In the present undertaking, the distribution of odontoblast processes in human dentin was determined through the DiI carbocyanine dye fluorescent staining of the cell membrane, while F-actin was identified by rhodamine-phalloidin. Confocal laser scanning microscopy revealed intense labeling for both agents in inner dentin, while transmission electron(More)
Neuropeptide Y (NPY) and peptide YY (PYY) are structurally related peptides with a variety of known functions. The role of these peptides in the skin is largely unknown, although NPY-like immunoreactivity has been reported in the epidermis. The recent report that these peptides have antimicrobial properties suggests that NPY and PYY may contribute to the(More)
The regions of expression of Ripply1 and Ripply2, presumptive transcriptional corepressors, overlap at the presomitic mesoderm during somitogenesis in mouse and zebrafish. Ripply1 is required for somite segmentation in zebrafish, but the developmental role of Ripply2 remains unclear in both species. Here, we generated Ripply2 knock-out mice to investigate(More)
Tumor-reactive T cells, known as tumor-infiltrating lymphocyte(TIL)s are known to infiltrate various tumors. Although Ills exert cytotoxic activities against tumor cells, only a small percentage of tumors usually contain TILs that specifically react to tumor antigens. Because the exact role of these lymphocytes is unclear, we investigated the mechanisms of(More)
