Effect of PI3K inhibitors on anti-IgM-induced B-cell proliferation. Primary splenic B cells were cultured with anti-IgM in presence or in absence of the indicated doses of PI3K inhibitors, followed by measurement of [3H]-thymidine incorporation after 48 hours. Results were expressed as percentage of control response of cells that were not treated with PI3K inhibitors. Error bars indicate SD.
