“…Also absent are members of the 62-kDa and 34-kDa families, 30-kDa antigen, basic 7.6-kDa peptide, and basic 3.8-kDa peptide. Many of these absent families were abundantly transcribed in AEdes and Culex transcriptomes (Arca et al, 2002;Calvo et al, 2006a;James et al, 1991;Valenzuela et al, 2002a), and their complete absence in over 1,000 transcripts is significant, indicating that these families may play a role in blood feeding. Expression of these proteins in hemostasis and inflammation bioassays may help to uncover their function.…”

All adult mosquitoes take sugar meals, and most adult females also take blood meals to develop eggs. Salivary glands (SG) of males are thus much smaller and do not contain many of the antihemostatic and antiinflammatory compounds found in females. In the past 5 years, transcriptome analyses have identified nearly 70 different genes expressed in adult female SG. For most of these, no function can be assigned in either blood or sugar feeding. Exceptionally, Toxorhynchites mosquitoes are unusual in that they never feed on blood, and the SG of adults are identical in both sexes. Transcriptome analysis of the adult SG of this mosquito was performed to increase knowledge of the evolution of blood feeding-and to identify polypeptide families associated with sugar feeding-in mosquitoes.

“…Mosquitoes, like all haematophagous arthropods, have evolved mechanisms to effectively neutralize host haemostatic responses, based upon the release of saliva into the feeding site. Saliva is a pharmacologic cocktail of secreted molecules, principally proteins, that can affect vascular constriction, blood coagulation, platelet aggregation, inflammation, immunity, and angiogenesis (Arca et al 1999, Arca et al 2002, Arca et al 2005, Billingsley et al 2006, Calvo et al 2004, Calvo et al 2006a, Calvo et al 2006b, Calvo and Ribeiro 2006, Champagne 2004, Champagne et al 1995, Cross et al 1994, James et al 1991, Kerlin and Hughes 1992, Mellink and Vos 1977, Ribeiro 1987, 1989b, 1992, Ribeiro et al 2000, Ribeiro and Francischetti 2001, 2003, Ribeiro and Nussenzveig 1993, Ribeiro et al 1994, Stark and James 1998, Suwan et al 2002, Valenzuela et al 2002, Wanasen et al 2004, Wasserman et al 2004, Zeidner et al 1999. The saliva of all species of haematophagous arthropod analyzed to date contains at least one anticlotting, one anti-platelet, and one vasodilatory substance.…”

SUMMARYArthropod-borne viruses have emerged as a major human health concern. Viruses transmitted by mosquitoes are the cause of the most serious and widespread arbovirus diseases worldwide and are ubiquitous in both feral and urban settings. Arboviruses, including dengue and West Nile virus are injected into vertebrates within mosquito saliva during mosquito feeding. Mosquito saliva contains anti-haemostatic, anti-inflammatory and immunomodulatory molecules that facilitate the acquisition of a blood-meal. Collectively, studies investigating the effects of mosquito saliva on the vertebrate immune response suggest that at high concentrations salivary proteins are immmunosuppressive, whereas lower concentrations modulate the immune response; specifically, T H 1 and antiviral cytokines are down-regulated, while T H 2 cytokines are unaffected or amplified. As a consequence, mosquito saliva can impair the anti-viral immune response thus affecting viral infectiousness and host survival. Mounting evidence suggests that this is a mechanism whereby arbovirus pathogenicity is enhanced. In a range of disease models, including various hosts, mosquito species, and arthropodborne viruses, mosquito saliva and/or feeding is associated with a potentiation of virus infection. Compared to arbovirus infection initiated in absence of the mosquito or its saliva, infection including mosquito saliva leads to an increase in virus transmission, host susceptibility, viraemia, disease progression, and mortality.Keywords arthropod-borne virus; mosquito saliva; immunomodulation; disease enhancement Most arthropod-borne (arbo)viruses of public health significance are mosquito-borne, and thus transmitted to vertebrates via the feeding of an infected mosquito.

López: análisis bioinformático y datos experimentales inéditos Todos los autores contribuyeron en igual medida a la redacción del manuscrito. La urticaria papular es una enfermedad alérgica causada por la picadura de insectos, la cual predomina en el trópico. El objetivo de esta revisión fue profundizar en sus aspectos epidemiológicos e inmunológicos, particularmente con base en datos publicados en Latinoamérica. Se hizo una revisión no sistemática mediante la búsqueda electrónica de artículos sobre la epidemiología de la urticaria papular, las características entomológicas de los agentes causales y los mecanismos inmunológicos asociados. Según los diversos reportes de centros médicos de Latinoamérica la urticaria papular es frecuente; el único estudio de prevalencia publicado indica que afecta a una cuarta parte de los niños escolares de Bogotá. Hay información sobre la relación causal entre la exposición domiciliaria a la pulga, la pobreza y la urticaria papular en Bogotá, una ciudad representativa de las altitudes andinas. No hay estudios que indaguen directamente sobre los insectos causales en zonas cálidas, aunque se sospecha clínicamente de los mosquitos Aedes aegypti y Culex quinquefasciatus. En cuanto a su patogenia, se destaca la participación de mecanismos celulares que involucran las células colaboradoras Th2, lo cual explica que sea una condición de hipersensibilidad retardada. El papel de la inmunoglobulina E (IgE) en la urticaria papular no está tan claro. Se desconocen los antígenos derivados de los insectos que causan la enfermedad, aunque se plantea que existen moléculas comunes de reacción cruzada entre los insectos, tales como el alérgeno Cte f 2 en la pulga, y sus homólogos en los mosquitos. La urticaria papular es una condición frecuente en Latinoamérica que debe investigarse en profundidad. La caracterización inmunológica de los componentes moleculares que causan esta condición puede resolver interrogantes sobre su etiología y su patogenia.

The objective of this review was to deepen on epidemiological and immunological aspects of this disease, focused on data published in Latin American countries. We conducted a non-systematic review of the literature through electronic search on the epidemiology of papular urticaria, the entomological characteristics of the causative agents and associated immunological mechanisms. Several reports from medical centers suggest that papular urticaria is common in Latin America. Only one epidemiological survey designed to estimate prevalence of papular urticaria has been published, reporting that about a quarter of children under six years of age is affected by this condition in Bogotá. There is evidence on the ca...
