While the function of the OR2L13 (Olfr168) receptor with regard to platelet aggregation and its association with aneurysm has been examined, it may be useful to further investigate its function in relation to parameters such as aortic wall inflammation and inflammatory cell recruitment, as platelet activation can also lead to the secretion of factors that contribute to inflammation (MCP-1, β2-microglobulin) [240,241]. This evidence concerns the gene CCL2 and aneurysm.
