目的
2
探讨洗心汤治疗阿尔茨海默病的可能作用机制。
方法
2
制备洗心汤含药血清,并采用CCK8法检测BV-2小胶质细胞存活率,筛选洗心汤含药血清及β-淀粉样蛋白
25-35
(Aβ
25-35
)干预浓度进行后续实验。实验将BV-2细胞分为对照组、模型组(Aβ
25-35
)、洗心汤含药血清组(Aβ
25-35
+洗心汤含药血清)、空白血清组(Aβ
25-35
+空白血清)培养24 h后,ELISA法检测细胞上清中白细胞介素1β(IL-1β)、环氧合酶2(COX-2)、精氨酸酶2(Arg-2)含量,免疫荧光染色检测离子钙结合衔接分子1(IBA1)、CD86、CD206蛋白水平,RT-PCR法检测细胞
IL

白细胞介素6(

)
、
白细胞介素10(

)mRNA表达。
结果
2
选用10%洗心汤含药血清及40 μmol·L
-1
浓度的Aβ
25-35
进行后续实验。与对照组比较,模型组细胞上清中IL-1β、COX-2含量,细胞中IBA1、CD86蛋白水平及
IL
-
1β、IL
-
6
mRNA表达均明显升高;上清中Arg-2含量及细胞CD206蛋白水平、
IL
-
10
mRNA表达明显降低(
P
<0.05或
P
<0.01)。与模型组比较,洗心汤含药血清组上述各指标均显著改善(
P
<0.01),而空白血清组差异均无统计学意义(
P
>0.05)。
结论
2
洗心汤可能通过调节小胶质细胞活化状态,抑制促炎因子、增加抗炎因子释放改善神经免疫炎症,从而抑制阿尔茨海默病的进展。
Objective
2
To explore the potential mechanism of
Xixin Decoction
(洗心汤, XD) in treating Alzheimer's disease (AD).
Methods
2
XD-containing serum was prepared, and the BV-2 microglial cell viability was assessed using the CCK8 assay to determine the optimal intervention concentrations of XD-containing serum and amyloid-beta
25-35
(Aβ
25-35
) for subsequent experiments. BV-2 cells were divided into four groups, control group, model group (Aβ
25-35
), XD-containing serum group (Aβ
25-35
+ XD-containing serum), and blank serum group (Aβ
25-35
+ blank serum). After 24 hours of culture, the levels of interleukin-1β(IL-1β), cyclooxygenase-2 (COX-2), and arginase-2 (Arg-2) in the supernatent were detected by ELISA. Immunofluorescence staining was performed to detect the protein levels of ionized calcium-binding adaptor molecule 1 (IBA1), CD86, and CD206. RT-PCR was used to analyze the mRNA expression of
IL
-
1β
, interleukin-6 (
IL
-
6
), and interleukin-10 (
IL
-
10
).
Results
2
The concentrations of 10% XD-containing serum and 40 μmol·L
-
¹ Aβ
25-35
were selected for subsequent experiments. Compared to the control group, the model group showed significantly increased levels of IL-1β and COX-2 in the supernatant, as well as elevated protein expression of IBA1 and CD86 and increased mRNA expression of
IL
-
1β
and
IL
-
6
, while exhibiting significantly reduced levels of Arg-2 in the supernatant, CD206 protein expression, and
IL
-
10
mRNA expression (
P
<0.05 or
P
<0.01). Compared to the model g
roup, the XD-containing serum group showed significant improvement in all these indicators (
P
<0.01), whereas no statistically significant differences were observed in the blank serum group (
P
>0.05).
Conclusion
2
XD may regulate microglial activation, inhibit pro-inflammatory factors, and enhance anti-inflammatory factor release, thereby improving neuroimmune inflammation and inhibiting the progression of Alzheimer's disease.
