What is the preferred preoperative source of T and B lymphocyte isolation in a cadaveric donor receiving multiple blood transfusions?

• A. Axillary nodes
• B. Bone marrow
• C. Inguinal nodes
• D. Peripheral blood

Answer: (C)

The preferred preoperative source of T and B lymphocyte isolation in a cadaveric donor receiving multiple blood transfusions is peripheral blood. This choice is based on the fact that in situations where a donor has received multiple transfusions, lymphocytes from the lymphoid tissues such as lymph nodes or bone marrow may be compromised or altered due to the immunomodulatory effects of the transfusions. In general, peripheral blood contains a mix of lymphocytes that can still represent a diverse immune repertoire, including those that might react differently in the context of organ transplantation. Additionally, peripheral blood can be more readily accessed for sampling without the need for more invasive procedures that might be associated with obtaining tissues from nodes or bone marrow. While axial or inguinal lymph nodes and bone marrow can yield lymphocytes, they may be less optimal when considering the influence of multiple transfusions on the quality and functionality of these cells. Hence, peripheral blood is often favored for its ability to provide a more representative population of T and B lymphocytes that remain useful for transplantation protocols.
