What is Fas and Fas-L expression in Huntington's disease and Parkinson's disease about?

The Fas/Fas‐L signalling system plays a role in the control of cell death and the survival of lymphocytes, in the regulation of the immune system, and in the progression of autoimmune diseases. Studies in the nervous system have shown Fas/Fas‐L activation in multiple sclerosis and in various paradigms leading to neuronal death. Enhanced Fas and Fas‐L expression has also been documented in astrocytomas and glioma cell lines. However, little is known about the possible implication of Fas/Fas‐L signals in primary human neurodegenerative diseases. In an attempt to gain understanding of the mechanisms commanding cell death and neurone loss in Huntington's disease (HD) and Parkinson's disease (PD), Fas and Fas‐L expression has been examined in the brains of patients with HD and PD with Western blotting and immunohistochemistry. Fas and Fas‐L expression levels are reduced in the caudate and putamen, but not in the parietal cortex, in HD, as revealed in Western blots. Moreover, Fas and Fas‐L immunoreactivity is reduced in striatal neurones in HD. Fas and Fas‐L immunoreactivity is also decreased in neurones of the substantia nigra pars compacta in PD. Reduced Fas and Fas‐L expression is obs
