Zoonotic cutaneous leishmaniasis caused by Leishmania major is a most common type of vector-borne disease in Iran. The pentavalent antimonial drugs have been used in the treatment of cutaneous leishmaniasis for a long time, but drug resistance and some of serious side effects have been reported. Thus, discovery and development of new therapeutic candidates are needed. The CM11 peptide ...
Experimental chronic (45-day-old) skin lesion in hamster hind foot induced by Leishmania (Viannia) lainsoni infection showed the presence of promastigote forms in the tissue, inside parasitophorous vacuoles, as assessed by transmission electron microscopy. Experimental in vitro interaction (24 and 48 h) between Leishmania (V.) lainsoni and J774-G8 macrophage cells also demonstrated the same pro...
Antisense oligonucleotides have been considered as inhibitors of growth of intracellular parasites such as Leishmania, but only limited inhibition has been observed in vitro. We have encapsulated an antisense oligonucleotide, complementary to the Leishmania universal miniexon sequence, in cationic liposomes. Low concentrations (4 microM) of encapsulated oligonucleotides specifically reduced the...
The in vitro trypanocidal activity of a 1 : 4 mixture of lupenone and caryophyllene oxide confirmed a synergistic effect of the terpenoids against epimastigotes forms of T. cruzi (IC50 = 10.4 μ g/mL, FIC = 0.46). In addition, testing of the terpenoid mixture for its capacity to reduce the number of amastigote nests in cardiac tissue and skeletal muscle of infected mice showed a reduction of mo...
Cutaneous leishmaniasis is endemic in certain tropical and sub-tropical regions, and is sometimes encountered as an imported disease in Norway. The disease is characterized by chronic and painless, but often disfiguring, ulcers that regress after some months to years, leaving atrophic scars. Diagnosis is established by demonstrating amastigote Leishmania bodies by microscopy of Giemsa-stained s...
In mammalian hosts, Leishmania sp. parasites are obligatory intracellular organisms that invade macrophages and dendritic cells (DC), where they reside in endocytic organelles termed parasitophorous vacuoles (PV). Most of the present knowledge of the characteristics of PV harboring Leishmania sp. is derived from studies with infected macrophages. Since DC play a key role in host resistance to l...
