The primary cilium is an antenna-like cellular protrusion mediating sensory and neuroendocrine signaling. Its localization within tissue architecture and a growing list of cilia-localized receptors, in particular G-protein-coupled receptors, determine a host of crucial physiologies, which are disrupted in human ciliopathies. Here, we discuss recent advances in the identification and characterization of ciliary signaling components and pathways. Recent studies have highlighted the unique signaling environment of the primary cilium and we are just beginning to understand how this design allows for highly amplified and regulated signaling.

The brain uses a specialized system to transport cerebrospinal fluid (CSF), consisting of interconnected ventricles lined by motile ciliated ependymal cells. These cells act jointly with CSF secretion and cardiac pressure gradients to regulate CSF dynamics. To date, the link between cilia-mediated CSF flow and brain function is poorly understood.

The rapid advancement of tactile electronic skin (E-skin) has highlighted the effectiveness of incorporating bionic, force-sensitive microstructures in order to enhance sensing performance. Among these, cilia-like microstructures with high aspect ratios, whose inspiration is mammalian hair and the lateral line system of fish, have attracted significant attention for their unique ability to enable E-skin to detect weak signals, even in extreme conditions. Herein, this review critically examines recent progress in the development of cilia-inspired bionic tactile E-skin, with a focus on columnar, conical and filiform microstructures, as well as their fabrication strategies, including template-based and template-free methods.

Hedgehog (Hh) morphogen governs embryonic development and tissue homeostasis through the Ci/Gli family transcription factors. Here we report that Hh induces phase separation of the fused (Fu)/Ulk family kinases to allosterically regulate Ci/Gli. We find that Hh-induced phosphorylation of Fu/Ulk3 promotes SUMOylation of their inverted phosphorylation-dependent SUMOylation motifs.

Prostate cancer (PCa) is one of the most common malignancies for male individuals globally. Androgen deprivation therapy (ADT) initially demonstrated significant efficacy in treating PCa; however, most cases of PCa eventually progress to castration-resistant prostate cancer (CRPC), which becomes increasingly challenging to manage. Notably, the loss or disruption of primary cilia in PCa cells may play a critical role in the progression of the disease, and there are no reports on the role of circular RNAs in ciliogenesis.
