Primary cilia and their anchoring basal bodies are important regulators of a growing list of signaling pathways. Consequently, dysfunction in proteins associated with these structures results in perturbation of the development and function of a spectrum of tissue and cell types. Here, we review the role of cilia in mediating the development and function of the pancreas. We focus on ciliary regulation of major pathways involved in pancreatic development, including Shh, Wnt, TGF-β, Notch, and fibroblast growth factor. We also discuss pancreatic phenotypes associated with ciliary dysfunction, including pancreatic cysts and defects in glucose homeostasis, and explore the potential role of cilia in such defects.

Extracellular membrane vesicles (EVs) offer promising values in various medical fields, e.g., as biomarkers in liquid biopsies or as native (or bioengineered) biological nanocarriers in tissue engineering, regenerative medicine and cancer therapy.

Outer dynein arms (ODAs) are essential for ciliary motility and are preassembled in the cytoplasm before trafficking into cilia by intraflagellar transport (IFT). ODA16 is a key adaptor protein that links ODAs to the IFT machinery via a direct interaction with the IFT46 protein. However, the molecular mechanisms regulating the assembly, transport, and release of ODAs remain poorly understood.

Genotype-phenotype correlations of rare diseases are complicated by low patient number, high phenotype variability and compound heterozygosity. Mutations may cause instability of single proteins, and affect protein complex formation or overall robustness of a specific process in a given cell. Ciliopathies offer an interesting case for studying genotype-phenotype correlations as they have a spectrum of severity and include diverse phenotypes depending on different mutations in the same protein.

Snap-through, a rapid transition of a system from an equilibrium state to a nonadjacent equilibrium state, is a valuable design element of soft devices for converting a monolithic stimulus into systematic responses with impulsive motions. A common way to benefit from snap-through is to embody it within structures and materials, such as bistable structures. Torque-reversal mechanisms discovered in nature, which harness snap-through instability via muscular forces, may have comparative advantages.
