Tdp-43 Is Elevated In Plasma Neuronal-Derived Exosomes Of Patients With Alzheimer’S Disease, N. Zhang, D. Gu, M. Meng, M. L. Gordon

Journal Articles

© Copyright © 2020 Zhang, Gu, Meng and Gordon. Background: Recently, TDP-43 has been recognized as a common proteinopathy in the “oldest old” and a neuropathological comorbidity in patients with Alzheimer’s disease (AD). However, since it has a low concentration in cerebrospinal fluid, the presence of TDP-43 in AD is rarely investigated in vivo. Methods: Twenty-four patients with amyloid PET confirmed AD and 15 healthy controls (HCs) were included in this study. TDP-43 level in plasma neuronal-derived exosomes (NDEs) was measured by enzyme-linked immunosorbent assay. Results: TDP-43 level was elevated in patients with AD compared with HCs (median 1.08 ng/ml, …

Journal Articles

© 2020 The Authors Purpose: Multiple system atrophy (MSA) is an atypical parkinsonian syndrome and often difficult to discriminate clinically from progressive supranuclear palsy (PSP) and Parkinson's disease (PD) in early stages. Although a characteristic metabolic brain network has been reported for MSA, it is unknown whether this network can provide a clinically useful biomarker in different centers. This study was aimed to identify and cross-validate MSA-related brain network and assess its ability for differential diagnosis and clinical correlations in Chinese and American patient cohorts. Methods: We included 18F-FDG PET scans retrospectively from 128 clinically diagnosed parkinsonian patients (34 MSA, …

Nono Is A Novel Co-Factor Of Prdm1 And Regulates Inflammatory Response In Monocyte Derived-Dendritic Cells, K. Lee, S. H. Jang, H. Tian, S. J. Kim

Journal Articles

© Copyright © 2020 Lee, Jang, Tian and Kim. Proper expression of the transcription factor, Positive regulatory domain 1 (PRDM1), is required for maintaining homeostasis of human monocyte derived-dendritic cells (MO-DCs). The molecular mechanisms and gene targets of PRDM1 in B and T lymphocytes have been identified. However, the function of PRDM1 in dendritic cells (DCs) remains unclear. We investigate co-regulators of PRDM1 in MO-DCs identified by mass spectrometry (MS) and co-immunoprecipitation (Co-IP). Notably, non-POU domain-containing octamer-binding protein (NonO) was found to be a PRDM1 binding protein in the nucleus of MO-DCs. NonO is recruited to the PRDM1 binding site …

Ultrasound Powered Piezoelectric Neurostimulation Devices: A Commentary., T. Sun, J. Wright, T. Datta-Chaudhuri

Journal Articles

Conventional neurostimulation systems for preclinical research can be bulky and invasive due to the need for batteries or wired interfaces. Emerging as a new neural interface technique, ultrasound-powered piezoelectric neural stimulators work by converting ultrasound energy to electrical charge for neural stimulation. In addition to the benefits of wireless powering and miniaturization leading to less traumatic surgery, piezoelectric neural stimulators can also exhibit prolonged operational lifetimes for a long-term stable neural interface, and show promise for clinical translation. As one of first steps to demonstrate the value of ultrasound-powered piezoelectric neural interface, Li et al. developed a piezoelectric stimulator to …

In Utero Exposure To Endogenous Maternal Polyclonal Anti-Caspr2 Antibody Leads To Behavioral Abnormalities Resembling Autism Spectrum Disorder In Male Mice, C. Bagnall-Moreau, P. T. Huerta, D. Comoletti, A. La-Bella, R. Berlin, C. Zhao, B. T. Volpe, B. Diamond, L. Brimberg

Journal Articles

© 2020, The Author(s). The concept that exposure in utero to maternal anti-brain antibodies contributes to the development of autism spectrum disorders (ASD) has been entertained for over a decade. We determined that antibodies targeting Caspr2 are present at high frequency in mothers with brain-reactive serology and a child with ASD, and further demonstrated that exposure in utero to a monoclonal anti-Caspr2 antibody, derived from a mother of an ASD child, led to an-ASD like phenotype in male offspring. Now we propose a new model to study the effects of in utero exposure to anti-Caspr2 antibody. Dams immunized with the …

Sars-Cov-2 And Interferon Blockade, B. Diamond, B. T. Volpe, S. Vanpatten, Y. Al Abed

Journal Articles

© 2020, The Author(s). The response to viral infection generally includes an activation of the adaptive immune response to produce cytotoxic T cells and neutralizing antibodies. We propose that SARS-CoV-2 activates the innate immune system through the renin-angiotensin and kallikrein-bradykinin pathways, blocks interferon production and reduces an effective adaptive immune response. This model has therapeutic implications.

Pathophysiology And Pathology Of Acute Kidney Injury In Patients With Covid-19, J. H. Ng, V. Bijol, M. A. Sparks, M. E. Sise, H. Izzedine, K. D. Jhaveri

Journal Articles

© 2020 National Kidney Foundation, Inc. Acute kidney injury (AKI) is common among hospitalized patients with Coronavirus Infectious Disease 2019 (COVID-19), with the occurrence of AKI ranging from 0.5% to 80%. The variability in the occurrence of AKI has been attributed to the difference in geographic locations, race/ethnicity, and severity of illness. AKI among hospitalized patients is associated with increased length of stay and in-hospital deaths. Even patients with AKI who survive to hospital discharge are at risk of developing chronic kidney disease or end-stage kidney disease. An improved knowledge of the pathophysiology of AKI in COVID-19 is crucial to …

Alterations In Plasma Membrane Ion Channel Structures Stimulate Nlrp3 Inflammasome Activation In Apol1 Risk Milieu, A. Jha, V. Kumar, S. Haque, K. Ayasolla, S. Saha, X. Lan, A. Malhotra, M. A. Saleem, K. Skorecki, P. C. Singhal

Journal Articles

© 2019 Federation of European Biochemical Societies We evaluated alterations in the structural configurations of channels and activation of nucleotide-binding domain, leucine-rich-containing family, pyrin domain-containing-3 (NLRP3) inflammasome formation in apolipoprotein L1 (APOL1) risk and nonrisk milieus. APOL1G1- and APOL1G2-expressing podocytes (PD) displayed enhanced K+ efflux, induction of pyroptosis, and escalated transcription of interleukin (IL)-1β and IL-18. APOL1G1- and APOL1G2-expressing PD promoted the transcription as well as translation of proteins involved in the formation of inflammasomes. Since glyburide (a specific inhibitor of K+ efflux channels) inhibited the transcription of NLRP3, IL-1β, and IL-18, the role of K+ efflux in the activation …

Morphea (Localized Scleroderma) Presenting With Recurrent Skin And Soft Tissue Infections: A Diagnostic Dilemma., A. M. Khatri, M. Mclemore, P. Malhotra

Journal Articles

Morphea or localized scleroderma is reported to be triggered through diverse stimuli. We present a case of morphea that presented as a non-healing wound with superimposed methicillin-sensitive Staphylococcus aureus (MSSA) infection. In our case, morphea was thought to have been potentially triggered by a post-surgical infection. We discuss the potential infectious triggers and common infections that may confound the diagnosis.
