Reduction of Graft-versus-Host-Disease in NOD.Cg-Prkdc Il2rg/SzJ (NSG) mice by co-transplantation of syngeneic human umbilical cord-derived mesenchymal stromal cells (UC-MSCs).

Transplant Cell Ther 2021 May 5. Epub 2021 May 5.

Fraunhofer Institute for Cell Therapy and Immunology, Leipzig, Germany.

Background: Graft-versus-Host Disease (GvHD) is one of the major complications following hematopoietic stem cell transplantation (HSCT), which remains the only curative therapy for many malignant diseases of the hematopoietic system. The immunomodulatory potential of mesenchymal stromal cells (MSCs) to treat GvHD is currently being tested in various preclinical and clinical trials.

Objectives: As the results of the preclinical and clinical trials on the use of MSCs to treat GvHD have not been consistent, we analyzed the potential beneficial effects of syngeneic versus allogenic treatment setting, culture expansion of the MSC and various MSC cell doses and time points of MSC transplantation in a murine GvHD model.

Interdependencies between Toll-Like Receptors in Leishmania infection.

Immunology 2021 May 8. Epub 2021 May 8.

Tripura University, Agartala, Tripura, India.

Multiple pathogen-associated molecular patterns (PAMPs) on a pathogen's surface imply their simultaneous recognition by the host cell membrane-located multiple PAMP-specific Toll-Like Receptors (TLRs). The TLRs on endosomes recognize internalized pathogen-derived nucleic acids and trigger anti-pathogen immune responses aimed at eliminating the intracellular pathogen. Whether the TLRs influence each others expression and effector responses- termed TLRs inter-dependency- remains unknown. Read More

Cancer Rep (Hoboken) 2021 May 8:e1410. Epub 2021 May 8.

University of Sydney, Camperdown, New South Wales, Australia.

Background: Management of the node-negative neck in oral maxillary squamous cell carcinoma (SCC), encompassing the hard palate and upper alveolar subsites of the oral cavity, is controversial, with no clear international consensus or recommendation regarding elective neck dissection in the absence of cervical metastases.

ADIPOR1 deficiency-induced suppression of retinal ELOVL2 and docosahexaenoic acid levels during photoreceptor degeneration and visual loss.

Cell Death Dis 2021 May 7;12(5):458. Epub 2021 May 7.

Laboratory of Retinal Cell Biology, Tokyo, Japan.

Lipid metabolism-related gene mutations can cause retinitis pigmentosa, a currently untreatable blinding disease resulting from progressive neurodegeneration of the retina. Here, we demonstrated the influence of adiponectin receptor 1 (ADIPOR1) deficiency in retinal neurodegeneration using Adipor1 knockout (KO) mice. Adipor1 mRNA was observed to be expressed in photoreceptors, predominately within the photoreceptor inner segment (PIS), and increased after birth during the development of the photoreceptor outer segments (POSs) where photons are received by the visual pigment, rhodopsin.

Social Media Use in COPD Patients in Germany and Switzerland.

Pneumologie 2021 May 7. Epub 2021 May 7.

Pforzheim University, School of Engineering, Pforzheim, Germany.

Use of social media and the Internet has changed the information-seeking behaviour and exchange of experience and information by patients. Passive observation of such online interaction between patients (social media listening) is conducted in order to understand the burden of the disease, symptom perception, and expectations from a patient perspective. For most conditions, it remains to be established how representative the social media user community is for the overall patient population. Read More

Tissue-Based SARS-Cov-2 Detection in Fatal COVID-19 Infections: Sustained Direct Viral-Induced Damage is Not Necessary to Drive Disease Progression.

Hum Pathol 2021 May 4. Epub 2021 May 4.

Departments of Pathology, Molecular and Cell-Based Medicine, The Icahn School of Medicine at Mount Sinai Hospital, New York, NY. Electronic address:

Background: Coronavirus disease 2019 (COVID-19) is an ongoing pandemic caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Although viral infection is known to trigger inflammatory processes contributing to tissue injury and organ failure, it is unclear whether direct viral damage is needed to sustain cellular injury. An understanding of pathogenic mechanisms has been handicapped by the absence of optimized methods to visualize the presence and distribution of SARS-CoV-2 in damaged tissues. Read More

Current management of melanoma patients with nodal metastases.

Clin Exp Metastasis 2021 May 7. Epub 2021 May 7.

Department of Surgery, Morsani School of Medicine, University of South Florida, Tampa, FL, USA.

The management of melanoma patients with nodal metastases has undergone dramatic changes over the last decade. In the past, the standard of care for patients with a positive sentinel lymph node biopsy (SLNB) was a completion lymph node dissection (CLND), while patients with palpable macroscopic nodal disease underwent a therapeutic lymphadenectomy in cases with no evidence of systemic spread. However, studies have shown that SLN metastases present as a spectrum of disease, with certain SLN-based factors being prognostic of and correlated with outcomes. Read More

Implications of extreme serum neurofilament light chain levels for the management of patients with relapsing multiple sclerosis.

Ther Adv Neurol Disord 2021 20;14:17562864211001977. Epub 2021 Apr 20.

Department of Neurology, Focus Program Translational Neuroscience (FTN), Rhine Main Neuroscience Network (rmn²), University Medical Center of the Johannes Gutenberg University Mainz, Langenbeckstrasse 1, Mainz 55131, Germany.

Background: Serum neurofilament light chain (sNfL) is a promising biomarker to complement the decision-making process in multiple sclerosis (MS) patients. However, although sNfL levels are able to detect disease activity and to predict future disability, the growing evidence has not yet been translated into practicable recommendations for an implementation into clinical routine.

Methods: The observation of a patient with extensive inflammatory activity in magnetic resonance imaging (MRI) along with an extremely high sNfL level in the absence of any clinical symptoms prompted us to investigate common characteristics of our MS patients with the highest sNfL levels in a retrospective cohort study.
