Innate Resistance to Leishmania amazonensis Infection in Rat Is Dependent on NOS2

Frontiers in Microbiology, 2021
Leishmania infection causes diverse clinical manifestations in humans. The disease outcome is complicated by the combination of many host and parasite factors.

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. [PDF]

Parasite Immunol
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 ...

Experimental infection and transmission of Leishmania by Lutzomyia cruzi (Diptera: Psychodidae): Aspects of the ecology of parasite-vector interactions. [PDF]

PLoS Neglected Tropical Diseases, 2017
Several parameters should be addressed before incriminating a vector for Leishmania transmission. Those may include its ability to become infected by the same Leishmania species found in humans, the degree of attractiveness for reservoirs and humans and ...

In vitro and in vivo Anti-leishmanial Potential of [Ag (PTA) 4 ]BF 4 and [Ag(HBPz 3 )(PPh 3 )] Silver Complexes

Revista da Sociedade Brasileira de Medicina Tropical, 2022
Background: American tegumentary leishmaniasis is a parasitic disease known for being difficult to treat; therefore, the search for more effective therapeutic methods is necessary.

Experimental model of chronic osteomyelitis caused by Leishmania (L) amazonensis [PDF]

Acta Tropica, 2006
Experimental animal models have been used for the study of the physiopathogenesis of leishmaniasis, on some occasions with success, while in other situations such as bone alterations that accompany tegumentary leishmaniasis, especially in diffuse cutaneous form (DCL), the mechanisms are still unknown.

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.

DH82 Canine and RAW264.7 Murine Macrophage Cell Lines Display Distinct Activation Profiles Upon Interaction With Leishmania infantum and Leishmania amazonensis

Frontiers in Cellular and Infection Microbiology, 2020
Leishmaniasis is an anthropozoonotic disease, and dogs are considered the main urban reservoir of the parasite. Macrophages, the target cells of Leishmania sp., play an important role during infection.

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.

The Expression of Mannose Receptors in Skin Fibroblast and Their Involvement in Leishmania (L.) amazonensis Invasion [PDF]

Journal of Histochemistry & Cytochemistry, 2005
Leishmania are protozoa that invade mononuclear phagocytes with the involvement of different ligand-receptor systems, including mannose receptors. Until now, scant data are available concerning the mechanisms that govern the infection of Leishmania in other host cell types such as fibroblasts. Our aim was to analyze the expression of mannose receptors

Immunization with antigenic extracts of Leishmania associated with Montanide ISA 763 adjuvant induces partial protection in BALB/c mice against Leishmania (Leishmania) amazonensis infection [PDF]

, 2014
Background/Purpose: A proper adjuvant has a relevant role in vaccine formulations to generate an effective immune response. In this study, total Leishmania antigen (TLA) formulated with Montanide ISA 763 or R848 as adjuvants were evaluated as a first ...
