British scientists have discovered a new way to fight the malaria epidemic, which is the deadliest global diseases.

The British newspaper The Independent that the discovery done by scientists from the Institute of the Wellcome Trust Sanger in Cambridge gives hope of ending this disease globally thanks to the discovery decisive element in the red blood cells of human and which seems to be a key element to complete the malaria parasites life cycle within the human body, which leads to identify the weak point of the disease.

The newspaper reported that work behind the disclosure, which was published in the newspaper / The Journal Nature / focus on the second phase of the life cycle of malaria in the human body after leaving the liver to invade red blood cells during what is known as phase / Aloksoma / as scientists were able to identify human protein called / Basigan / on the outer membranes of human red blood cells, which appears to be parasites need to open the cell membrane and the invasion.

The newspaper quoted Julian Renner, a doctor from the Institute / Sanger / saying he was discovered lock protease decisive on the surface of red blood cells of human that allows the introduction of mosquitoes for the key and then the disease adding that he could interaction between the malaria parasite and red blood cells that form the basis of making vaccine saves millions of people.

He explained Reiner that malaria parasites move between mosquitoes and humans, but the stage that cause the occurrence of symptoms is when invade red blood cells of human because they need to enter the cells to carry out the division and proliferation and doubled prepared and which is essential to the continuation of parasites alive, but it a potential target for attack.

The newspaper said the scientists were able to identify the main protein / future / red cell membrane and used antibodies have been designed for future adhesion protein replication for the parasite to prevent the parasite from the use of the key that opens the lock of red blood cells.

The newspaper said that scientists believe that this matter could mean the possibility of the vaccine industry prevents the development of these parasites inside the patient's body is nothing to prevent the occurrence of disease and transferred through mosquitoes.

Malaria is the biggest killer of children it causes the death of a million people annually, most of them children under five years of age in Africa.

The scientists spent decades in an attempt to devise vaccines that protect people from infection or can control the growth of parasites if entering the human body, but the complexity of the life cycle of the parasite foiled manufacture effective vaccines.
