Developing giant plasma membrane vesicles from Leishmania cells to investigate the role of membrane proteins in photodynamic inactivation

Photochemistry and Photobiology, EarlyView.
In this study, we developed giant plasma membrane vesicles (GPMVs) from Leishmania amazonensis promastigote membranes to investigate the role of protein‐embedded membranes in methylene blue (MB) photooxidation. Upon MB photoactivation in model lipid membranes (giant unilamellar vesicles, GUVs), a distinct photooxidation effect was observed, marked by ...

Evaluation of the Cutaneous Immunological Milieu Before and After Treatment With Meglumine Antimoniate in Dogs Naturally Affected by Leishmaniosis due to Leishmania infantum

Veterinary Dermatology, EarlyView.
Background: Canine leishmaniosis (CanL) is a zoonotic disease of variable severity. The typical immune response is driven by an exaggerated humoral immune response. Protective immunity is mediated by pro‐inflammatory cytokines that enhance macrophage leishmanicidal activity. Objective: To evaluate the cutaneous and the systemic immune responses as well

Altered miRNA expression in the lesions of cutaneous leishmaniasis caused by L. major and L. tropica with insights into apoptosis regulation

Scientific Reports
Leishmaniasis is a vector-borne infectious disease that affects many subtropical countries. Leishmania (L.) major and L. tropica are among the old-world causative agents and cause cutaneous leishmaniasis (CL).

Canine Leishmaniasis in Rio de Janeiro, Brazil (2000–2015): Taxonomic Characterisation of Etiological Agents and Geospatial Case Analysis

Zoonoses and Public Health, EarlyView.
ABSTRACT Introduction Canine Leishmaniasis is a vector‐borne zoonotic disease caused by several species of protozoa of the genus Leishmania. In the state of Rio de Janeiro (RJ), Leishmania braziliensis is the most prevalent species causing tegumentary leishmaniasis (TL) and Leishmania infantum is the main causative agent of visceral leishmaniasis (VL).

Factors Associated With the Emergence and Spread of Visceral Leishmaniasis in the State of São Paulo, Brazil

Zoonoses and Public Health, EarlyView.
ABSTRACT Introduction Visceral leishmaniasis (VL), once considered a rural disease in Brazil, has progressively urbanised, particularly in the state of São Paulo (SSP), where the first urban cases emerged after the detection of the vector Lutzomyia longipalpis in 1997.

Innate Immunity Plays a Key Role in Leishmania Infection: Implications for Vaccine Design

Journal of Medical Microbiology and Infectious Diseases, 2016
Neutrophils are part of the first line of immune response and are essential for resistance against a variety of pathogens. They professionally mediate direct killing of pathogens, recruit other phagocytes by specific chemokines, produce cytokines and ...

Intralesional gene expression profile of JAK-STAT signaling pathway and associated cytokines in Leishmania tropica-infected patients

Frontiers in Immunology
BackgroundThe JAK-STAT signaling pathway is a central cascade of signal transduction for the myriad of cytokines in which dysregulation has been implicated in progression of inflammatory and infectious diseases.

The role of T cells in sepsis of distinct infectious aetiologies

Clinical and Translational Discovery, Volume 6, Issue 2, April 2026.
Pathogen‐specific sepsis induces mitochondrial dysfunction in T cells, leading to functional alterations. Single‐cell transcriptomics reveals subtype‐specific impairments involving reactive oxygen species accumulation, mtDNA damage, calcium dysregulation, and metabolic reprogramming.
