Several reviews have so far pointed out on the relevant physiological and pharmacological role exerted by neuroactive steroids in the central nervous system. In the present review we summarize observations indicating that synthesis and metabolism of neuroactive steroids also occur in the peripheral nerves. Interestingly, peripheral nervous system is also a target of their action. Indeed, as her...

The events that follow axonal interruption (axotomy) reveal an important and fundamental difference between the peripheral and central components of the adult mammalian nervous system. Following transection of peripheral nerve axons, the proximal axonal portion is able to regenerate through the distal part of the nerve and may, under appropriate conditions, re-innervate the original target (sen...

The assessment of circulating neurotransmitters: noradrenaline, adrenaline, dopamine, platelet serotonin, plasma serotonin and plasma tryptophan before and after many types of stressor agents and neuropharmacological drugs carried out over the last thirty years allowed us to accumulate information dealing with the central nervous system (CNS) versus the peripheral autonomic nervous system (ANS)...

Vertebrate embryos display segmental patterns in many trunk structures, including somites and peripheral nervous system elements. Previous work in avian embryos suggests a role for somite-derived sclerotome in segmental patterning of the peripheral nervous system. We investigated sclerotome development and tested its role in patterning motor axons and dorsal root ganglia in embryonic zebrafish....

Neurolymphomatosis (NL) refers to a lymphomatous infiltration of peripheral nerves associated with central nervous system or systemic lymphoma, or alternatively, neurodiagnostic evidence of nerve enhancement and/or enlargement beyond the dural sleeve in the setting of primary central nervous system lymphoma or systemic lymphoma. NL is a rare complication of systemic cancer with heterogeneous cl...

Prognostic factors for peripheral nervous system (PNS) manifestations in primary Sjögren Syndrome (pSS) are essential predicting and preventing disease-related disability. Given the established relationship between vitamin B12 deficiency pSS, we aimed to investigate predictive value of low concentration Sjögren's induced neuropathy (PN).

INTRODUCTION: Repairing the damaged nervous system is one of the greatest challenges facing regenerative medicine. Research into nervous system repair can be separated into two broad areas covering the central nervous system (CNS) and the peripheral nervous system (PNS). Damage to peripheral nerves can lead to loss of sensation, motor function and muscle weakness, but the PNS is capable of sign...

parkinson's disease (pd) is a very common neurodegenerative disease among the elderly population. current treatments for parkinson’s disease are based on symptom therapy but not the underlying cause of the disease. this disorder is caused neuronal death which triggers the activation of resident glial cells. this situation leads to neuroinflammation in the central nervous system. activated ...
