The Regulatory Effect of Histone Deacetylase (HDAC) 1 and 2 on iNOS, IL‐6, TNF‐α and IL‐10 Expression in Canine Macrophages Infected With Leishmania infantum

Parasite Immunology, Volume 48, Issue 4, April 2026.
ABSTRACT Zoonotic visceral leishmaniasis is caused by Leishmania (Leishmania) infantum. Dogs are considered the most critical urban reservoirs of L. (L.) infantum due to their high infection rate and direct transmission to humans. The parasite has developed mechanisms to evade the host's defence system by inhibiting macrophage activation, thereby ...

Proteophosophoglycans regurgitated by Leishmania-infected sand flies target the L-arginine metabolism of host macrophages to promote parasite survival [PDF]

, 2009
All natural Leishmania infections start in the skin; however, little is known of the contribution made by the sand fly vector to the earliest events in mammalian infection, especially in inflamed skin that can rapidly kill invading parasites.

Unveiling the Leishmanicidal Mechanism of 4‐Nerolidylcatechol Isolated From Piper peltatum Against Leishmania infantum

Chemistry &Biodiversity, Volume 23, Issue 1, January 2026.
ABSTRACT The present study assessed the leishmanicidal activity of 4‐nerolidylcatechol (4‐NC) (1) isolated from Piper peltatum leaves against promastigotes and amastigotes of Leishmania amazonensis, L. braziliensis, and L. infantum. The plant was fractionated, leading to the isolation and chemical identification of 4‐NC (1). Biochemical techniques were

The Lutzomyia longipalpis complex: what's next? [PDF]

Trends Parasitol
Lutzomyia longipalpis is a phlebotomine sand fly of medico-veterinary importance and the primary vector of Leishmania infantum in the Americas. Its taxonomic status has been debated for decades, with ongoing uncertainty about whether it represents a single species or a species complex. While multiple studies support the existence of cryptic species, no
