The presented allo-HLApep can be recognized by the T cell receptors (TCR) of the recipient's allo-HLA-specific follicular helper CD4+ T cells (allo-[T.sub.FH]); these cells have undergone thymic selection, which creates a pool of allo-[T.sub.FH] that expresses TCR with a low affinity for "self' peptides/HLA class II complex and a high affinity for "nonself" ones [12,13].
It has been reported that several temperate echinoderm species are capable of differentiating self from nonself tissues through allograft rejection studies (Smith & Davidson 1992, Smith et al.

Biomarkers that assess lymphocyte response to nonself antigens would be useful, the caveat being that today's immunosuppressants are not specific to alloantigens.

This cluster of 128 genes and surrounding genetic material plays an important role in the immune system, The genes encode molecules on the cell surface that recognize self from nonself and detect pathogens and parasites.
These life-history attributes, in turn, promote tissue contacts between isogeneic (self) and allogeneic (nonself) conspecifics (Grosberg 1988) and often lead to intense intraspecific competition for space (Buss 1990).
One can assume that, to reduce the loss of resources and energy, the surface interactions with the environment and nonself would be energy sparing and simple--preferably nonspecific, passive, and neutralizing (such as protective secretion of mucins, secretory IgA-mediated antigen exclusion, lactoferrin, etc.).
