The SARS-CoV-2 virus elicits humoral immune responses with the production of IgG, IgM and IgA isotypes. Different isotypes may predominate at different times post-infection. IgM and IgA isotypes ...

Their studies showed that total antibody test, which detects levels of IgM, IgG, and IgA antibodies against SARS-CoV-2, has higher sensitivity and specificity than tests for IgM, IgG alone ...

We have recently shown that FCRLA is a resident endoplasmic reticulum protein that binds Ig in this organelle. In striking contrast to the conventional plasma membrane FcRs, FCRLA binds multiple ...

The research team measured IgM, IgG and IgA antibodies to five viral antigens (three of them on the Spike protein contained in the vaccine). Exposure to fine particulate matter (PM2.5), black ...

Typical acute hepatitis A virus (HAV) infection is accurately diagnosed by anti-HAV IgM detection. Molecular detection of HAV and anti-HAV IgG avidity testing are indicated to define protracted or ...

Further analysis revealed that felzartamab administration resulted in selective and durable reductions in IgA antibody levels ...

and IgA (23 mg/dL) were decreased. Protein C, S, and antithrombin III were within normal range. Anticardiolipin antibodies (IgG, IgM) were negative. Dilute Russell's viper venom time and this ...
