Characterisation of Geranylgeranyl Diphosphate Synthase from the Sandfly Lutzomyia Longipalpis

Insect Biochemistry and Molecular Biology, 2023
Leishmaniasis is a debilitating and often fatal neglected tropical disease. Males from sub-populations of the Leishmania-harbouring sandfly, Lutzomyia longipalpis, produce the diterpene sex and aggregation pheromone, sobralene, for which geranylgeranyl diphosphate (GGPP) is the likely isoprenoid precursor.

Ecology of Lutzomyia longipalpis and Lutzomyia migonei in an endemic area for visceral leishmaniasis [PDF]

Revista Brasileira de Parasitologia Veterinária, 2014
The main vector for visceral leishmaniasis (VL) in Brazil is Lutzomyia longipalpis. However, the absence of L. longipalpis in a region of autochthonous VL demonstrates the participation of other species in the transmission of the parasite. Studies conducted in La Banda, Argentina, and São Vicente Férrer, Pernambuco State, Brazil, have correlated the ...

SALO, a novel classical pathway complement inhibitor from saliva of the sand fly Lutzomyia longipalpis. [PDF]

, 2016
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 ...

Colonisation resistance in the sand fly gut:Leishmania protects Lutzomyia longipalpis from bacterial infection [PDF]

, 2014
BACKGROUND: Phlebotomine sand flies transmit the haemoflagellate Leishmania, the causative agent of human leishmaniasis. The Leishmania promastigotes are confined to the gut lumen and are exposed to the gut microbiota within female sand flies.
