Experimental autoimmune encephalomyelitis (EAE) is an animal model
of human disease multiple sclerosis (MS). Clinical signs of EAE are result of
an autoaggressive T-cell response against myelin. We have previously
shown that combined treatment with nucleoside analogues (ribavirin — R
+tiazofurin — T), inosine monophosphate dehydrogenase inhibitors,
ameliorates clinical signs and histological lesions of EAE in susceptible
rats, when they are given preventatively. The aim of this study was to
investigate the effect of combined treatment with R+T, given with the
appearance of first EAE clinical sign, on microglia and astrocytes response.
These cells of the target tissue also participate in an autoimmune process.
The disease was induced in Dark Agouti rats with rat spinal cord
homogenate and had acute monophasic course. Ribavirin and tiazofurin
were given at a dosage of 30 mg/kg/day and 10 mg/kg every other day, for
15 days, respectively. Control group was immunized and treated with saline.
Amelioration of clinical signs and faster recovery was shown in group
treated with combination of R and T in comparison to control group.
Immunohistochemical analysis of the spinal cord tissue isolated after
15 days of combined therapy revealed decrease in vimentin positive cells
and microglia compared to control group. Additionally, morphology of
GFAP positive (glial fibrillary acid protein) cells and microglia indicated to
reactive type of these cells in control group. Results of this study revealed that R and T modulate glial response and have EAE protective effects when
they are given from the onset of disease.
