Treatment of Plaque Infections and Periodontitis using Stem Cells- A New Prospect
Poster Jan 30, 2009
Dental precursor cells are attractive for novel approaches to treat diseases like periodontitis, dental caries or to improve dental pulp healing and the regeneration of craniofacial bone and teeth. These cells are easily accessible and, in contrast to bone-marrow-derived mesenchymal stem cells, are more closely related to dental tissues. This paper gives a short overview of stem cells of dental origin.
The nuclear receptors pregnane X receptor (PXR) and constitutive androstane receptor (CAR) are closely related transcription factors that regulate the expression of phase I (cytochrome P450s), phase II metabolizing enzymes and transporter genes in response to xenobiotics, including prescription drugs.READ MORE
We found a distinct subpopulation of Tregs within BMSCs. Tregs and BMSCs in co-culture conferred neuroprotection that varied in a dose-dependent manner. Tregs minimized stem cell production of IL-6, a pro-inflammatory cytokine, and inhibited BMSC secretion of FGF-beta, a cytokine related to BMSC proliferation and differentiation. The ratio of Tregs found natively in BMSCs is optimally adapted to provide the maximum neuroprotective benefit of stem cell treatment after ischemic stroke.READ MORE
Patients with partial deficiency of recombination-activating genes 1 or 2 (RAG1/2) can present with a wide spectrum of primary immunodeficiencies including combined immunodeficiency with granuloma and/or autoimmunity (CID-G/AI). Prior case reports have highlighted alterations in B and T cell compartments; however comprehensive characterization of these cell populations with focus on autoreactive-prone subsets has not been reported.READ MORE
