Glaucoma is a complex neurodegenerative disease with many clinical subtypes. Some of its rare forms include pigmentary glaucoma, uveitic glaucoma and congenital glaucoma. While they all share common features of progressive retinal ganglion cell (RGC) loss, optic nerve damage and corresponding visual field loss, the exact mechanisms underlying glaucomatous neuron loss are not clear. This has largely hindered the development of a real cure for this disease. Elevated intraocular pressure (IOP) is a known major risk factor of glaucoma; however, progressive degeneration of RGCs and axons can also be found in patients with a normal IOP, i...

The thymus is innervated by sympathetic/parasympathetic nerve fibers from the peripheral nervous system (PNS), suggesting a neural regulation of thymic function including T-cell development. Despite some published studies, data on the innervation and nerve-immune interaction inside the thymus remain limited. In the present study, we used immunofluorescent staining of glial fibrillary acidic protein (GFAP) coupled with confocal microscopy/three-dimensional (3D) reconstruction to reveal the distribution of non-myelinating Schwann cells (NMSC) and their interactions with immune cells inside mouse thymus...

The neural regulation of organs can be categorized as systemic or local. Whereas systemic regulation by the hypothalamus-pituitary-adrenal gland-mediated release of steroid hormones has been well studied, the mechanisms for local regulation have only recently emerged. Two types of local neural regulation are known, the gateway reflex and the inflammatory reflex. The gateway reflex describes a mechanism that converts regional neural stimulations into inflammatory outputs by changing the state of specific blood vessels...

Multiple sclerosis (MS) is a chronic immune-mediated disease of the central nervous system (CNS) characterized by neuroinflammation, neurodegeneration and impaired repair mechanisms that lead to neurological disability. The crux of MS is the patient's own immune cells attacking self-antigens in the CNS, namely the myelin sheath that protects nerve cells of the brain and spinal cord. Restoring antigen-specific tolerance via therapeutic vaccination is an innovative and exciting approach in MS therapy. Indeed, leveraging the body's attempt to prevent autoimmunity, i...

BACKGROUND: Immune checkpoint inhibitors (ICIs) are a promising class of anticancer drugs associated with immune-related adverse events (IRAEs). In registration studies of selected cancer populations, neurologic IRAEs were rare. Post-marketing experience describing their prevalence in clinical practice continues to be reported. METHODS: A retrospective cohort of patients treated at our institution with ICIs from 2005 to 2017 was identified. Patients with new neurologic ICD codes documented during or after ICI treatment were enrolled...

Transplantation of neural stem cells (NSCs) holds great potential for the treatment of spinal cord injury (SCI). However, transplanted NSCs poorly survive in the SCI environment. We injected NSCs into tibial nerve and transplanted tibial nerve into a hemisected spinal cord and investigated the effects of lithium chloride (LiCl) on the survival of spinal neurons, axonal regeneration, and functional recovery. Our results show that most of the transplanted NSCs expressed glial fibrillary acidic protein, while there was no obvious expression of nestin, neuronal nuclei, or acetyltransferase found in NSCs...

Transferrin, a member of the iron binding superfamily protein, plays an extremely important role in the transport of iron in the biological process of cells. The result of preliminary proteomic study on E. sinensis hemocytes infected Spiroplasma eriocheiris showed the expression of transferrin (EsTF) and ferrin (EsFe) significantly changed. In addition, other reports have confirmed that transferrin, ferritin and iron are involved in the immune response of hosts. In order to validate the immune function of EsTF, the whole length of EsTF was successfully amplified by the gene cloning and RACE technique...

Prostaglandin (PG) E2 is an important lipid mediator that is involved in several pathophysiological processes contributing to fever, inflammation and pain. Previous studies have shown that early and continuous application of non-steroidal anti-inflammatory drugs significantly reduces pain behavior in the spared nerve injury (SNI) model for trauma-induced neuropathic pain. However, the role of PGE2 and its receptors in the development and maintenance of neuropathic pain is incompletely understood, but may help inform strategies for pain management...

Shanghuo(excessive internal heat) is a special organic state based on the concept of traditional Chinese medicine(TCM), commonly known as the abnormal heating syndrome of body in folks. With the acceleration of modern life rhythm and the increase of the social competition pressure, emotional stress has become an important cause for the spread of Shanghuo symptoms. What's more, Shanghuo can impact the body physiological functions to cause the onset, recurrence and progression of common diseases, harming the health of the body...

REVIEW
Chikara Abe, Tsuyoshi Inoue
Neuroimmune communication, the connection between the autonomic regulatory pathway and immune cells, has been implicated in the regulation of immune function and inflammation. The role of afferents (vagal afferent and somatic sensory nerves) and efferents (autonomic nervous and hypothalamic-pituitary-adrenal systems) in the inflammatory reflex has been well studied; however, the central pathway remains unknown. C1 neurons include both catecholaminergic and glutamatergic neurons, which are located in the rostral ventrolateral medulla...

This article reports nine cases of neurological disease in brown layer pullets that occur in various European countries between 2015 and 2018. In all cases, the onset of neurological clinical signs was at 4-8 weeks of age and they lasted up to 22 weeks of age. Enlargement of peripheral nerves was the main lesion observed in all cases. Histopathological evaluation of nerves revealed edema with moderate to severe infiltration of plasma cells. Marek's disease (MD) was ruled out by real time PCR as none of the evaluated tissues had high load of oncogenic MD virus (MDV) DNA, characteristics of MD...

PURPOSE: Merkel cell carcinoma (MCC) is a malignant neuroendocrine skin tumor with known viral association. The microenvironment and its interaction with the tumor via the programmed cell death protein 1 (PD-1) pathway are crucial for response to anti-PD-1/anti-PD-L1 treatments. However, not all patients respond, which is suggestive of additional mechanisms for tumor growth and/or persistence. We previously detected tropomyosin receptor kinase A (TrkA) expression on MCC tumor cells and, therefore, gained interest in the expression of its ligand nerve growth factor (NGF)...

Skull base osteomyelitis can involve the jugular foramen and its associated cranial nerves resulting in specific clinical syndromes. The Collet-Sicard syndrome describes the clinical manifestations of palsies involving cranial nerves IX, X, XI, and XII. We present a rare atypical case of skull base osteomyelitis originating from infection of the middle ear and causing the Collet-Sicard syndrome. Caused by Pseudomonas aeruginosa and Klebsiella pneumoniae , this occurred in an elderly diabetic man subsequent to retention of a cotton swab in an ear with chronic suppurative otitis media...

Herpes zoster (HZ/shingles) is the clinical manifestation of varicella zoster virus (VZV) reactivation. HZ typically develops as people age due to decreased cell-mediated immunity. However, the importance of antibodies for immunity against HZ prevention remains to be understood. The goal of this study was to examine the breadth and functionality of VZV-specific antibodies after vaccination with a live attenuated HZ vaccine (Zostavax). Direct enumeration of VZV-specific antibody secreting cells (ASC) via ELISPOT showed that Zostavax can induce both IgG and IgA ASCs seven days after vaccination, but not IgM ASCs...

Nerve growth factor, the prototype of a family of neurotrophins, elicits differentiation and survival of peripheral and central neuronal cells. Although its neural mechanisms have been studied extensively, relatively little is known about the transcriptional regulation governing its effects. We have previously observed that in primary cultures of rat hippocampal neurons treatment with nerve growth factor for 72 hr increases neurite outgrowth and cell survival. To obtain a comprehensive view of the underlying transcriptional program, we performed whole-genome expression analysis by microarray technology...

The nervous system maintains physiological homeostasis through reflex pathways that modulate organ function. This process begins when changes in the internal milieu (e.g., blood pressure, temperature, or pH) activate visceral sensory neurons that transmit action potentials along the vagus nerve to the brainstem. IL-1β and TNF, inflammatory cytokines produced by immune cells during infection and injury, and other inflammatory mediators have been implicated in activating sensory action potentials in the vagus nerve...

BACKGROUND: Hepatitis C virus (HCV)-associated mixed cryoglobulinaemia is the manifestation of an inflammation of small and medium-sized vessels produced by a pathogenic IgM with rheumatoid factor activity generated by an expansion of B-cells. The immune complexes formed precipitate mainly in the skin, joints, kidneys or peripheral nerve fibres. Current therapeutic approaches are aimed at elimination of HCV infection, removal of cryoglobulins and also of the B-cell clonal expansions. The optimal treatment for it has not been established...

As with castles, tumor cells are fortified by surrounding non-malignant cells, such as cancer-associated fibroblasts, immune cells, but also nerve fibers and extracellular matrix. In most cancers, this fortification creates a considerable solid pressure which limits oxygen and nutrient delivery to the tumor cells and causes a hypoxic and nutritional stress. Consequently, tumor cells have to adapt their metabolism to survive and proliferate in this harsh microenvironment. To satisfy their need in energy and biomass, tumor cells develop new capacities to benefit from metabolites of the microenvironment, either by their uptake through the macropinocytosis process or through metabolite transporters, or by a cross-talk with stromal cells and capture of extracellular vesicles that are released by the neighboring cells...

Chronic prostatitis is a common male disease with a high incidence rate and a serious impact on the patients' quality of life. The pathogenesis of chronic prostatitis remains unclear though it is considered to be possibly related to infection, inflammation, and abnormal pelvic nerve muscle activity. Recently, a growing number of studies have reported immune imbalance and changes of inflammatory cytokines in patients with chronic prostatitis as well as a close correlation of abnormal immune response with the occurrence of diseases, pelvic pain symptoms, mental symptoms, hyperalgesia, and so on...
