Human T-cell leukemia virus type 1 (HTLV-1) is associated with a variety of clinical manifestations, including tropical spastic paraparesis or HTLV-1-associated myelopathy (TSP/HAM). Viral detection in the central nervous system (CNS) of TSP/HAM patients demonstrates the ability of HTLV-1 to cross the blood-brain barrier (BBB). To investigate viral entry(More)
We searched for the presence of human T-cell leukemia virus type I (HTLV-I) sequences in central nervous system and muscle lesions of 3 patients with tropical spastic paraparesis/HTLV-I-associated myelopathy (TSP/HAM) and 3 patients with HTLV-I-associated polymyositis. Proviral DNA coding for the Tax protein was found by polymerase chain reaction(More)
Inbred strains of mice vary in their susceptibility to the chronic inflammatory and demyelinating disease caused by Theiler's virus. The severity of this disease depends on the extent of demyelination but also on the occurrence of remyelination. We studied the extent of demyelination and remyelination in mice with different genetic backgrounds. To estimate(More)
Very little is known about the factors that determine the outcome of infection by human T cell leukaemia virus type I (HTLV-I) and the neurotropism of this virus is still a controversial point. In transgenic mice, the HTLV-I LTR is active mainly in the central nervous system (CNS), in parenchyma as well as in ependymal and choroid plexus cells. The latter(More)
The aim of this study was to synthesize and examine possible in vitro antioxidant effects of indole-based melatonin analogue compounds. As a part of our ongoing study nineteen indole hydrazide/hydrazone derivatives were synthesized, characterized and their in vitro antioxidant activity was investigated by three different assays: by evaluating their reducing(More)
We generated several lines of mice transgenic for the lacZ reporter gene under the control of an HTLV-I LTR. Two different LTR were used; one was isolated from a case of Adult T-cell Leukemia (ATL), the other from a case of Tropical Spastic Paraparesis (TSP/HAM). These LTR differed at 18 nucleotide positions. The pattern of expression of the transgene,(More)
