Abstract: One of the basic principles in immunology is the capacity to distinguish self from non-self (foreign). Immunological response occurs for foreign macromolecules (antigens). If transplantation of a tissue/organ is done within the same individual, there is no rejection. At the same time if it is done within the same species or from one species to another, rejection occurs. Certain sites in our body are able to tolerate the introduction of antigens without eliciting an immune response. This tolerance is what is known as immune privilege. There are well known privileged sites in the human body like cornea of the eye, the uterus, the testis and the brain.
