Both cellular and humoral functions of the immune system are modulated by the sympathetic nervous system (SNS). This interaction is mainly mediated by the release of catecholamines (CA) and their receptor-specific action on immune cells. However, neuropeptide Y (NPY), also present in sympathetic nerve terminals, is released upon SNS-stimulation. NPY(More)
Prior studies have revealed that the sympathetic nervous system regulates the clinical and pathological manifestations of experimental autoimmune encephalomyelitis (EAE), an autoimmune disease model mediated by Th1 T cells. Although the regulatory role of catecholamines has been indicated in the previous works, it remained possible that other sympathetic(More)
While leukotriene C4 (LTC4) was originally identified as a potent bronchoconstrictor, the compound has versatile biological activities besides inflammatory reactions. Although the high content of LTC4 has been reported in the hypothalamus and median eminence, the precise localization of the compound remained obscure. To elucidate its possible functions in(More)
Epstein-Barr virus (EBV), a ubiquitous human herpesvirus and an aetiological agent of infectious mononucleosis, has a unique tropism for B lymphocytes. Clinical and laboratory features of chronic active EBV infections are chronic or persistent infectious mononucleosis-like symptoms and high antibody titre against early antigens (EA). Kawasaki disease (KD),(More)
In rats splenic natural killer (NK) cell activity was found to be significantly higher following chronic uncontrollable electrical stimulation of the lateral hypothalamus in fully conscious rats, compared to sham-operated rats. In a pre-test study, all rats had demonstrated that the electrode site had self-stimulating properties, which supports the(More)
BACKGROUND Alexithymia is a psychological trait characterized by a difficulty in verbalizing feelings, which has been associated with a number of illnesses, including bronchial asthma and cancer. METHODS In order to understand how psychological variables such as alexithymia affect physical health, we compared the lymphocyte subsets of men (n = 97, mean(More)
Though immune outcome is known to be determined by which helper T cell response predominates, no local mechanism has yet been established which can explain how the neuronal system may control this. It is possible that the nervous system releases neuropeptides at specific local sites of infection or challenge, which triggers lymphocytes at those points to(More)
Staged transsphenoidal surgery was performed in seven patients with nonfunctioning pituitary adenomas with suprasellar extension. Remnant adenomas were present in a supersellar position after complete removal of the intrasellar tumor, and did not descend into the sella because of the fibrous nature in five patients or fibrous nature and dumbbell shape in(More)
Repeated use of methamphetamine (MAP) is known to cause neurotoxicity in the dopaminergic neurons of the striatum. Recently, we reported that FK506, a calcineurin inhibitor and immunosuppressive agent, could attenuate acute behavioral changes and the development of sensitization after administration of MAP. In this study, we investigated the effects of(More)
Pathological and biochemical studies were performed on a 9-month-old boxer dog with progressive neurological abnormality. Histological examination revealed marked neuronal storage throughout the central nervous system and histiocytic storage in the reticuloendothelial system. Ultrastructurally, the neuronal storage consisted of accumulation of concentric(More)
