Washington April 18: A team of researchers including Indian-American scientist Souvik Bhattacharjee has identified a gene responsible for making malaria parasites resistant to artemisinins a key group of anti-malarial drug. The gene is a dominant marker used to track the parasite's resistance and causes artemisinin resistance. Mutation in the gene increases the kinase or enzyme levels which in turn increases the levels of a particular lipid called PI3P. The higher the level of this lipid present in the parasite the greater is the level of artemisinin resistance. Artemisinin combination therapies (ACTs) are the standard treatment worldwide for P. falciparum malaria.
