Popis: | Most primates, including humans, are chronically infected with cospecifically evolved, potentially pathogenic CMV. Abs that bind a 10-aa linear epitope (antigenic determinant 2 site 1) within the extracellular domain of human CMV glycoprotein B neutralize viral infectivity. In this study, we show that genes generated by recombinations involving two well-conserved human germline V elements (IGHV3-30 and IGKV3-11), and IGHJ4, encode primary Ig molecules that bind glycoprotein B at this key epitope. These particular VH, JH, and Vκ genes enable humans to generate through recombination and N nucleotide addition, a useful frequency of primary Igs that efficiently target this critical site on human CMV and thus confer an innate foundation for a specific adaptive response to this pathogen. |
