In this study, we demonstrate that stress-activated protein kinases ( SAPK ) are activated after CD40 cross-linking on various B cell lines or human tonsillar B cells .
 ( protein: stress-activated protein kinases, None) , ( cell line: B cell lines, None) , ( cell type: B cells, None) , ( protein: SAPK, None) , ( protein: CD40, None) , ( cell type: human tonsillar B cells, None)
