Myelin oligodendrocyte glycoprotein (MOG), a member of the immunoglobulin (Ig) superfamily, is myelin protein expressed at outermost lamellae sheaths and oligodendrocytes (OGD) memb...

Human thymus cells synthesize immunoglobulin in short-term culture, the nascent immunoglobulin appearing in both cytoplasmic and membrane fractions. Surface immunoglobulin was demonstrated by lactoperoxidase radioiodination of the cells. The demonstration of intracellular and surface immunoglobulin required procedures that minimize proteolytic degradation. Noncovalently linked, monomeric mu cha...

BACKGROUND Hepatitis B vaccine and hepatitis B immunoglobulin are considered for newborn infants of HBsAg-positive mothers to prevent hepatitis B infection. OBJECTIVES To assess the beneficial and harmful effects of hepatitis B vaccines and hepatitis B immunoglobulin in newborn infants of HBsAg-positive mothers. SEARCH STRATEGY Trials were identified through The Cochrane Neonatal Group Cont...

Investigation of biosynthesis of J chain in plasmacytomas induced in NZB mice revealed that this protein was not only synthesized in the cells that produce polymer immunoglobulin A but also in those that produce immunoglobulin G monomer. It was also found that protein similar to J chain of BALB/c-mice was associated with polymer immunoglobulin A but not with immunoglobulin G of NZB mouse myelom...

Intravenous immunoglobulin infusion induces acute renal failure via a mechanism of osmotic nephrosis. Most reported cases are related to the use of sucrose-based intravenous immunoglobulin. Maltose-based intravenous immunoglobulin is thought to be a safer alternative and have a lower risk of renal toxicity than sucrose-based preparations. Maltase, but not sucrase, is present in the brush border...

Evidence shows that psychosocial factors are associated with immunoglobulin G response to medical vaccinations. As yet, there are no reports of whether the earlier immunoglobulin M response is similarly susceptible. This study examined the association between psychological stress, social support and the immunoglobulin M response to vaccination with pneumococcal capsular polysaccharides. Stressf...

The effect of immunoglobulins and complement (C) on phagocytosis and intracellular killing of Escherichia coli was studied in vitro. The incubation system consisted of monolayers of human polymorphonuclear leukocytes and C-resistant, [3H]thymidine-labeled E. coli C source was human serum deprived of immunoglobulins and properdin by immunoabsorption. In the absence of C, only immunoglobulin G-co...

Somatic hypermutation in B cells is initiated by activation-induced cytidine deaminase-catalyzed C→U deamination at immunoglobulin variable regions. Here we investigate the role of the germinal centre-associated nuclear protein (GANP) in enhancing the access of activation-induced cytidine deaminase (AID) to immunoglobulin variable regions. We show that the nuclear export factor GANP is involved...

Pregnant cows were successfully hyperimmunized with all four human rotavirus serotypes, resulting in a 100-fold increase in neutralizing milk antibody titers over those of controls. Milk antibodies were isolated batchwise from 1,000 kg of pooled milk for the first 10 lactation days, yielding 10 kg of freeze-dried milk immunoglobulin concentrate consisting of 50% bovine milk immunoglobulins. Mil...
