主 题:lymphocytes lymphoid complexes
摘 要:B lymphocytes are vital components of vertebrate adaptive immune ***,B-cell dysfunction can promote autoimmunity and immunodefi-ciency,and errors in development can cause B-lineage lymphoid malignancies.B-cell development requires RAG1/RAG2(RAG)endonuclease-mediated assembly of immunoglobulin(Ig)*** assembly of Ig heavy chain(IgH)genes in G1-phase pro-B cells produces IgH proteins that pair with VpreB/λ5 to form pre-B-cell receptor(pre-BCR)*** pro-B cells,pre-BCR signaling inhibits Rag1/Rag2 transcription,stabilizes Cyclin D3 to drive cellular proliferation and promotes differentiation of large pre-B cells.
