Background

Candida glabrata is a facultative intracellular pathogen.
Understanding its interaction with macrophages is crucial for insights into fungal infections.
THP-1 cell line is commonly used for macrophage differentiation.
In vitro models are essential for studying pathogen-host interactions.

Purpose of Study

To develop a reliable in vitro model for studying Candida glabrata.
To assess the intracellular behavior of the pathogen in human macrophages.
To evaluate macrophage responses to Candida infection.

Methods Used

THP-1 monocytes are differentiated into macrophages using PMA treatment.
Macrophages are infected with Candida glabrata cells.
Non-phagocytosed cells are removed through PBS washes.
Intracellular cells are recovered for further analysis.

Main Results

The protocol allows for the assessment of Candida glabrata virulence in macrophages.
It enables the study of cytokine responses in THP-1 macrophages.
Insights into the maturation processes of macrophages upon infection are provided.

Conclusions

This in vitro model is a valuable tool for studying fungal pathogenesis.
It contributes to the understanding of host-pathogen interactions.
Future studies can leverage this model to explore therapeutic interventions.
