IL-12, a cytokine produced by microglia, may regulate cellular immunity at a localized level in the CNS. To investigate this further, we examined the consequences of peripheral immune stimulation without specific autoantigen in wild-type or transgenic (termed GF-IL12) mice with astrocyte production of the bioactive IL-12 p75 heterodimer. Active immunization with CFA and pertussis toxin, a procedure known to stimulate a robust type 1-biased immune response, produced CNS immune pathology from which GF-IL12 but not wild-type mice developed signs of clinical disease consisting of loss of activity, piloerection, mild tremor, and motor change. All immunized mice had some degree of mononuclear cell infiltration into the brain; however, the severity of this was markedly increased in GF-IL12 mice where leukocytes accumulated in perivascular and parenchymal locations. Accumulating cells consisted of CD4(+) and CD8(+) T cells and macrophage/microglia. Moreover, expression of cytokines (IFN-gamma and TNF), chemokines (IFN-inducible protein-10 and RANTES), the immune accessory molecules, MHC class II, B7.2, ICAM-1 and VCAM-1, and NO synthase-2 was induced in the CNS of the GF-IL12 mice. Therefore, peripheral immunization of GF-IL12 but not wild-type mice can provoke active type 1 immunity in the brain-a process that does not require CNS-specific immunizing autoantigen. These findings indicate that the cytokine milieu of a tissue can dramatically influence the development of intrinsic immune responses and associated pathology.

A 65-year-old man was admitted for high-grade fever with a shaking chill and general fatigue. Chest X-ray showed cardiomegaly, and echocardiography revealed a large amount of pericardial effusion. Emergency pericardiocentesis was performed, and Salmonella enteritidis was found in pericardial fluids. We diagnosed purulent pericarditis with S. enteritidis, and administered antibiotics. While high-grade fever resolved 10 days after beginning of treatment, effusive-constrictive pericarditis (ECP) without definite symptoms persisted for 2 months. Because of the improvement of his hemodynamic states on cardiac catheterization after 1 year, an operative procedure was not required. He was diagnosed as having CD4/CD8 depression without apparent diseases. There are few reports of pericarditis with S. enteritidis, and we believe this case might be only the second recorded case of ECP with S. enteritidis.

HTLV-associated myelopathy/tropical spastic paraparesis (HAM/TSP) is a neurodegenerative disease of the central nervous system induced by human T-lymphotropic virus type 1. As a potential therapeutic approach, we previously suggested reducing the proviral load by modulating lysine deacetylase activity using valproic acid (VPA) and exposing virus-positive cells to the host immune response. We conducted a single-center, 2-year, open-label trial, with 19 HAM/TSP volunteers treated with oral VPA. Proviral load, CD38/HLA-DR expression, and CD8(+) lysis efficiency were not significantly affected by VPA. Mean scores of HAM/TSP disability did not differ between baseline and final visit. Walking Time Test increased significantly (> 20%) in 3 patients and was in keeping with minor VPA side effects (drowsiness and tremor). Walking Time Test improved rapidly after VPA discontinuation. We conclude that long-term treatment with VPA is safe in HAM/TSP.
