Abstract

Background:
The cytotoxic T-lymphocyte antigen-4 (CTLA-4) pathway acts as a negative immune regulator of T cell activation and promotes self-tolerance.

Case:
We report the first case of biopsy-proven central nervous system inflammatory demyelination in the context of primary immunodeficiency and a novel CTLA-4 variant.

Conclusions:
This case has significant implications for the development of novel treatments for autoimmune conditions including Multiple Sclerosis and further emphasises the need for caution with clinical use of CTLA-4 immune checkpoint inhibitors in those with a history of inflammatory demyelination.
