title: [Restoration of the sensitivity of cells resistant to Coxsackie B3 virus after treatment with sensitive cell filtrate].
abstract: The study was done with J-96 cell line sensitive to Coxsackie B3 virus and the subline J-41 derived from it and resistant to this virus. In order to determine the substrates responsible for the susceptibility or resistance of these cells to Coxsackie B3 virus, homogenates and filtrates of the susceptible cells were inoculated into resistant ones and vice versa. Inoculation of the resistant cell homogenates into the susceptible cells at various intervals after virus inoculation did not inhibit virus development. Inoculation of a filtrate of the susceptible cells into resistant ones followed by long-term cultivation resulted in restoration of the susceptibility. Reversion of susceptibility to Coxsackie B3 virus was gradual and accompanied by restoration in the cells of positive Homari test to alkaline phosphatase. The positive result was obtained twice in the absence of reversion in control cells not treated with the filtrate.
