In the so-called indirect pathway of allorecognition, recipient T lymphocytes recognize antigens of the graft donor after they are presented by the recipient’s own antigen-presenting cells. [humpath.com]

The physiological function of the MHC molecules is to present antigenic peptides to T cells, since the T lymphocytes only recognize antigen when presented in a complex with an MHC molecule. [emedicine.medscape.com]

CONCLUSIONS: Prednisolone remains the treatment of choice for management and treatment of graft rejection; however, since the introduction of difluprednate, its use has declined slightly since the introduction of difluprednate. [ncbi.nlm.nih.gov]
