Using the murine parasite Plasmodium yoelii (Py) as a model for malaria vaccine development, we have previously shown that a DNA plasmid encoding the Py circumsporozoite protein (PyCSP) can protect mice against sporozoite infection. We now report that mixing a new plasmid PyCSP1012 with a plasmid encoding murine granulocyte-macrophage colony-stimulating(More)
OBJECTIVE To examine the in vivo mechanisms of suppression of T lymphocyte function in patients with Behçet's disease (BD) undergoing long-term treatment with tacrolimus (FK-506). METHODS Intracellular proteins were analyzed by immunoprecipitation and Western blotting. Messenger RNA expression was studied by a polymerase chain reaction-based technique. (More)
OBJECTIVE The Fas/Fas ligand (FasL) system has been assigned a pivotal role in the establishment and maintenance of peripheral tolerance, and mice having defects in the Fas/FasL system are known to develop lupus-like symptoms. However, it remains unclear whether the Fas/FasL system is involved in the pathogenesis of systemic lupus erythematosus (SLE) in(More)
A plasmid DNA vaccine encoding the circumsporozoite protein of malaria (pCSP) induces tolerance rather than immunity when administered to newborn mice. We find that this tolerance persists for >1 yr after neonatal pCSP administration and interferes with the induction of protective immunity in animals challenged with live sporozoites. Susceptibility to(More)
DNA technology has facilitated the development of plasmid-based vaccines designed to prevent viral, bacterial and parasitic infections. The rapid transition of these novel vaccines from the laboratory to the clinic raises important safety concerns. Our review examines whether DNA vaccines (i) are likely to induce systemic or organ-specific auto-immune(More)
Cytokine-encoding DNA plasmids can act as ‘genetic adjuvants’, improving the immune response stimulated by co-administered DNA vaccines. We examined whether plasmids encoding the Th1 cytokine IFNγ (pIFNγ) or the Th2 cytokine IL-4 (pIL-4) have long-term effects on immune homeostasis when administered to adult mice, or alter immune maturation in neonates.(More)
AIMS To investigate the relationship between urinary bladder mucosal expression of β3-adrenoceptor (AR) mRNA and urodynamic findings in patients with lower urinary tract symptoms and benign prostatic obstruction (BPO). METHODS During surgical prostate resection of 32 BPO patients, mucosal biopsies were collected and analyzed by reverse transcriptase(More)
This study explores the effect of priming rhesus monkeys with an Ad5/35 vector expressing simian immunodeficiency virus (SIV) gag and gp120, and then boosting the animals with an modified vaccinia virus Ankara (MVA) vector encoding the same antigens after a 2-month interval. The animals were intravenously challenged with 100 TCID50 of highly pathogenic(More)
PURPOSE Liposome encapsulated doxorubicin administered to the pelvic lymph nodes might be effective against pelvic node metastasis. We determined whether the drug can be delivered to the nodes via the bladder wall. MATERIALS AND METHODS Ten patients underwent endoscopic administration of 10 mg. liposomal doxorubicin into the bladder wall 3 days before(More)
Most pelvic organ prolapse (POP) patients have lower urinary tract symptoms (LUTS) before and after POP surgery. LUTS of POP patients consist of various storage and voiding symptoms from anatomical causes. Videourodynamic examination for POP patients provides accurate information about morphological findings of the bladder and urethra, and lower urinary(More)
