BACKGROUND Antithrombin III (AT-III) is an antithrombotic agent with known anti-inflammatory properties that is also known to attenuate acute inflammation, prevent ischemia-reperfusion injury, and disseminated intravascular coagulation (DIC) associated with sepsis and endotoxemia. Here, we examined the ability of AT-III to modify parameters of acute(More)
Cytokines appear to play a major role in acute transplant rejection (AR); however, the specific cytokines initiating AR are not known. To investigate gamma-interferon messenger RNA (mRNA) as a key factor in AR induction, we performed reverse transcription-polymerase chain reaction (RT-PCR) on renal allograft fine-needle aspirates (FNA). Fifteen FNA from 15(More)
BACKGROUND Platelets are known to play an important role in the pathogenesis of adult respiratory distress syndrome as well as preservation-reperfusion injury of liver allografts. However, the role of platelets in pulmonary preservation-reperfusion injury is unknown. In this study, we examined whether the extent of platelet accumulation in the preserved and(More)
UNLABELLED Cytokine gene expression is a critical component of the lung allograft rejection (AR) response and tolerance development in rat models. In order to determine the specificity of cytokine gene expression for AR and tolerance, we examined cytokine (interleukin-2) (IL-2), (gamma-interferon) (gamma-IFN), IL-4, IL-10 and tumor necrosis factor-alpha(More)
Chronic rejection is a major cause of graft failure in solid organ transplants after the first year. A characteristic lesion in a variety of chronically rejecting organs is a fibrointimal proliferative arteriosclerosis. It has been speculated that approaches to tolerance induction may be effective in obviating not only acute, but also chronic, rejection. A(More)
Lung transplantation is now routinely performed for a wide range of end-stage cardiopulmonary disorders. Despite overcoming the problems associated with early acute rejection, chronic rejection (CR) in the form of obliterative bronchiolitis has emerged as the primary cause of late graft loss. The mechanisms involved in the development of CR of lung(More)
BACKGROUND Microemulsion cyclosporine, mycophenolate mofetil, and prednisone have become a common immunosuppressive protocol in renal transplantation. We identified lymphocytic infiltrates in transplant fine-needle aspirates and core biopsies from patients on this regimen without acute rejection clinically or by standardized morphological criteria and(More)
