Circulating miR-155 may predict chances of survival in hospitalized COVID-19 patients
Circulating miR-155 may predict chances of survival in hospitalized COVID-19 patients
Scientists from Israel have recently estimated the levels of circulating microRNAs (miRNAs) in hospitalized coronavirus disease 2019 (COVID-19) patients with the aim of identifying prognostic biomarkers for disease severity. They have identified miR-155, an important regulatory molecule in the immune system, as a potential biomarker to predict COVID-19 severity and mortality. // 22.2.2022

A single-cell atlas reveals shared and distinct immune responses and metabolism during SARS-CoV-2 and HIV-1 infections
SARS-CoV-2 and HIV-1 are RNA viruses that have killed millions of people worldwide. Understanding the similarities and differences between these two infections is critical for understanding disease progression and for developing effective vaccines and therapies, particularly for 38 million HIV-1+ individuals who are vulnerable to SARS-CoV-2 co-infection. // 11.1.2022

Autoantibodies linked to autoimmune diseases associate with COVID-19 outcomes
The SARS-CoV-2 infection is associated with increased levels of autoantibodies targeting immunological proteins such as cytokines and chemokines. Reports further indicate that COVID-19 patients may develop a wide spectrum of autoimmune diseases due to reasons not fully understood. // 18.2.2022

Brain cortical changes are related to inflammatory biomarkers in hospitalized SARS-CoV-2 patients with neurological symptoms
Brain cortical changes are related to inflammatory biomarkers in hospitalized SARS-CoV-2 patients with neurological symptoms
Increasing evidence shows that the brain is a target of SARS-CoV-2. However, the consequences of the virus on the cortical regions of hospitalized patients are currently unknown. The purpose of this study was to assess brain cortical gray matter volume (GMV), thickness (Th), and surface area (SA) characteristics in SARS-CoV-2 hospitalized patients with a wide range of neurological symptoms and their association with clinical indicators of inflammatory processes. // 15.2.2022
