Genetic control of immune response in carriers of ancestral haplotype 8.1: the study of chemotaxis.
In all caucasian populations the association of an impressive number of autoimmune diseases with genes from the HLA-B8, DR3 hap- lotype that is part of the ancestral haplotype (AH) 8.1 HLA-A1, Cw7, B8, TNFAB∗a2b3, TNFN∗S, C2∗C, Bf∗s, C4A∗Q0, C4B∗1, DRB1∗0301, DRB3∗0101, DQA1∗0501, DQB1∗0201 has been reported by different research groups. This haplotype, which is more common in northern Europe, is also associated with a number of immune system dysfunctions in healthy subjects. Analyzing the data according to gender, some dysfunc- tions are observed in women but not in men, in agreement with the role of X-linked genes and/or estrogens in the development and progression of autoimmune diseases.…
Role of proinflammatory alleles in longevity and atherosclerosis: results of studies performed on -1562C/T MMP-9 in centenarians and myocardial infarction patients from Sicily.
Centenarians are characterized by marked delay or escape from age-associated diseases that cause mortality at earlier ages. Jointly, atherosclerosis and its complications, such as myocardial infarction (AMI), significantly contribute to mortality in the elderly. Inflammation is a key component of atherosclerosis and inflammatory genes are good candidates for the risk of the development of atherosclerosis. Genetic traits contribute to the risk of AMI and allelic variations in inflammatory genes should boost the risk of disease. If proinflammatory genotypes significantly contribute to the risk of AMI, alleles associated with disease susceptibility should not be included in the genetic backgro…
