Summary

Fungi are engaged in a variety of biotic interactions ranging from symbiosis to pathogenicity. We are interested in the mechanisms governing non-self recognition in this vast branch of the eukaryotic tree.

 

Research Activity

We study various aspects of the detection and response to non-self in fungi with a particular emphasis on a family of cytoplasmic receptors termed NLRs that control innate immunity and other biotic interaction processes in animal and plant lineages.

 

Keywords

Programmed Cell death - Fungal immune response - Functional amyloid - NOD-like receptors - Pore forming protein –fungal-bacterial interactions
