 112.58±10.99、108.05±10.57,P<0.05)。结论海马小胶质细胞在PSD发病过程中有重要意义,可能通过减少BDNF及TrkB的表达发挥作用。
