Researchers identify proteins that contribute to the pathogenicity of COVID-19 virus
Researchers at Texas Biomedical Research Institute (Texas Biomed) have narrowed down the proteins enabling SARS-CoV-2 to cause disease. Using advanced genetic engineering techniques developed at Texas Biomed, they systematically deleted the genetic code for five of the virus s accessory proteins, one at a time, to see how each one affected the virus s ability to spread and cause illness. The research was published online this month in the
Journal of Virology.
They found two proteins that seem to contribute most to the virus s pathogenicity, or ability to cause COVID-19 disease. When individually lacking those proteins, the virus did not replicate as much as the natural virus in cells, suggesting they play a critical role in its spread. In contrast, spread was not significantly reduced when the other proteins were deleted.
Memory biomarkers confirm aerobic exercise helps cognitive function in older adults ANI | Updated: Jun 14, 2021 09:31 IST
Washington [US], June 14 (ANI): Until now, systemic biomarkers to measure exercise effects on brain function and that link to relevant metabolic responses were lacking. A recent study shows a memory biomarker, myokine Cathepsin B (CTSB), increased in older adults following a 26-week structured aerobic exercise training.
The positive association between CTSB and cognition, and the substantial modulation of lipid metabolites implicated in dementia, support the beneficial effects of exercise training on brain function and brain health in asymptomatic individuals at risk for Alzheimer s.
Increasing evidence shows that physical activity and exercise training may delay or prevent the onset of Alzheimer s disease (AD). In ageing humans, aerobic exercise training increases grey and white matter volume enhances blood flow and impr
