Formyl peptide receptor 1 (FPR1)

Mouse studies suggest stimulating neutrophil-expressed FPR1 could help treat toxoplasmosis and other chronic gastrointestinal infections. In a mouse model of Toxoplasma gondii-related gastrointestinal infection, deletion of Fpr1 decreased neutrophil recruitment and bacterial encapsulation by neutrophils and increased mortality compared with no deletion. Next steps could include exploring the therapeutic potential of N-formyl peptide-mediated stimulation of FPR1 in models of chronic gastrointestinal infection such as inflammatory bowel disease (IBD).
