From: The modulation of immunological activities in human NK cells by extracts of ginkgo
Effect of ginkgo on NK cell surface markers using a fluorescence-activated cell sorter, FACScalibur. Data are presented as the mean ± SD (n = 3). The expression of CD56 (NK cell surface marker) was elevated and the expression of CD19 had dropped after day 14 of ginkgo ingestion. The t test was used to analyze the expression of each surface marker, with the significance set at p < 0.05
