HIV Phylogenetic analysis: a literature review The authors performed a literature review to analyse HIV phylogenetic analyses methods as a forensic tool. Because HIV is a fast-evolving virus, HIV genomic sequences of several individuals can be used to investigate whether they belong to a transmission network. Since the infamous ‘Florida dentist case’ in the beginning […]

OBJECTIVE:
Memory B-cell loss has long been recognized as an important contributor to HIV immunodeficiency. HIV-2 infection, which is characterized by a slow rate of progression to AIDS and reduced to undetectable viremia, provides a unique model to investigate B-cell disturbances.
