Clonal variation within a mucosal isolate derived from a patient with Leishmania (Viannia) braziliensis infection Variação clonal de um isolado derivado de um paciente com infecção mucosa pela Leishmania (Viannia) braziliensis

open access: yesRevista do Instituto de Medicina Tropical de São Paulo, 1991
Three isolates over 5 years from a patient with persistent relapsing mucosal leishmaniasis due to Leishmania (Viannia) braziliensis and 7 clones from one of these isolates were studied by zymodemes and scrodemes analysis.

Sclerosing Orbital Inflammation Caused by Leishmania braziliensis [PDF]

open access: yesThe American Society of Tropical Medicine and Hygiene, 2017
Orbital biopsy of nonspecific orbital inflammation, commonly referred to as “orbital pseudotumor,” typically shows a combination of polyclonal lymphocytes, plasmocytes, leukocytes, macrophages, and variable degrees of collagen deposition. Herein, we report a patient with a positive history of mucocutaneous leishmaniasis who presented with an orbital ...

Thymus and Leishmania at the Crossroads: Autoimmunity and Cancer

open access: yesImmunology, Volume 178, Issue 3, Page 377-386, July 2026.
Conceptual ‘Crossroads Model’ linking Leishmania, thymic infection and immune dysregulation: an integrative model is proposed in which Leishmania infection disrupts thymic architecture and stromal–thymocyte interactions. These alterations converge to promote defective tolerance, increased autoimmune risk and a microenvironment permissive to malignant ...

Leukocyte Behavior in Mesenteric Microcirculation upon Experimental By Leishmania Spp. in BALB/c Mice

open access: yesIranian Journal of Parasitology, 2021
Background: We aimed to determine the cellular recruitment (leukocyte rolling and adhesion) by which the Leishmania (Viannia) braziliensis, L. (Leishmania) amazonensis, and L. (Leishmania) major species in the mesenteric microcirculation of BALB/c mice.

Exploring 6‐Hydroxy‐3‐Aryl/Heteroarylcoumarins as Promising Candidates Against Trypanosoma cruzi

open access: yesChemMedChem, Volume 21, Issue 9, 14 May 2026.
New therapies are urgently needed for Chagas disease, and screening of 6‐hydroxy‐3‐aryl/heteroarylcoumarin derivatives identified highly selective compounds with potent activity against T. cruzi. In particular, derivative 1f showed submicromolar trypomastigote potency, dual‐stage activity, and inhibition of amastigote‐to‐trypomastigote differentiation,

Treatment of canine cutaneous leishmaniasis by Leishmania (Viannia) braziliensis in dogs with furazolidone and β-cyclodextrin: case report.

open access: yesVeterinaria Italiana, 2023
Euthanasia of animals is not accepted as a control for cutaneous leishmaniasis caused by Leishmania (Viannia) braziliensis and drugs used in humans for the treatment of leishmaniasis are not allowed for animals in Brazil.

Structural basis of secreted acid phosphatase polymerization in the Leishmania parasite

open access: yesProtein Science, Volume 35, Issue 5, May 2026.
Abstract Enzymes that assemble into filaments typically transition between protomeric and polymeric states in response to cellular conditions. In contrast, the secreted acid phosphatase (SAP) of Leishmania, one of the most abundant extracellular glycoproteins produced by the parasite and regarded as a major virulence factor in the neglected tropical ...

Peptides as a Therapeutic Alternative Against Leishmaniasis: A Scoping Review

open access: yesChemical Biology &Drug Design, Volume 107, Issue 5, May 2026.
This scoping review of 79 studies identified 231 antimicrobial peptides with anti‐Leishmania activity, including natural‐derived and synthetic peptides (inspired by natural sources or developed through rational design). Most were evaluated in vitro against promastigote and/or amastigote forms, with synthetic peptides showing a more promising effect ...
