Abstract
Connective tissue growth factor (CTGF) is a secreted protein involved in a variety of cellular events such as survival, proliferation, and extracellular matrix production. Recent studies suggest a role for this protein also in the repair processes of the central nervous system. The distribution and significance of CTGF in human brain is, however, poorly understood, particularly under pathological conditions. In the present study the expression of CTGF protein was investigated in the spinal cord of control and both sporadic and familial amyotrophic lateral sclerosis (sALS and fALS) patients. Western blot analysis showed a consistent increase in CTGF expression in six sALS patients compared with controls. Immunoreactivity signal for CTGF was equally present in blood vessels of control and ALS spinal cord, but was dramatically increased in reactive astrocytes of the ventral horn and white matter in both sALS and fALS. Increased expression was also observed in the cytoplasm of motor neurons of sALS and fALS patients with long duration of the disease. Our data indicate a role for CTGF in the complex reactive process that is associated with the progression of ALS spinal cord damage. The up-regulation in reactive astrocytes supports a role for CTGF in the molecular mechanisms underlying astrogliosis. However, the altered CTGF expression observed in neurons might represent an additional mechanism involved in motor neuron dysfunction and changes in glial-neuronal communication in the course of the neurodegenerative process.
