REVIEW
Yuan Liu, Richard K Lee
Neurodegenerative eye diseases, such as glaucoma, cause irreversible vision loss in millions of patients worldwide, creating serious medical, economic and social issues. Like other mammalian central nervous system tracts, optic nerve intrinsically lacks the capacity for axonal growth and its surrounding environment is also non-permissive to regeneration. Any axonal damage also triggers a vicious cycle of retinal ganglion cell (RGC) death. Exploring methods that can enhance RGCs survival and promote axonal regeneration will not only enable vision restoration for millions of patients, but also shed light on the treatment of other neurodegenerative diseases...

Long-range axonal retrograde transport is a key mechanism for the cellular dissemination of neuro-invasive viruses, such as Borna Disease Virus (BDV), for which entry and egress sites are usually distant from the nucleus, where viral replication takes place. Although BDV is known to disseminate very efficiently in neurons, both in vivo and in primary cultures, the modalities of its axonal transport are still poorly characterized. In this work, we combined different methodological approaches, such as confocal microscopy and biochemical purification of endosomes, to study BDV retrograde transport...

BACKGROUND AND PURPOSE: Recombinant IFNß is one of the first line treatments in multiple sclerosis (MS), despite its lack of efficiency in some patients. In this context, mesenchymal stem cells (MSCs) represent a promising therapeutic alternative due to their immunomodulatory properties and multipotency. Moreover, taking advantage of their pathotropism ability, these cells can be genetically modified to be used as carriers for delivering or secreting therapeutic drugs into injured tissues...

Traumatic brain injury (TBI) is a major health and socioeconomic problem as it is associated with high rates of mortality and morbidity worldwide. Regulatory T cells (Tregs) have been reported to reduce inflammatory response in several diseases, including myasthenia gravis, viral myocarditis and cerebral infarction. The present study investigated the role of Tregs in mediating neuro‑protective effects in a mouse model of TBI. Initially, Treg levels were determined, and compared between the controlled cortical impact (CCI) model for moderate TBI and the sham group, by using flow cytometry and ELISA...

Acromegaly is a rare disease which is caused by a tumour in the anterior lobe of the pituitary gland. The tumour stimulates excessive production of the growth hormone. As a result, all the organs and tissues in the body are induced to grow. This growth is responsible for a wide range of symptoms, some of which can be neuro-psychiatric.<br/> AIM: To promote the early detection of acromegaly so that treatment can be started as soon as possible and further damage can be prevented.<br/> METHOD: We searched PubMed for articles relating to quality of life and cognitive, psychological and psychiatric symptoms and personality changes associated with acromegaly...

Colorectal cancer represents a severe public health issue. Recent studies have shown the essential role played by nerves and their neurotransmitters in tumor initiation and progression. The aim of this study is to asses the expression of beta 2-adrenergic receptors (β2A) for adrenaline and noradrenaline, and the expression of M3 muscarinic receptors (M3R) for acetylcholine (neurotransmitters produced and released by sympathetic and parasympathetic afferents of the digestive tract and also by the enteric nervous system) in different tumor gradings of colorectal adenocarcinoma, and also the tropomyosin receptor kinase A (TrkA) for the nerve growth factor produced by the cells of colorectal adenocarcinoma...

Recent advances in tissue engineering have encouraged researchers to endeavor the production of fully functional three-dimensional (3D) thick human tissues in vitro. Here, we report the fabrication of a fully innervated human skin tissue in vitro that recapitulates and replicates skin sensory function. Previous attempts to innervate in vitro 3D skin models did not demonstrate an effective functionality of the nerve network. In our approach, we initially engineer functional human skin tissue based on fibroblast-generated dermis and differentiated epidermis; then, we promote rat dorsal root ganglion (DRG) neurons axon ingrowth in the de-novo developed tissue...

BACKGROUND: Transforming growth factor-beta 1 (TGF-β1) regulates many processes after traumatic brain injury (TBI). Both Neuro AiD™ (MLC601) and astragaloside (AST) attenuate microglia activation in rats with TBI. The purpose of this study was to investigate whether MLC601 or AST improves output of TBI by affecting microglial expression of TGF-β1. MATERIALS AND METHODS: Adult male Sprague-Dawley rats (120 in number) were used to investigate the contribution of TGF-β1-containing microglia in the MLC601-mediated or the AST-mediated neuroprotection in the brain trauma condition using lateral fluid percussion injury...

We report on a female patient who received microvascular decompression due to hemifacial spasm. Neuro-Patch® was used during the operation to repair and replace damaged dura mater. Six days after the operation, the incision wound was found to be infected. Abscesses were present deep in the incision. However, because the artificial dura mater was attached so tightly to the original dura mater, the infection was not able to spread inside the skull. After 3 months of meticulous wound cleaning and drug treatment to promote the growth of granulation tissue, we were able to gradually achieve healing of the infection without having to remove the non-absorbable artificial dura mater...

The discovery of various driver pathways and targeted small molecule agents/antibodies have revolutionized the management of metastatic breast cancer. Currently, the major targets of clinical utility in breast cancer include the human epidermal growth factor receptor 2 (HER2) and epidermal growth factor receptor (EGFR), vascular endothelial growth factor (VEGF) receptor, mechanistic target of rapamycin (mTOR) pathway, and the cyclin-dependent kinase 4/6 (CDK-4/6) pathway. Brain metastasis, however, remains a thorn in the flesh, leading to morbidity, neuro-cognitive decline, and interruptions in the management of systemic disease...

Transplantation of embryonic stem cells (ESCs) is a promising therapeutic approach for the treatment of neurodegenerative diseases. However, ESCs are not usable clinically due to immunological and ethical limitations. The identification of an alternative safe cell source opens novel options via autologous transplantation in neuro-regeneration circumventing these problems. Here, we examined the neurogenic capacity of embryonic stem-like cells (ES-like cells) derived from the testis using neural growth factor inducers and utilized them to generate functional mature neurons...

A combined approach in spinal cord injury (SCI) therapy is the modulation of the cellular and molecular processes involved in glial scarring. Aldaynoglial cells are neural cell precursors with a high capacity to differentiate into neurons, promote axonal growth, wrapping and myelination of resident neurons. These important characteristics of aldaynoglia can be combined with specific inhibition of the RhoGTPase activity in astroglia and microglia that cause reduction of glial proliferation, retraction of glial cell processes and myelin production by oligodendrocytes...
