    Abstract As dendritic antigen-presenting cells in skin and mucous membranes, Langerhans cells (LC) are found in areas at risk of inoculation by the human immunodeficiency virus (HIV). LC have been reported as targets for HIV-1. The aim of the present study was to investigate whether LC can be experimentally infected by HIV provided by a cell-free infection system. A cell-free suspensions was prepared from viral particles provided by chronically infected cell lines (U937 or H9 cells) by low-speed centrifugation followed by 0.45-Μm filtration. LC-enriched epidermal cell (EC) suspensions with no CD3+ cells (assessed by flow cytometry and electron microscopy) and uninfected U937 cells (cell-free infection system control) were infected with two isolates (HTLVIII-B and RF). The infectiousness of the cell-free virus fluids was controlled on U937 cells where proviral DNA was amplified (gag, pol, and env gene sequences by the polymerase chain reaction, PCR) and release of virus particles into the supernatant was controlled either by measure of the reverse transcriptase (RT) activity or detection of viral RNA amplified by RT-PCR for the gag gene sequences). Proviral DNA (gag gene sequences) was found in LC-enriched epidermal cellular DNA from day 4 post-infection with isolate HTLVIII-B and from day 7 with isolate RF. Although the RT activity did not reach a significantly high level, viral RNA was found in the supernatant of LC-enriched EC cultures at the same time as proviral DNA was detected in LC. The findings indicate that the cell-free virus-infection model leads to a later-occurring infection and a lower HIV expression as compared with cell-to-cell transmission. This model allowed us to confirm the CD4-independent infection of isolated trypsin-treated LC and thus may be attractive for in vitro study of this type of infection.

    Abstract The Aspergillusniger and Trichodermareesei genes encoding the functional homologues of the small GTP-binding protein SAR1p, which is involved in the secretion pathway in Saccharomyces cerevisiae, have been cloned and characterised. The A. niger gene (sarA) contains five introns, whereas the T. reesei gene (sar1) has only four. In both cases the first intron is at the same position as the single S. cerevisiae SAR1 intron. The encoded proteins show 70–80% identity to the SAR1 protein. Complementation of S. cerevisiaesar1 and sec12 mutants by expression vectors carrying the A. nigersarA and T. reesei sar1 cDNA clones confirmed that the cloned genes are functional homologues of the S. cerevisiae SAR1 gene. Three mutant alleles of the A. nigersarA gene (D29G, E109K, D29G/E109K), generated by site-directed mutagenesis, revealed a thermosensitive dominant-negative phenotype in the presence of the wild-type sarA allele. This result contrasts with the situation in S. cerevisiae, where similar mutations have a thermosensitive phenotype. Taken together, our results indicate that the sarA gene is involved in an essential function in A. niger.
