Thematic review series: the immune system and atherogenesis. Immune function in atherogenesis

In this overview to a new thematic series on the immune system and atherogenesis, I provide a very brief summary of current conceptions of atherogenesis, of the innate and adaptive immune systems, and of the participation of the latter in atherogenesis, with particular emphasis on studies of the involvement of the immune system in atherosclerosis reported in the last 2 years. This is followed by a short outline of the eight reviews that will make up this thematic series. The overview is concluded with some caveats that should be considered in the analysis of atherosclerosis in experimental animals.
