Quizplus · Accepted Answer

Chronic rejection is associated with fibrosis and scarring of vessel lumens, and can occur months or years after transplantation. This is different from acute rejection, which occurs within days or weeks, and is typically characterized by infiltration of immune cells. Hyperacute rejection is an immediate rejection mediated by pre-existing antibodies, while acute antibody-mediated rejection is a type of acute rejection mediated by donor-specific antibodies. Acute cellular rejection is also a type of acute rejection, but is mediated by T lymphocytes.
