Several studies suggest that the histocompatibility complex (HLA) class I region harbours genes modulating multiple sclerosis (MS) susceptibility independently from the effect of class II alleles. A candidate gene in this region is MOG, encoding the myelin oligodendrocyte glycoprotein. A significant association with the missense variation V142L (rs2857766)(More)
Perforin is involved in cell-mediated cytotoxicity and mutations of its gene (PRF1) cause familial hemophagocytic lymphohistiocytosis (FLH2). PRF1 sequencing in 190 patients with multiple sclerosis and 268 controls detected two FLH2-associated variations (A91V, N252S) in both groups and six novel mutations (C999T, G1065A, G1428A, A1620G, G719A, C1069T) in(More)
Inherited defects decreasing function of the Fas death receptor cause autoimmune lymphoproliferative syndrome (ALPS) and its variant Dianzani autoimmune lymphoproliferative disease (DALD). Since a deleterious mutation of the SH2D1A gene protects MRLlpr/lpr mice from ALPS development, we investigated the role of SH2D1A, located in the X chromosome, in 51(More)
Riachuelo is a heavy contaminated course of water, partially surrounding Buenos Aires city. The presence of bacteria resistant to antibiotics and heavy metals was studied. Among the isolated Gram positive colonies, 65, 59 and 48% were resistant to 60 micrograms/ml of Pb++, Zn++ and Cd++, respectively, and 20% grew in the presence of 50 micrograms/6ml(More)
