Two studies reveal the role bile acids play in immunity and inflammation.
Depression during pregnancy can directly influence the development of the immune system in children. Children whose mothers reported symptoms of prenatal depression had lower levels of immunoglobulin A in their guts. Lower immunity placed babies at risk of respiratory and gastrointestinal infections, as well as allergies and asthma. Additionally, children may face an increased risk of depression, obesity, and autoimmune diseases as they age.
Intermittent social distancing may have to be employed to reduce the burden on the health care system as a result of COVID-19. If COVID-19 is a seasonal ailment, like the flu, a new model shows physical distancing occurring between 25 and 75% of the time would help build up herd immunity and prevent health system overload.
Historical data from Flu Watch about other coronaviruses reveals they appear to have a seasonal pattern, with peaks occurring during winter. Only small amounts of other coronavirus infections were transmitted during the summer. The findings support the hypothesis that COVID-19 may have lower levels of transmission during the summer, but this may reverse during the winter months if there is still a large, susceptible population.
Study reveals the body's immune system can recognize SARS-CoV-2, the virus that causes COVID-19, in many ways. The findings should help dispel fears the virus may elude ongoing efforts to create a successful vaccine.
Researchers report a cleaner living environment may not detrimentally impact a child's developing immune system, as current theories suggest.
Researchers identified differences in isoforms that control Treg cells and how that affects the body's immune system response.
