KRT18 and aortic aneurysm, familial abdominal, 1: Due to the impact of our PI protocol on inflammation and CK-18 levels, we intended to capture early signs of fibrosis in the livers of AAA-1-immunized mice through a transcriptomic approach using NanoString® technology allowing the detection of 560 genes involved in inflammation/fibrotic processes together with conventional histology to detect collagen (Sirius red fast green staining).
