BACKGROUND The Cytotoxic T lymphocyte antigen (CTLA-4) is one of the major susceptibility genes associated with autoimmune diseases. Susceptibility to rheumatoid arthritis (RA) is determined by both environmental and genetic factors. The genetic contribution approaches 50-60%. The association between RA with the +49A>G CTLA-4 polymorphism in the Mexican(More)
Macrophage migration inhibitory factor (MIF) is an upstream pro-inflammatory cytokine that is associated with the pathogenesis of autoimmune inflammatory diseases including rheumatoid arthritis (RA). Two polymorphisms in the upstream region exist in the MIF gene and are associated with RA susceptibility or severity in different populations. In this(More)
An association between thrombophilic genes and obstetric conditions with early pregnancy termination has been previously proposed. In the present study we attempted to evaluate the possible association between thrombophilic genetic polymorphisms and habitual abortion (HA). Samples from two groups of volunteers were analyzed. The experimental group (n>100)(More)
Tumor necrosis factor-α (TNF-α) plays a central role in inflammation, and it has been directly implicated in the pathogenesis of rheumatoid arthritis (RA). TNF-α activity is mediated through TNFRI and TNFRII cell surface receptors, which act as physiological attenuators of TNF-α activity. We recruited 190 RA patients and 190 healthy subjects (HS) in order(More)
BACKGROUND Leprosy is a debilitating infectious disease of human skin and nerves. Genetics factors of the host play an important role in the disease susceptibility. Toll-interacting protein (TOLLIP) is an inhibitory adaptor protein within the toll-like receptor (TLR) pathway, which recognizes structurally conserved molecular patterns of microbial pathogens,(More)
Inflammation is a key event that is closely associated with the pathophysiology of frailty. The relationship of genetic polymorphisms into inflammatory cytokines with frailty remains poorly understood. The aim of this study was to investigate the association between VNTR polymorphisms of the IL-4 and IL-1RN genes with the risk of frailty. We included a(More)
BACKGROUND Acute coronary syndrome (ACS) has an important impact in public health with high morbidity and mortality. Prothrombotic and proinflammatory states are involved in the pathogenesis of the disease. Plasminogen activator inhibitor-1 (PAI-1) is the major inhibitor of the fibrinolysis and also is part of immune response. The -844 G>A gene polymorphism(More)
Macrophage migration inhibitory factor (MIF) is an upstream immunoregulatory cytokine associated with the pathogenesis of autoimmune inflammatory diseases. There is evidence that MIF functions in a positive feedback loop with TNF-α that could perpetuate the inflammatory process in systemic lupus erythematosus (SLE). In this case-control study we(More)
The macrophage migration inhibitory factor (MIF) is related to the progression of atherosclerosis, which, in turn, is a key factor in the development of acute coronary syndrome (ACS). MIF has a CATT short tandem repeat (STR) at position -794 that might be involved in its expression rate. The aim of this study was to investigate the association between the(More)
