Central nervous system (CNS)–resident natural killer cells suppress Th17 responses and CNS autoimmune pathology

Natural killer (NK) cells of the innate immune system can profoundly impact the development of adaptive immune responses. Inflammatory and autoimmune responses in anatomical locations such as the central nervous system (CNS) differ substantially from those found in peripheral organs. We show in a mouse model of multiple sclerosis that NK cell enrichment results in disease amelioration, whereas ...

Central Nervous System Infection Responses and Bacterial Clearance during Th1 and Th17 Cells Regulate Innate Immune

P134: Central Nervous System and Blood Biomarker in Stroke, CNS Bleeding, Epilepsy, and Traumatic CNS Injury; MicroRNAs

A Central nervous system (CNS) hemorrhage is bleeding in or around the brain and spinal cord. Reasons of CNS hemorrhage include high blood pressure, cancers, drug abuse, abnormally weak blood vessels that leakage, and trauma. Regression of CNS bleeding was confirmed to be relatively repetitive in patients with severe FV, FX, FVII and FXIII deficiencies. Generally in CNS hemorrhage, radiological...

Inhibition of autoimmune Th17 cell responses by pain killer ketamine

Ketamine is widely used in animals and humans as a systemic anesthetic. Although several immune-modulatory functions of ketamine have been reported, the effects of ketamine on the differentiation of Th17 cell are unknown. We found that ketamine significantly diminished the frequency of IL-17-producers among CD4+ T cells stimulated under Th17-skewing conditions. Mechanistic studies showed that k...

Central nervous system acute lymphoblastic leukemia: role of natural killer cells.

Central nervous system acute lymphoblastic leukemia (CNS-ALL) is a major clinical problem. Prophylactic therapy is neurotoxic, and a third of the relapses involve the CNS. Increased expression of interleukin 15 (IL-15) in leukemic blasts is associated with increased risk for CNS-ALL. Using in vivo models for CNS leukemia caused by mouse T-ALL and human xenografts of ALL cells, we demonstrate th...
