New Protein Could Be Breakthrough in HIV Prevention
11 years ago
The race to eradicate HIV and improve the vaccine has led to an exciting new development. Researchers within the last few weeks have published new findings regarding a protein and sugar molecule that has the potential to not only neutralize HIV, but that can connect to various strains of the virus as well.
The protein that was created mimics the outer layer of the HIV. The part of the layer that can bind to antibodies is the area researchers were targeting. This key part of the cell is where neutralizing the virus takes place. One of the factors that make the creation of this protein so important is that it may help scientists answer some of the most complex issues facing the prevention of HIV. For one thing, an antibody that can target multiple strains of the virus is hard to come by. Another problem is the response of the immune system: At times it is beneficial, but other responses can be negative and unwanted. Researchers are hoping that, with this protein, the immune system will be free to respond in a positive, beneficial way. The protein with the sugar molecule is better able to bond to the outer coat of the virus. It is hoped that broad-spectrum antibodies will be allowed to form. If this happens, the antibodies that can do the most neutralizing will have a better chance to complete their task.
Another benefit to the proteins is the potential to trigger a response from the white blood cells that produce antibodies. Should the antibodies produced by these B cells do what researchers are hoping, results could be disastrous for the virus. This aspect is what scientists are focusing on to develop an effective vaccine. Much more information is needed, as well as testing on animal subjects. This does not, however, negate the importance that this finding will have on the future of the battle against HIV.
Importance of Early HIV Infection Detection

The war on HIV rages on. While medical advancements in treatment and therapy have shown progress, there are still areas that need attention. Recent studies still show that a high percentage of Europeans infected with HIV are receiving or entering into treatment at later stages. Countries throughout the continent are still showing late detection for those with HIV. Worrisome findings reveal that many who were finally tested for the virus developed AIDS within only a few months after diagnosis. This emphasizes the need for earlier detection.
Overall, the numbers show a decrease in late detection for Europe. The increase seems to be in certain target groups and in certain regions. For example, the number of drug users (injection drugs) who presented with late detection of HIV has steadily increased. Certain countries are particularly vulnerable to this rise in numbers at present. The threat goes beyond that to the infirmed. Communities are now at risk as spreading the virus can happen unbeknownst to either party involved. An increased focus at early testing and prompt entry into treatment are highly recommended. Education and readily available programs should be implemented.
One reason these findings should motivate action is that those who remain untreated or even undiagnosed find themselves worse off health-wise in the long run. Along with this, the likelihood of spreading the disease increases greatly. While medication and therapies cannot yet cure HIV, they do have benefits. For one thing, antiretrovirals help reduce the amount of the virus carried, thus aiding in the prevention of spreading the infection. Patients receiving early treatments tend to be healthier and fare better. These positive results give birth to hope.
The battle goes on against HIV/AIDS. Education targeting the groups most at risk is imperative. Making sure proper steps are taken in a timely fashion to ensure immediate treatment after diagnosis is another area needing some attention. Through education and awareness, the population can protect against, treat and heal from the effects of HIV.
