BT-R3 mediates killing of the malaria vector Anopheles gambiae by Bacillus thuringiensis
Date:8/23/2013

nior author of the paper, said "this kind of strategy will facilitate protein design for creation of new customized Cry proteins and peptide mimics that might be more effective than the natural toxins themselves against Anopheles gambiae and other mosquitoes, and, hopefully, less able to bring about insect host resistance."

New approaches are needed in the area of malaria control because no effective vaccine currently exists and no available anti-malarial medications have been designed or discovered that impede parasite resistance with long-term use. A few drugs have been able to provide relief to patients but a preventive anti-malarial vaccine is yet to be developed. Certainly, genetic modification of wild mosquito vector populations to reduce vectorial capacity is fraught with unknown and hidden trials and tribulations.

Dr. Steve Goodman, Editor-in-Chief of Experimental Biology and Medicine said "Lee Bulla and his colleagues have combined genomics, proteomics and in silico analysis to establish the role of the cadherin receptor BT-R3 in the killing action of Cry4B mosquito toxin. Understanding of this Cry4B-BT-R3 complex will allow the design of custom proteins and peptides to help control the spread of malaria by mosquitoes".
