Abstract:
Since the earliest days of transplantation, immunobiologists have sought means to prevent recognition and rejection of foreign tissue. The goal of these strategies is the retention of recipient immune function while selectively avoiding graft injury. Although considerable theoretical and technical problems remain, an analogous problem and solution already exists in nature. Here, we discuss the mechanisms by which organisms preclude or control autotoxicity, and for each, consider the corollaries between prevention of autotoxicity and graft rejection. Further study of these controls, including structural and conditional tolerance and accommodation, will offer insight into new therapies for allo- and xenotransplantation.

Avoidance Learning and Learned Helplessness
Avoidance learning occurs when an organism learns that a specific behavior can prevent an unpleasant outcome. For example, a student who receives a bad grade may start studying harder to avoid future poor grades. This behavior persists even when the negative outcome is no longer present. Avoidance learning is powerful because it maintains behavior in the absence of the...
