Is an Expression System for Producing Therapeutic Antibodies with Immunosuppressive Properties Found at Last? Comment to Letter by Dr. Quagliaroli

摘要

The prophylaxis of the hemolytic disease of the newborn — a mandatory procedure in obstetrics — requires significant amounts of plasma-derived polyclonal anti-D immunoglobulin. Despite numerous attempts, the proper technology for mass production of effective monoclonal anti-D is still not available. LFB Biotechnologies is currently performing clinical trials with recombinant anti-D antibody that has low fucose content and is expressed in the cells of rat myeloma YB2/0. It was shown that this drug is well tolerated, accelerates fast clearance of D+ red blood cells, and can inhibit anti-D immune response in Rhesus-negative volunteers.
