Immunoglobulin GM and KM allotypes-genetic markers of gamma and kappa chains, respectively-are associated with immune responsiveness to several infectious pathogens and with survival in certain viral epidemics. We hypothesized that GM and KM allotypes affect the outcome of hepatitis C virus (HCV) infection. To test this hypothesis, we serologically(More)
There is increasing evidence for the involvement of herpes simplex virus type 1 and human cytomegalovirus in the cognitive impairment of patients with schizophrenia (SCZ). Both herpes simplex virus type 1 and human cytomegalovirus have evolved strategies for decreasing the efficacy of the host immune response and interfering with viral clearance.(More)
Studies in both humans and in animal models of specific disorders suggest that polymorphisms of multiple genes are involved in conferring either a predisposition to or protection from autoimmune diseases. Genes encoding polymorphic proteins that regulate immune responses or the rates and extent of metabolism of certain chemical structures have been the(More)
Serum samples were collected from 20 healthy White and 33 Black infants before and after immunisation with three doses of diphtheria-pertussis-tetanus vaccine and with one dose of Haemophilus influenzae type b polyribose phosphate vaccine and meningococcal group A and group C polysaccharide vaccines. Antibodies to these immunogens were measured and sera(More)
BACKGROUND Plasmodium falciparum malaria is a complex disease in which genetic and environmental factors influence susceptibility. IgG isotypes are in part genetically controlled, and GM/KM allotypes are believed to be involved in this control. METHODS In this study, 216 individuals from Daraweesh, an area of seasonal malaria transmission in Sudan, were(More)
IgG heavy-chain (Gm) allotypes were determined in 11 Caucasian patients with the syndrome of demyelinating polyneuropathy associated with monoclonal IgM autoantibodies with affinity for myelin-associated glycoprotein. The frequency of Gm phenotypes in the patient group was significantly different from that seen in a normal Caucasian population.
Guillain-Barré syndrome is associated with antecedent Campylobacter jejuni infection. Only a minority of the infected individuals, however, develops the disease, implying a role for genetic factors in conferring susceptibility. To determine the role of immunoglobulin KM genes (genetic markers of the constant region of kappa chains) in the etiology of this(More)
Monoclonal antibody (mAb) has fulfilled the promise of being the "Magic Bullet" in oncology with the clinical success of mAbs against CD20, Her-2/neu, epidermal growth factor receptor, vascular endothelial cell growth factor and others in a variety of cancers. Most manufacturers of mouse-human chimeric antibodies (and most immunologists) have treated the(More)
GM and KM allotypes-genetic markers of immunoglobulin (Ig) gamma and kappa chains, respectively-are associated with humoral immunity to several infection- and autoimmunity-related epitopes. We hypothesized that GM and KM allotypes contribute to the generation of autoantibodies to liver/kidney microsomal antigen 1 (LKM1) in hepatitis C virus (HCV)-infected(More)
