Special Issue: Cilia and Flagella: from Basic Biology to Disease
RESEARCH ARTICLES
A novel approach to tagging tubulin reveals microtubule assembly dynamics of the axoneme in Trypanosoma brucei
Summary: The grow-and-lock model with a twist: cell cycle-dependent regulation of tubulin addition in the Trypanosoma brucei flagellum.
SAXO proteins mediate tubulin turnover in axonemal microtubules of Chlamydomonas
Summary: SAXO proteins stabilize axonemal microtubules by reducing tubulin turnover to regulate ciliary length and assembly, without affecting ciliary motility.
Skeletal ciliopathy variants of the dynein-2 DYNC2LI1 subunit impair osteogenic differentiation of mesenchymal stem cells
Summary: Skeletal ciliopathy variants of the dynein-2 subunit DYNC2LI1 impair osteogenic differentiation of mesenchymal stem cells owing to defects in retrograde ciliary protein trafficking, resulting in defects in Hedgehog signaling.
β-Arrestin mediates the export of ciliary GPR161 but not Smoothened together with the BBSome and intraflagellar transport machinery
Summary: β-Arrestin plays crucial roles in the export of ciliary GPCRs. By connecting the BBSome and GPR161, β-arrestin mediates the export of GPR161 from cilia upon Hedgehog signaling activation.
Primary cilia shape postnatal astrocyte development through Sonic Hedgehog signaling
Summary: Cilia play a direct role in regulating the Sonic hedgehog pathway in developing astrocytes, revealing novel functions for ciliary signaling during astrocyte proliferation and morphological development.
Phosphorylation-induced SUMOylation promotes Ulk4 condensation at the ciliary tip to transduce Hedgehog signal
Summary: In response to Shh stimulation, Ulk4 undergoes phosphorylation-dependent SUMOylation, which promotes its condensation at ciliary tip to transduce Shh signal.

Origin and evolution of mitochondrial inner membrane composition

In this Review, Kailash Venkatraman and colleagues provide an examination of the morphological similarities between prokaryotic intracytoplasmic membranes and mitochondrial inner membranes, and whether cristae evolution has driven specialisation of the mitochondrial lipidome.
Resolution in super-resolution microscopy
Super-resolution microscopy (SRM) has emerged as a powerful tool for biological discovery. In this Perspective, Kirti Prakash and colleagues compile expert opinions on crucial, yet often overlooked, aspects of SRM that are essential for maximising its benefits and advancing the field.
