Morphogenesis Dynamics in Leishmania Differentiation

Pathogens, 2022
Leishmania, the causative agent of leishmaniasis, is an obligatory intracellular parasite that cycles between phagolysosome of mammalian macrophages, where it resides as round intracellular amastigotes, and the midgut of female sandflies, where it ...

Exploring Bioactive Metabolites From Fusarium falciforme and Aspergillus terreus Isolated From Protease‐Rich Fruits: Antifungal, Antitrypanosomal, and Enzymatic Inhibitory Activities

Chemistry &Biodiversity, EarlyView.
Metabolites from fungi isolated from protease rich‐fruits displayed antifungal, antitrypanosomal and enzymatic inhibitory activities. ABSTRACT Fungal secondary metabolites display remarkable chemical diversity and biological potential, with applications in agriculture and pharmaceuticals. This study isolated and characterized bioactive metabolites from

Native rodent species are unlikely sources of infection for Leishmania (Viannia) braziliensis along the Transoceanic Highway in Madre de Dios, Peru. [PDF]

, 2014
An estimated 2.3 million disability-adjusted life years are lost globally from leishmaniasis. In Peru's Amazon region, the department of Madre de Dios (MDD) rises above the rest of the country in terms of the annual incidence rates of human leishmaniasis.

Translating Observations From Leishmanization Into Non-Living Vaccines: The Potential of Dendritic Cell-Based Vaccination Strategies Against Leishmania

Frontiers in Immunology, 2018
Leishmaniasis is a health-threatening vector-borne disease in almost 90 different countries. While a prophylactic human vaccine is not yet available, the fact that recovery from leishmaniasis establishes lifelong immunity against secondary infection ...

The Gut Microbiome of the Vector Lutzomyia longipalpis Is Essential for Survival of Leishmania infantum

mBio, 2017
The vector-borne disease leishmaniasis, caused by Leishmania species protozoa, is transmitted to humans by phlebotomine sand flies. Development of Leishmania to infective metacyclic promastigotes in the insect gut, a process termed metacyclogenesis, is ...

Oxidative Stress Modulation and Antileishmanial Activity of Salvinia auriculata

Chemistry &Biodiversity, EarlyView.
Ethanolic extract of Salvinia auriculata showed significant antioxidant and antileishmanial activities. Salviniside II, the major metabolite, was isolated, structurally characterized, and evaluated, but exhibited weaker antiparasitic effects when compared to the whole extract.

Visceral leishmaniasis patients display altered composition and maturity of neutrophils as well as impaired neutrophil effector functions [PDF]

, 2016
Immunologically, active visceral leishmaniasis (VL) is characterised by profound immunosuppression, severe systemic inflammatory responses and an impaired capacity to control parasite replication.

RNA synthesis in Leishmania donovani is constitutive during stage conversion: a genome-wide PRO-seq analysis

Microbiology Spectrum
Transcription in Leishmania donovani has long been considered constitutive, as shown by nuclear run-on analyses and northern blots, with gene expression primarily regulated post-transcriptionally.

Leishmania Genome Dynamics during Environmental Adaptation Reveal Strain-Specific Differences in Gene Copy Number Variation, Karyotype Instability, and Telomeric Amplification

mBio, 2018
Protozoan parasites of the genus Leishmania cause severe human and veterinary diseases worldwide, termed leishmaniases. A hallmark of Leishmania biology is its capacity to adapt to a variety of unpredictable fluctuations inside its human host, notably ...

DPPH‐based Antioxidant Screening and Cellulase‐assisted Hydrodistillation of Matourea azurea: Improved Essential Oil Yield and Density Functional Theory Insights Into a Rare Terpene

Chemistry &Biodiversity, EarlyView.
ABSTRACT Essential oils are rich in bioactive molecules like terpenes and phenolic compounds, but have low yields, making process efficiency crucial. Enzyme‐assisted hydrodistillation is a sustainable alternative, enhancing oil release by degrading the cell wall.
