Nipah@20: Lessons Learned from Another Virus with Pandemic Potential.

abstract：:The fungal pathogen Candida glabrata can cause both mucosal and disseminated infections. Cell adhesion, a key step in colonization and infection, depends in C. glabrata primarily on the Epa family of cell adhesion proteins. While Epa proteins have been documented to mediate specific adhesion to host glycans, some of t...
