The Barr lab uses the nematode C. elegans to study fundamental questions in biology (ciliogenesis, ciliary transport, and most recently, ciliary extracellular vesicles) and to model human genetic diseases of cilia. Using the beautiful simplicity of “the worm,” we consistently tackle major important problems that are biomedically relevant, and have a track record of groundbreaking discoveries. Many of the genes and pathways we study control C. elegans behaviors, therefore we are also interested in neurogenetics and neuroplasticity. Our studies have guided research into autosomal polycystic kidney disease and other ciliopathies. Our research has unlocked insights into three exciting new areas in the Barr lab: ciliary specialization, extracellular vesicles (EVs), and stress-induced neuronal restructuring.

We are obsessed about ciliary extracellular vesicles!

Juan and Maureen wrote a review on Ciliary Extracellular Vesicles: Txt Msg Organelles.

See also Juan’s paper on defining the molecular signature of extracellular vesicle releasing neurons in Current Biology. This work was initiated during Maureen’s sabbatical in the lab of Coleen Murphy at Princeton, our collaborators.
