IRF5 Variants Are Risk Factors for Systemic Lupus Erythematosus in Two Mexican Populations.

Introduction: Interferon regulatory factor 5 ( IRF5 ) is one of the pivotal genes implicated in systemic lupus erythematosus (SLE) among diverse ethnic groups, including Europeans, Asians, Hispanics, and Africans. Notably, its significance appears particularly pronounced among Hispanic populations. Previous studies have identified several single-nucleotide variants within IRF5 , such as rs2004640G/T, rs2070197T/C, and rs10954213G/A, as associated with susceptibility to SLE among patients from Mexico City.

Association of the polymorphisms rs179008 (), rs2004640 (), rs1800795 () and rs2280788 () with systemic lupus erythematosus in women of Mayan ethnicity from Yucatan.

IFN-α is the main cytokine in SLE, and single nucleotide polymorphisms (SNP) in different genes could induce it. To determine the association of rs2004640 (), rs179008 (), rs1800795 () and rs2280788 () with SLE in Mexican women with Mayan ethnicity. DNA and RNA were isolated from the peripheral blood of 110 patients and 200 healthy control subjects.

Systemic Lupus Erythematosus (SLE) is an autoimmune disease in which genetic factors play a role in the susceptibility to develop it. Genes related to the synthesis of interferons such as and genetics factors such as single nucleotide polymorphisms (SNPs) or copies number variation (CNV) in the gene have been involved with the development of the disease. The genetic differences between the populations contribute to the complexity of LES.

Serological and molecular analysis of parvovirus B19 infection in Mayan women with systemic lupus erythematosus in Mexico.

Background: Systemic lupus erythematosus (SLE) is a systemic autoimmune disease that mainly affects women, characterized by the production of autoantibodies. Its causal agent is unknown, but the combination of environmental, hormonal and genetic factors may favor the development of the disease. Parvovirus B19 has been associated with the development of SLE, since it induces the production of anti-single stranded DNA antibodies.

Expression of TLR-7, MyD88, NF-kB, and INF-α in B Lymphocytes of Mayan Women with Systemic Lupus Erythematosus in Mexico.

Background: Systemic lupus erythematosus (SLE) is a chronic inflammatory autoimmune disease involving multiple organs. It is currently accepted that several genetic, environmental, and hormonal factors are contributing to its development. Innate immunity may have a great influence in autoimmunity through Toll-like receptors.

Copy Number Variation of TLR-7 Gene and its Association with the Development of Systemic Lupus Erythematosus in Female Patients from Yucatan Mexico.

Systemic lupus erythematosus (SLE) is a systemic autoimmune disease characterized by the production of autoantibodies against self-antigens, which occurs most often in women between 15 and 40 years of age. The innate immunity is involved in the pathogenesis of SLE through TLR- 7. Genetic factors such as copy number variation (CNV) of target genes may contribute to disease development, but this possible risk has not yet been studied in SLE patients from Yucatan, Mexico.
