Cost-effectiveness of Universal and Targeted Newborn Screening for Congenital Cytomegalovirus Infection.

Importance: Congenital cytomegalovirus (cCMV) infection is a major cause of childhood deafness. Most cCMV infections are not diagnosed without newborn screening, resulting in missed opportunities for directed care.

Objective: To estimate the cost-effectiveness of universal and targeted newborn cCMV screening programs compared with no cCMV screening.

CD1d and CD1c expression in human B cells is regulated by activation and retinoic acid receptor signaling.

B cell activation and Ab production in response to protein Ags requires presentation of peptides for recruitment of T cell help. We and others have recently demonstrated that B cells can also acquire innate help by presenting lipid Ags via CD1d to NKT cells. Given the newfound contribution of NKT cells to humoral immunity, we sought to identify the pathways that regulate CD1 molecule expression in human B cells.
