Generation of an antibody that recognizes Plasmodium chabaudi cysteine protease (chabaupain-1) in both sexual and asexual parasite life cycle and evaluation of chabaupain-1 vaccine potential

Malaria cysteine proteases have been shown to be immunogenic and are being exploited as serodiagnostic markers, drug and vaccine targets. Several Plasmodium spp. cysteine proteases have been described and the best characterized of these are the falcipains, a family of papain-family enzymes. Falcipain-2 and falcipain-3 act in concert with other proteases to hydrolyze host erythrocyte hemoglobin in the parasite food vacuole.

Canine leishmaniosis. Modulation of macrophage/lymphocyte interactions by L. infantum.

  • Autores: Alexandre-Pires G, Cartaxeiro C, da Fonseca IP, de Brito TV, Diaz S, Martins C, Rodrigues A, Santos-Gomes GM, Silva MJ

Canine leishmaniosis, caused by Leishmania infantum, is a systemic disease with variable clinical signs and a progressive evolution. This disease is characterized by impaired T cell-mediated immune response, which has been associated with disease chronicity and high mortality. Protective immunity against leishmaniosis is thought to be mediated by T cell and cytokine production.

Realities and professional expectations of medical students attending Guinea Bissau’s medical school in 2007 school year.

In Guinea Bissau, the majority of university level professionals are still being trained abroad and most of them do not return to their country. This was a major incentive for creating Guinea Bissau’s Medical School.

BACKGROUND:
The purpose of this paper is to describe and analyze the professional expectations of medical students during the 2007-2008 academic year at the public medical schools of Angola, Guinea-Bissau and Mozambique, and to identify their social and geographical origins, their professional expectations and difficulties relating to their education and professional future.

New insights into neutrophil and Leishmania infantum in vitro immune interactions

  • Autores: Alexandre-Pires G, Correia I, Helena Ferronha M, Marques CS, Martins C, Passero LFD, Rodrigues A, Rodrigues OR, Santos-Gomes GM, Tomas AM, Vale-Gato I

The interaction between polymorphonuclear leukocytes (PMN) or neutrophils and Leishmania became an interesting focus of research, since PMN turn out to be essential cells in transiently hosting the parasites.

Adaptive Potential of Hybridization among Malaria Vectors: Introgression at the Immune Locus TEP1 between Anopheles coluzzii and A. gambiae in ‘Far-West’ Africa

  • Autores: Caputo B, Dinis J, Gordicho V, Mancini E, Petrarca V, Pombi M, Rodrigues A, Spinaci MI, Vicente JL, Weetman D

“Far-West” Africa is known to be a secondary contact zone between the two major malaria vectors Anopheles coluzzii and A. gambiae. We investigated gene-flow and potentially adaptive introgression between these species along a west-to-east transect in Guinea Bissau, the putative core of this hybrid zone.

Immunization with the Leishmania infantum recombinant cyclophilin protein 1 confers partial protection to subsequent parasite infection and generates specific memory T cells

Control of zoonotic visceral leishmaniosis can be achieved using several available drugs. These drugs present high toxicity and require longer treatment regimens which complicate compliance to the treatment. Other control measures directed to the vector or the reservoirs are useful tools to restrain the spreading of this disease but the effects are transitory.

First report of an exophilic Anopheles arabiensis population in Bissau City, Guinea-Bissau: recent introduction or sampling bias?

  • Autores: Caputo B, Della Torre A, Dinis J, Gordicho V, Palsson K, Pinto J, Pombi M, Rodrigues A, Seixas G, Sousa CA, Vicente JL, Weetman D
  • Ano de Publicação: 2014

  • Link: http://www.malariajournal.com/content/13/1/423

This study reports for the first time the presence of An. arabiensis in Antula, a suburb of Bissau city, the capital of Guinea Bissau, where high levels of hybridization between Anopheles coluzzii and An. gambiae have been reported. Given that previous surveys in the area, based on indoor collections, did not sample An. arabiensis, the possibility of a recently introduced exophilic population was investigated.
