Abstract
We have previously developed a rat model of K. pneumoniae meningoencephalitis. Cortistatin (CST) is a recently discovered neuropeptide with endocrine activities in humans. In this study, we found that brain infection by K. pneumoniae increased endogenous prepro-CST messenger RNA expression, which oc...

Abstract
We examined the role of T cell immunoglobulin mucin 1 (Tim-1) in cisplatin-induced acute kidney injury using an inhibitory anti-Tim-1 antibody. Tim-1 acts to modulate T cell responses, but it is also expressed by damaged proximal tubules in the kidney, where it is known as kidney injury molecule-1 (...

Abstract
Our data show that at the site of infection in the footpad and in the draining popliteal lymph node, numbers of regulatory T cells remain unchanged between WT and IL-6-deficient mice. However, the spleens of IL-6(-/-) mice contained fewer regulatory T cells after infection with L. major. The develop...

Abstract
We analyzed the changes in FEV(1) after administration of a bronchodilator over a 3-year period in 2163 patients. A random-coefficient model was used to evaluate possible predictors of both FEV(1) levels and their changes over time.
The mean (±SE) rate of change in FEV(1) was a decl...

Abstract
We demonstrated that cholera induces an early proinflammatory cellular immune response that results in priming of Th1- and Th17-type cytokine responses to ex vivo antigenic stimulation and an increase in the ratio of Th1 to Th2 CD4(+) T-cell responses. Comparable priming of Th1 and Th17 responses, w...
