Yeah... I have one major gripe with this article. HIV particles hold RNA and not DNA. Reverse transcription of the RNA into double stranded DNA occurs within the host's cell and the resulting viral DNA is transported into the nucleus. Once inside the nucleus, the viral DNA is integrated with the host's DNA which leads to the hijacking of the cell.
Also, the process of reverse transcription can be quite inaccurate which is what causes the rapid mutations of the surface glycoproteins (though they did suggest that mutations affecting the capsid occurs less frequently).There's nothing to stop a mutation leading to a change in structure of the capsid proteins which, would therefore render anything targeting those particular proteins ineffective as protein-protein interactions are highly specific.
That being said, I'm sure this will open more avenues for potential drug targets so fingers crossed for some good news!
