Down modulation of human TLR3 function by a monoclonal antibody.

abstract：:Human K cells are able to lyse human lymphoblastoid B cells in the presence of specific anti-human immunoglobulin isotype antibodies. The human lymphoblastoid B-cell line DAUDI (surface mu- and kappa-chains positive) was lysed in the presence of anti-mu and anti-kappa antisera, or IgG fraction of these antisera, and B...
