| Research Abstract |
We have developed a live attenuated HSV-1 vector, βH1, expressing β-galactosidase (β-gal) in the nervous system. Its subcutaneous inoculation led the expression of β-gal activity in neurons of the sensory ganglia innervating the inoculation site for at least 45 days. βH1 was also sufficient to deliver the foreign gene into motor neurons in the bilateral anterior horn of the spinal cord of rats by an intramuscular inoculation and β-gal expression continued for at least 182 days in 90% of motor neurons in the bilateral anterior horn of spinal cord in a wide range. The presence of immunity to HSV was not an obstacle to deliver the transgene in anterior horn motor neurons in the intramuscularly inoculated rats. Furthermore, βH1 inoculation into the right caudate putamen of rats was efficient in expressing β-gal activity not only in the neurons of the inoculation site but also in the area projecting to the inoculation site, where this spread of area was regulated by an anti-HSV agent, ganciclovir. βH1 is originated from HSV-1 HF strain that is attenuated to mice, and expresses β-gal activity in the central nervous system (CNS), especially motor neurons in spinal cord without causing tissue destruction or inflammation. It would be a broad potential vector for gene therapy for familial amyotrophic lateral sclerosis and CNS diseases
