Structural basis of secreted acid phosphatase polymerization in the Leishmania parasite

Protein 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 ...

Immunogold labeling and cerium cytochemistry of the enzyme ecto-5'-nucleotidase in promastigote forms of Leishmania species

Memorias do Instituto Oswaldo Cruz, 1993
We have applied both enzyme cytochemistry and immunological labeling techniques to characterize the enzyme 5'-nucleotidase (5'-Nase), at the ultrastructural level, in promastigote forms of four Leishmania species: Leishmania amazonensis, Leishmania ...

Nano‐Encapsulated Cinnamomum cassia Essential Oil in Combination With Fluconazole Exhibits Synergistic Activity Against Fluconazole‐Resistant Nakaseomyces glabratus and Pichia kudriavzevii

Veterinary Medicine and Science, Volume 12, Issue 3, May 2026.
Nano‐encapsulated Cinnamomum cassia essential oil (nano‐CC‐EO) showed in vitro antifungal activity against fluconazole‐resistant Nakaseomyces glabratus and Pichia kudriavzevii clinical isolates. Checkerboard assays revealed synergistic or additive interactions between nano‐CC‐EO and fluconazole in several isolates, without evidence of antagonism. These

Tegumentary Leishmaniasis Associated With Immune Reconstitution in an HIV Patient—A Case Report

Parasite Immunology, Volume 48, Issue 5, May 2026.
ABSTRACT HIV‐associated Immune Reconstitution Inflammatory Syndrome (IRIS) may significantly alter the immunopathological presentation of American Tegumentary Leishmaniasis (ATL), occasionally causing paradoxical clinical exacerbations. We report the long‐term follow‐up of a 39‐year‐old female coinfected with HIV and disseminated mucocutaneous ...

Exploring the Role of the MAPK Signalling Pathway in Dog Immunity: From Cancer to Parasitic Diseases

Parasite Immunology, Volume 48, Issue 5, May 2026.
ABSTRACT Mitogen‐activated protein kinases (MAPKs) are intracellular signalling proteins that modulate several cellular processes, such as proliferation, cytokine production and survival. Like humans, dogs may exhibit changes in MAPK signalling under pathological conditions.

Comparative two-dimensional gel electrophoresis maps for promastigotes of Leishmania amazonensis and Leishmania major

Brazilian Journal of Infectious Diseases
The outcome of Leishmania infections is determined by both the parasite species and the host genetic makeup. While much has been learned regarding immune responses to this parasite, our knowledge on parasite-derived factors is limited.
