CD79A and viral encephalitis: Recent studies of ovarian teratomas from patients with anti–N-methyl-D-aspartate receptor (anti-NMDAR) encephalitis have shown that teratomas from NMDAR encephalitis are much more likely to contain predominantly glial elements suggestive of neuroglial tumors than those without encephalitis and may also have extensive infiltrates of T and B cells as well as IgG and IgA deposits in close contact with the neuroglial components of the teratomas14.
