Only if you overlook the claim that "Langerin is a natural barrier to HIV-1 transmission by Langerhans cells."
No, not really. Cells can express a lot of different proteins that are innately antiviral, but that doesn't mean that the cell still can't be infected. Infection of Langerhans and other classes of dendritic cells by HIV is a well established fact. Not to mention that on immune activation Langerhans cells become mature dendritic cells and stop expressing Langerin.
