During infections, the immune system needs to distinguish foreign antigens that are expressed by invading bacteria and viruses from self-antigens that are expressed by cells of the body. If not, the ...

Studying mice, researchers have discovered that roseolovirus can trigger autoimmunity in a previously unknown way: by disrupting the process by which immune cells learn to avoid targeting their own ...

A study provides evidence that the prevalence of autoimmunity -- when the immune system goes awry and attacks the body itself -- has increased in the United States in recent years. A study published ...

A single signaling pathway controls whether immune cells attack or befriend cells they encounter while patrolling our bodies, researchers at Stanford Medicine have found. Manipulating this pathway ...

Autoimmunity When our bodies are exposed to a virus — or any infection — it recognizes proteins and other molecules on the invading virus as “not us.” Scientists refer to this as an antigen. We then ...

Summary of the research: This study revealed that T cells can discriminate between self- and neoself- antigens, and that neoself-reactive T cells are involved in causing autoimmune diseases. Osaka, ...
