Axenic cultivation and characterization of Leishmania mexicana amastigote-like forms.
A new method is described which has made possible the long-term axenic cultivation of Leishmania mexicana amastigote-like forms in Schneider's Drosophila medium supplemented with 20% (v/v) foetal calf serum. Unlike previous methods, it utilizes direct culture of parasites obtained from the lesions of infected animals rather than adaptation of promastigotes in vitro. Ultrastructural (possession ...
متن کاملNaloxonazine, an Amastigote-Specific Compound, Affects Leishmania Parasites through Modulation of Host-Encoded Functions
Host-directed therapies (HDTs) constitute promising alternatives to traditional therapy that directly targets the pathogen but is often hampered by pathogen resistance. HDT could represent a new treatment strategy for leishmaniasis, a neglected tropical disease caused by the obligate intracellular parasite Leishmania. This protozoan develops exclusively within phagocytic cells, where infection ...
متن کاملCysteine Peptidase B Regulates Leishmania mexicana Virulence through the Modulation of GP63 Expression
Cysteine peptidases play a central role in the biology of Leishmania. In this work, we sought to further elucidate the mechanism(s) by which the cysteine peptidase CPB contributes to L. mexicana virulence and whether CPB participates in the formation of large communal parasitophorous vacuoles induced by these parasites. We initially examined the impact of L. mexicana infection on the traffickin...
متن کاملExosomes: Mediators of Immune Regulation
Extracellular Vesicles, including exosomes, are small membrane fragments released from many cell types, like Mesenchymal Stem Cells (MSCs). They were recognized as a mechanism of intercellular communication. They can transfer proteins, lipids and nucleic acids to other cells. Thus, they have many physiological (angiogenesis, coagulation and tissue repair, etc.) and pathological (e.g. in autoimm...
متن کاملThe structure of Leishmania major amastigote lipophosphoglycan.
Intracellular amastigotes of Leishmania major produce 6 x 10(4) copies/cell of a lipophosphoglycan (LPG) that is structurally distinct from the LPG produced by the extracellular promastigote form of L. major, Leishmania donovani, and Leishmania mexicana (reviewed by McConville, M. J. (1991) Cell Biol. Int. Rep. 15, 779-798). L. major amastigote LPG is composed of a lysoalkyl phosphatidylinosito...
