SLC44A4 and infection: We also observed the same melanization phenotype in the A. gambiae Keele CTL4- and CTLMA2-silenced mosquitoes infected with the P. berghei ANKA 2.34 strain, which also achieves a high infection intensity; our findings corroborate previous observations using other mosquito and parasite strains (12, 39, 40) and thus confirm the conserved functions of these genes in various A. gambiae strains with regard to P. berghei infection.
