Molecular Phylogenetic Analysis of Paracoccidioides Species Complex Present in Paracoccidioidomycosis Patient Tissue Samples

Microorganisms, 2023
Paracoccidioidomycosis (PCM) is the main and most prevalent systemic mycosis in Latin America, that until recently, it was believed to be caused only by Paracoccidioides brasiliensis (P. brasiliensis). In 2006, researchers described three cryptic species:

The Syk-Coupled C-Type Lectin Receptors Dectin-2 and Dectin-3 Are Involved in Paracoccidioides brasiliensis Recognition by Human Plasmacytoid Dendritic Cells

Frontiers in Immunology, 2018
Plasmacytoid dendritic cells (pDCs), which have been extensively studied in the context of the immune response to viruses, have recently been implicated in host defense mechanisms against fungal infections.

THE POWER OF THE SMALL: THE EXAMPLE OF Paracoccidioides brasiliensis CONIDIA [PDF]

Revista do Instituto de Medicina Tropical de São Paulo, 2015
SUMMARYResearch on Paracoccidioides brasiliensis has centered in the yeast cell probably because of the lack of distinctive features in the mycelium. In 1942 and for the first time, lateral conidia were noticed in the fungus' hyphae. Later on, Brazilian, Venezuelan and Argentinean researchers described "aleurias" when the fungus was grown in natural ...

Integrated In Silico – In Vitro Study Investigating Dipeptides as Chorismate Synthase Modulators: Spotlight on Its Mechanism of Action

Global Challenges, Volume 9, Issue 12, December 2025.
This study integrates computational and experimental approaches to explore how short dipeptides modulate the activity of chorismate synthase. Unexpectedly, the GluAsp dipeptide enhanced enzyme activity by promoting a transient surface channel near the active site, possibly revealing a new structural feature relevant for microbial metabolism and ...

Flagellins as Vaccine Adjuvants and Cancer Immunotherapy: Recent Advances and Future Prospects

Immunology, Volume 176, Issue 3, Page 277-303, November 2025.
The figure depicts the role of flagellin in immune cells. Flagellin interacts with TLR5, resulting in the formation of homodimers and the recruitment of MyD88, which activates the IκB and MAPK signalling pathways. This results in the activation of NF‐κB and AP‐1, producing TNF‐α, IL‐6, IL‐8, and IL‐12.

Importance of xenarthrans in the eco-epidemiology of Paracoccidioides brasiliensis [PDF]

BMC Research Notes, 2009
Several pathogens that cause important zoonotic diseases have been frequently associated with armadillos and other xenarthrans. This mammal group typically has evolved on the South American continent and many of its extant species are seriously threatened with extinction.

Extracellular Vesicles From Fungal Infection in Humans: A Key Player in Immunological Responses

Journal of Extracellular Biology, Volume 4, Issue 8, August 2025.
ABSTRACT Fungal infections cause approximately 1.6 million deaths annually. Diagnosing and treating fungal infections is difficult due to limited access to diagnostic tests and rising antifungal resistance. Extracellular vesicles (EVs) facilitate interactions between fungal cells and hosts, significantly influencing the pathogen‐host relationship ...
