During vascular inflammation commonly associated with aging, atherosclerosis, diabetes and autoimmunity, a range of biological, environmental and physical stressors can induce activation and apoptosis of ECs. Apoptotic bodies (ApoBDs) are large (~ 1-5 μm), membrane‑bound extracellular vesicles generated solely through apoptotic cell disassembly, that are increasingly recognised as mediators of intercellular communication via the transfer of bioactive molecules to target cells. Although EC apoptosis is a central feature of vascular inflammatory disorders, the formation of EC‑derived ApoBDs and their immunomodulatory roles when formed in an inflammatory environment, remains poorly defined. This study aimed to characterise the functional properties of EC‑derived ApoBDs generated under inflammatory conditions in vitro. A proteomics analysis of EC‑derived ApoBDs revealed that EC‑ApoBDs generated during inflammation ('iApoBDs') were enriched in inflammatory cytokines/chemokines, adhesion molecules and antigen presentation machinery compared with non-inflammatory ('ApoBD') controls. Functionally, iApoBDs promoted monocyte chemotaxis via the release of MCP-1, while altered expression of the adhesion molecule ICAM-1 enhanced efferocytosis by macrophages in vitro and in vivo. Furthermore, iApoBDs generated from antigen-pulsed HUVECs promoted IFN‑𝛾 expression by peptide specific CD8 T cells in an in vitro model of antigen presentation. These findings demonstrate that within an inflammatory setting, apoptotic ECs can participate in continued communication with their environment via the generation of ApoBDs, thereby modulating innate and adaptive immune processes. The formation of ApoBDs by ECs may serve as a target for therapeutic interventions in inflammatory vascular diseases.</p>","PeriodicalId":55268,"journal":{"name":"Cell Communication and Signaling","volume":"23 1","pages":"418"},"PeriodicalIF":8.2,"publicationDate":"2025-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12502297/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145245848","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Specifically, asymmetric dimethylation of PI3KC2α at the R175 residue (R175me2a) by coactivator-associated arginine methyltransferase 1 (CARM1) enhances its interaction with α-tubulin, stabilizing microtubule assembly.

The COVID-19 pandemic underscored the urgent need for treatments targeting systemic inflammation.

These EVs imitate many of the regenerative and immunomodulatory effects of MSCs, making them a promising cell-free therapeutic option.

The primary cilium responds to environmental stimuli, such as mechanical, chemical, or light (in the case of the modified cilium of photoreceptors) signals. The membrane of primary cilia host specific sensory complexes and/or receptors associated with various pathways, predisposing them to transmit (or convert) spatiotemporal environmental information into cellular response. These dual mechanochemical aspects led to the recognition that primary cilia are multifunctional sensory organelles that act as \"cellular antennae\". Beyond their established role in signal transduction, primary cilia are newly recognized as important hubs for short- and long-distance intercellular communication due to their ability to release and, perhaps, selectively take up extracellular vesicles, which are biological carriers exchanged between cells. In addition, the physical contact of the primary cilium with other cilia, cytonemes or with nerve cell axons adds another layer of complexity to the mechanisms of sensory and/or intercellular communication between neighboring cells that needs to be further explored.
