　View Summary

<p>Interleukin-6 (IL-6) has been demonstrated to play a pivotal role in CNS trauma as a proinflammatory cytokine which regulates inflammatory response. Not only being a mediator of inflammation, but IL-6 induces neural stem/progenitor cells to undergo astrocytic differentiation selectively in the injured CNS. These effects are considered to coordinate to prevent the CNS repair after traumatic injury. Consistently, we previously reported that the administration of anti-IL-6 receptor antibody (MR16-1) immediately after spinal cord injury in mice decreased the number of invading inflammatory cells and the severity of connective tissue scar formation, and led to improved functional recovery. These findings suggest that neutralization of IL-6 signaling in the acute phase of SCI will be beneficial for CNS repair. A critical merit of this anti-IL-6 receptor antibody is that humanized antibody to human IL-6 receptor (MRA; Atlizumab) has already been reshaped. However, there are several studies which show beneficial aspects of IL-6 signaling in the pathology of CNS trauma. Further investigation of the mechanisms how MR16-1 reduces tissue damage should be required for clinical application.</p>

　View Summary

<p>Mdm2 is the major inhibitor of the p53 tumor suppressor. Loss of Mdm2 in mice or in specific tissues of the mouse always yields p53-dependent lethal phenotypes. However, the role of Mdm2 in tissues with high turnover capacity is unknown. We have engineered mice lacking Mdm2 in the intestinal epithelium using the Cre/LoxP system. Loss of Mdm2 (Mdm2^intΔ) results in viable animals, but neonates display multiple intestinal abnormalities such as hyperplasia, enterocyte vacuolization, and inflammation. These defects correlate with a drastic increase in p53-dependent apoptosis in highly proliferative and differentiated cells. Unexpectedly, the observed phenotypes disappear with age. The tissue selects against Mdm2-null cells and increases its proliferative capacity. Additionally, the intestinal stem and progenitor cell populations are enriched leading to an increase in crypt fission events. Enhanced proliferation is achieved by activation of the canonical Wnt and EGFR-mediated Ras/MAPK pathways. While Mdm2 is a critical inhibitor of p53 in the intestinal epithelium, the tissue employs a series of processes that compensate for cell death.</p>
