Outline of Final Research Achievements |
We demonstrated that restraint stress markedly and rapidly induces the blood level of Galectin-1 (Gal-1). In this study, we revealed that Gal-1 levels in the spleen and thymus increased after the restraint stress. Immunohistochemical analysis showed that immunoreactivity for Gal-1 was detected in the periarterial lymphatic sheath (PALS) of the spleen and in the medulla of the thymus and the staining intensity increased after restraint stress. The Gal-1 co-localized with CD45+ lymphocytes in the PALS and the medulla. These results suggested that stress-induced Gal-1 in blood may modulate the immune response through apoptosis by binding to CD45+ lymphocytes. Furthermore, Gal-1 levels in the pancreas also increased after the restraint stress and the immunoreactive cells were corresponded to fibroblasts and smooth muscle cells of blood capillary located pancreatic interlobullus. Gal-1 may participate in one of pancreatic responses against stress.
