Journal ArticleDOI
Design of copper DNA intercalators with leishmanicidal activity
Maribel Navarro,Efrén J. Cisneros-Fajardo,Anibal Sierralta,Mercedes Fernández-Mestre,Pedro Silva,Dwight Arrieche,Edgar Marchán,Edgar Marchán +7 more
TL;DR: Preliminary ultrastructural studies with the most active complex at 1 h revealed parasite swelling and binucleated cells, which suggests that the leishmanicidal activity of the copper complexes could be associated with their interaction with the parasitic DNA.
Journal ArticleDOI
TNF‐α‐308A allele, a possible severity risk factor of hemorrhagic manifestation in dengue fever patients
TL;DR: This work describes single-nucleotide polymorphism of tumor necrosis factor (TNF)-alpha, interferon-gamma, interleukin (IL)-6, transforming growth factor-beta1, and IL-10 in patients with dengue virus infections and analyzes their relation with clinical manifestations of the disease.
Journal ArticleDOI
Influence of CTLA-4 gene polymorphism in autoimmune and infectious diseases.
Mercedes Fernández-Mestre,Karen Sánchez,O. Balbas,Ketevan Gendzekhzadze,Ketevan Gendzekhzadze,Violeta Ogando,Mayra Cabrera,Zulay Layrisse +7 more
TL;DR: The results indicate that the polymorphism of CTLA-4 is an important genetic factor associated with risk or protection for the development of diffuse cutaneous leishmaniasis and has influence in the pathogenesis of autoimmune diseases.
Journal ArticleDOI
Synthesis, characterization, DNA binding study and biological activity against Leishmania mexicana of [Cu(dppz)2]BF4
Maribel Navarro,Efréen J. Cisneros-Fajardo,Mercedes Fernández-Mestre,Dwight Arrieche,Edgar Marchán +4 more
TL;DR: Preliminary studies of the ultrastructure of L. mexicana treated with a sublethal dose of the title complex showed an induction of cytoplasm disorganization, vacuolization and binucleated cells, suggesting that the leishmanicidal activity of theTitle complex could be associated with its interaction with the parasitic DNA.
Journal ArticleDOI
Genetic contribution of major histocompatibility complex class II region to type 1 autoimmune hepatitis susceptibility in Venezuela
María del Pilar Fortes,Irma Machado,Gisselle Gil,Mercedes Fernández-Mestre,Lucy Dagher,Roberto V. León,Nicolas E. Bianco,Paolo Tassinari +7 more
TL;DR: Type 1 AIH is a progressive liver disease characterized by the presence of circulating autoantibodies, hypergammaglobulinaemia and a favourable response to immunosuppressive treatment and disease susceptibility is partially determined by genes linked to the class II region of the major histocompatibility complex.
