Transcriptome exploration of the sex pheromone gland of Lutzomyia longipalpis (Diptera: Psychodidae: Phlebotominae)
Parasites & Vectors 2013, 6:56 (7 March 2013)
This study constitutes the first transcriptomic analysis exploring the repertoire of genes expressed in the tissue containing the L. longipalpis pheromone gland. Using a comparative approach, a set of molecules potentially present in the mevalonate pathway emerge as interesting subjects for further study regarding their association to pheromone biosynthesis.

Two biochemically distinct lipophosphoglycans from Leishmania braziliensis and Leishmania infantum trigger different innate immune responses in murine macrophages
Parasites & Vectors 2013, 6:54 (7 March 2013)
The role of the L. braziliensis and L. infantum LPG during interaction with macrophages was assessed. The polymorphisms of the glycan moieties resulted in differential activation of NFKB and inflammatory mediators, suggesting an important role of LPG in the immune response.

Trypsin-like serine peptidase profiles in the egg, larval, and pupal stages of Aedes albopictus
Ana Paula de Barros
Parasites & Vectors 2013, 6:50 (27 February 2013)
In this study, the active trypsin-like serine peptidases profile of pre-imaginal stages of Aedes albopictus were characterized. Egg, larval and pupal stages of this species express a complex proteolytic profile with optimal activity at alkaline pH and over a wide range of temperature. By a comparative analysis of the differential expression of peptidase activities, it was possible to detect and assign specific trypsin activities to each pre-imaginal stage. Image: Trypsin-like serine peptidases profile exhibited by egg, larva and pupa of Aedes albopictus.

Networking the host immune response in Plasmodium vivax malaria
Malaria Journal 2013, 12:69 (21 February 2013)
The clinical outcome of an infection is a consequence of the interaction of multiple factors - parasite, environmental and host factors. This study is a network analysis of different clinical presentations of vivax malaria to identify patterns of association between various candidate biomarkers and the clinical outcome.

Absence of CCR5 increases neutrophil recruitment in severe herpetic encephalitis

BMC Neuroscience 2013, 14:19 (7 February 2013)
The absence of the chemokine receptor CCR5 in mice inoculated with herpes simplex virus 1 leads to a lower viral load and high neutrophil recruitment, thought to play a role in the pathogenesis of neuroaxonal damage in herpetic encephalitis.
