Activation of artemisinin and heme degradation in Leishmania tarentolae promastigotes: A possible link

Expressional Comparison Between Episomal and Stable Transfection of a Selected tri-fusion Protein in Leishmania tarentolae

  Introduction: Leishmania tarentolae (L. tarentolae) is a nonpathogenic species of Leishmania genus that can be used as an expression system to produce immunogenic proteins or epitopes in vivo acting as an efficient and safe recombinant live vector in vaccinology. Cysteine proteases (CPs) are one group of Family C1 peptidases in Leishmania that are important for survival of the parasite within...

Artemisinin and heme.

A recent Letter to the Editor (R. K. Haynes, D. Monti, D. Taramelli, N. Basilico, S. Parapini, and P. Olliaro, Letter, Antimicrob. Agents Chemother. 47:1175, 2003) presented cogent evidence that artemisinin and its derivatives do not inhibit hemozoin formation in vitro. However, the authors misinterpret these data to conclude that “binding of artemisinins with Fe(III)PPIX is not necessary for a...

Recombinant protein expression in Leishmania tarentolae.

A variety of recombinant protein expression systems have been developed for heterologous genes in both prokaryotic and eukaryotic systems such as bacteria, yeast, mammals, insects, transgenic animals, and plants. Recently Leishmania tarentolae, a trypanosomatid protozoan parasite of the white-spotted wall gecko (Tarentola annularis), has been suggested as candidate for heterologous genes expres...

The status of Leishmania tarentolae/Trypanosoma platydactyli.

Taxonomic studies and classification of Leishmania species have developed rapidly in recent years, but controversy still surrounds the relationships between those species infecting lizards and those infecting mammals. Some authorities maintain that the leishmanias o f lizards form a sufficiently distinct group to be ranked as a separate genus - Sauroleishmania(1,2) - while Wallbanks et al. have...
