The Neuropathy In Hereditary Transthyretin Amyloidosis (Attrv): A Narrative Review.

J Peripher Nerv Syst 2021 May 7. Epub 2021 May 7.

Department of Neuroscience, Reproductive and Odontostomatological Science, University of Naples "Federico II", Naples, Italy.

Hereditary transthyretin amyloidosis (ATTRv) is a condition with adult-onset caused by mutation of transthyretin (TTR) gene and characterized by extracellular deposition of amyloid fibrils in tissue, expecially in peripheral nervous system (PNS) and heart. The PNS involvement lead to a rapidly progressive and disabling sensory-motor axonal neuropathy. Although awareness among neurologist raised in last years thank to new treatment options, ATTRv is frequently misdiagnosed and thus correct diagnosis can be delayed by several years. Read More

Functional Importance of Transient Receptor Potential (TRP) Channels in Neurological Disorders.

Front Cell Dev Biol 2021 4;9:611773. Epub 2021 Mar 4.

Gachon Pain Center and Department of Physiology, Gachon University College of Medicine, Incheon, South Korea.

Transient receptor potential (TRP) channels are transmembrane protein complexes that play important roles in the physiology and pathophysiology of both the central nervous system (CNS) and the peripheral nerve system (PNS). TRP channels function as non-selective cation channels that are activated by several chemical, mechanical, and thermal stimuli as well as by pH, osmolarity, and several endogenous or exogenous ligands, second messengers, and signaling molecules. On the pathophysiological side, these channels have been shown to play essential roles in the reproductive system, kidney, pancreas, lung, bone, intestine, as well as in neuropathic pain in both the CNS and PNS.

Hautarzt 2021 Apr 4;72(4):299-306. Epub 2021 Mar 4.

Medizinische Klinik B, Universitätsklinikum Münster, Münster, Deutschland.

Skin is commonly affected by neuroendorine paraneoplastic syndromes (PNS). This is due to the expression of receptors in the skin by which abnormally secreted neuroendocrine hormones and mediators elicit directly, and indirectly, cutaneous key signs and thus facilitate early diagnosis of these diseases. In acromegaly, induction of the growth hormone-insulin-like growth factor‑1 axis results in trophic changes of the acral portions of the skin and mucosal membranes including cutis verticis gyrata.

New evidence for secondary axonal degeneration in demyelinating neuropathies.

Neurosci Lett 2021 01 24;744:135595. Epub 2020 Dec 24.

Department of Neurology, Neuromuscular Division, Johns Hopkins School of Medicine, Baltimore, MD, United States. Electronic address:

Development of peripheral nervous system (PNS) myelin involves a coordinated series of events between growing axons and the Schwann cell (SC) progenitors that will eventually ensheath them. Myelin sheaths have evolved out of necessity to maintain rapid impulse propagation while accounting for body space constraints. However, myelinating SCs perform additional critical functions that are required to preserve axonal integrity including mitigating energy consumption by establishing the nodal architecture, regulating axon caliber by organizing axonal cytoskeleton networks, providing trophic and potentially metabolic support, possibly supplying genetic translation materials and protecting axons from toxic insults.

MOG antibody-related disease with recurrent optic neuritis and sensory polyradiculoneuropathy: A case report.

Mult Scler Relat Disord 2020 Nov 21;46:102597. Epub 2020 Oct 21.

Department of Neurology and Strokology, Nagasaki University Hospital, 1-7-1 Sakamoto, Nagasaki 852-8501, Japan.

Myelin oligodendrocyte glycoprotein (MOG) antibody-related diseases are inflammatory demyelinating conditions of the central nervous system (CNS) that induce a broad spectrum of symptoms. Since MOG is expressed exclusively in the CNS, the lesions are thought to be confined to the CNS. However, few cases of MOG antibody-related disease involve the peripheral nervous system (PNS); the mechanisms underlying such PNS involvement remain unclear. Read More

Neurotransmitter and neuropeptide regulation of mast cell function: a systematic review.

J Neuroinflammation 2020 Nov 25;17(1):356. Epub 2020 Nov 25.

Department of Pathogen Biology and Immunology, School of Basic Medical Sciences, Nanchang University, 461 Bayi Avenue, Nanchang, 330006, Jiangxi Province, People's Republic of China.

The existence of the neural control of mast cell functions has long been proposed. Mast cells (MCs) are localized in association with the peripheral nervous system (PNS) and the brain, where they are closely aligned, anatomically and functionally, with neurons and neuronal processes throughout the body. They express receptors for and are regulated by various neurotransmitters, neuropeptides, and other neuromodulators. Read More

Is MS affecting the CNS only? Lessons from clinic to myelin pathophysiology.

Neurol Neuroimmunol Neuroinflamm 2021 01 24;8(1). Epub 2020 Nov 24.

From the Department of Anatomy and Neurosciences (E.O., A.L., J.J.G.G., A.-M.v.D.), Department of Neurology (E.M.M.S.), and Department of Child Neurology (E.O.), Amsterdam UMC, Vrije Universiteit Amsterdam, Amsterdam Neuroscience, the Netherlands.

MS is regarded as a disease of the CNS where a combination of demyelination, inflammation, and axonal degeneration results in neurologic disability. However, various studies have also shown that the peripheral nervous system (PNS) can be involved in MS, expanding the consequences of this disorder outside the brain and spinal cord, and providing food for thought to the still unanswered questions about MS origin and treatment. Here, we review the emerging concept of PNS involvement in MS by looking at it from a clinical, molecular, and biochemical point of view. Read More
