How COVID Changed Science

How COVID Changed Science
What is unprecedented is not just the speed and focus with which the community responded to the pandemic but also the singular willingness of scientists all over the world to share new ideas and data immediately and transparently

Rarely in recent memory has the world faced such an immediate and widespread global threat as complex as COVID-19. In its face, a select few have risen to the occasion, none more cherished and admired perhaps than the health care workers staffing the front lines. But standing close behind them in the trenches are the scientists and researchers who are among the very few who truly understand the scope of our evolutionary battle with the virus. Since the start of the pandemic, our scientists have acted with unprecedented speed and coordinated action to deliver us an armamentarium of medical weaponry to confront this global threat. ....

Does Obesity Affect Immunity?


Jan 27 2021 Read 23357 Times
New research from Harvard Medical School warns obesity could impair the function of immune cells and potentially accelerate tumour growth. Citing competition for fuel as a key driver, scientists warn a high-fat diet could allow cancer cells to outperform immune cells and spread within the body. The study builds on existing research suggesting links between obesity and more than a dozen different types of cancer, with scientists previously exploring drivers such as chronic inflammation and metabolic changes.
Working from Harvard Medical School, the team conducted studies on mice to uncover new insight into the relationship between obesity and cancer. The results could spark exciting change for cancer immunotherapy, with the team noting obesity allows malignant cells to outperform a critical type of tumour-killing immune cell known as CD8+ T. Used in many different types of immunotherapies, CD8+ T kickstart the immune system and play a critical ....

Obesity and tumours
Obesity is one of the major cancer risk factors. But how are they related? A new study has noted that a diet containing high fat impels the immune system’s T-cells which accelerates tumour growth. “We now know there is a metabolic tug-of-war between T-cells and tumor cells that changes with obesity,” says co-senior author Arlene Sharpe from Blavatnik Institute. So there is a high chance that a person with a ....
