“…Levels of activated, phosphorylated (p-) PKB are elevated in RA versus non-RA synovial tissue, and PKB-dependent phosphorylation of FoxO4 in synovial macrophages, particularly in the synovial sublining, is significantly enhanced in RA 5 6. Tec family kinases include Tec, Bruton's tyrosine kinase (Btk), Itk, Bmx and Rlk 7. Complete activation of Tec family kinases upon cell-surface receptor triggering requires PI3K-dependent relocalisation of the protein to the plasma membrane, subsequent phosphorylation by a Src family kinase, and finally autophosphorylation 8.…”
