SALO, a novel classical pathway complement inhibitor from saliva of the sand fly Lutzomyia longipalpis
Blood-feeding insects inject potent salivary components including complement inhibitors into their host's skin to acquire a blood meal. Sand fly saliva was shown to inhibit the classical pathway of complement; however, the molecular identity of the inhibitor remains unknown. Here, we identified SALO as the classical pathway complement inhibitor. SALO, an 11 kDa protein, has no homology to prote...
متن کاملStructure of SALO, a leishmaniasis vaccine candidate from the sand fly Lutzomyia longipalpis
BACKGROUND Immunity to the sand fly salivary protein SALO (Salivary Anticomplement of Lutzomyia longipalpis) protected hamsters against Leishmania infantum and L. braziliensis infection and, more recently, a vaccine combination of a genetically modified Leishmania with SALO conferred strong protection against L. donovani infection. Because of the importance of SALO as a potential component of a...
متن کاملToward an understanding of the biochemical and pharmacological complexity of the saliva of a hematophagous sand fly Lutzomyia longipalpis.
The saliva of blood-sucking arthropods contains powerful pharmacologically active substances and may be a vaccine target against some vector-borne diseases. Subtractive cloning combined with biochemical approaches was used to discover activities in the salivary glands of the hematophagous fly Lutzomyia longipalpis. Sequences of nine full-length cDNA clones were obtained, five of which are possi...
متن کاملPhylogeography of the neotropical sand fly Lutzomyia longipalpis inferred from mitochondrial DNA sequences.
Sand flies in the Lutzomyia longipalpis species complex include the primary vector of Leishmania chagasi, the etiologic agent of visceral leishmaniasis in the Neotropics. Twelve L. longipalpis populations from South and Central America were compared using the cytochrome c oxidase I (COI) gene from the mitochondrial genome. The haplotype profiles for each population revealed that the majority of...
متن کاملIsolation of maxadilan, a potent vasodilatory peptide from the salivary glands of the sand fly Lutzomyia longipalpis.
Blood feeding by the sand fly Lutzomyia longipalpis is aided by the presence of a vasodilator in its salivary glands. This novel vasodilator has been isolated by reversed-phase high-performance liquid chromatography. Ten nanograms of the vasodilator are present in the extract of a pair of sand fly salivary glands. It has 500 times the vasodilatory activity of calcitonin gene-related peptide, pr...
