Opportunistic infections, such as aspergillosis, are among the most serious complications suffered by immunocompromised patients. Aspergillus fumigatus and other pathogenic fungi synthesize a toxic epipolythiodioxopiperazine metabolite called gliotoxin. Gliotoxin exhibits profound immunosuppressive activity in vivo. It induces apoptosis in thymocytes,(More)
The transforming gene (src) of avian sarcoma virus (ASV) and adjacent regions of the viral genome have been isolated by molelcular cloning of viral DNA. Their nucleotide sequence encompasses the whole of src and the portion of the gene env that encodes gp 37, one of two glycoproteins found in the viral envelope. Src encodes a single, hydrophobic protein(More)
The genomes of numerous avian retroviruses contain at their 3' termini a conserved domain denoted "c". The precise boundaries and function of "c" have been enigmas. In an effort to resolve these issues, we determined the sequence of over 900 nucleotides at the 3' end of the genome of the Schmidt-Ruppin subgroup A strain of avian sarcoma virus (ASV). We(More)
