结论
2
DXXK具有显著的抗AS作用,抑制NLRP3炎症小体可能是其作用机制之一。
Objective
2
To investigate the effects of Di'ao Xinxuekang (DXXK) on NLRP3 inflammasome in mouse RAW264.7 macrophages and thoracic aorta of rats with atherosclerosis (AS), so as to explore its anti-AS mechanism.
Method
2
RAW264.7 cells were stimulated with oxidized low density lipoprotein (ox-LDL) and then intervened with MCC950 and DXXK. The contents of tumor necrosis factor-
α
(TNF-
α
) and interleukin-1
β
(IL-1
β
) were determined by enzyme linked immunosorbent assay (ELISA). The mRNA and protein expression levels of Nod-like receptor protein 3 (NLRP3), inflammasome adaptor protein apoptosis-associated speck-like protein containing CARD (ASC), and cysteine-dependent aspartate-directed protease-1 (Caspase-1) were detected by real-time polymerase chain reaction (Real-time PCR) and Western blotting. Sixty male SD rats were randomly divided into the normal group, model group, atorvastatin group (2.0 mg·kg
-1
), as well as high-, medium-, and low-dose (100, 30, and 10 mg·kg
-1
) DXKK groups, with 10 rats in each group. The rats were exposed to the high-fat diet and vitamin D
2
for inducing AS. The blood lipid level was measured using an automatic biochemical analyzer, followed by the calculation of AS index (AI). The contents of serum TNF-
α
and IL-1
β
were determined by ELISA, and the mRNA and protein expression levels of NLRP3, ASC, and Caspase-1 in thoracic aorta were assayed by Real-time PCR and Western blotting. HE staining and Sirius red staining were conducted to observe the pathomorphological changes in the abdominal aorta and aortic sinus.
Result
2
Compared with the normal group, the model group exhibited significantly increased TNF-
α
and IL-1
β
contents and up-regulated NLRP3, ASC, and Caspase-1 mRNA and protein expression in RAW264.7 cells (
P
<
0.01). The above indexes in each drug administration group were significantly reduced in contrast to those in the model group (
P
<
0.05,
P
<
0.01). The comparison with the model group showed that cholesterol (TC), triglyceride (TG), low-density lipoprotein cholesterol (LDL-C), and AI in each DXXK group significantly declined, while the high-density lipoprotein cholesterol (HDL-C) was significantly elevated (
P
<
0.05,
P
<
0.01). The levels of serum TNF-
α
and IL-1
β
and the mRNA and protein expression levels of NLRP3, ASC, and Caspase-1 in the thoracic aorta were decreased (
P
<
0.05,
P
<
0.01). Abdominal aortic lesions and fibrous hyperplasia of aortic sinus were significantly improved.
Conclusion
2
DXXK has a significant anti-AS effect, which is possibly related to the inhibition of NLRP3 inflammasome.
