Protective T cells remain 20 months after COVID
by University of Gothenburg Th1 cells remain active against SARS-CoV-2 for at least 20 months after infection. Credit: Proceedings of the National Academy of Sciences (2022). DOI: 10.1073/pnas.2203659119 Patients infected with SARS-CoV-2 develop protective immune responses, mediated by virus-specific T cells and antibodies, shortly after the infection. There is concern, however, that immunity does not persist over...

Heated tobacco products, or HTPs, are often confused with e-cigarettes, which heat liquid that can...
Early Alzheimer’s detection up to 17 years in advance
by Ruhr-Universitaet-Bochum Receiver-operating curve (ROC) analyses to determine the discriminative power of all biomarkers to distinguish between patients with Alzheimer’s disease (AD) and controls within 17 years. Simoa biomarkers are log-transformed values. Participants with missing apolipoprotein E (APOE) status have been excluded (n = 12). (A) ROC analyses revealed an area under the curve (AUC) for AD...

Study suggests SARS-CoV-2 virus enters the brain by using cells in the nose to make nanotube tunnels
by Bob Yirka, Medical Xpress SARS-CoV-2 can reach SH-SY5Y neuronal cells from Vero E6 permissive cells. Infected Vero E6 cells (donor cells) were cocultured with SH-SY5Y neuronal cells previously stably transfected with a vector that expresses mCherry (acceptor cells). Coculture was fixed at 24 and 48 hours. (A to G) Confocal micrographs showing 48 hours...
