A major concern associated with ZIKV infection is the increased incidence of microcephaly with frequent calcifications in infants born from infected mothers. To date, postmortem analysis of the central nervous system (CNS) in congenital infection is limited to individual reports or small series. We report a comprehensive neuropathological study in ten newborn babies infected with ZIKV during pregnancy, including the spinal cords and dorsal root ganglia (DRG), and also muscle, pituitaries, eye, systemic organs, and placentas...

Calcitonin gene-related peptide (CGRP) is a 37-amino acid peptide found primarily in the C and Aδ sensory fibers arising from the dorsal root and trigeminal ganglia, as well as the central nervous system. Calcitonin gene-related peptide was found to play important roles in cardiovascular, digestive, and sensory functions. Although the vasodilatory properties of CGRP are well documented, its somatosensory function regarding modulation of neuronal sensitization and of enhanced pain has received considerable attention recently...

REVIEW
Anna Gryglas, Robert Smigiel
Migraine and stroke are common, disabling neurologic disorders, with a high socioeconomic burden. A link between them has been proposed years ago, and various theories have been proposed to explain this bidirectional relation. However, the precise causes remain unclear. We briefly summarize existing hypotheses of this correlation seeking for recommendations for stroke prevention in migraineurs, if any exist. Among the strongest suggested theories of migraine-stroke association are cortical spreading depression, endovascular dysfunction, vasoconstriction, neurogenic inflammation, hypercoagulability, increased prevalence of vascular risk factors, shared genetic defects, cervical artery dissection, and patent foramen ovale...

BACKGROUND: In acupuncture practice, the most important step is to confirm the location of a sensitized acupoint which reflects a diagnosis and can be stimulated with a specialized needle to treat the disease. Abnormal symptoms such as hyperalgesia or allodynia at the sensitized acupoints in patients with visceral disorders are considered to be in relation with referred pain and neurogenic inflammation. Yet, limited study has investigated the cutaneous neurochemical changes of the sensitized acuponits...

The present study aimed to determine whether there is an association between abnormalities in enteroendocrine cells in dextran sulfate sodium (DSS)‑induced colitis and the clonogenic and/or proliferative activities of stem cells. A total of 48 male Wistar rats were divided into four groups. Animals in the control group were provided with normal drinking water, whereas DSS colitis was induced in the remaining three groups. The rats with DSS‑induced colitis were randomized into the following three groups: i) DSS group, which received 0...

The correlation between the pathophysiologies of diabetic foot ulcerations is yet to be established and improved treatments are still required. We propose a strategy that directs inflammation, neo-vascularization and neo-innervation of diabetic wounds. Aiming to potentiate a relevant secretome for nerve regeneration, stem cells were pre-cultured in hyaluronic acid-based spongy-like hydrogels under neurogenic/standard media prior transplantation into diabetic mice full-thickness wounds. Acellular spongy-like hydrogels and empty wounds were used as controls...

Increasing evidence suggests that respiratory syncytial virus (RSV) infection during the early life is an important risk factor for the development of asthma. RSV infection is associated with neurogenic inflammation in the airways along with the increased expression of nerve growth factor (NGF). However, the role of NGF in RSV infection is not clear. In this study, we infected the rat with RSV and treated these animals with anti-NGF neutralization antibody. We found that anti-NGF treatment significantly alleviated the lung inflammation as evidenced by decreased inflammatory infiltration and decreased airway resistance...

Toluene diisocyanate (TDI) is the most important cause of occupational asthma (OA), and various pathogenic mechanisms have been suggested. Of these mechanisms, neurogenic inflammation is an important inducer of airway inflammation. Transient receptor potential melastatin 8 (TRPM8) is a well-established cold-sensing cation channel that is expressed in both neuronal cells and bronchial epithelial cells. A recent genome-wide association study of TDI-exposed workers found a significant association between the phenotype of TDI-induced OA and the single-nucleotide polymorphism rs10803666, which has been mapped to the TRPM8 gene...

BACKGROUND: Neuropeptides, such as substance P (SP), have long been seen as mediators of widespread, continuous airway inflammation, a process known as neurogenic inflammation. However, this has been difficult to demonstrate clinically, suggesting an alternative role for these signaling molecules. OBJECTIVES: To examine the role of SP in nasal infection, by assessing the release of SP in response to viral stimulation and characterizing the effects of SP on innate immunity, the latter reflected in changes in local Toll-like receptor (TLR) expression...

Neurotrophins (NTs) have been implicated in generation and modulation of nociceptive pathways. Change in NTs levels is associated with painful conditions and neurological diseases such as migraine. Currently, it is generally recognized that migraine headaches result from the activation and sensitization of trigeminal sensory afferent fibers leading to neuropeptides release such as calcitonin gene-related peptide (CGRP) and substance P (SP). This triggers an inflammatory cascade causing a neurogenic inflammation...

The neuropeptide substance P (SP) is an important mediator of neurogenic inflammation within the central and peripheral nervous systems. SP has been shown to induce the expression of pro-inflammatory cytokines implicated in the pathogenesis of several disorders of the human brain via the neurokinin-1 receptor (NK-1R). Ketamine, an intravenous anesthetic agent, functions as a competitive antagonist of the excitatory neurotransmission N-methyl-D‑aspartate (NMDA) receptor, and also antagonizes the NK-1R by interfering with the binding of SP...

ETHNOPHARMACOLOGICAL RELEVANCE: Ipomoea pes-caprae is known as bayhops, beach morning glory or goat's foot, and in Brazil as salsa-de-praia. Its leaves are used in worldwide folk medicine for the relief of jellyfish-stings symptoms. The literature only reports the anti-inflammatory and neutralizing effects of a nonpolar plant derived, without validating the popular use or exploring the mechanism of action. AIM OF THE STUDY: This study aimed to evaluate and validate the topical effects of a semisolid containing hydroethanolic extract obtained from the aerial parts of I...

Psoriasis is a chronic inflammatory skin disease with a prevalence of 2-3 %. It appears to result from a combination of genetic and environmental factors, but the precise pathogenesis is still unknown. Neurogenic inflammation is involved in psoriasis pathogenesis as well, but the role of neurogenic factors is currently unclear. Molecular studies often involve material obtained from patients. However, many questions and especially experimental manipulations are not suited for study in humans. Imiquimod application on mouse skin leads to immune cell infiltration, inflammation with intense redness, epidermal thickening, and scaling that jointly greatly resembles human psoriasis...

The fibronectin type III domain containing 5 (FNDC5)/Irisin, a novel energy-regulating hormone, is associated with lipid and carbohydrate metabolism. It is produced in low amounts by normal hepatic tissue, while in human hepatocellular carcinoma (HCC), in which aberrant de novo lipogenesis (DNL) occurs, the hepatic expression of FNDC5/Irisin is still unknown. The gene expression of FNDC5/Irisin, associated to key regulators of DNL, inflammation and cancer progression was evaluated in liver tissue of 18 patients with HCC undergoing liver transplantation and of 18 deceased donors...

Stroke is a leading cause of death and disability worldwide with no treatment for the chronic phase available. Interestingly, an endogenous repair program comprising inflammation and neurogenesis is known to modulate stroke outcome. Several studies have shown that neurogenesis decreases with age but the therapeutic importance of endogenous neurogenesis for recovery from cerebral diseases has been indicated as its ablation leads to stroke aggravation and worsened outcome. A detailed characterization of the neurogenic response after stroke related to ageing would help to develop novel and targeted therapies...

Chronic cough is one of the most common clinical problems and it may be secondary to different stimuli and diseases, including low-level physical and chemical stimulation of the esophageal-bronchial reflex, suggestive of cough-reflex hyperresponsiveness, in patients with gastroesophageal reflux; however, it is still debated whether gastroesophageal reflux could induce airway inflammation and acidification. The aim of this study was to investigate airway pH and cysteynil-leukotrienes (Cys-LTs) concentration (a marker of airway inflammation) in exhaled breath condensate (EBC)...

Nerve growth factor (NGF) is involved in several joint diseases. It participates in nociception and neurogenic inflammation and its concentrations increase in synovial fluid and tissue from arthritis. However, data about its role in articular cartilage are scant and conflicting. This study analysed effects of different NGF concentrations on cultured human chondrocytes by evaluating cell proliferation, cell phenotype, and gene expression. The MTT test excluded an influence on cell viability. Alcian blue and S100 staining demonstrated that NGF may induce de-differentiation of the chondrocyte phenotype...

Byrsonima verbascifolia (Malpighiaceae), commonly known as 'murici', is used in folk medicine, for example, in the treatment of inflammation. The anti-inflammatory activity of the butanolic fraction of B. verbascifolia leaves (BvBF) was previously reported by our group, and the present study was designed to evaluate their antinociceptive effects. BvBF (25, 50, and 100 mg/kg) administered intraperitoneally (i.p.) inhibited acetic acid induced abdominal writhing. In the formalin test, BvBF (10, 30 and 100 mg/kg, i...
