HIV vaccine can be introduced in recent years: solving infection problems from the source
More than 30 years ago, scientists have determined that HIV is the cause of AIDS, but until now we have not designed an effective vaccine. Although doctors can now use a range of drugs to control the condition of infected people (up to several decades), it is the best weapon to develop a vaccine that can prevent viral infection. And in developing countries, the cost of drugs and other factors can make many people unable to get effective treatment. In the absence of effective treatment, patients will slowly develop serious immunodeficiency problems (acquired immunodeficiency syndrome, AIDS), and in a few years, they will face the threat of death.
Vaccine development is slow because it is not an attempt or a lack of necessary financial support. The problem is that unlike other viruses that scientists have studied, HIV is so different. Any effective antiviral vaccine must activate the immune system to attack and destroy the virus before it invades the cells and spreads throughout the body. But HIV has evolved a defensive weapon against the body's immune system. It is like a devil, killing or damaging key immune cells, and these cells should have mobilized the body to launch a defensive counterattack. It is also a unique pretender, and the work of a large number of researchers on vaccine development has disappeared. No vaccine can quickly identify and prevent HIV mutation and prevent further infection. After nearly 20 years of hard work, our joint research team has finally synthesized an artificial protein that helps vaccine manufacturers overcome the difficulties they faced in the past. Our experiments have shown that this molecule can evoke a strong immune response in animals against HIV. However, in order to be used as a human vaccine, further debugging is needed to more effectively and better deal with multiple virus strains.
There is still a long way to go for follow-up work. Our labs and other teams are already pushing the relevant research quickly. Everyone is confident that we are finally on the right path.
Brand new structure
The target of our simulation is the envelope protein of HIV (Env). Now, we can synthesize proteins that are closer to this substance than before. The envelope protein forms spikes on the surface of HIV, allowing the virus to enter immune cells, such as CD4+ T lymphocytes. Normally, these T cells communicate with other parts of the immune system through their outer membrane proteins, including CD4 and CCR5 proteins, which are like signal towers at high altitudes. When HIV attempts to enter immune cells, it binds to CD4 or CCR5 proteins. The envelope protein also fuses the outer membrane of the virus with the outer membrane of the immune cell by distorting and reconstructing its own structure. At the same time as the membrane fuses, the virus releases its own genes into the cells, producing hundreds of millions of copies of the virus. The assembled virus will escape the cells, spread to the surrounding cells, and repeat the infection process.
Researchers have always dreamed that HIV infection can be prevented as long as it can break the envelope protein. Among them, the most reasonable method is to "church" the human immune system to produce antibody molecules that specifically recognize and attach to the envelope protein of HIV. In theory, these antibodies should produce two effects. First, they should form a barrier that prevents HIV from attaching to CD4 and CCR5, thereby preventing the virus from entering CD4+ T cells. Second, ensuring that other parts of the immune system respond quickly, destroying the virus and removing debris. A similar strategy has been successful in other viral vaccines, such as the hepatitis B virus vaccine: in the laboratory, researchers use genetic engineering methods to obtain viral surface proteins, which are then injected into the human body, and the proteins themselves do not cause disease ( Because other parts of the virus are missing, they can induce the immune system to produce antibodies in the body. When a virus invades, it can quickly eliminate the virus by recognizing similar surface proteins.
Unfortunately, when using standard steps to develop HIV vaccines, scientists are always frustrated because its envelope protein is "blackmailed" and quickly decomposes once it is separated from the intact virus. Envelope protein fragments include the gp120 subunit, which is responsible for binding to the CD4 protein, and the gp41 subunit, which is responsible for anchoring the envelope protein to the surface of the virus, followed by promotion of fusion of the virus and immune cell membranes.
SARMs Capsules is a new performance-enhancing compound that is shaking up the fitness industry. They have the ability to promote muscle growth, fat loss, and even cardiovascular endurance. To maintain legitimacy, these new compounds sold for "research purposes" are emerging as promising alternatives to anabolic Steroids. A lot of people are there to promote a huge change in the body structure of SARM.
As we age, our endurance, strength, and skeletal muscle mass decline due to the gradual loss of type 2 muscle fibers. This severely limits our individual athletic performance. In this part of the androgen deficient population, the use of SARM, skeletal muscle mass, muscle strength will be significantly improved..
