REVIEW
Eric M L Williamson, Joseph R Berger
Progressive multifocal leukoencephalopathy (PML) is a rare, but serious, complication encountered in patients treated with a select number of disease-modifying therapies (DMTs) utilized in treating multiple sclerosis (MS). PML results from a viral infection in the brain for which the only demonstrated effective therapy is restoring the perturbed immune system-typically achieved in the patient with MS by removing the offending therapeutic agent or, in the case of HIV-associated PML, treatment with highly active antiretroviral therapies...

Progressive multifocal leukoencephalopathy (PML) is a demyelinating disease caused by the JC virus, a polyomavirus that can be reactivated under certain immunosuppressive conditions, such as AIDS, immunomodulatory therapy, and haematological malignancies. However, a few cases of immunocompetent patients have been reported in which no immunodeficiency was present. We describe the case of an 83-year-old immunocompetent man who presented with severe cerebellar symptoms with an MRI scan suggestive of severe demyelinating disease...

Progressive multifocal leukoencephalopathy (PML) is an opportunistic infection of the central nervous system caused by JC virus. Only ten cases of PML have been reported so far in liver transplant recipients. We present a case of liver posttransplantation PML with characteristic clinical and brain MRI findings, but with an atypical late onset, developed 11 years after transplantation and after single-drug, long-term (8 years), and low-dose (750 mg twice a day) immunosuppression with mycophenolate mofetil (MMF)...

At the end of 2016, dimethyl fumarate (DMF) was approved as the sixth disease-modifying drug for multiple sclerosis by the Pharmaceuticals and Medical Devices Agency of Japan. Two randomized, placebo-controlled, phase III studies (DEFINE and CONFIRM) showed beneficial effects in patients in Western countries, with relapsing-remitting multiple sclerosis (RRMS). Some of the benefits included a decreased annual relapse rate, inhibition of disease activity (shown using brain magnetic resonance imaging), and a decreased proportion of patients with confirmed disease progression...

Specific protein-metal interactions (PMIs) fulfill essential functions in cells and organic bodies, and activation of these functions in vivo are mostly modulated by the complex environmental factors, including pH value, small biomolecules, and salts. Specifically, the role of salts in promoting specific PMIs and their competition among various metals has remained untapped mainly due to the difficulty to distinguish nonspecific PMIs from specific PMIs by classic spectroscopic techniques. Herein, we report Hofmeister salts differentially promote the specific PMIs by combining nanoelectrospray ionization mass spectrometry and spectroscopic techniques (fluorescence measurement and circular dichroism)...

Progressive multifocal leukoencephalopathy (PML) is an opportunistic viral infection of the central nervous system caused by the reactivation of John Cunningham virus (JCV) in immunocompromised patients, most commonly in human immunodeficiency virus (HIV) infection, and less commonly in those receiving various immunosuppressive regimens. Prognosis of untreated PML is grave and the mainstay of treatment is the reversal of immunosuppression, usually by institution of antiretroviral drugs in HIV patients and cessation of immunosuppressive therapies in others...

The survival of motor neuron (SMN) protein plays an essential role in the biogenesis of spliceosomal snRNPs and the molecular assembly of Cajal bodies (CBs). Deletion of or mutations in the SMN1 gene cause spinal muscular atrophy (SMA) with degeneration and loss of motor neurons. Reduced SMN levels in SMA lead to deficient snRNP biogenesis with consequent splicing pathology. Here, we demonstrate that SMN is a novel and specific target of the acetyltransferase CBP (CREB-binding protein). Furthermore, we identify lysine (K) 119 as the main acetylation site in SMN...

Acute promyelocytic leukemia (APL) is one of the most life-threatening hematological malignancies. Defects in the cell growth and apoptotic pathways are responsible for both disease pathogenesis and treatment resistance. Therefore, pro-apoptotic agents are potential candidates for APL treatment. Kaempferol is a flavonoid with antioxidant and anti-tumor properties. This study was designed to investigate the cytotoxic, pro-apoptotic and differentiation-inducing effects of kaempferol on HL-60 and NB4 leukemia cells...

Neuronal intranuclear hyaline inclusion disease (NIHID) is a neurodegenerative disorder characterized by the presence of eosinophilic nuclear inclusions (NIs) in diverse cell lines in systemic organs. Adult-onset NIHID typically manifests with dementia associated with leukoencephalopathy. The detection of NIs in skin biopsies is useful for an antemortem diagnosis. A previous analysis suggested that NIs in NIHID originated from nuclear bodies (NBs), an important nuclear domain related to the ubiquitin-p62-mediated protein degradation system...

Barry A Singer
Natalizumab, a monoclonal antibody that blocks lymphocyte infiltration in the central nervous system, is a valuable tool in the treatment of relapsing forms of multiple sclerosis (MS). In a phase III clinical trial comparing natalizumab with placebo over 2 years, natalizumab reduced annualized relapse rate by 68%, 12-week confirmed disability progression by 42%, and reduced contrast-enhancing lesions by 92%. In post hoc analyses, natalizumab treatment was associated with 37% of patients achieving no evidence of disease activity (versus 7% on placebo) and 30% achieving sustained disability improvement (versus 19% on placebo)...

Percutaneous edge-to-edge mitral valve repair (PMVR) is widely used for selected, high-risk patients with severe mitral valve regurgitation (MR). This report describes a case of 81-year-old woman presenting with severe and highly symptomatic mitral valve regurgitation (MR) caused by a flail of the posterior mitral valve leaflet (PML). PMVR turned out to be challenging in this patient because of a stenosis and tortuosity of both iliac veins as well as sclerosis of the interatrial septum, precluding the vascular and left atrial access by standard methods, respectively...

Promyelocytic leukemia protein (PML) nuclear bodies (NBs), which are sub-nuclear protein structures, are involved in a variety of important cellular functions. PML NBs are assembled by PML isoforms, and SUMO-SIM interactions are critically involved in this process. PML isoforms contain a common N-terminal region and a variable C-terminus. However, the contribution of the C-terminal regions to PML-NB formation remains poorly defined. Here, using high-resolution microscopy, we show that mutation of the SIM distinctively influences the structure of NBs formed by each individual PML isoform, with that of PML-III/-V minimally changed and PML-I/-IV dramatically impaired...

Multiple Sclerosis (MS) treatment with natalizumab is associated with Progressive Multifocal Leukoencephalopathy (PML). The risk of PML being related to the anti-JCV antibody index is well established, but there is less known about seroconversion rates in natalizumab-treated patients and longitudinal variation in the anti-JCV antibody index. Our objective was to assess anti-JCV antibody prevalence in an MS population and to evaluate the evolution of the anti-JCV antibody index in natalizumab-treated patients...

INTRODUCTION: Among disease-modifying treatments for multiple sclerosis, natalizumab (NTZ) is highly effective, well tolerated and generally safe. Major concerns regard the risk of developing progressive multifocal leukoencephalopathy (PML), and the occurrence of rebounds or disease activity after its discontinuation. The aim of this study was to explore the efficacy of dimethyl fumarate (DMF) in preventing disease reactivation after NTZ discontinuation. METHODS: Thirty-nine patients with relapsing remitting multiple sclerosis, at high risk of PML, were switched from NTZ to DMF and underwent neurological and 3T MRI monitoring for 2 years...

B lymphocyte-induced maturation protein-1 (Blimp-1) ensures B-cell differentiation into the plasma cell stage, and its instability constitutes a crucial oncogenic element in certain aggressive cases of activated B cell-like diffuse large B-cell lymphoma (ABC-DLBCL). However, the underlying degradation mechanisms and their possible therapeutic relevance remain unexplored. Here, we show that N-terminal misfolding mutations in ABC-DLBCL render Blimp-1 protein susceptible to proteasome-mediated degradation but spare its transcription-regulating activity...

To determine the association between BK polyomavirus (BKPyV) types 1 and 4 capsid antibody and natalizumab-associated progressive multifocal leukoencephalopathy (PML) in patients with multiple sclerosis (MS), serum samples were obtained from 10 natalizumab-associated PML cases and 130 control MS patients treated with natalizumab, and 82 control MS patients never exposed to natalizumab. In a sex- and age-adjusted regression model, BKPyV serotype 1 antibody levels were significantly higher in natalizumab-treated controls (p = 0...

Sensitive biomarkers are needed to better manage multiple sclerosis (MS) patients for natalizumab (NTZ)-associated risk of progressive multifocal leukoencephalopathy (PML). A currently used risk stratification algorithm, mainly based on JC polyomavirus (JCPyV) serology, has not led to a reduction of PML incidence. Therefore, this study was designed to evaluate the presence and prevalence of JCPyV miRNAs in plasma of NTZ-treated MS patients, and to explore their biomarker potential for NTZ-associated PML risk assessment...

We present the case of an HIV-2-infected patient who developed progressive multifocal leukoencephalopathy (PML) in the setting of immune reconstitution inflammatory syndrome (IRIS) presenting as Bell's palsy. The brain MRI showed a single lesion in the facial colliculus considered initially to be ischemic in nature. This case report should alert clinicians that PML can occur in the setting of HIV-2 infection. It also illustrates the difficulty of establishing the diagnosis of PML.
