Detailed explanation-1: -Transplant rejection is caused primarily by a cell-mediated immune response to HLA antigens expressed on donor antigen-presenting cells (APCs) transferred along with the transplanted organ.
Detailed explanation-2: -Key components of the innate immune system include leukocytes, dendritic cells, natural killer cells, and plasma proteins-all acting as front-line defenders against pathogens. While innate immunity mounts a general response to any antigen, adaptive immunity responds to specific antigens.
Detailed explanation-3: -Adaptive immunity is initiated when an innate immune response fails to eliminate a new infection, and antigen and activated antigen-presenting cells are delivered to the draining lymphoid tissues.
