Multiplication of Human Natural Killer Cells by Nanosized Phosphonate-Capped Dendrimers

Non‐natural born killers: The addition of phosphorus‐containing dendrimers capped with phosphonate end groups to cultures of human peripheral blood mononuclear cells (white blood cells) strongly stimulates the selective multiplication of functional natural killer (NK) cells (see picture), which play a key role in anticancer immunity. Both the generation of the dendrimer and the type of end groups are important criteria for the activity.
