Adaptation to the host

The pathogenicity of the yeast Candida albicans is associated with adhesion, filamentation, invasion, and toxin production. Nevertheless most clinical isolates and other Candida species, such as C. glabrata, cause infections but often without hyphal formation or being highly damaging in in vitro models.

During infection, Candida species exchange their commensal niche, the intestine, to the bloodstream. This exchange of a commensal environment to an environment where C. albicans causes systemic disease is paired with a sudden exposure to host serum proteins and the inflammatory response. Similarly, C. albicans can cause infections at mucosal surfaces, which are associated with changes in physiology and particularly initiation of inflammation. We hypothesized that specific host factors may drive fungal adaptations to cope with the host immune system.

The research group, therefore, studies how the encounter of host immune mediators and serum proteins drives fungal adaptations that permit survival in the host and immune evasion or escape.
