Recovered coronavirus patients show a wide range of immune responses following the infection, with about half from a current study showing sustained antibodies two weeks later. Results indicate which parts of the virus are most effective at triggering the immune responses.
A new mathematical model examined the immune response in patients with coronavirus. The findings suggest adaptive immune response may kick in before target immune cells are depleted, slowing the infection. The interaction of the innate and adaptive immune response may explain why some with coronavirus experience a second wave infection, appearing to get better before the symptoms return and get worse. Other studies have shown those who received immunosuppressants at the start of infection had a better clinical outcome than those who did not.
Immune cells in the meninges come from bone marrow in the skull and migrate to the brain through special channels without passing through the blood. These immune cells help to guard the brain and spinal cord against inflammation and infection.
Researchers have discovered a possible trigger for autoimmune diseases such as lupus, Crohn's disease and MS. Findings may explain how women are more susceptible to autoimmune disorders than men.
