Hexanic, methanolic, and hydroalcoholic extracts, and 34 isolated compounds from Vitex polygama Cham. (Lamiaceae, formely Verbenaceae) and Siphoneugena densiflora O. Berg (Myrtaceae) were screened for their trypanocidal effects on bloodstream forms of Trypanosoma cruzi and T brucei, as well as for their enzymatic inhibitory activities on glycosomal glyceraldehyde-3-phosphate dehydrogenase (gGAP...
زمینه و هدف : پروتئین اریتروپویتین انسانی هورمونی گلیکوزیله با وزن مولکولی 40 کیلو دالتون است که در کلیه سنتز شده و در تکثیر و تمایز اریتروسیت‌ها نقش دارد. این پروتئین دارویی با نام تجاری «اپویتین» شناخته شده و کاربرد موثری در درمان آنمی، سرطان و عفونت‌های ناشی از HIV ایفاء می‌کند. این مطالعه به منظور ارزیابی استفاده از میزبان انگلی لیشمانیا تارانتولا (Leishmania tarentolae) به منظور تولید فرم ...
Purified mitochondria of Leishmania tarentolae contain 3'-terminal uridylyltransferase and RNA ligase activities which can be solubilized by detergent lysis of the organelle. Run-off transcription of maxicircle and minicircle DNA also occurs in intact and Triton-lysed mitochondria, using [32P]GTP as the labeled precursor. Heparin inhibits the solubilized terminal uridylyltransferase activity bu...
Visceral leishmaniasis (VL) is a major fatal disease prevalent in North-East India, caused by a protozoan parasite Leishmania donovani. The parasite multiplies and thrives inside mammalian macrophages and is transmitted by the bite of the sandfly. Due to the unsatisfactory treatment measures, increasing drug resistance and the advent of HIV-Leishmania co-infection there has been an urgent need ...
Trypanosomatid protozoans depend upon exogenous sources of pteridines (pterins or folates) for growth. A broad spectrum pteridine reductase (PTR1) was recently identified in Leishmania major, whose sequence places it in the short chain alcohol dehydrogenase protein family although its enzymatic activities resemble dihydrofolate reductases. The properties of PTR1 suggested a role in essential pt...
Instability is an intriguing characteristic of many protist genomes, and trypanosomatids are not exception in this respect. Some regions trypanosomatid genomes evolve fast. For instance, the mitochondrial (kinetoplast) genome consists fairly conserved maxicircle minicircle molecules that can, nevertheless, possess high nucleotide substitution rates between closely related strains. Recent experi...
