CD73[1]

Mupadolimab induces the increased expression of markers associated with B cell maturation and antigen presentation, morphologic transformation to plasmablasts, and increased secretion of IgM and IgG[1].

Mupadolimab (10 mg/kg; i.p.; daily for 15 days) stimulates antigen specific humoral immunity in SARS-CoV-2 infected NSG-SGM3 mice[1]. Animal Model: NSG-SGM3 mice, immunized with an emulsion of 50 μg full length spike protein from SARS-CoV-2 and Freund’s Incomplete Adjuvant subcutaneously on both the left and right flank (25 μg/side)[1] Dosage: 10 mg/kg Administration: Intraperitoneal injection, daily for 15 days Result: Mice treated with the drug made antibodies to the immunizing TS protein; but not to the control nucleocapsid SARS-CoV-2 viral protein.
