Artemether resistance in vitro is linked to mutations in PfATP6 that also interact with mutations in PfMDR1 in travellers returning with Plasmodium falciparum infections.
BACKGROUND: Monitoring resistance phenotypes for Plasmodium falciparum, using in vitro growth assays, and relating findings to parasite genotype has proved particularly challenging for the study of resistance to artemisinins.
METHODS: Plasmodium falciparum isolates cultured from 28 returning travellers diagnosed with malaria were assessed for sensitivity to artemisinin, artemether, dihydroartemisinin and artesunate and findings related to mutations in pfatp6 and pfmdr1.
RESULTS: Resistance to artemether in vitro was significantly associated with a pfatp6 haplotype encoding two amino acid substitutions (pfatp6 A623E and S769N; (mean IC50 (95% CI) values of 8.2 (5.7 - 10.7) for A623/S769 versus 623E/769 N 13.5 (9.8 - 17.3) nM with a mean increase of 65%; p = 0.012). Increased copy number of pfmdr1 was not itself associated with increased IC50 values for artemether, but when interactions between the pfatp6 haplotype and increased copy number of pfmdr1 were examined together, a highly significant association was noted with IC50 values for artemether (mean IC50 (95% CI) values of 8.7 (5.9 - 11.6) versus 16.3 (10.7 - 21.8) nM with a mean increase of 87%; p = 0.0068). Previously described SNPs in pfmdr1 are also associated with differences in sensitivity to some artemisinins.
CONCLUSIONS: These findings were further explored in molecular modelling experiments that suggest mutations in pfatp6 are unlikely to affect differential binding of artemisinins at their proposed site, whereas there may be differences in such binding associated with mutations in pfmdr1. Implications for a hypothesis that artemisinin resistance may be exacerbated by interactions between PfATP6 and PfMDR1 and for epidemiological studies to monitor emerging resistance are discussed
Rhopalophthalmus macropsis Pillai 1964
Rhopalophthalmus macropsis Pillai, 1964 Type locality. Arabia Sea (Pillai 1964). Record from Thailand. South-eastern Andaman Sea, next to Phuket Island (Fukuoka & Murano 2002). Habitat and depth. Marine, depth: 40 m (Fukuoka & Murano 2002). Distribution. This species is known from Arabian Sea (Pillai 1964), Japan (Ii 1964), South China Sea (Ii 1964; Wang & Liu 1994), Strait of Malacca (Pillai 1973), East China Sea (Wang & Liu 1997), and Andaman Sea (Fukuoka & Murano 2002). Remarks. Among the species of the genus Rhopalophthalmus, this species can be easily distinguished by the telson being moderate in length, posterior end including spinose apical setae falling far short of end of uropodal exopod; rudimentary endopod of male eighth thoracopod elongated, extending beyond basal plate of exopod (Hanamura et al. 2011).Published as part of Yolanda, Rofiza, Ambarwati, Reni, Rahayu, Dwi Anggorowati, Budijastuti, Widowati, Fitrihidajati, Herlina, Kuntjoro, Sunu, Rachmadiarti, Fida & Purnomo, Tarzan, 2023, An annotated checklist of the species of Lopogastrida and Mysida (Crustacea Peracarida) from Thailand and its adjacent waters, pp. 201-232 in Zootaxa 5244 (3) on page 219, DOI: 10.11646/zootaxa.5244.3.1, http://zenodo.org/record/765626
