In a recent study, scientists at Johns Hopkins University have narrowed down a list of 25 human proteins that HIV viruses target the most. The scientists started by studying the HIV-1virus, which is the most infectious and most common type of HIV. They knew that the virus clings to proteins and membrane as it emerges from an infected human cell in order to disguise itself from the human immune system, but inquired as to whether it was a random process or not. They then searched for types of proteins that they targeted the most, using the HIV-1.

They virus tends to target the CD4+ T cells and microphages which both migrate to sites of inflammation. This makes sense because HIV targets the immune system and  the virus can wait to attack while disguised by these cells. They originally identified 279 proteins that this virus in particular targeted when isolating the HIV-1 with CD4+ T cells, but when they crossed the data from two different cell types, they found that only 25 proteins were shared by viruses from both cell types!

This is an extremely interesting and groundbreaking discovery because of the possibilities behind this discovery. If we can figure out the types of proteins these HIV viruses are hiding behind, we could target and destroy them which could possibly lead to the abolition of HIV.
