According to the study, in nearly all ALS patients, a protein called TDP-43 is responsible for forming abnormal clumps within cells, which causes cell death. In recent years, Strong’s team discovered a second protein, called RGNEF, with functions that are opposite to TDP-43.
The team’s research identified a specific fragment of the RGNEF protein -- named NF242 -- that can “mitigate the toxic effects of the ALS-causing protein.”
As a result, the researchers discovered that when the two proteins interact with each other, the toxicity of the ALS-causing protein is removed, which significantly reduces damage to the nerve cell and therefore prevents its death.
