Pharmacological inhibition of key metabolic pathways attenuates Leishmania spp infection in macrophages.

Macrophages represent a fundamental component of the innate immune system that play a critical role in detecting and responding to pathogens as well as danger signals. Leishmania spp. infections lead to a notable alteration in macrophage metabolism, whereby infected cells display heightened energy metabolism that is linked to the integrity of host mitochondria.

Activation Pathways of Murine Macrophages by Lipophosphoglycan from Strains of (FV1 and LV39).

Lipophosphoglycan (LPG) is an important virulence factor. It is the most abundant surface glycoconjugate in promastigotes, playing an important role in the interaction with phagocytic cells. While LPG is known to modulate the macrophage immune response during infection, the activation mechanisms triggered by this glycoconjugate have not been fully elucidated.

Intraperitoneal Administration of 17-DMAG as an Effective Treatment against Infection in BALB/c Mice: A Preclinical Study.

Background: Leishmaniasis is a significant global public health issue that is caused by parasites from genus. With limited treatment options and rising drug resistance, there is a pressing need for new therapeutic approaches. Molecular chaperones, particularly Hsp90, play a crucial role in parasite biology and are emerging as promising targets for drug development.

Identification of Lutzomyia longipalpis' using MALDI-TOF peptide/protein profiles.

Sand flies are vectors of great public health importance, since they constitute a group of hematophagous insects responsible for etiological agents transmission of zoonotic diseases such a visceral leishmaniasis. In face of the expansion of these diseases, efficient control strategies are needed which depend on comprehending the sand fly eco-epidemiology. In this regard, MALDI-TOF mass spectrometry has been used for bacteria, fungi and yeast detection studies through peptide/protein profiles.
