Autonome Parvoviren
… gene expression. For this purpose, the cDNA array technique was used. It was previously shown that parvovirus H1 infection leads to the activation of caspase 3 and apoptotic cell death of the human monocytic U937 cell, in a way similar to the apoptotic cell death induced by TNFα. Moreover, …
