FGFR4 and malaria: Having identified the interaction between human FGFR4 and P. falciparum Pf34, an investigation was undertaken to determine whether this interaction is conserved across species by testing murine FGFR4 for interaction with the Pf34 orthologs found in the rodent malaria parasites P. yoelii and P. berghei. No evidence of interaction was observed for either of these protein pairs, despite expression of all proteins at levels in the range expected to give optimal AVEXIS sensitivity (Additional file 1: Fig. S3A).
