To establish the possible roles of oxidative stress, inflammatory processes and other unknown mechanisms in neurodegeneration, we investigated brain gene alterations in N-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) mice model of Parkinson's disease using Atlas mouse cDNA expression array membrane. The expression of 51 different genes involved in(More)
In the present study we demonstrate neuroprotective property of green tea extract and (-)-epigallocatechin-3-gallate in N-methyl-4-phenyl-1,2,3,6-tetrahydropyridine mice model of Parkinson's disease. N-Methyl-4-phenyl-1,2,3,6-tetrahydropyridine neurotoxin caused dopamine neuron loss in substantia nigra concomitant with a depletion in striatal dopamine and(More)
In order to establish whether the antioxidant and iron-chelating activities of R-apomorphine (R-APO), a D(1)-D(2) receptor agonist, may contribute to its neuroprotective property, its S-isomer, which is not a dopamine agonist, was studied. The neuroprotective property of R- and S-APO has been studied in the MPTP model of Parkinson's disease (PD). Both S-APO(More)
One of the prominent pathological features of Parkinson's disease (PD) is the abnormal accumulation of iron in the substantia nigra pars compacta (SNpc), in the reactive microglia, and in association with neuromelanin, within the melanin-containing dopamine (DA) neurons. Lewy body, the morphological hallmark of PD, is composed of lipids, redox-active iron,(More)
IFN-␥-inducible protein 10 (IP-10) is a CXC chemokine that is thought to manifest a proinflammatory role because it stimulates the directional migration of activated T cells, particularly Th1 cells. It is an open question whether this chemokine is also directly involved in T cell polarization. We show here that during the course of adjuvant-induced(More)
Recently, we reported specific brain gene expression changes in the chronic MPTP model inthe late stage of degeneration, employing cDNA expression array, which indicate a "domino" cascade of events involved in neuronal cell death. In an attempt to elucidate early gene expression profile in the region of the substantia nigra (SN) and the striatum of acute(More)
IL-27 is a recently defined family member of the long-chain four-helix bundle cytokines, which consists of EBI3, an IL-12p40-related protein, and p28, an IL-12p35-related polypeptide. The role of IL-27 in the regulation of inflammatory autoimmune diseases has never been studied. The current study uses the DNA vaccination technology, and highly specific Abs(More)
Puberty is associated with an increase in the plasma concentration of sex steroids, GH, and insulin-like growth factor-I (IGF-I). Gonadal steroid hormones are important for the normal pubertal growth spurt and skeletal growth. The mechanism by which gonadal steroids induce skeletal growth is still not fully understood. To better understand the direct effect(More)
We developed a neonatal mouse model to investigate in vivo anabolic effects of intact PTH (1-84) and its two fragments PTH (1-34) and PTH (28-48) and of the N-terminal fragment of PTH-related peptide [PTHrP (1-34)]. Two-day-old mice were injected with low-dose (0.05 microg/g body weight) and high-dose (0.2 microg/g body weight) of each of these peptides(More)
