NYU School of Medicine pathology researchers solve another mystery in B lymphocyte development
New York May 18, 2009: A new study published online in Nature Immunology ahead of the June 2009 print issue has found that homologous immunoglobulin (lg) alleles pair up in the nucleus at stages that coincide with V(D)J recombination of the heavy and light chain (Igh and Igk) loci. Researche...
