Inoculation of the Leishmania infantum HSP70-II Null Mutant Induces Long-Term Protection against L. amazonensis Infection in BALB/c Mice

Microorganisms, 2021
Leishmania amazonensis parasites are etiological agents of cutaneous leishmaniasis in the New World. BALB/c mice are highly susceptible to L. amazonensis challenge due to their inability to mount parasite-dependent IFN-γ-mediated responses.

Synthesis, Anti‐Leishmania amazonensis Activity, Cytotoxicity, and Molecular Docking of Anthranilate–Naphthoquinone Hybrids

ChemistrySelect, Volume 11, Issue 40, 27 October 2026.
New anthranilate–naphthoquinone hybrids display potent inhibition of Leishmania (L.) amazonensis with low host cell toxicity. Molecular docking reveals key interactions with TR, GP63, and PTR1, suggesting a multitarget mechanism that contributes to parasite death.

Therapeutic Effects of Matricaria chamomilla Extract in an Immunosuppressed Mouse Model of Cryptosporidiosis

Veterinary Medicine and Science, Volume 12, Issue 5, September 2026.
Chamomile (Matricaria chamomilla) extract significantly reduced oocyst shedding and intestinal lesions in immunosuppressed mice infected with Cryptosporidium parvum, while enhancing antioxidant defences (GPx, TAC). These findings suggest chamomile as a promising phytotherapeutic agent for cryptosporidiosis. ABSTRACT Background Cryptosporidiosis, caused

In vitro and in vivo activity of a palladacycle complex on Leishmania (Leishmania) amazonensis. [PDF]

PLoS Neglected Tropical Diseases, 2012
BACKGROUND: Antitumor cyclopalladated complexes with low toxicity to laboratory animals have shown leishmanicidal effect. These findings stimulated us to test the leishmanicidal property of one palladacycle compound called DPPE 1.2 on Leishmania ...

Proteomic Analysis Reveals a Predominant NFE2L2 (NRF2) Signature in Canonical Pathway and Upstream Regulator Analysis of Leishmania-Infected Macrophages

Frontiers in Immunology, 2019
CBA mice macrophages (MØ) control infection by Leishmania major and are susceptive to Leishmania amazonensis, suggesting that both parasite species induce distinct responses that play important roles in infection outcome.

Evaluation of Uliginosin B as a Modulator of the Ras Pathway: In Vivo Evidence From Caenorhabditis elegans and In Silico Insights

Chemistry &Biodiversity, Volume 23, Issue 8, August 2026.
This study performs in vivo and in silico assays with uliginosin B, targeting its activity in the Ras signaling pathway, demonstrating a possible allosteric interaction with the HRAS (human) and LET‐60 (nematode) proteins, and a decrease in the overexpression of the let‐60 gene in the nematode C. elegans.
