New research has revealed that red blood cells function as critical immune sensors by binding cell-free DNA, called nucleic acid, present in the body’s circulation during sepsis and COVID-19, and that this DNA-binding capability triggers their removal from circulation, driving inflammation and anemia during severe illness and playing a muchContinuar Leyendo
The ability to edit the genome by altering the DNA sequence inside a living cell is powerful for research and holds enormous promise for the treatment of diseases. However, existing genome editing technologies frequently result in unwanted mutations or can fail to introduce any changes at all. These problems haveContinuar Leyendo
Some viral diseases could possibly contribute to neurodegeneration. DZNE researchers report this in the scientific journal Nature Communications. Their assessment is based on laboratory experiments in which they were able to show that certain viral molecules facilitate intercellular spreading of protein aggregates that are hallmarks of brain diseases like Alzheimer’s. TheseContinuar Leyendo
