"Mannose glycans as key players in trained immunity: A novel anti-tumoral catal...
Almeida, P; Alves, I; Fernandes, Â; Lima, C; Freitas, R; Braga, I; Correia, J; Jerónimo, C; Pinho, SSCell wall glycans isolated from microorganisms are long known to provoke strong immune responses piloted by innate immune cell populations, including monocytes, in the context of Trained Immunity (TI). However, the contribution of yeast-derived mannan in the reprogramming of monocytes remains ill-defined. Here, we demonstrated that TI is often accompanied by an altered gene expression profile of selected glycan...

Barradas, PF; Lima, C; Cardoso, L; Amorim, I; Gärtner, F; Mesquita, JRTick-borne agents constitute a growing concern for human and animal health worldwide. Hyalomma aegyptium is a hard tick with a three-host life cycle, whose main hosts for adults are Palearctic tortoises of genus Testudo. Nevertheless, immature ticks can feed on a variety of hosts, representing an important eco-epidemiological issue regarding H. aegyptium pathogens circulation. Hyalomma aegyptium ticks are vecto...

Barradas, PF; Mesquita, JR; Lima, C; Cardoso, L; Alho, AM; Ferreira, P; Amorim, I; de Sousa, R; Gärtner, FThe dissemination of vector arthropods harbouring zoonotic pathogens through the uncontrolled transboundary trade of exotic and pet animals poses an important threat to Public Health. In the present report, we describe the introduction of pathogenic Rickettsia africae and R. aeschlimanni in ticks removed from imported tortoises in Qatar. A total of 21 ticks were collected from pet spur-thighed tortoises (Testud...
The Use of Specific Serological Biomarkers to Detect CaniLeish Vaccination in Dogs
Lima, C; Santarém, N; Nieto, J; Moreno, J; Carrillo, E; Bartholomeu, D; Bueno, L; Fujiwara, R; Amorim, CMPG; Cordeiro-da-Silva, ACanine leishmaniosis (CanL) prevention in the Mediterranean basin is considered essential to stop human zoonotic visceral leishmaniasis. In this context, vaccination of dogs is expected to have a significant impact in disease control. CaniLeish® (Virbac Animal Health) is one of a few CanL vaccines that are at this moment licensed in Europe. This vaccine contains purified excreted-secreted proteins of Leishmania...

The use of Escherichia coli total antigens as a complementary approach to addre...
Lima, C; Mesquita, J; Brancal, H; Vahlenkamp, T; Teixeira, AR; Cardoso, L; Amorim, C; Santarém, N; Cordeiro-da-Silva, ACanine leishmaniosis (CanL) is a major veterinary concern and a public health issue. Serological data are essential for disease management. Several antigens used in serological assays have specificity related problems preventing relevant seropositivity values establishment. Herein we report significant seropositivity level disparity in a study cohort with 384 dogs from eight countries, for antigens traditionall...
