Cytokine interleukin-6 (IL-6) has been well shown to be elevated in brain injury and diseases. However, the significance of IL-6 production in such neuropathologic states remains controversial, and the intracellular signal-transduction pathways involved in the brain IL-6 action are primarily unclear. We previously indicated that exogenous IL-6 protected(More)
Our previous work has shown that the cerebellar fastigial nucleus (FN) is involved in modulation of lymphocyte function. Herein, we investigated effect of FN γ-aminobutyric acid (GABA)-ergic projections to the hypothalamus on lymphocytes to understand pathways and mechanisms underlying cerebellar immunomodulation. By injection of Texas red dextran amine(More)
Dopamine (DA), a neurotransmitter in the nervous system, has been shown to modulate immune function. We have previously reported that five subtypes of DA receptors, including D1R, D2R, D3R, D4R and D5R, are expressed in T lymphocytes and they are involved in regulation of T cells. However, roles of these DA receptor subtypes and their coupled(More)
OBJECTIVES We explored effect of glutamatergic neurons in the fastigial nucleus (FN), one of three cerebellar nuclei, on humoral immunity and revealed that this effect was mediated by the hypothalamus via FN-hypothalamic glutamatergic transmission. METHODS Rats were immunized with bovine serum albumin (BSA). On the third day after the immunization,(More)
We have previously shown that the cerebellum regulates functions of T, B and natural killer (NK) cells. Herein, we provide further evidence for cerebellar immunomodulation at the profiles of differentiation and maturation of thymocytes and function of mature T lymphocytes. Neuronal bodies of the fastigial nuclei (FN), one of three cerebellar nuclei, were(More)
Our previous studies have shown that the cerebellar interposed nucleus (IN) modulates lymphocyte functions. As the cerebellum does not have a direct contact with the immune system, it is required to explore the pathway mediating the cerebellar immunomodulation. In this study, both lymphocyte percentage in peripheral leukocytes and lymphocyte proliferation(More)
AIM To explore the effect of cerebellar fastigial nuclei (FN)on lymphocyte function and the pathway mediating the effect. METHODS Kainic acid (KA) was microinjected into bilateral FN of rats to destroy neuronal bodies in the FN. On the eighth day after the surgery, lymphocyte percentage in the peripheral blood and level of sheep red blood(More)
T helper (Th)17 cells, a subset of CD4+ T lymphocytes, have strong pro-inflammatory property and appear to be essential in the pathogenesis of many inflammatory diseases. However, the involvement of Th17 cells in Parkinson’s disease (PD) that is characterized by a progressive degeneration of dopaminergic (DAergic) neurons in the nigrostriatal system is(More)
OBJECTIVE We previously showed that the cerebellum modulates the immune system. Here we determined whether cerebellar ataxia alters immunological function to further demonstrate an involvement of the cerebellum in immune modulation. METHODS Neurotoxin 3-acetylpyridine (3-AP) was intraperitoneally injected in rats to induce cerebellar ataxia. Behavior and(More)
Our previous work has shown that lesions of the cerebellar interposed nuclei (IN) suppress immune cell functions. Since there is no direct structural connection between the cerebellum and immune system, we explored the pathway mediating the cerebellar immunomodulation at the profile of cerebellohypothalamic projections to understand this modulation.(More)
