In vivo and in vitro models of demyelinating disease: efficiency of virus spread and formation of infectious centers among glial cells is genetically determined by the murine host.

abstract：:Mutants of bacteriophage T4D that are defective in genes 42 (dCMP hydroxymethylase), 46 (DNA exonuclease), and 56 (dCTPase) produce limited amounts of phage DNA in Escherichia coli B. In this DNA, glucoylated 5-hydroxymethylcytosine is completely replaced by cytosine. We found that this DNA rapidly becomes fragmented ...
