Figure 1 Enhancement of HIV Infection by SEVI Prostatic acid phosphatase (PAP), an abundant protein in semen, is cleaved into the PAP248-286 peptide, which then aggregates to form amyloid fibrils termed semen-derived enhancer of viral infection (SEVI) (Münch et al., 2007). The fibrils capture HIV virions and direct them to target cells to which they fuse. Under conditions of a limiting viral inoculum, SEVI enhances infectivity of HIV virions by more than 100,000-fold Cell 2007 131, 1044-1046DOI: (10.1016/j.cell.2007.11.030) Copyright © 2007 Elsevier Inc.
