Infection with the trematode parasite Schistosoma mansoni results in distinct heterogeneity of disease severity both in humans and in mice. In the experimental mouse model, severe disease is characterized by pronounced hepatic egg-induced granulomatous inflammation mediated by CD4 Th17 cells, whereas mild disease is associated with reduced hepatic inflammation in a Th2-skewed cytokine environme...

Abstract BACKGROUND PCNSL is an aggressive brain tumor accounting for 3% of all CNS malignancies and associated with poor prognosis. Standard care treatment includes induction high-dose methotrexate based chemoimmunotherapy followed by consolidation autologous stem cell transplant or whole radiation. However, more than half patients cannot tolerate this intensive therapeutic intervention. Novel...

Sustained low-grade inflammation mediated by non-resolving inflammatory monocytes has long been suspected in the pathogenesis of atherosclerosis; however, the molecular mechanisms responsible for the sustainment of non-resolving inflammatory monocytes during atherosclerosis are poorly understood. Here we observe that subclinical endotoxemia, often seen in humans with chronic inflammation, aggra...

Nitric oxide (NO), an important effector molecule of the innate immune system, can also regulate adaptive immunity. In this study, the molecular effects of NO on the toll-like receptor signaling pathway were determined using interleukin-12 (IL-12) as an immunologically relevant target gene. The principal conclusion of these experiments is that NO inhibits IL-1 receptor-associated kinase (IRAK) ...

OBJECTIVE Reduced frequency of atherosclerotic plaques is observed in interleukin-1 receptor-associated kinase-1 (IRAK1)-deficient mice; however, the underlying mechanism is not clear. Therefore, this study investigate the role of IRAK1 in vascular smooth muscle cell proliferation and neointimal hyperplasia. APPROACH AND RESULTS Stimulation of rat primary vascular smooth muscle cells with fet...
