Effects of Xixin Decoction (洗心汤)-Containing Serum on BV-2 Microglial Activation and Immune Inflammation Induced by Aβ25-35
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.
