BACKGROUND: Atypical chemokine receptor 3 (ACKR3, synonym CXCR7) is increasingly considered relevant in neuroinflammatory conditions, in which its upregulation contributes to compromised endothelial barrier function and may ultimately allow inflammatory brain injury. While an impact of ACKR3 has been recognized in several neurological autoimmune diseases, neuroinflammation may also result from infectious agents, including Ureaplasma species (spp.). Although commonly regarded as commensals of the adult urogenital tract, Ureaplasma spp...

The recognition of the antibody-mediated encephalitis as a separate entity among the immune disorders of the central nervous system was one of the greatest breakthroughs of the last two decades in neurology. Unlike viral or tumor-related encephalitis, the antibody-mediated form has a good response to immunotherapy, which gives a special clinical importance to the discovery. Anti-N-methyl-D-aspartate receptor (anti-NMDAR) encephalitis is one of the first fully characterized antibody-mediated encephalitises. This article attempts to summarize the clinical features of this complex neuropsychiatric disorder with the aim to help its early recognition and to report the clinical course and the outcome of our six seropositive anti-NMDAR cases...

It was demonstrated that isoflavones can cross the blood-brain barrier, making them desirable candidate agents for the prevention of neurological symptoms. 8-Hydroxydaidzein (8-OHD, 4',7,8-trihydoxyisoflavone) is an isoflavone found only in fermented soy food. Current results showed that 8-OHD inhibited LPS-stimulated production of nitric oxide (NO) and proinflammatory cytokines, such as tumor necrosis factor (TNF)-α and interleukin (IL)-6, by inhibiting gene expression in BV2 microglial cells. Moreover, 8-OHD markedly quenched reactive oxygen species (ROS) and activated NF-E2-related factor 2 (Nrf2) so as to upregulate expression of Phase II enzymes, including heme oxygenase (HO)-1, NAD(P)H quinone dehydrogenase 1 (NQO1), and the modifier subunit of glutamate cysteine ligase (GCLM)...

Adoptive T-cell therapy, incorporating engineered T cell receptors (TCRs) or chimeric antigen receptors (CARs), target tumor antigens with high affinity and specificity. To increase the potency of adoptively transferred T cells, patients are conditioned with lymphodepleting chemotherapy regimens prior to adoptive T-cell transfer (ACT), and data suggest that fludarabine is an important component of an effective regimen. In a recent clinical trial using CAR-T cells engineered to target the CD19 B-cell antigen to treat acute lymphoblastic leukemia, JCAR-015 (NCT02535364), two patient deaths due to cerebral edema led to trial suspension...

Brain diseases including neurological disorders and tumors remain under treated due to the challenge to access the brain, and blood-brain barrier (BBB) restricting drug delivery which, also profoundly limits the development of pharmacological treatment. Focused ultrasound (FUS) with microbubbles is the sole method to open the BBB noninvasively, locally, and transiently and facilitate drug delivery, while translation to the clinic is challenging due to long procedure, targeting limitations, or invasiveness of current systems...

BACKGROUND: Headache, like dizziness, is one of the more common presenting complaints in outpatient care and in the emergency room. More than 200 varieties of headache have been described, and the false impression may arise that the diagnosis and treatment of these syndromes is a highly challenging task. METHODS: This review is based on pertinent articles retrieved by a selective search in PubMed. RESULTS: In primary headache, the headache is not a symptom but a disease in its own right...

BACKGROUND: Traumatic brain injury (TBI) begins with the application of mechanical force to the head or brain, which initiates systemic and cellular processes that are hallmarks of the disease. The pathological cascade of secondary injury processes, including inflammation, can exacerbate brain injury-induced morbidities and thus represents a plausible target for pharmaceutical therapies. We have pioneered research on post-traumatic sleep, identifying that injury-induced sleep lasting for 6 h in brain-injured mice coincides with increased cortical levels of inflammatory cytokines, including tumor necrosis factor (TNF)...

Background: Corticosteroids are the mainstay of treatment for peritumor edema but are often associated with significant side effects. Therapies that can reduce corticosteroid use would potentially be of significant benefit to patients. However, currently there are no standardized endpoints evaluating corticosteroid use in neuro-oncology clinical trials. Methods: The Response Assessment in Neuro-Oncology (RANO) Working Group has developed consensus recommendations for endpoints evaluating corticosteroid use in clinical trials in both adults and children with brain tumors...

Paraneoplastic syndromes involving the visual system are a heterogeneous group of disorders occurring in the setting of systemic malignancy. They are unrelated to local tumor invasion or metastasis and unexplained by nutritional, metabolic, infectious or iatrogenic causes. The presence of antibodies may aid in the diagnosis of a paraneoplastic syndrome, although this is not an absolute requirement. Chorioretinal involvement is seen in CAR (cancer-associated retinopathy) syndrome, MAR (melanoma-associated retinopathy) syndrome, paraneoplastic vitelliform maculopathy, and bilateral diffuse uveal melanocytic proliferation...

Dear Editor, Tuberous sclerosis (TS) is an autosomal dominant multisystem disease, which occurs due to genetically determined hyperplasia of ectodermal and mesodermal cells. Clinical manifestations present on the skin and in the nervous system, kidneys, heart, and other organs. Recent studies estimate the incidence of TS at 1/6000 to 1/10,000 live births, and a prevalence in the general population of approximately 1 in 20,000 (1). There are two different genetic loci responsible for TS: 9q34 (TSC1-hamartin) and 16p13...

A 64-year-old man was admitted with acute onset disturbed consciousness. Cerebrospinal fluid analysis revealed pleocytosis and elevated protein, with negative cultures and PCR. Serum antibodies for autoimmune encephalitis were also negative. Brain magnetic resonance imaging (MRI) was unremarkable, but whole-body CT scan showed a tumor in the left lower lung lobe. Bronchial brush cytology demonstrated clusters of malignant cells, and 18 F-fluorodeoxyglucose positron emission tomography showed multiple lesions and increased uptake in the lung tumor...

Vitamin C deficiency is anecdotal in developed countries, mainly associated with underling clinical morbidities as autism or neurological impairment. Chronic insufficient dietary supply is responsible for vascular fragility and impaired bone formation, resulting in gingival bleeding, petechial lesions, articular and bone pain or limb swelling. Children may present anorexia, irritability, failure to thrive, limping or refusal to walk. Accordingly, pediatric scurvy is frequently misdiagnosed with osteomyelitis, septic arthritis, bone and soft tissue tumor, leukemia, bleeding disorders, and rheumatologic conditions...

The exact cause of Alzheimer's disease (AD) is still unknown, but the deposition of amyloid-β (Aβ) plaques and chronic inflammation indicates that immune disturbances are involved in AD pathogenesis. Recent genetic studies have revealed that many candidate genes are expressed in both microglia and myeloid cells which infiltrate into the AD brains. Invading myeloid cells controls the functions of resident microglia in pathological conditions, such as AD pathology. AD is a neurologic disease with inflammatory component where the immune system is not able to eliminate the perpetrator, while, concurrently, it should prevent neuronal injuries induced by inflammation...

Bifenthrin (BF) is a synthetic pyrethroid pesticide widely used in several countries to manage insect pests on diverse agricultural crops. Growing evidence indicates that BF exposure is associated with an increased risk of developing neurodegenerative disorders. However, the mechanisms by which BF induces neurological and anxiety alterations in the frontal cortex and striatum are not well known. The present in vivo study was carried out to determine whether reactive oxygen species (ROS)-mediated oxidative stress (OS) and neuroinflammation are involved in such alterations...
