title: Detection of HIV-1 DNA in pediatric AIDS brain tissue by two-step ISPCR.
abstract: In order to detect latent infection in neurons or other cell types in formalin-fixed brain tissue, we performed polymerase chain reaction amplification with incorporation of digoxigenin-conjugated deoxynucleotides, followed by in situ hybridization with biotinylated probes. The use of this two-step technique in brain tissue from a child with severe HIV-1 encephalitis revealed signal in both nuclear and perinuclear regions of cells identified as monocytes and astrocytes, and also in perineuronal satellite cells of glial morphology, but HIV-1 infection of neurons was not detected.
