Parkinson's disease (PD) is a common age-associated neurodegenerative disorder. To date, stem cell transplantation therapy has been developed to replace lost or damaged neural cells in PD patients, in whom dopaminergic neuron cells are lost. Here, we show that CD44+ human amniotic fluid cells (HuAFCs) can be induced to become functional dopaminergic neuronal-like cells in vitro. Furthermore, wh...

In contrast to mammals, the spinal cord of adult zebrafish has the capacity to reinitiate generation of motor neurons after a lesion. Here we show that genes involved in motor neuron development, i.e., the ventral morphogen sonic hedgehog a (shha), as well as the transcription factors nkx6.1 and pax6, together with a Tg(olig2:egfp) transgene, are expressed in the unlesioned spinal cord of adult...

Neuroinflammation is a hallmark of Amyotrophic Lateral Sclerosis (ALS) in hSOD1G93A mouse models where microglial cells contribute to the progressive motor neuron degenerative process. S100-A8 and S100-A9 (also known as MRP8 MRP14, respectively) are cytoplasmic proteins expressed by inflammatory myeloid cells, including microglia macrophages. Mainly acting heterodimer, S100-A8/A9, when secreted...

Two types of glial fibrillary acidic protein-positive (GFAP+) astrocytes were found in cultures of developing rat optic nerve. Type 1 astrocytes had a fibroblast-like morphology, did not bind tetanus toxin or the monoclonal antibody A2B5 (both of which bind to specific polysialogangliosides), and were stimulated to divide by an extract of bovine pituitary and by epidermal growth factor (EGF). T...

Introduction: Increased oxidative stress is widely accepted to be a factor in the development and progression of Alzheimer’s disease. Triazine derivatives possess a wide range of pharmacological activities including anti-oxidative and anti-in.ammatory actions. In this study, we aimed to investigate the possible protective effect of 3-thioethyl-5,6-dimethoxyphenyl-1,2,4-triazine (TEDMT) on H2O2-...
