NMD inhibition by 5-azacytidine augments presentation of immunogenic frameshift-derived neoepitopes.

iScience 2021 Apr 1;24(4):102389. Epub 2021 Apr 1.

Molecular Medicine Partnership Unit (MMPU), Heidelberg University, 69120 Heidelberg, Germany.

Frameshifted protein sequences elicit tumor-specific T cell-mediated immune responses in microsatellite-unstable (MSI) cancers if presented by HLA class I molecules. However, their expression and presentation are limited by nonsense-mediated RNA decay (NMD). We employed an unbiased immunopeptidomics workflow to analyze MSI HCT-116 cells and identified >10,000 HLA class I-presented peptides including five frameshift-derived InDel neoepitopes. Read More

DNGR-1 limits Flt3L-mediated antitumor immunity by restraining tumor-infiltrating type I conventional dendritic cells.

J Immunother Cancer 2021 May;9(5)

Centro Nacional de Investigaciones Cardiovasculares Carlos III (CNIC), Madrid, Spain

Background: Conventional type 1 dendritic cells (cDC1s) are central to antitumor immunity and their presence in the tumor microenvironment associates with improved outcomes in patients with cancer. DNGR-1 (CLEC9A) is a dead cell-sensing receptor highly restricted to cDC1s. DNGR-1 has been involved in both cross-presentation of dead cell-associated antigens and processes of disease tolerance, but its role in antitumor immunity has not been clarified yet. Read More

Evolution of Disparities in Prostate Cancer Treatment: Is This a New Normal?

Am Soc Clin Oncol Educ Book 2021 Mar;41:1-12

Winship Cancer Institute, Emory University, Atlanta, GA.

Despite notable screening, diagnostic, and therapeutic advances, disparities in prostate cancer incidence and outcomes remain prevalent. Although commonly discussed in the context of men of African descent, disparities also exist based on socioeconomic level, education level, and geographic location. The factors in these disparities span systemic access issues affecting availability of care, provider awareness, and personal patient views and mistrust. Read More

Recent developments in the diagnosis and treatment of extrapulmonary non-tuberculous mycobacterial diseases.

Int J Tuberc Lung Dis 2021 May;25(5):340-349

Department of Clinical Research, ICMR, NIRT, Chennai, India.

Diseases due to pathogenic mycobacteria cause significant health and economic impact on humans worldwide. Although mycobacterial diseases primarily affect the lungs, the involvement of extrapulmonary organs has also gained ground, particularly among individuals with co-existing medical conditions. Besides complex organisms, non-tuberculous mycobacteria (NTM) are also known to cause pulmonary and extrapulmonary diseases. Read More

High resolution structural and functional MRI of the hippocampus in young adults with Down syndrome.

Brain Commun 2021 19;3(2):fcab088. Epub 2021 Apr 19.

Department of Pediatrics, Case Western Reserve University, Cleveland, OH 44106, USA.

Down syndrome is the phenotypic consequence of trisomy 21, with clinical presentation including both neurodevelopmental and neurodegenerative components. Although the intellectual disability typically displayed by individuals with Down syndrome is generally global, it also involves disproportionate deficits in hippocampally-mediated cognitive processes. Hippocampal dysfunction may also relate to Alzheimer's disease-type pathology, which can appear in as early as the first decade of life and becomes universal by age 40. Read More

Clinical and Intestinal Histopathological Findings in SARS-CoV-2/COVID-19 Patients with Hematochezia.

Case Rep Gastroenterol 2021 Jan-Apr;15(1):408-417. Epub 2021 Mar 22.

Department of Pathology, NYU Langone Health, New York, New York, USA.

Gastrointestinal (GI) symptoms of SARS-CoV-2/COVID-19 in the form of anorexia, nausea, vomiting, abdominal pain and diarrhea are usually preceded by respiratory manifestations and are associated with a poor prognosis. Hematochezia is an uncommon clinical presentation of COVID-19, and we hypothesize that older patients with significant comorbidities (obesity and cardiovascular) and prolonged hospitalization are susceptible to ischemic injury to the bowel. We reviewed the clinical course, key laboratory data including acute-phase reactants, and drug/medication history in 2 elderly male patients admitted for COVID-19 respiratory failure. Read More

Combined Liposuction and Physiologic Treatment Achieves Durable Limb Volume Normalization in Class II-III Lymphedema: A Treatment Algorithm to Optimize Outcomes.

Ann Plast Surg 2021 May;86(5S Suppl 3):S384-S389

From the Division of Plastic and Reconstructive Surgery, Stanford University, Palo Alto, CA.

Introduction: Outcomes of surgical lymphedema treatment are currently suboptimal. Physiologic procedures including lymphovenous anastomosis (LVA) and vascularized lymph node transfer (VLNT) reestablish lymphatic flow but cannot correct fibroadipose deposition, whereas liposuction alone cannot prevent disease progression. We propose a treatment algorithm combining liposuction with LVA or VLNT that can achieve normal limb volumes and prevent disease progression in stage II-III lymphedema. Read More

The DnaK/DnaJ Chaperone System Enables RNA Polymerase-DksA Complex Formation in Salmonella Experiencing Oxidative Stress.

mBio 2021 May 11;12(3). Epub 2021 May 11.

University of Colorado School of Medicine, Department of Immunology & Microbiology, Aurora, Colorado, USA

Our previous biochemical approaches showed that the oxidoreductase activity of the DnaJ protein facilitates the interaction of oxidized DksA with RNA polymerase. Investigations herein demonstrate that under biologically relevant conditions the DnaJ- and DksA-codependent activation of the stringent response in undergoing oxidative stress involves the DnaK chaperone. Oxidation of DksA cysteine residues stimulates redox-based and holdase interactions with zinc-binding and C-terminal domains of DnaJ. Read More
