Question

Transplantation of tissues/organs fails often due to non-acceptance by the patient's body. Which type of immune-response is responsible for such rejections?

Options

• Hormonal immune response

• Physiological immune response

• Autoimmune response

• Cell-mediated immune response

Answer 1

Cell-mediated immune response

Explanation:

T cells recognise transplanted tissue as non-self and can attack it, producing graft rejection. This is a cell-mediated response, not a hormonal, physiological or autoimmune response.
