immune system
increased B cell apoptosis ( J:208904 )
• 20-fold 7 days after tamoxifen-treatment
increased B cell proliferation ( J:208904 )
• in tamoxifen-treated mice
• however, LPS-induced proliferation is normal and treatment with Syk-specific inhibitor R406 abolishes proliferation
enlarged spleen ( J:208904 )
• 3 and 7 days after tamoxifen treatment
• however, spleen size is restored by 14 days post-induction
abnormal plasma cell differentiation ( J:208904 )
• B cells from tamoxifen-treated mice undergo terminal differentiation into short-lived B cells
increased B cell number ( J:208904 )
• CD19+ B cells in tamoxifen-treated mice
• however, the increased numbers is followed by a decrease
increased IgM level ( J:208904 )
• 20-fold 7 days after tamoxifen-treatment
abnormal circulating chemokine level ( J:208904 )
• increased serum levels of monocyte chemoattractant protein-1, peaking at days 3 to 5 after tamoxifen-treatment
increased circulating interferon-gamma level ( J:208904 )
• peaking at days 3 to 5 after tamoxifen-treatment
increased circulating interleukin-10 level ( J:208904 )
• peaking at days 3 to 5 after tamoxifen-treatment
increased circulating interleukin-6 level ( J:208904 )
