Given the previously reported involvement of additional ESCRT-III proteins (CHMP4B, CHMP2B, and VPS4) in NPC and NE surveillance and homeostasis [6, 25, 29, 30], we sought to determine whether the nuclear distribution and cellular expression of CHMP4B, CHMP2B, and VPS4 was altered in ALS neuronal nuclei. This evidence concerns the gene VPS4A and amyotrophic lateral sclerosis.
