Amyotrophic lateral sclerosis: thyrotropin-releasing hormone and histidyl proline diketopiperazine in the spinal cord and cerebrospinal fluid.

Abstract:

:In spinal cords from seven amyotrophic lateral sclerosis (ALS) patients and four controls, we found no difference in thyrotropin-releasing hormone (TRH) concentration relative to protein content, but there was a reduction per tissue wet weight in ALS. Immunohistochemical localization of TRH in ALS cord was unaltered. Histidyl proline diketopiperazine (HisPro-DKP), a possible metabolite of TRH, was significantly elevated per protein content in ALS. CSF levels of TRH and HisPro-DKP were unchanged. These findings suggest that TRH neurons are not primarily affected in ALS, but TRH and tissue protein are lost together as the disease progresses.
