Summary: A study developed a netrin-1-responsive AAA-targeted nanoparticle loaded with metformin for the treatment of abdominal aortic aneurysms. The results showed that metformin can prevent AAA progression by inhibiting the phenotypic transformation of vascular smooth muscle cells.

Summary: The purinergic receptor P2X7 plays a crucial role in abdominal aortic aneurysm (AAA) development by modulating macrophage pyroptosis and inflammation. P2X7 is highly expressed in human AAA specimens and experimental murine AAA lesions. Inhibition or deficiency of P2X7 attenuates aneurysm formation in experimental murine models, while its activation promotes AAA development. Mechanistically, macrophage P2X7 activates the NLRP3 inflammasome and its downstream caspase-1 to initiate the pyroptosis pathway.

Summary: This study aims to investigate the role of scavenger receptor A1 (SR-A1) in the pathogenesis of abdominal aortic aneurysm (AAA) and found that its deficiency aggravates AAA development by suppressing immunoresponsive gene 1 (IRG1) and increasing inflammatory response. Restoration of macrophage SR-A1 can relieve AAA.

Summary: This study found that deficiency of lectin-like oxidized low-density lipoprotein receptor-1 (LOX-1) may not mitigate the development of abdominal aortic aneurysm (AAA), but rather increases the vulnerability of rupture by suppressing adventitial fibroblast proliferation and collagen synthesis.

Summary: A 3-butyl-1-dodecyl-imidazolium bromide ionic liquid was synthesized to aid in the exfoliation of ReS2 bulk crystal to produce nanosheets, which were then used to construct a photoelectrochemical immunosensor for detecting collagen III. The use of the ionic liquid improved the photocurrent response of the nanosheets and accelerated the separation of electron-hole pairs, enhancing the sensor's characteristics. This ReS2-based immunosensor showed promising results in clinical serum samples.

Summary: The study utilized multimodal microscopy techniques to investigate the impact of collagen fibril structure on platelet adhesion in abdominal aortic aneurysm tissues. The findings revealed that abnormal collagen fibrils inhibit platelet adhesion, providing insights into thrombosis or bleeding disorders.

Summary: This study investigates the role of circRNA in abdominal aortic aneurysms (AAA) and macrophages. The researchers found that hsa_circ_0087352, a circRNA, is up-regulated in human AAA specimens and is related to the inflammatory response in THP-1 macrophages. Further experiments revealed that hsa_circ_0087352 promotes IL-6 transcription and the secretion of inflammatory cytokines by sponging endogenous hsa-miR-149-5p in macrophages, potentially through the ERK/NF-kappa B pathway. Additionally, hsa_circ_0087352 overexpression induces apoptosis in human vascular smooth muscle cells. These findings suggest the potential of hsa_circ_0087352 as a biomarker and therapeutic target for AAA.

Summary: MFAP4 plays a crucial role in promoting the development of AAA by inducing macrophage-rich inflammation and MMP activity within the vessel wall. Its deficiency leads to reduced AAA incidence and ameliorates pathological changes in AAA, implicating regulation of monocyte influx and MMP production as key mechanisms.

Summary: The study showed that decreased expression of Nur77 is associated with accelerated development of AAA in mice. Activation of Nur77 by celastrol had beneficial effects against AAA. The detrimental effects of Nur77 deficiency were linked to increased macrophage infiltration and expression of pro-inflammatory cytokines and MMP-9 in AAA lesions.

Summary: Weakening of the aortic wall and immune response contribute to the development of AAA, and the inflammatory response is closely associated with aortic rupture. Infiltration of immune cells differs significantly between different samples. NFKB1 may be an important transcription factor in AAA and aortic rupture. CD19, SELL, and CCR7 have potential diagnostic value for AAA, while OAS3, IFIT1, and IFI44L may be predictive factors for aortic rupture.

Summary: A systematic review examined the correlation of abdominal aortic aneurysm expansion rates with serum circulating biomarkers, identifying specific biomarkers potentially useful for individualized surveillance of patients with increased AAA growth rates. Various biomarkers, including D-dimers, LDL-C, HDL-C, and genetic factors, were found to be significantly associated with AAA growth rates, suggesting a potential role for serum biomarkers in patient monitoring.
