Human recombinant myeloperoxidase antiviral activity on cytomegalovirus.

In vitro incubation of human cytomegalovirus (Towne strain) with 8 U/ml human recombinant myeloperoxidase plus sodium chloride and glucose nearly abolished viral infectivity. To assay the effect on intracellular infection, cell toxicity of the enzymes was first studied. Even the high dose of 16 U/ml of recombinant myeloperoxidase plus 10 mU/ml glucose oxidase did not decrease MRC5 cell growth.

Generation of immature autologous clinical grade dendritic cells for vaccination of cancer patients.

Background: Dendritic cell (DC)-based vaccine is a promising approach for cancer therapy. Pioneer trials have been conducted using DC generated in research conditions. There is now a need for generating DC in clinical grade conditions, including the use of closed systems, avoidance of FCS and respect of good manufacturing practices (GMP).
