目的
2
观察利拉鲁肽(liraglutide)对局灶性脑缺血糖尿病大鼠缺血侧脑组织小胶质细胞/巨噬细胞极化及烟酰胺腺嘌呤二核苷酸磷酸氧化酶(nicotinamide adenine dinucleotide phosphate oxidase
NOX2)表达的影响。
方法
2
将75只大鼠按照随机数字表法分为脑缺血(CI)组、糖尿病脑缺血(DCI)组、胰岛素(Ins)组、利拉鲁肽(Lir)组和NOX2激动剂TBCA(tetrabromocinnamic acid)+利拉鲁肽(TBCA)组,每组15只。脑缺血后第3天行神经功能缺损评分; 2

5-氯化三苯四氮唑((TTC))染色测脑梗死体积; 免疫荧光双标染色检测小胶质细胞/巨噬细胞CD16/32、CD206与Iba1共标情况;Western blot检测NOX2、TNF-α、IL-1β、IL-10、TGF-β的蛋白表达。
结果
2
与DCI组相比,Lir组大鼠神经功能评分减少,脑梗死体积减小,同时M1型小胶质细胞/巨噬细胞Iba1

/CD16/32

细胞数减少,TNF-α、IL-1β、NOX2表达减少,而M2型小胶质细胞/巨噬细胞Iba1

/CD206
+
细胞数增多,IL-4、IL-10表达增多(
P

0.05)。
结论
2
利拉鲁肽的神经保护作用可能与其抑制NOX2表达,同时促进小胶质细胞/巨噬细胞向M2型转换有关。
Objective
2
To investigate the effects of liraglutide (Lir) on microglia/macrophage polarization and on the expression of nicotinamide adenine dinucleotide phosphate oxidase (NOX2) in the ischemic brain tissue of diabetic rats with focal cerebral ischemia.
Method
2
Seventy-five rats were randomly and equally divided into 5 groups: cerebral ischemia (CI) group
diabetes+cerebral ischemia (DCI) group
insulin treatment (Ins) group
Lir treatment (Lir) group
and NOX2 agonist tetrabromocinnamic acid (TBCA) + Lir group (TBCA). On the 3rd day after cerebral ischemia
the neurological deficit scores of the rats were evaluated
and 2
3
5-triphenyltetrazolium chloride (TTC) staining was adopted to measure the cerebral infarct volume in each group. The co-labeling of CD16/32 and CD206 with Iba1 on microglia/macrophages were detected by immunofluorescence double-label staining
and the protein expression of NOX2
TNF-α
IL-1β
IL-10 and TGF-β were determined using Western blotting.
Results
2
As co
mpared with the DCI group
the neurological deficit scores were decreased
and the cerebral infarction volume was reduced in the Lir group. The cell number of Iba1
+
/CD16/32
+
microglia/macrophage (M1 type) was declined
with down-regulated expression of TNF-α
IL-1β and NOX2 in the Lir group
while the number of Iba1
+
/CD206
+
microglia /macrophage (M2 type) was increased
with improved levels of IL-10 and TGF-β (all
P
<
0.05). However
the above effects were reversed by the treatment of NOX2 agonist TBCA (
P
<
0.05).
Conclusion
2
The neuroprotective effects of Lir on cerebral ischemic injury may be related to the inhibition of NOX2 expression and promotion of microglia/macrophages conversion to M2 type.
