“The study investigators injected pregnant normal mice and mice that lacked IL-15 with polyinosinic:polycytidylic (poly I:C), a chemical used in the laboratory setting to simulate a viral infection. Poly I:C interacts with toll-like receptors to elicit an immune response.”

“Levels of neurofilament light chain were higher among the military personnel who had experienced Epstein-Barr infection. These findings suggest that Epstein-Barr virus is the causal factor in the development of multiple sclerosis and underscore the need for developing vaccines against the virus.”

“When the infection has resolved, B cells called long-lived bone marrow plasma cells return to the bone marrow where they lie dormant until exposure to the same pathogen reoccurs, providing long-lasting immunity.”

“However, it may also complicate COVID-19 vaccine trials if some subjects have pre-existing immunity. These findings suggest that prior exposure to a related coronavirus stimulates the production of SARS-CoV-2 reactive T cells that persist in the body.”

“As the global COVID-19 pandemic continues, new ways of battling SARS-CoV-2, the virus that causes the disease, are needed, especially in areas where vaccine distribution is low. Sunlight is an inexpensive and widely-available tool for disinfection, but may require too much time to be effective.”

“Insufficient production of either the alpha or beta proteins due to genetic defect impairs oxygen transport via the red blood cells, inducing anemia and often necessitating blood transfusions. The study involved 22 people (ages 4 to 34 years) with transfusion-dependent beta-thalassemia.”

“In the past, humans' primary exposure to blue light was from the sun, but in modern times, electronic devices – TVs, computer screens, and cell phones – expose us to increasing amounts of blue light, often during times of the day or night that are out of sync with our bodies' natural rhythms.”

“Because people with obesity experience increased baseline inflammaging, they may be at greater risk of developing long-term autoimmune complications for COVID-19; however, no published studies have yet addressed this concern.”

“They used a machine learning model to compute the expected death rates among the patients based on characteristics such as the patients' age, sex, median vitamin D levels, and whether they had diabetes. The timeframe for the data collection preceded the advent of vaccines against COVID-19.”

“The investigators gave one group of mice an injection of casein with adjuvants, which are compounds added to vaccines to increase the body's antibody response. To compare casein to other milk proteins, they also immunized one group of mice with alpha-lactalbumin and another with beta-lactoglobulin, both whey proteins, for a total of three mouse groups.”
