CD40LG and atherosclerosis: Less invasive studies have been carried out with people, and it has been shown that human IgM anti-oxLDL is inversely correlated with cardiovascular and carotid disease (12, 38, 39, 52–54), whereas IgG has been found to be positively correlated with atherosclerosis (12, 52, 55–60) or not correlated at all with vessel pathology (40, 61–64).
