The FPR family members including FPR, formyl peptide receptor like-1 and -2 (FPRL1, FPRL2), are differently expressed in phagocytes with neutrophils expressing FPR and FPRL1 and monocytes/macrophages expressing all three. FPRL1 may constitute an additional molecular target for the development of therapeutic agents for Alzheimer's disease (AD). GenScript has created a cell line that expresses FPRL1 in the CHO-K1 expressing Ga15.
