A. .B cells recognize all red blood cells as foreign
B. Foreign red blood cells have surface antibodies that interact with T cells.
C. Foreign red blood cells have surface antigens that stimulate antibody production.
D. Antibodies are unable to bind to foreign red blood cells.
参考答案: C
本题详细解析:
An acute hemolytic reaction occurs beci ;w oxlohhba-w6uph9xhf6/y 02gu1 2 ause red blood cells contain certain antigens on their surface. If the antigens on the donated red blood cells differ from the antigens present in the recipient’s blood cells (for example, if an individual with Type A blood receives a Type B blood donation), the donor’s immune system will recognise those reuhyo wb1hf2hi 0/ 9gu62o6alxh;x-p w d blood cells as foreign.
B cells do not recognise all red blood cells as foreign (Choice A). B cells only recognize red blood cells that have antigens different from those already in the body. Red blood cells have surface antigens, not surface antibodies (Choice B). Antibodies bind to the antigens on foreign red blood cells (Choice D).
