Background Among the several challenges faced by bloodsucking arthropods, the vertebrate hemostatic response against blood loss represents an important barrier to efficient blood feeding. Here we report the first inhibitor of collagen-induced platelet aggregation derived from the salivary glands of a black fly (Simulium nigrimanum), named Simplagrin. Methods and Findings Simplagrin was expressed in mammalian cells and purified by affinity-and size-exclusion chromatography. Light-scattering… 

ADP binding by the Culex quinquefasciatus mosquito D7 salivary protein enhances blood feeding on mammals

It is suggested that the ADP-binding function acquired by CxD7L1 evolved to enhance blood-feeding in mammals, where ADP plays a key role in platelet aggregation.

Inhibitors of Platelet Adhesion to VWF and Collagen

This chapter describes different compounds that inhibit initial platelet adhesion and demonstrates that inhibition of these interactions holds great promise as an antithrombotic strategy without significant increase of the bleeding risk.

Results highlight L7-PGA as an effective inhibitor of arterial thrombus formation via blocking exposed collagen surface, which would be helpful for the development of novel antithrombotic nanomedicine.

Biochemical characterization of AeD7L2 and its physiological relevance in blood feeding in the dengue mosquito vector, Aedes aegypti

The different ligand specificity and affinities of AeD 7L1 and AeD7L2 matched the experimental observations from studying their effects on vasoconstriction and platelet aggregation, which confirm their role in preventing host hemostasis.

Anti-Thrombotic, Anti-Oxidant and Haemolysis Activities of Six Edible Insect Species

Of the six insect extracts, TM and AM extracts exhibited potent haemolytic activity, suggesting that edible insects have considerable potential not just as a food source but as a novel bio-resource as well.

Novel function acquired by the Culex quinquefasciatus mosquito D7 salivary protein enhances blood feeding on mammals

The novel ADP-binding function acquired by CxD7L1 evolved to enhance blood feeding in mammals where ADP plays a key role in platelet aggregation, and it is demonstrated that these two D7 long proteins inhibit human platelets aggregation in ex vivo experiments.

Potential pharmacological use of salivary compounds from hematophagous organisms

The saliva of hematophagous insects has a wide variety of molecules that constitute a source of research and have an incalculable potential for the discovery of compounds that could be pharmacologically useful.

Glandular Matrices and Secretions: Blood-Feeding Arthropods

Blood-feeding evolved independently in various arthropod lineages and this is evident in the compositions of the secretory component of their salivary gland transcriptomes (sialomes). Salivary

An insight into the sialotranscriptome and virome of Amazonian anophelines

The sialotranscriptome study reported here provided novel data on four New World anopheline species and allowed to extend knowledge on the salivary repertoire of A. darlingi species, including novel viruses following analysis of the transcriptomes.



Aegyptin, a Novel Mosquito Salivary Gland Protein, Specifically Binds to Collagen and Prevents Its Interaction with Platelet Glycoprotein VI, Integrin α2β1, and von Willebrand Factor*

Aegyptin, a member of the family of 30-kDa salivary allergens from Aedes aegypti, is molecularly and functionally characterized and was shown to specifically block collagen-induced human platelet aggregation and granule secretion.

Black fly (Diptera:Simuliidae) salivary secretions: importance in vector competence and disease.

The likely possibility that effective pathogen transmission relies on vector saliva may complement present efforts aimed at target epitopes of O. volvulus or identify additional molecules to be investigated as part of a "river blindness" vaccine cocktail.

New insights into von Willebrand disease and platelet function.

Type 2B VWD is of special interest as it may provide further insight into the mechanism by which VWF promotes the adhesion of platelets to a thrombogenic surface under conditions of high shear stress.

Platelet-collagen interaction: is GPVI the central receptor?

Recent developments in understanding platelet-collagen interactions are discussed and possible mechanisms for how GPVI acts in concert with other receptors and signaling pathways to initiate hemostasis and arterial thrombosis are proposed.

Lundep, a Sand Fly Salivary Endonuclease Increases Leishmania Parasite Survival in Neutrophils and Inhibits XIIa Contact Activation in Human Plasma

It is hypothesized that Lundep helps the parasite to establish an infection by allowing it to escape from the leishmanicidal activity of NETs early after inoculation and may also assist blood meal intake by lowering the local viscosity caused by the release of host DNA and as an anticoagulant by inhibiting the intrinsic pathway of coagulation.

Identification of the active region responsible for the anti-thrombotic activity of anopheline anti-platelet protein from a malaria vector mosquito

Results indicated that the essential moiety of AAPP for collagen binding and anti-thrombotic activity was in the region encoded by exon 3–4, which is highly conserved among the counterpart regions of other mosquito species.

Analyses of cDNA and recombinant protein for a potent vasoactive protein in saliva of a blood-feeding black fly, Simulium vittatum.

Recombinant SVEP is a novel salivary-gland-derived vasoactive protein that may be essential for blood feeding by black flies and could potentially enhance transmission of filarial parasites.

An insight into the sialotranscriptome of Simulium nigrimanum, a black fly associated with fogo selvagem in South America.

The uncovering of this sialotranscriptome provides a platform for testing pemphigus patient sera against recombinant salivary proteins from S. nigrimanum and for the discovery of novel pharmacologically active compounds.

The Effects of an Inhibitor of Diglyceride Lipase on Collagen-Induced Platelet Activation

A novel DGL blocker (OMDM-188) inhibited collagen-, but not arachidonic acid–induced aggregation and TxA2 synthesis, suggesting a role for a pathway involving phospholipase C liberating DG from membrane phospholIPids in response to minimally activating concentrations of collagen.
