Infants born to COVID-infected mothers found to have triple the risk of developing respiratory distressNew UCLA-led research finds that infants born full term to mothers who were infected with COVID-19 during pregnancy had three times the risk of having respiratory distress compared with unexposed infants, even though they themselves were not infected with the virus. The risk was significantly lower when the mothers infected during pregnancy were previously vaccinated. | |

Researchers uncover new signaling pathway in the development of atherosclerosisAtherosclerosis, a chronic inflammatory disease of the inner walls of blood vessels, is responsible for many cardiovascular conditions. Dendritic cells, which act to recognize foreign substances in the body and mount an immune response, play an important role in the disease. They produce the signaling protein CCL17, a chemokine, which influences the activity and mobility of T cells, which track down infected cells in the body and attack the pathogens. However, CCL17 can also promote cardiovascular pathologies. | |
How a timekeeping gene affects tumor growth depends entirely on contextA new study has found that the circadian clock—which synchronizes physiological and cellular activities with the day-night cycle and is generally thought to be tumor suppressive—in fact has a contextually variable role in cancer. | |
Research team identifies 'protective switches' in SARS-CoV-2 protein that defend against immune systemOver 700 million people were infected and almost seven million died, making SARS-CoV-2 the most devastating pandemic of the 21st century. Vaccines and medication against COVID-19 have been able to mitigate the course of the disease in many people and contain the pandemic. However, the danger of further outbreaks has not been averted. The virus is constantly mutating, which enables it to infect human cells and multiply more and more effectively. In addition, it is developing a variety of strategies against the human immune system in a "molecular arms race." | |

New methodological approach allows more precise summary of study resultsBefore new drugs are launched on the market they are tested in clinical studies in which one group of study participants often receives the new treatment and another group receives the current standard treatment. The results of these studies are needed for regulatory approval and later for so-called benefit assessments, which compare the advantages and disadvantages of the new and previous treatment: Is the new treatment more effective, does it have milder or more severe side effects, how do patients do afterwards, and so on. If the new treatment is better overall, it has an "added benefit." | |
