cell replacement therapy has provided the basis for future clinical applications to treat central nervous system injuries fallowing by car accidents. induced functional neurons are an option for replacing the lost neurons. the ability to monitor changes in membrane potential is a useful tool for studying neuronal function, but there are only limited options available at present. here, investiga...

Our previous studies have shown that median and ulnar nerve lesion induced calbindin (CB) immunoreactivity in some injured motoneurons in developing rats. Motoneuron death induced by sciatic nerve transection in neonatal rats has been related to induction of neuronal isoform of nitric oxide synthase (nNOS). The present study investigated whether expression of CB and nicotinomid adenin dinucleot...

The ciliary neurotrophic factor alpha-receptor (CNTFRalpha) is required for motoneuron survival during development, but the relevant ligand(s) has not been determined. One candidate is the heterodimer formed by cardiotrophin-like cytokine (CLC) and cytokine-like factor 1 (CLF). CLC/CLF binds to CNTFRalpha and enhances the survival of developing motoneurons in vitro; whether this novel trophic f...

background and objective: as apoptotic cell death is extremely involved in physiological development and many pathological situations such as cancer and neurodegenerative diseases, the understanding of its molecular machinery can be useful in designing new therapeutic strategies. the present study investigated the temporal expression of the proapoptotic protein bax in adult spinal motoneurons. ...

Induced pluripotent cell-derived motoneurons (iPSCMNs) are sought for use in cell replacement therapies and treatment strategies for motoneuron diseases such as amyotrophic lateral sclerosis (ALS). However, much remains unknown about the physiological properties of iPSCMNs and how they compare with endogenous spinal motoneurons or embryonic stem cell-derived motoneurons (ESCMNs). In the present...

In anesthetized cats, phrenic motoneurons were intracellularly labeled with HRP. Immunohistochemistry was used to localize serotonin-like immunoreactivity that was present in numerous boutons and nerve fibers within the ventral horn of the C5 spinal segment. Immunoreactive boutons were frequently found in apposition to phrenic motoneurons, but these close contacts were more common on the dendri...

Diversity in the expression of ion channel proteins among neurons allows a wide range of excitability, growth and functional regulation. Ether-a-go-go (EAG), a member of the voltage-gated K channels, was characterized by spontaneous firing in nerve terminals and enhanced neurotransmitter release. In situ whole-cell patch-clamp recordings performed from the somata of Drosophila larval thoracic a...
