Pathophysiology
When infected by HTLV-1[1] the host mounts an antigen specific immune response towards the HTLV-1 antigen. Cytotoxic T-lymphocytes of the host’s immune response release cytokines in an effort to fight the infection. These cytokines facilitate the transendothelial migration of lymphocytes across the blood-brain barrier. Once cytokines are within the central nervous system demyelination is brought as a result of bystander cell injury. The disease is chronic, progressing slowly, usually causing symptoms 20-30 years after infection.
