BACKGROUND Thymectomy (Tx) is a common therapeutic option to treat myasthenia gravis (MG), but its effects on the immune system are still obscure in humans. OBJECTIVE We sought to evaluate long-term immunologic effects of therapeutic Tx in patients with MG. METHODS T- and B-cell subsets and T-cell repertoire were analyzed in 35 patients with MG, 16 with(More)
 The passive transfer of antibodies and vaccination procedures against p185, the erbB2/neu oncoprotein, are approaches being explored for treatment of human breast cancer. We now report the possibility of using the erbB2/neu gene as an immunogen. This study demonstrates that intramuscular or intradermal injections of rat neuNT full-length DNA into mice(More)
erbB2/neu, an overexpressed oncogene product, has been proposed as a human cancer vaccine target. In the present study, transgenic (rat neuNT oncogene) FVB/neu mice, developing metastasizable mammary carcinoma, were immunized with a plasmid DNA encoding are not tolerant to the self antigen and sequences. We report that transgenic tumour-bearing mice, like(More)
Autophagy plays an important role in neoplastic transformation of cells and in resistance of cancer cells to radio- and chemotherapy. p62 (SQSTM1) is a key component of autophagic machinery which is also involved in signal transduction. Although recent empirical observations demonstrated that p62 is overexpressed in variety of human tumors, a mechanism of(More)
We recently reported that a DNA plasmid coding p62-SQSTM1 acts as an effective anti tumor vaccine against both transplantable mouse tumors and canine spontaneous mammary neoplasms. Here we report the unexpected finding that intramuscular delivery of p62 DNA exerts a powerful anti-osteoporotic activity in a mouse model of inflammatory bone loss (i.e,(More)
BACKGROUND We have previously shown that xenogeneic DNA vaccines encoding rat neu and melanosomal differentiation Ag induce tumor immunity. Others have developed vaccines targeting tumor neovasculature. Tumor endothelial marker 8 (TEM8) is expressed in the neovasculature of human tumors, and in the mouse melanoma B16, but its expression is limited in normal(More)
The Fas ligand (FasL) and its receptor Fas (APO-1 or CD95) are members, respectively, of the tumor necrosis factor family that, upon interaction with each other, play a key role in the initiation of one apoptotic pathway. Faulty regulation of the Fas system has been described in a variety of human tumors with different histogenetic origin. Here, we describe(More)
Low-molecular-weight peptides are linked to the chromatin DNA of several tissues, from which they can be dissociated by alkaline extraction at pH 9.5. The level of the active peptide fraction ranges between 10 and 35 micrograms/mg DNA. The removal of peptides from DNA causes a relevant amplification of DNA template capacity for prokaryotic and eukaryotic(More)
Low molecular weight peptides from calf thymus cause a strong dose-dependent stabilization of the DNA. The strength of DNA-peptide interaction is pH-dependent and decreases rapidly above pH 6.5. Moreover the complete kinetics of DNA denaturation and renaturation demonstrates that the peptide fraction increases significantly the DNA renaturation mostly at(More)
