Molecular Mechanisms of Promyelocyte Maturation: Implications for Immune Dysfunction in Type II Diabetes

145 p.Thesis (Ph.D.)--University of Illinois at Urbana-Champaign, 2003.The data in this thesis indicate one, that the removal of the tyrosine phosphatase CD45 enhances activation of protein kinase C delta (PKCdelta), and two, PKCdelta activity in conjunction with STAT6 regulate the expression of the co-stimulatory marker B7.2 (CD86) and three, the expression of CD86 and the production of cytokines in phorbol-12-myristate-13-acetate (PMA)-stimulated promyelocytes is regulated by calcium calmodulin kinase kinase alpha. These data together indicate that promyelocyte differentiation is a process that is dependent on the activity of PKCdelta. Furthermore, this process is subject to regulation by interlukin-4 induced STAT6 activation and CaMKKalpha. In conclusion we have identified possible targets for future therapies in the treatment of diabetes induced altered immunity.U of I OnlyRestricted to the U of I community idenfinitely during batch ingest of legacy ETD
