Innate immunity, Toll-like receptors, and atherosclerosis: mouse models and methods.
Chronic inflammation and aberrant lipid metabolism represent hallmarks of atherosclerosis. Innate immunity critically depends upon Toll-like receptor (TLR) signalling. Recent data directly implicate signalling by TLR4 and TLR2 in the pathogenesis of atherosclerosis. The role that TLRs play in the pathogenesis of atherosclerosis can be assessed by using several animal models, which provide a double genetic deficiency in TLRs and molecules implicated in the lipid metabolism, such as ApoE or LDL receptor. Furthermore, a more recent technique, such as the bone marrow transplantation (BMT), can be a useful and straightforward method to elucidate the role of stromal versus hematopoietic cells in the acceleration of the atheroma.
