Scientists at the University of Alberta have found that some T-cells, which could be used in therapies combating MS, can kill neurons.
According to the study, published in the Journal of Leukocyte Biology, this means that more research must be carried out on the cells before they are involved in any MS treatments.
Dr Fabrizio Giuliani said: "We were looking at how a specific type of T-cell could prevent neuronal death and then we found out they were doing the killing."
This comes after a study published in Nature Immunology discovered a molecule that plays a major role in autoimmune diseases such as MS.
Researchers from Thomas Jefferson University believe that by finding a way to block the GM-CSF molecule, they could access new treatments for the condition.
