          Abstract

          Objectives: Assuming an immune component in the pathogenesis of atherosclerosis, we have investigated a possible association between coronary artery disease (CAD) and the acid phosphatase locus 1 (ACP1) genetic polymorphism, which has previously been found to be associated with immune disorders. Methods: 226 subjects admitted to the hospital for CAD, 358 consecutive newborn infants, 279 adult subjects with type 2 diabetes without CAD and 137 adults without diabetes and without CAD from the Caucasian population of Rome were studied. The ACP1 genotype was determined by DNA analysis. Statistical analyses were performed using the SPSS package. Results: CAD females showed an excess of ACP1 *A/*C and *B/*C genotypes and a deficiency of ACP1 *B/*B genotype compared to controls, while CAD males did not show significant differences. Among diabetic women the proportion of *C allele carriers was much greater in those with CAD than in those without CAD. This difference was much less evident in nondiabetic women. Conclusion: ACP1 may be involved in susceptibility to CAD. Since ACP1 has been found to be associated with immunological diseases, our observation reinforces the notion of an immune component in the pathogenesis of atherosclerosis.

          Analysis of human Y-chromosome-specific reiterated DNA in chromosome variants.

          J Rary, Morgan H. Jones, Michael R. Miller … (1977)
          A number of individuals with aberrant Y chromosomes have been tested for the presence of Y-chromosome-specific reiterated DNA. These studies locate Y-chromosome-specific reiterated sequences on the long arm of the Y chromosome. Correlation with phenotype and other known Y chromosome markers establish that the Y-chromosome-specific reiterated DNA discussed here has no evident role in male determination.

            Atherosclerosis in patients with autoimmune disorders.

            Johan Frostegård (2005)
            Recent findings indicate that presence of activated immune competent cells and inflammation are typical of atherosclerosis, the main cause of cardiovascular disease (CVD). The risk of CVD is very high in a prototypic autoimmune disease, systemic lupus erythematosus (SLE), and is also raised in other autoimmune diseases such as rheumatoid arthritis. Autoimmunity-related CVD and atherosclerosis are important clinical problems. They may also shed light on interactions between immune reactions and atherosclerosis development and manifestations, not least in women, who have a much higher risk of autoimmune disease than men. In general, a combination of traditional and nontraditional risk factors, including dyslipidemia (and to a varying degree, hypertension, diabetes, and smoking), inflammation, antiphospholipid antibodies (aPLs), and lipid oxidation, contribute to CVD in autoimmune diseases. Premature atherosclerosis is likely to be a major underlying mechanism, although distinctive features, if any, of autoimmunity-related atherosclerosis compared with "normal" atherosclerosis are not clear. One interesting possibility is that factors such as inflammation, neoepitopes on endothelial cells, or aPLs make atherosclerotic lesions in autoimmune disease more prone to rupture than in "normal" atherosclerosis. Some cases of autoimmunity-related CVD may be more related to thrombosis than atherosclerosis. Whether premature atherosclerosis is a general feature of autoimmune diseases such as SLE or only affects a subgroup of patients whereas others do not have an increased risk remains to be demonstrated. Treatment of patients with autoimmune disease should also include CVD aspects and be focused on traditional risk factors as well as on disease-related factors. Hopefully novel therapeutic principles will be developed that target the causes of the inflammation present in atherosclerotic lesions.

              Implication of natural killer T cells in atherosclerosis development during a LPS-induced chronic inflammation.

              Daniel Scott, Mario Zakin, Delia Recalde … (2002)
              Atherosclerosis has many features of a chronic inflammatory disease. To evaluate the role of lipopolysaccharide (LPS), mimicking a systemic infection, we administered the endotoxin to apolipoprotein E (apoE)-deficient mice. LPS injections increase the atherosclerotic lesion size and the titer of plasma autoantibodies directed against oxidized low-density lipoprotein. We found that Th1 and Th2 T cells help the activation of B cells in the autoimmune response. The number of interleukin-4 producing natural killer T cells is highly increased in peripheral blood, liver, spleen and thymus cells, as well as in the atherosclerotic plaque of the LPS-treated mice. Finally, an important adventitial infiltrate of activated lymphocytes, sign of an advanced atherosclerosis, is observed only in the LPS-treated mice. Our results demonstrate that LPS administration aggravates atherosclerosis in apoE-deficient mice. LPS-injected apoE-deficient mice appear to be an excellent animal model to analyze the implementation of new therapeutic approaches in the treatment of atherosclerosis by manipulating immunological effectors.
