Decreased inflammatory cytokine production of antigen-specific CD4 T cells in NMDA receptor encephalitis.

Anti-N-methyl-D-aspartate-receptor (NMDAR) encephalitis is the most common autoimmune encephalitis with psychosis, amnesia, seizures and dyskinesias. The disease is mediated by pathogenic autoantibodies against the NR1 subunit that disrupt NMDAR function. Antibody infusion into mouse brains can recapitulate encephalitis symptoms, while active immunization resulted also in strong T cell infiltration into the hippocampus.

Human gestational N-methyl-d-aspartate receptor autoantibodies impair neonatal murine brain function.

Objective: Maternal autoantibodies are a risk factor for impaired brain development in offspring. Antibodies (ABs) against the NR1 (GluN1) subunit of the N-methyl-d-aspartate receptor (NMDAR) are among the most frequently diagnosed anti-neuronal surface ABs, yet little is known about effects on fetal development during pregnancy.

Methods: We established a murine model of in utero exposure to human recombinant NR1 and isotype-matched nonreactive control ABs.

[Efficiency and specificity of the KAT-test for rapid diagnosis of falciparum malaria].

A new rapid KAT Quick Malaria test for the diagnosis of falciparum malaria, which is based on the detection of a monoclonal antibody-antigen complex of malaria parasites, has been worked out by the KAT Medical CC in South Africa. The efficiency and specificity of the KAT test were compared with those of the microscopic method and with the ICT test for rapid diagnosis of P. falciparum and P.
