Abstract

Background: The interaction between the host and Candida albicans is dynamic and intricate. We performed proteomic analysis to explore monocyte-C. albicans hyphae interaction. Materials & methods: Primary human monocytes were stimulated by heat-killed C. albicans hyphae and their proteins were profiled by tandem liquid chromatography with mass spectrometry (LC-MS/MS). Results: Based on the protein database of different species for analysis, we found that stimulation of monocytes by hyphae was accompanied by upregulation of histones and activation of extracellular traps (ETs) formation pathway. Meanwhile, monocyte ETs (MoETs) were evoked by synthesis or alteration of C. albicans cell wall proteins expression during the morphological switch to hyphal. Conclusion: MoETs formation is linked to cell wall proteins of C. albicans hyphae.
