Does betulinic acid synergically enhance BMP2-induced bone formation via stimulating Smad 1/5/8 and p38 pathways?
BetA can enhance in vivo osteogenic potentials of BMP2, possibly via stimulating Smad 1/5/8 and p38 pathways, and combination of both agents can be considered as a therapeutic strategy for bone diseases.
This study defines the T lymphocytes that infiltrate NPs as memory T cells in an activated status, with homing properties related to the mucosal immune system. They are resistant to anti-CD95-mediated apoptosis and produced a mixed TH1 /TH2 cytokine pattern as defined by the simultaneous production of IFN-gamma and IL-5.
