Deskripsi
Here, the authors apply positron emission tomography (PET) imaging to visualize HIV tissue-wide burden in infected individuals using a radiolabeled broadly neutralizing antibody, 89Zr-VRC01, and show that PET tracer lymph node uptake positively correlates with HIV protein levels measured directly from cells obtained from these tissues. This strategy may allow non-invasive characterization of residual HIV infection in the setting of therapeutic interventions.
