We investigated the MAPk kinase ( MKK ) that activates p38 MAPk in response to LPS , the p38 MAPk isoforms that are activated as part of this pathway, and the functional responses affected by p38 MAPk activation .
 ( protein: p38 MAPk isoforms, None) , ( protein: p38 MAPk, None) , ( protein: p38 MAPk, None) , ( protein: MKK, None) , ( protein: p38 MAPk, None) , ( protein: MAPk kinase, None)
