In central nervous system (CNS) demyelinating disorders, such as multiple sclerosis (MS), neuromyelitis optica (NMO) and related NMO-spectrum disorders (NMO-SD), a pathogenic role for antibodies is primarily projected into enhancing ongoing CNS inflammation by directly binding to target antigens within the CNS. This scenario is supported at least in part, by antibodies in conjunction with compl...

Background: Central Nervous System (CNS) relapse in acute lymphoblastic leukemia was significantly decreased due to the use of new chemotherapyeutic agents, Intrathecal chemotherapy and cranial irradiation. The purpose of this study was to compare the effectiveness of intrathecal (IT) CNS chemotherapy alone versus combination of IT chemotherapy with cranial irradiation for prevention of CNS rel...

While combination antiretroviral therapy (CART) has decreased the incidence of HIV-associated dementia, the severest form of HIV-associated neurocognitive disorders (HAND), mild neurocognitive disorder and asymptomatic neurocognitive impairment continue to persist, and there is evidence that neurocognitive deficits present even in acute HIV infection. Recent studies demonstrate that CART regime...

Antibodies to myelin oligodendrocyte glycoprotein (MOG-IgG) or aquaporin 4 (AQP4-IgG) are associated with CNS inflammatory disorders. We directly compared MOG35-55-induced experimental autoimmune encephalomyelitis exacerbated by MOG- and AQP4-IgG (versus isotype IgG, Iso-IgG). Disease severity was highest after MOG-IgG application. administration increased disease incidence Iso-IgG. Inflammator...

Myelin-Oligodendrocyte Glycoprotein (MOG) is an adhesive molecule responsible for myelin sheath structural integrity and maintenance. Patients with spectrum of inflammatory demyelinating disease particularly in central nervous system are reported to have antibodies against this protein. Diseases such as multiple sclerosis, clinically isolated syndrome, neuro-myelitis optica (NMO) spectrum disor...

Acute brain injuries cause rapid cell death that activates bidirectional crosstalk between the injured brain and the immune system. In the acute phase, the damaged CNS activates resident and circulating immune cells via the local and systemic release of soluble mediators. This early immune activation is necessary to confine the injured tissue and foster the clearance of cellular debris, thus br...

Tumour necrosis factor (TNF-alpha) concentrations were determined in the CSF from 42 HIV-infected patients, with or without CNS involvement. In addition, 14 subjects with various neurological disorders but without HIV antibodies were included as controls. Raised CSF concentrations of TNF-alpha (greater than 40 ng/l) were detected both in patients with AIDS dementia complex (ADC) (6/9) and with ...

Allopregnanolone is an endogenous neurosteroid that acts in a rapid non-genomic manner to enhance the function of GABAA receptor (GABAAR), major inhibitory mammalian central nervous system (CNS). Consequently, allopregnanolone elicits anxiolytic, antidepressant, anticonvulsant, analgesic and sedative effects. Endogenous influences neural inhibition behaviour, with perturbed levels implicated de...

PURPOSE OF REVIEW In the past decade, primary and secondary central nervous system (CNS) vasculitides have been more commonly diagnosed and recognized than previously. With the increasing awareness of these disorders, it is crucial for the treating physician to differentiate between causes of CNS vasculitis and to recognize their marked clinical and pathophysiological heterogeneity. This review...
