In this paper we demonstrated that by an adequate combination of different topological indices it is possible to select and design new active compounds in therapeutical scopes, with a very high efficiency level. Particularly successful the search "lead drugs", results show surprising ability methods describe molecular structures.
The members of the glial cell line-derived neurotrophic factor (GDNF) family factors (GDNF, neurturin, persephin, and artemin) are able to promote in vivo vitro survival different neuronal populations, including spinal cord motoneurons. These signal via multicomponent receptors that consist Ret receptor tyrosine kinase plus a member GDNF alpha (GRFalpha) glycosylphosphatidylinositol-linked coreceptors.

Abstract : Chick embryo spinal cord motoneurons develop a trophic response to some neurotrophins when they are maintained in culture the presence of muscle extract. Thus, after 2 days culture, brain‐derived neurotrophic factor (BDNF) promotes motoneuron survival. In present study we have analyzed intracellular pathways that may be involved BDNF‐induced We observed BDNF activated extracellular‐regulated kinase (ERK) mitogen‐activated protein (MAP) and phosphatidylinositol (Pl) 3‐kinase...
Moderate increases of intracellular Ca2+ concentration ([Ca2+]i), induced by either the activation tropomyosin receptor kinase (Trk) receptors for neurotrophins or neuronal activity, regulate different pathways and survival. In present report we demonstrate that glial cell line-derived neurotrophic factor (GDNF) treatment also induces [Ca2+]i elevation mobilizing this cation from internal stores. The effects increase after membrane depolarization are mainly mediated calmodulin (CaM)....
Abstract Spinal muscular atrophy (SMA) is a recessive autosomal neuromuscular disease, due to homozygous mutations or deletions in the telomeric survival motoneuron gene 1 ( SMN1 ). SMA characterized by motor impairment, muscle atrophy, and premature death following neuron (MN) degeneration. Emerging evidence suggests that dysregulation of autophagy contributes MN We here investigated role SMNdelta7 mouse model II (intermediate form disease) which leads impairment postnatal day 5 (P5) P13....
The dysfunction of TAR DNA-binding protein 43 (TDP-43) is implicated in various neurodegenerative diseases, though the specific contributions its toxic gain-of-function versus loss-of-function effects remain unclear. This study investigates impact TARDBP loss on cellular metabolism and viability using human-induced pluripotent stem cell-derived motor neurons HeLa cells. silencing led to reduced metabolic activity cell growth, accompanied by neurite degeneration decreased oxygen consumption...

In the present work, we find that elevation of extracellular K+ concentration promotes survival chick spinal cord motoneurons in vitro deprived any neurotrophic support. This treatment induces chronic depolarization neuronal plasma membrane, which activates L-type voltage-dependent Ca2+ channels, resulting influx and cytosolic free concentration. Pharmacological reduction intracellular or withdrawal reversed effects on survival. The response to membrane developed as an initial peak followed...
During embryonic development, most neuronal populations undergo a process usually referred to as naturally occurring death. For motoneurons (MTNs) of the lumbar spinal cord chick embryos, this takes place in well defined period time, between days 6 and 10 (E6–E10). Neurotrophins (NTs) are best characterized family neurotrophic factors exert their effects through activation specific Trk receptors. In vitro vivo studies have demonstrated that rodent survive response BDNF, NT3, NT4/5. contrast,...

Spinal Muscular Atrophy (SMA) is a severe genetic neuromuscular disorder that occurs in childhood and caused by misexpression of the survival motor neuron (SMN) protein. SMN reduction induces spinal cord motoneuron (MN) degeneration, which leads to progressive muscular atrophy weakness. The link between deficiency molecular mechanisms altered SMA cells remains unclear. Autophagy, deregulation intracellular pathways ERK hyperphosphorylation may contribute SMN-reduced MNs collapse, offering...
It has been reported that phosphoinositide 3-kinase (PI 3-kinase) and its downstream target, protein kinase B (PKB), play a central role in the signaling of cell survival triggered by neurotrophins (NTs). In this report, we have analyzed involvement Ca2+ calmodulin (CaM) activation PKB induced NTs. We found reduction intracellular concentration or functional blockade CaM abolished NGF-induced PC12 cells. Similar results were obtained cultures chicken spinal cord motoneurons treated with...
