Acute rejection is a category of rejection that occurs on the timescale of weeks to months, with most episodes occurring within the first 3 months to 1 year after transplantation. [ 6 ] [ 8 ] Unlike hyperacute rejection, acute rejection is thought to arise from two distinct immunological mechanisms as lymphocytes , a subset of white blood cells ...
Lung transplantation is the therapeutic measure of last resort for patients with end-stage lung disease who have exhausted all other available treatments without improvement. A variety of conditions may make such surgery necessary. As of 2005, the most common reasons for lung transplantation in the United States were: [2]

A lung from a 16-year-old donor would first be offered to the person in the age group 12–17 with the highest lung allocation score and matching blood type in the vicinity of the transplant center. If there no suitable recipient in that age group, it would next be offered to the highest LAS-scoring candidate who is under 12 years of age.
A novel approach to organ transplantation allowed patients to wean off anti-rejection drugs after two years, according to the results of a phase 3 clinical trial presented Monday.
Rejection mediated by T lymphocytes sensitized by direct allorecognition pathway is predominant in the short period after the transplantation, but usually subsides with depletion of passenger cells while indirect recognition contributes to continuing graft damage and plays role in chronic rejection.
Anti-thymocyte globulin (ATG) is an infusion of horse or rabbit-derived antibodies against human T cells and their precursors , which is used in the prevention and treatment of acute rejection in organ transplantation and therapy of aplastic anemia due to bone marrow insufficiency.
ABO-incompatible (ABOi) transplantation is a method of allocation in organ transplantation that permits more efficient use of available organs regardless of ABO blood type, which would otherwise be unavailable due to hyperacute rejection.
