Clinical intestinal transplantation: New perspectives and immunologic considerations [PDF]

open access: yes, 1998
Background: Although tacrolimus-based immunosuppression has made intestinal transplantation feasible, the risk of the requisite chronic high- dose treatment has inhibited the widespread use of these procedures.

Transgenic expression of the Ly49A natural killer cell receptor confers class I major histocompatibility complex (MHC)-specific inhibition and prevents bone marrow allograft rejection. [PDF]

open access: yes, 1996
Natural killer (NK) cells and some T cells are endowed with receptors specific for class I major histocompatibility complex (MHC) molecules that can inhibit cellular effector functions.

Bone Grafting and Bone Graft Substitutes [PDF]

open access: yesJournal of Animal and Veterinary Advances, 2010
Restoring skeletal integrity and bone tissue regeneration is still a significant challenging issue. In this regard, bone grafting have been used to augment orthopedic repairs in human and veterinary surgery for several decades and still being under many investigation to hunt for new approaches to improve bone healing following incidences of bone ...
