Members of the cytokine receptor family are composed of several noncovalently linked chains with sequence and structure homologies in their ex-tracellular domain. Receptor subfamily members share at least one component: thus the receptors for inter-leukin (IL) 2 and ILl5 have common ~ and 3" chains, while those for IL2, 4, 7, and 9 have a common 3' chain.(More)
In the 30 years since the rabbit antithymocyte globulin (rATG) Thymoglobulin(®) was first licensed, its use in solid organ transplantation and hematology has expanded progressively. Although the evidence base is incomplete, specific roles for rATG in organ transplant recipients using contemporary dosing strategies are now relatively well-identified. The(More)
BACKGROUND Extended soft tissue defects of the face are difficult to reconstruct, and autologous tissue transfers usually lead to poor cosmetic and functional outcomes. We judged that composite tissue transplantation could be valuable in facial reconstructive surgery. METHODS We transplanted the central and lower face of a brain-dead woman onto a woman(More)
Organ transplantation is widely acknowledged as the best option for end stage failure of vital organs. Long-term graft survival is however limited by graft rejection, a destructive process resulting from the response of recipient's immune system against donor-specific alloantigens. Prevention of rejection currently relies exclusively on immunosuppressive(More)
During chronic inflammation, immune effectors progressively organize themselves into a functional tertiary lymphoid tissue (TLT) within the targeted organ. TLT has been observed in a wide range of chronic inflammatory conditions but its pathophysiological significance remains unknown. We used the rat aortic interposition model in which a TLT has been(More)
Nocardiosis is a rare opportunistic infection caused by Nocardia spp., an aerobic actinomycete, that mainly affects patients with cell-mediated immunity defects, such as transplant recipients. Despite recent progress regarding Nocardia identification and changes in taxonomic assignment, many challenges remain for the diagnosis or management of nocardiosis.(More)
OBJECTIVES To assess the long term outcomes of transplantation using expanded criteria donors (ECD; donors aged ≥ 60 years or aged 50-59 years with vascular comorbidities) and assess the main determinants of its prognosis. DESIGN Prospective, population based cohort study. SETTING Four French referral centres. PARTICIPANTS Consecutive patients who(More)
BACKGROUND The use of the immunosuppressant sirolimus in kidney transplantation has been made problematic by the frequent occurrence of various side effects, including paradoxical inflammatory manifestations, the pathophysiology of which has remained elusive. METHODS 30 kidney transplant recipients that required a switch from calcineurin inhibitor to(More)
PURPOSE Hand allograft has recently emerged as a therapeutic option for upper limb amputees. Functional neuroimaging studies have progressively revealed sensorimotor cortices plasticity following both amputation and transplantation. The purpose of our study was to assess and characterize the functional recovery of the visuo-motor control of prehension in(More)
After the first year post transplantation, prognostic mortality scores in kidney transplant recipients can be useful for personalizing medical management. We developed a new prognostic score based on 5 parameters and computable at 1-year post transplantation. The outcome was the time between the first anniversary of the transplantation and the patient's(More)
