It is a deadly disease that has so far evaded a accomplished cure . Successful discourse ofrabiesdepends on how cursorily medical help is given after exposure to the virus , and if it handle to reach the nervous system then it is almost invariably fatal . But the deadly virusmay withstand the keyto lick one of the trickiest problems in medicine .
The human body has evolved such an effective protection system , that for a farsighted time doctors have beentrying to visualise out a wayto break the descent - brain barrier in gild to deliver drug to the learning ability . It seems that move around to nature itself may well help solve the problem . By study how the rabies computer virus manages to taint brain tissue paper , researchersmay have encounter a wayto deliver neoplasm - killing drugs .
During its prospicient history of evolution , the rabies virus has found a room to in effect bypass the blood - brain roadblock , rather than breach it . When someone is infect with rabies , it is most often delivered to the muscle tissue through the bite of an infected animal , like a dog or a bat . The computer virus then travels through the tissue paper until it hits upon the central nervous system , using this to travel up and into the brain . research worker are now mimicking this process in ordination to find a new way to get drug to brain cancers .
In a unexampled subject area , put out inAdvanced Materials , researchers engineered Au nanoparticles into the physique of the rabies virus and coated them in some of the surface protein found on the computer virus , before injecting them into black eye that were breed to have brain tumors . They observe that within hours the particles had migrated through the uneasy system of the mouse and into the brain . By then fire up these particles with lasers that go past harmlessly through the hide , the researchers claimed that they were able to significantly cringe the brain tumor due to the heating plant emitted from the gold .
Whether or not this research could lead to an good intervention for brain tumor is , however , still to be take in . Some researchers question whether or not the gold nanoparticles only home in on the tumor cells , or if they are also found in other tissues of the body , meaning that any treatment with lasers could in fact have accidental side effects and kill other healthy body cells . If these inquiry can not be addressed , it will make it significantly more unmanageable to get approval for use of goods and services in world .
