In vivo near-infrared fluorescence imaging of Leishmania amazonensis expressing infrared fluorescence protein (iRFP) for real-time monitoring of cutaneous leishmaniasis in mice.

The use of Leishmania amazonensis-infected BALB/c mice is an important model for the study of experimental cutaneous leishmaniasis. Here we report the development of a non-invasive method to directly evaluate and measure parasite burden during the course of the infection, based on the near-infrared fluorescence detection of a recombinant L. amazonensis strain.

A proteomic insight into the effects of the immunomodulatory hydroxynaphthoquinone lapachol on activated macrophages.

We report the effect of an immunomodulatory and anti-mycobacterial naphthoquinone, lapachol, on the bi-dimensional patterns of protein expression of toll-like receptor 2 (TLR2)-agonised and IFN-γ-treated THP-1 macrophages. This non-hypothesis driven proteomic analysis intends to shed light on the cellular functions lapachol may be affecting. Proteins of both cytosol and membrane fractions were analysed.
