In insects, the homologue of the Down syndrome cell adhesion molecule (Dscam) is a unique case of a single-locus gene whose expression has extensive somatic diversification in both the nervous and immune systems. How this situation evolved is best understood through comparative studies. We describe structural, expression, and evolutionary aspects of a Dscam(More)
Putative U6snRNA polymerase III (PolIII) promoters were cloned from the Anopheles gambiae and Aedes aegypti genomes. The PolIII promoters were tested for their ability to express short-hairpin RNA (shRNA) targeted to firefly luciferase and to mediate RNA interference (RNAi) knockdown of a co-transfected luciferase reporter gene vector in AG-55 Anopheles(More)
In this report the first description of MHC-DQB homologues in prosimians, the lemurs (Lemur fulvus sanfordi) and galagos (Galago garnetti and G. senegalensis moholi), is presented. In these species the class II alleles are similar to their human counterparts, in that the number and position of substitutions are analogous to the substitutions among various(More)
The CCR5 co-receptor is necessary for cellular entry by R5 tropic viral strains involved in primary HIV infection, but is dispensable for normal human physiology. Owing to its crucial role in HIV-1 infection, the CCR5 co-receptor has been the subject of many therapeutic approaches, including gene therapy. siRNA targeting was shown to be effective in(More)
The second exon of primate MHC-DRB genes encodes discrete areas of allelic hypervariability (HVR), which are used as the basis for lineage assignments to determine genetic and evolutionary relationships. Comparisons of these regions have led to the "trans-species hypothesis", which proposes that certain MHC alleles from one species are more closely related(More)
Amphotericin B is recommended for the treatment of systemic infection caused by Sporothrix schenckii. However, this agent is toxic, its use is frequently followed by relapse, and some isolates of S. schenckii are resistant. Recent studies suggest that newer azole compounds, such as itraconazole, are effective in cutaneous and lymphocutaneous sporotrichosis,(More)
The MHC DQ region in nonhuman primates, as in humans, consists of alpha and beta chains that are polymorphic with strong linkage disequilibrium between certain DQA-DQB alleles. Not only are contemporary HLA class II allelic variants present in evolutionarily distant species, but we demonstrate that linkages between loci also bear ancient roots. In unrelated(More)
