In this case report, we describe for the first time a patient with thrombotic thrombocytopaenic purpura (TTP) accompanying highly active systemic lupus erythematosus (SLE) that was associated with non-neutralizing antibodies against the plasma metalloprotease ADAMTS13. Those non-neutralizing antibodies could have been the cause of ADAMTS13 depletion and consecutive TTP. More extensive analyses ...
The production of protective neutralizing antibodies occurs quickly in some viral infections but very slowly in others. In a new study, surface glycoproteins (the targets of neutralization) of 2 different viruses were genetically switched. Analysis of the neutralizing antibody response to each of the 2 parent and recombinant viruses in infected mice revealed that the speed of neutralizing antib...
Neutralizing antiviral antibodies are typically detected on the basis of inhibition of viral function, such as propagation of a viral infection or inhibition of viral gene expression. Evidence is presented that anti-adenovirus neutralizing antibodies can be evaluated by analysis of cell-associated capsids or by analysis of intracellular trafficking of the capsids within 1 h after infection. Qua...
Serum samples from 689 hunter-killed white-tailed deer (Odocoileus virginianus) collected during the 2001 fall hunting season in New Jersey were tested for neutralizing antibodies to West Nile virus (WNV) and St. Louis encephalitis virus (SLEV) by plaque-reduction neutralization tests. WNV-neutralizing antibodies were detected in six (0.9%) of the samples, and SLEV-neutralizing antibodies were ...
Extending our previous analyses to the most recently described monoclonal broadly neutralizing antibodies (bNAbs), we confirmed a drift of HIV-1 clade B variants over 2 decades toward higher resistance to bNAbs targeting almost all the identified gp120-neutralizing epitopes. In contrast, the sensitivity to bNAbs targeting the gp41 membrane-proximal external region remained stable, suggesting a ...
Tick-borne encephalitis (TBE) virus infection elicits a life-long lasting protection. However, little is known about the neutralizing antibodies titres following natural infection. In this study, subjects with past TBE disease (n = 62) were analysed for the presence and titre of anti-TBE neutralizing antibodies, and compared with a vaccinated cohort (n = 101). Neutralizing antibody titres were ...
UNLABELLED Hypervariable region 1 (HVR1) (amino acids [aa] 384 to 410) on the E2 glycoprotein of hepatitis C virus contributes to persistent infection by evolving escape mutations that attenuate binding of inhibitory antibodies and by blocking access of broadly neutralizing antibodies to their epitopes. A third proposed mechanism of immune antagonism is that poorly neutralizing antibodies bindi...
BACKGROUND Rabies is a neglected zoonotic disease caused by viruses belonging to the genus lyssavirus. In endemic countries of Asia and Africa, where the majority of the estimated 60,000 human rabies deaths occur, it is mainly caused by the classical rabies virus (RABV) transmitted by dogs. Over the last decade new species within the genus lyssavirus have been identified. Meanwhile 15 (proposed...
Administration of adenovirus (Ad) vectors to immunologically naive experimental animals almost invariably results in the induction of systemic anti-Ad neutralizing antibodies. To determine if the human systemic humoral host responses to Ad vectors follow a similar pattern, we evaluated the systemic (serum) anti-Ad serotype 5 (Ad5) neutralizing antibodies in humans after administration of first ...
A clinical study of lyophilized intravenous human immunoglobulin containing high-titer cytomegalovirus-neutralizing antibody for the treatment cytomegalovirus viremia after allogeneic hematopoietic stem cell transplantation
