Biologically active polysaccharides from red algae known as carrageenan appear to suppress the activity of peritoneal phagocytes in mice, generating an immunosuppressant effect.
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.
People who take immunosuppressant medications are less likely to develop Parkinson's disease, a new study reveals.
