Assessing the impact of an antigen-specific antibody response on atherosclerosis development in mice.

Abstract

The antibody immune response plays a critical role in atherosclerosis. Here, we present a protocol for assessing the impact of an antigen-specific germinal center antibody response on atherosclerosis development, using a pro-atherogenic mouse model deficient for the production of germinal-center-derived antibodies. We describe steps for bone marrow transfer from donor mice into irradiated recipient mice. We then detail immunization of mouse chimeras with atheroprotective malondialdehyde low-density lipoprotein during high-fat diet feeding and atherosclerosis burden analysis. For complete details on the use and execution of this protocol, please refer to Martos-Folgado et al. (2022).1.
