Bidirectional Interaction Between Liposomal Amphotericin B Pharmacokinetics and Parasite Dynamics in Patients With Post‐Kala‐Azar Dermal Leishmaniasis: Potential Implications for Optimal Dosing

Clinical Pharmacology &Therapeutics, EarlyView.
Post‐kala‐azar dermal leishmaniasis (PKDL) involves a high macrophage burden in which the Leishmania parasites reside. Liposomal amphotericin B (LAmB) plays a key role in the treatment of PKDL. The mononuclear phagocyte system (MPS) is crucial in the distribution of liposomal drugs as well as the leishmaniasis pathophysiology.

Gene expression in Leishmania is regulated predominantly by gene dosage [PDF]

, 2017
Leishmania tropica, a unicellular eukaryotic parasite present in North and East Africa, the Middle East, and the Indian subcontinent, has been linked to large outbreaks of cutaneous leishmaniasis in displaced populations in Iraq, Jordan, and Syria. Here,

Paromomycin: Uptake and resistance in Leishmania donovani [PDF]

Molecular and Biochemical Parasitology, 2009
Paromomycin is currently in phase IV clinical trials against leishmaniasis. In the present work we elucidate the effect and mechanism of uptake of paromomycin in Leishmania donovani. The in vitro sensitivities of both promastigotes and amastigotes were determined to this aminoglycoside. Association of paromomycin with L.

Leishmania donovani's protein tyrosine phosphatases interact with DUF21 and respond to environmental magnesium

The FEBS Journal, EarlyView.
The Leishmania phosphatase PTP1, and possibly the genetically similar PTP2, interacts with the Leishmania transmembrane protein DUF21. When both ptp1 and ptp2 are knocked out of Leishmania (LdΔPTP1/2), the parasite can no longer survive without magnesium in vitro and has reduced viability in the host macrophage. Conversely, in duf21 knockout (LdΔDUF21),

CRISPR-Cas9-Mediated Genome Editing in Leishmania donovani

mBio, 2015
The prokaryotic CRISPR (clustered regularly interspaced short palindromic repeat)-Cas9, an RNA-guided endonuclease, has been shown to mediate efficient genome editing in a wide variety of organisms.

Comparison of Bloodmeal Digestion and the Peritrophic Matrix in Four Sand Fly Species Differing in Susceptibility to Leishmania donovani. [PDF]

PLoS ONE, 2015
The early stage of Leishmania development in sand flies is closely connected with bloodmeal digestion. Here we compared various parameters of bloodmeal digestion in sand flies that are either susceptible (Phlebotomus argentipes and P.

The recombinant cysteine proteinase B (CPB) from Leishmania braziliensis and its domains: promising antigens for serodiagnosis of cutaneous and visceral leishmaniasis in dogs. [PDF]

, 2019
Leishmaniasis represents a group of parasitic diseases caused by a protozoan of the genus Leishmania and is widely distributed in tropical and subtropical regions.

Ultrastructural expansion microscopy reveals unexpected levels of glycosome heterogeneity in African trypanosomes

Journal of Microscopy, EarlyView.
Abstract Kinetoplastid parasites include several species. Trypanosoma brucei causes African sleeping sickness in humans and a wasting disease nagana in livestock. Trypanosoma cruzi is the causative agent of Chagas disease and Leishmania species cause leishmaniasis, which can present with visceral, cutaneous, or mucocutaneous symptoms.

Glyoxalase I gene deletion mutants of Leishmania donovani exhibit reduced methylglyoxal detoxification. [PDF]

PLoS ONE, 2009
BACKGROUND:Glyoxalase I is a metalloenzyme of the glyoxalase pathway that plays a central role in eliminating the toxic metabolite methyglyoxal. The protozoan parasite Leishmania donovani possesses a unique trypanothione dependent glyoxalase system ...

Carbon Dioxide Assimilation by Leishmania donovani [PDF]

Nature, 1960
WHILE studying the glucose metabolism of Leishmania donovani, the protozoan organism causing visceral leishmaniasis, it has been found that cell suspensions of this organism in a saline-bicarbonate buffer containing glucose can assimilate, a measurable amount of carbon dioxide along with the formation of different acidic end products1.
