When human recombinant interferon-α2 diluted in saline was injected s.c. into rabbits, the total amount recovered in thoracic lymph was less than 0.4%. Recoveries increased from 2- to 8-fold if interferon was injected in 4% albumin or with hyaluronidase, respectively. Albumin added to interferon acts as an interstitial fluid expander, thus favoring(More)
In the course of a project aimed to clarify the molecular mechanisms by which phorbol 12-myristate 13-acetate (PMA)-activated forms of protein kinase C (PKC) promote growth arrest in an MCF-7 cell line, we found that the PKCdelta inhibitor Rottlerin was able by itself to block cell proliferation. In the current study, we investigated further the(More)
We recently found that Rottlerin not only inhibits proliferation but also causes Bcl-2- and Beclin 1-independent autophagic death in apoptosis-resistant breast adenocarcinoma MCF-7 cells. Having excluded a role for canonical signaling pathways, the current study was aimed to investigate the contribution of the AMPK/mTOR axis in autophagy induction and to(More)
There is increasing evidence that neuropeptide modulation of the immune response is an important physiological phenomenon which involves the interaction of peptidergic neuromodulators with specific neuropeptide receptors on the plasma membrane of immune effector cells. Many studies have examined the effect of neuropeptides on mitogen-induced lymphocyte(More)
The aim of the present study was to investigate the effects of a 3-week residential multidisciplinary non-pharmacological treatment program (including individually prescribed aerobic exercise and cognitive-behavioral therapy) on fibromyalgia symptoms and hypothalamic-pituitary-adrenal (HPA) axis function. Salivary and venous blood samples were collected(More)
Immune and neuroendocrine systems interact at various levels. In particular, either cytokines activate the hypothalamus-pituitary-adrenal axis (HPA) or corticotropin-releasing hormone (CRH) induces the release of beta-endorphin from peripheral human mononuclear cells. The aim of the present study was to investigate whether CRH may affect cytokine production(More)
Glucocorticoid receptors (GR) are ubiquitous molecules and are present also in the hippocampus and in several other nervous and immune tissues. Peripheral blood mononuclear cells (PBMCs) are a good model for studies of GR in humans. Glucocorticoids are important for maintaining cellular and humoral homeostasis and are key mediators of neuroendocrine-immune(More)
The renal handling of human interferon-alpha has been evaluated by using an isolated and perfused rabbit kidney. IFN-alpha disappears from plasma with a t1/2 of 81 min and the fractional turnover rate is 0.84%/min. About 47 molecules of IFN-alpha are filtrated with 100 molecules of creatinine but most of the IFN is absorbed by tubular cells. This is the(More)
The behavioral and immunoendocrine effects of formalin-induced pain were studied in male rats following a subcutaneous injection of formalin (50 microliters; 0.1%, F01 groups, 10%, F10 groups) or sham injection (control groups). After treatment, animals were tested in a transparent open field for either 30 or 60 min and thereafter sacrificed by(More)
Since the ability of cancer cells to evade apoptosis often limits the efficacy of radiotherapy and chemotherapy, autophagy is emerging as an alternative target to promote cell death. Therefore, we wondered whether Rottlerin, a natural polyphenolic compound with antiproliferative effects in several cell types, can induce cell death in MCF-7 breast cancer(More)
