Transplantation of tissues/organs to some patients often fails due to rejection of such tissues/organs by the body of the patient. Which type of immune response is responsible for such rejections?

पर्याय

• Auto-immune response

• Humoral immune response

• Physiological immune response

• Cell-mediated immune response

Answer 1

Cell-mediated immune response

Explanation: 

Organ rejection is caused by cell-mediated immunity (CMI), which is regulated by T cells. The transplanted organ is attacked by the body because it is perceived as foreign. Cyclosporine and other immunosuppressants are used to stop rejection.
