Onward from the cradle

Research output: Contribution to journalReview articlepeer-review


This essay records a voyage of discovery from the "cradle of cell biology" to the present, focused on the biology of the oldest known cell organelle, the cilium. In the "romper room" of cilia and microtubule (MT) biology, the sliding MT hypothesis of ciliary motility was born. From the "summer of love," students and colleagues joined the journey to test switch-point mechanisms of motility. In the new century, interest in nonmotile (primary) cilia, never lost from the cradle, was rekindled, leading to discoveries relating ciliogenesis to autophagy and hypotheses of how molecules cross ciliary necklace barriers for cell signaling.
