Although immunity against intracellular pathogens is primarily provided by CD8 T lymphocytes that recognize pathogen-derived peptides presented by major histocompatibility complex (MHC) class Ia molecules, MHC class Ib-restricted CD8 T cells have been implicated in antiviral immunity. Using mouse polyoma virus (PyV), we found that MHC class Ia-deficient(More)
The neuroendocrine system plays a key role in the regulation of the secretion of the thymic peptide, thymulin, but it remains to be determined whether thymulin exerts reciprocal regulatory actions on the functional activity of the hypothalamo-pituitary axis. In the present study, we have used a well established in vitro preparation to examine the influence(More)
1. Preliminary studies in our laboratories showed that the synthetic xanthine analogue denbufylline, a selective type 4 phosphodiesterase (PDE-4) inhibitor, is a potent activator of the hypothalamo-pituitary-adrenal (HPA) axis when given orally to adult male rats. This paper describes the results of experiments in which well established in vivo and in vitro(More)
