Lymphocytes that develop immunocompetence in the bone marrow are:
a. T lymphocytes
b. B lymphocytes
c. NK cells
d. B and T lymphocytes

검증된 단계별 안내
1
Understand the term 'immunocompetence,' which refers to the ability of lymphocytes to recognize specific antigens and mount an immune response.
Recall that lymphocytes develop immunocompetence in different primary lymphoid organs: T lymphocytes mature in the thymus, while B lymphocytes mature in the bone marrow.
Identify that the question asks specifically about lymphocytes that develop immunocompetence in the bone marrow, so focus on the maturation site of each lymphocyte type.
Recognize that B lymphocytes develop immunocompetence in the bone marrow, whereas T lymphocytes develop it in the thymus, and NK cells do not undergo this specific maturation process in the bone marrow.
Conclude that the correct answer corresponds to the lymphocyte type that matures in the bone marrow, which is B lymphocytes.

질문에 올바르게 답하기 위해 반드시 이해해야 하는 핵심 개념들은 다음과 같습니다.

Immunocompetence

Immunocompetence refers to the ability of lymphocytes to recognize specific antigens and mount an immune response. It is acquired during lymphocyte development in primary lymphoid organs, enabling these cells to distinguish self from non-self molecules.

B Lymphocyte Development

B lymphocytes develop and gain immunocompetence in the bone marrow. During this process, they undergo gene rearrangement to produce unique antigen receptors, preparing them to recognize specific pathogens once they enter circulation.

T Lymphocyte Development

T lymphocytes originate from bone marrow precursors but migrate to the thymus to develop immunocompetence. In the thymus, they undergo selection processes to ensure self-tolerance and functional antigen recognition before entering the bloodstream.
