In blood donation, an acute hemolytic transv (h9vj eq8f .og)gos4fusion reactoa lskr0y a7x) 4v i *zedyg+.c032ey*hfe1a xion occurs when red blood cells are attacked by the recipient’s immune system. Which property of red blood cells expla*cf+ *xyd7h41zgka0s0 ay3l rox.iv2y ) aeeeins this response?
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 because red blood cells contain c 5rpa, fg8*0zjgy8 l/inf;j-ee hxp)aertain 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 examppy j/a,8)*hji5a- ne0gxz lgf er8 p;fle, if an individual with Type A blood receives a Type B blood donation), the donor’s immune system will recognise those red 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).
