Leishmania infection activates host mTOR for its survival by M2 macrophage polarization.

TL;DR: It is observed that inhibition of M2 macrophage polarization reduced Leishmania survival inside macrophages, suggesting that mTOR plays a crucial role in regulation of M1 macrophAGE polarization and direct the innate immune homeostasis towards parasite survival inside host.
Journal ArticleDOI

Deprivation of L-Arginine Induces Oxidative Stress Mediated Apoptosis in Leishmania donovani Promastigotes: Contribution of the Polyamine Pathway

TL;DR: The growth and survival of Leishmania depends on the availability of extracellular L-arginine, and in its absence the parasite undergoes ROS mediated, caspase-independent apoptosis-like cell death, therefore, L- arginine metabolism pathway could be a probable target for controlling the growth ofLeishmania parasites and disease pathogenesis.
Journal ArticleDOI

Leishmania donovani Activates Hypoxia Inducible Factor-1α and miR-210 for Survival in Macrophages by Downregulation of NF-κB Mediated Pro-inflammatory Immune Response.

TL;DR: Findings suggested that L. donovani infection induces hypoxic environment inside the macrophages that activates HIF-1α, which upregulates miR-210, which eventually establishes a suitable environment for the survival of parasite inside the host macrophage by downregulating NF-κB mediated pro-inflammatory immune responses.
Journal ArticleDOI

l-Arginine Uptake by Cationic Amino Acid Transporter Promotes Intra-Macrophage Survival of Leishmania donovani by Enhancing Arginase-Mediated Polyamine Synthesis.

TL;DR: It is demonstrated that intra-macrophage survival of L. donovani depends on the availability of extracellular l-arginine, and the involvement of the transporters is observed, providing clear evidence for targeting the metabolism of l- arginine and l- Arginine-metabolizing enzymes as an important therapeutic and prophylactic strategy to treat VL.
