1. Anti-complement activity in salivary glands and midgut of Chagas disease vector, Panstrongylus megistus (Hemiptera, Triatominae)
ABSTRACT The triatomine insect Panstrongylus megistus , one of the most important Chagas disease vectors in Brazil, presents salivary molecules pharmacologically active to counteract homeostatic responses from the host, including inhibitors of the human complement system, a major effector of immune responses. The aim of the present study was to investigate t

2. Efeito da saliva de Aedes aegypti sobre a diferenciação, maturação e função de células dendríticas e na proliferação de linfócitos T. / Effect of Aedes aegypti saliva on the differentiation, maturation and function of dendritic cells and on T lymphocyte proliferation.
Mosquitos são os mais importantes vetores de patógenos humanos, transmitindo um amplo espectro de doenças infecciosas emergentes e reemergentes. Nesse cenário, o mosquito Aedes aegypti está entre as espécies mais relevantes. No presente estudo investigamos as atividades do extrato de glândula salivar (EGS) desse mosquito vetor na biologia das células

3. Caracterização do parasitismo por Ornithodoros brasiliensis (Chelicerata: Argasidae) e da toxicose induzida em humanos e animais
Ticks are blood-sucking arthropods distributed worldwide and able to parasitize almost all terrestrial vertebrate animals. Ticks are considered a great hazard for both public health and animal breeding due to their ability to transmit infectious diseases and to induce direct toxic effects leading to clinical disturbances. Ornithodoros brasiliensis, popularly

4. Avaliação da Imunogenicidade de Dois Novos Imunobiológicos Candidatos a Vacina Contra Leishmaniose Visceral Canina
Considering the importance of immunoprophylactic strategies for the control of visceral leishmaniasis, and the lack of studies concerning the cellular and humoral events that occur during vaccination in dogs, we have attempted to evaluate the immune response of a promising new vaccines candidate against canine visceral leishmaniasis (CVL). Thirty five mongre

5. Salivary gland extracts from the deerfly contain a potent inhibitor of platelet aggregation.
Salivary gland extracts of the deerfly contain a potent inhibitor of platelet aggregation, which assists the insect in obtaining a blood meal. The extract prevents platelet aggregation induced by ADP, thrombin, and collagen and inhibits fibrinogen binding to the glycoprotein IIb/IIIa receptor on platelets. The active component in deerfly salivary gland extra

6. Tick Salivary Gland Extract Inhibits Killing of Borrelia afzelii Spirochetes by Mouse Macrophages
Salivary gland extract (SGE) from Ixodes ricinus ticks inhibited the killing of Borrelia afzelii spirochetes by murine macrophages. SGE also reduced the production of two major defense molecules of phagocytes, superoxide and nitric oxide. It is likely that the suppression of macrophage microbicidal mechanisms contributes to the inhibitory effect of tick sali

7. Tick salivary gland extract and interleukin-2 stimulation enhance susceptibility of lymphocytes to infection by Theileria parva sporozoites.
Intracellular parasites show host cell specificity, and precise information on the range of host cells is a prerequisite for the identification of host molecules that account for the specificity and are involved in entry processes. The sporozoite stage of the tick-borne protozoan parasite Theileria parva binds to and enters bovine lymphocytes, but precise in

8. Analysis of Candida albicans adhesion to salivary mucin.
Clearance of Candida albicans from the oral cavity is thought to be mediated via specific receptor-ligand interactions between salivary constituents and the fungus. Since surfaces in the oral cavity are normally coated with a saliva-derived pellicle, specific interactions between salivary constituents and C. albicans may also contribute to adhesion of C. alb

9. Effect of sialoadenectomy and salivary gland extracts on gastrointestinal mucosal growth and gastrin levels in the rat.
We have examined gastrointestinal mucosal growth 30 days after surgical removal of the submandibular-sublingual salivary glands and ligation of the parotid ducts of rats. The rate of [3H]thymidine uptake in vitro as an estimation of DNA synthesis and the content of DNA and RNA were examined in the oxyntic, duodenal and proximal colonic mucosa. DNA synthesis,

10. Mx1-Based Resistance to Thogoto Virus in A2G Mice Is Bypassed in Tick-Mediated Virus Delivery
The interferon-induced mouse Mx1 protein has intrinsic antiviral activity against orthomyxoviruses, including Thogoto virus. Thus, Mx1+ A2G mice are apparently resistant to infection following needle- or tick-borne virus challenge. However, tick-borne challenge and, to a lesser degree, injection of virus mixed with tick salivary gland extract resulted in vir

11. Amino acid sequence of Fel dI, the major allergen of the domestic cat: protein sequence analysis and cDNA cloning.
The complete primary structure of Fel dI (International Union of Immunological Societies nomenclature), the major allergen produced by the domestic cat, Felis domesticus, was determined by protein sequence analysis and cDNA cloning. Protein sequencing of Fel dI from an immunoaffinity-purified extract of house dust revealed that the allergen is composed of tw

12. THE NERVE GROWTH FACTOR: PURIFICATION AS A 30,000-MOLECULAR-WEIGHT PROTEIN*
The nerve growth factor protein was purified over 100-fold from adult mouse salivary glands. The first step was a gel filtration on Sephadex G-100 at pH 7.5 of the aqueous gland extract. After gel filtration, most of the NGF activity was eluted in the 80,000-90,000-molecular-weight region (G-100 pool). The G-100 pool was dialyzed at pH 5.0 and fractionated b
