Atherosclerosis has an auto-immune component driven by self-reactive T and B cells. Identifying their antigenic drivers may lead to new diagnosis and treatment approaches. Here, we aim to identify immunogenic T cell epitopes derived from atherosclerosis-relevant proteins such as ApoB100 by studying the repertoire of peptides presented by HLA in human plaques. We used immunopeptidomics to identify peptides presented by HLA-DR molecules from plaques of patients that underwent endarterectomy surgery. We selected a set of 20 peptides derived from ApoB100 and studied the presence and cytokine profile of ApoB100-specific CD4 revealed significant CD4 We show that immunopeptidomics can be a valid approach to new discover antigens in atherosclerosis.

Akkermansia muciniphila (A. muciniphila) is an intestinal commensal with anti-inflammatory properties both in the intestine and other organs. The aim is to investigate the effects of oral administration of A. muciniphila on lipid metabolism, immunity, and cuff-induced neointima formation in hyperlipidemic APOE*3-Leiden (E3L).CETP mice. Hyperlipidemic male E3L.CETP mice are daily treated with 2 × 10 Four weeks of treatment with A. muciniphila exerts lipid-lowering and immunomodulatory effects, which are insufficient to inhibit neointima formation in hyperlipidemic E3L.CETP mice.
