Cd40-Mediated Signaling Of Interleukin-1(Beta) Synthesis And Rescue From Apoptosis In Monocytes: Modulation By Il-4 And Il-10, Jonathan C. Poe

Electronic Theses and Dissertations

To date, the cellular mechanisms involved in the progression of diseases characterized by chronic inflammation, such as rheumatoid arthritis (RA), remain largely unknown. However, cell-to-cell contact interactions between CD4+ helper T (Th) cells and monocytes have been implicated in the induction and maintenance of pro-inflammatory cytokine synthesis that is characteristic to the pathogenesis of RA. One such cytokine produced during monocyte-Th cell contact is interleukin (IL)-1 β, a mediator directly involved in the characteristic tissue destruction that occurs in the synovia of individuals with RA. Previous studies in our laboratories have shown that ligation of CD40 on monocytes with CD40 …
