Damage-associated molecular patterns (DAMPs) in vascular diseases.

Area of Science:

• Cardiovascular Biology
• Immunology
• Molecular Medicine

Background:

• Chronic sterile inflammation is increasingly recognized as a key driver of vascular disease progression.
• Damage-associated molecular patterns (DAMPs) act as crucial mediators, linking cardiovascular risk factors to inflammatory responses.
• Understanding DAMPs and their signaling is vital for developing novel therapeutic strategies.

Purpose of the Study:

• To review the role of DAMPs and their associated receptor signaling pathways in vascular disease.
• To summarize how DAMPs contribute to pro-inflammatory cytokine release and vascular remodeling.
• To discuss the clinical implications and future directions for targeting DAMPs in vascular pathologies.

Main Methods:

• Literature review of studies on DAMPs and vascular disease.
• Analysis of signaling pathways including TLRs, RAGE, cGAS-STING, and NLRP3 inflammasome.
• Examination of pre-clinical and clinical trial data targeting DAMPs.

Main Results:

• DAMPs activate key signaling pathways that promote inflammation and vascular remodeling.
• Specific DAMP-mediated pathways are implicated in atherosclerosis, fibrosis, aneurysm, ischemia, and hypertension.
• Targeting DAMPs has shown potential in pre-clinical and clinical studies.

Conclusions:

• DAMPs are central players in sterile inflammation underlying vascular diseases.
• Modulating DAMP signaling pathways offers a promising therapeutic avenue for vascular conditions.
• Further research and clinical trials are warranted to fully exploit the therapeutic potential of targeting DAMPs.
