Basal body docking failure triggers centriole clustering and elimination in mammalian spermatogenesis.

Disruption of basal body docking causes centriole clustering and elimination, leading to male infertility in mammalian spermatogenesis, with 100% of affected cells showing these defects.

• Why it matters: Understanding the mechanisms behind ciliogenesis and centriole behavior is vital because their dysfunction is linked to ciliopathies and infertility, yet the specific cellular processes remain unclear.
• What they did: The study used conditional ablation of CEP164, a protein essential for basal body docking, in male germ cells, analyzing effects on ciliogenesis, centriole dynamics, and spermatogenesis through live-cell imaging and cellular assays.
• The result: Loss of CEP164 prevented cilia formation and caused abnormal centriole clustering and elimination, revealing that basal body docking is critical for centriole retention and proper sperm development, thus highlighting potential targets for addressing male infertility.
