They are protected by other means like immunologic tolerance and immunomodulation.

Chimeras typically have immunologic tolerance to both cell lines.

One of the primary functions of the thymus is to prevent autoimmunity through the process of central tolerance, immunologic tolerance to self antigens.

Our inability to show an increase in X-chromosome skewing in females with autoimmunity does not eliminate this as an etiologic contributor to loss of immunologic tolerance.

Field's research focuses on mechanisms of acquired immunologic tolerance by studying mouse models of neonatal tolerance and acquired tolerance in the adult.

Renal transplantation replaces kidney function by inserting into the body a healthier kidney from an organ donor and inducing immunologic tolerance of that organ with immunosuppression.

A unifying feature of autoimmune disorders appears to be the loss of immunologic tolerance to self-antigens, and in many of these diseases there is evidence that T-cell tolerance has been broken.

Field has conducted research [2] in transplantation immunology, immunologic tolerance and CD4+CD25+ regulatory cells and has a patent pending for: CD4+CD25+ Inhibitory Hybridoma Clones.

Dr. Weiner, for his part, writes that he is planning to test new combination therapies, oral agents, drugs that affect degeneration and drugs to induce immunologic tolerance that do not have the potentially toxic side effects of chemotherapy.
