Bitterroot Bio Inc. presented data on an anti-CD47 hybrid protein, BRB-002, tested in a murine model of atherosclerosis. BRB-002 was tested at 2.5 or 10 mg/kg i.p. 3x/week after a high-fat diet. Firstly, BRB-002 was seen to bind CD47 with high affinity in several cell lines, but not in Jurkat CD47-knockout cells.
