摘要

A common hallmark of several neuropsychiatric conditions is an altered protein homeostasis. In this context, ubiquitination has emerged as one of the most important post-translational modifications, regulating various intracellular processes such as protein degradation, autophagy, protein activation, and protein–protein interactions. Ubiquitination can be reversed by the activity of several deubiquitinating enzymes (DUBs), and it is of utmost importance that both processes remain in balance. Understanding the extent to which this system is involved in specific brain disorders opens up new possibilities for treating a broader spectrum of patients by targeting this central hub. In recent years, the attention to one of those DUBs, called CYLD, has increased sharply, but with relatively little focus on the central nervous system (CNS): 55 results for “CYLD Brain” vs. 895 results for “CYLD” in total (NCBI Pubmed search, 17.01.2025). Thus, we aim to provide a first overview of the new findings from the past decade specifically related to the role of CYLD in the physiology and pathology of the CNS.
