Intracranial aneurysm (IA), characterized by distended blood vessels within the arteries, is a common vascular anomaly that frequently leads to cerebral blood vessel rupture, causing subarachnoid hemorrhage (SAH) with serious consequences.It has been found that, in addition to genetic factors, inflammatory responses induced by altered hemodynamics play a key role in the formation and rupture of IA. Subsequently, vascular inflammation can trigger a series of biochemical responses involving a variety of cells, including vascular smooth muscle cells, macrophages, lymphocytes, mast cells, and neutrophils, and involving several signaling pathways, including the PGE2-EP2-NF-κB signaling pathway, the JAK/STAT3/NF-κB signaling pathway, PI3K/Akt (PKB) signaling pathway, and AMPK/ACC signaling pathway. However, no clear conclusions have been made regarding the specific pathogenesis of IA, and immunotherapies targeting the pathogenesis of IA are still under basic research and not widely used in clinical practice. This review describes the cells, cytokines, and signaling pathways involved in the development of IA, in the hope that it will contribute to the understanding of the pathogenesis of IA and inspire the development and use of immunological drugs.
