A molecule that suppresses this pathogen in vitro was originally backronymed from the name of an alien in an Argentine movie. SDF-1 serves as an endogenous suppressor of syncytia-inducing strains of this pathogen. The Trofile assay differentiates between different types of this virus, which can identify if (*) maraviroc is an appropriate treatment. This virus’ Vpu protein (10[1])downregulates cellular tetherin. A 32-base-pair deletion mutation confers resistance to the m-tropic strains of this virus by denying its Gp120 protein access to the CCR5 co-receptor. Antiretroviral drugs like AZT aim to make this (10[1])virus “undetectable.” (10[1])Helper T cells are infected by, (10[1])for 10 points, what retrovirus that can cause AIDS? ■END■
