Transcriptome and proteome changes triggered by overexpression of the transcriptional regulator Maf1 in the human pathogen Leishmania major

open access: yesThe FASEB Journal, Volume 38, Issue 16, 31 August 2024.
The transcriptome and proteome changes caused by the overexpression of Maf1 in the protozoan parasite Leishmania major suggest the participation of this protein in multiple key biological processes. Abstract Maf1, originally described as a repressor of RNA polymerase III (RNAP III) transcription in yeast, participates in multiple functions across ...

Environmental Niche Modelling of Phlebotomine Sand Flies and Cutaneous Leishmaniasis Identifies Lutzomyia intermedia as the Main Vector Species in Southeastern Brazil

open access: yesPLoS ONE, 2016
Cutaneous leishmaniasis (CL) is caused by a protozoan of the genus Leishmania and is transmitted by sand flies. The state of Espírito Santo (ES), an endemic area in southeast Brazil, has shown a considerably high prevalence in recent decades ...

Effect of Leishmania infantum infection on B cell lymphopoiesis and memory in the bone marrow and spleen

open access: yesThe FASEB Journal, Volume 38, Issue 16, 31 August 2024.
Visceral leishmaniasis (VL) is not vaccine‐preventable and lethal when left untreated. This study demonstrated that parasites activate and attach to B cells and differentiate into amastigote‐like stages that can be transferred to other host cells. Infection increased B cell progenitors in the bone marrow and all analyzed B cell subsets of the spleen ...
