Primary cilia are sensory organelles present in many cell types, partaking in various signaling processes. Primary cilia of pancreatic beta cells play pivotal roles in paracrine signaling and their ...

The central apparatus (CA) within the sperm axoneme is vital for sperm motility, yet its molecular architecture and functional mechanisms remain incompletely understood. Combining cryo-electron ...

A 3D rendering showing the internal structure of an animal cell, with several round or wavy structures inside a border. It turns out that the redox state of a cell, such as the animal cell shown, is ...
