Welcome to the Cilia Group

We study the primary cilium, a surface-exposed sensory organelle that coordinates cellular signaling during development and in tissue homeostasis, and when defective results in numerous diseases and pleiotropic syndromes called ciliopathies that affect most tissues and organs in our body. We employ a variety of different approaches, from biochemistry, molecular biology and proteomics to mammalian cell cultures and zebrafish models, to study the molecular mechanisms by which primary cilia assemble, disassemble, and function to coordinate cellular signaling networks during embryonic development and in tissue homeostasis.

 

 

 

 

 

 

 

Our research proceeds via several tracks to understand how primary cilia organize spatiotemporal signaling networks and in what way perturbation of these networks contributes to health and disease. One direction focuses on characterization of novel ciliary disease genes, and how mutations in these genes lead to congenital heart and brain disorders. A second track is aimed at understanding vesicular trafficking to and from primary cilia, and how defects in these processes are linked to cancer, developmental syndromes and neurodegenerative disorders. Previously, we uncovered a series of new trafficking pathways and molecules that modulate the ability of primary cilia to respond to specific growth factors and morphogens in PDGFRα, TGFβ/BMP and Hedgehog signaling and to adjust the signaling output of receptor activation. These results provide important molecular insight into the etiology of ciliopathies and identify new disease genes linked to ciliary functions.
