About one-third of these patients develop antibodies against foreign proteins in the donated blood, which makes it very difficult to find compatible blood for subsequent treatment.

Myasthenia gravis is an autoimmune channelopathy: it features antibodies directed against proteins that are naturally present in the body.

For instance, the duplicated version of the protein should still be functional, since otherwise evolution would quickly select against such proteins.

The technique's most important implication is that it holds the promise of making antibodies against deadly human proteins.

They determined that one type of T-cell receptor predominated in the rally against proteins on the surface of myelin tissue.

Monoclonal antibodies against pre-S proteins have recently become available for tissue staining.

The antibodies appear to reflect an immune system attack against proteins that help protect nerve tissue.

The evidence accumulated to date clearly points towards an autoimmune Th1 disease directed against proteins associated with choroidal melanin.

Antibodies are usually raised against foreign proteins, such as those made by a replicating virus or invading bacterium.

Patients with rheumatoid arthritis often have detectable antibodies against proteins containing citrulline.
