Summary For the development of effective prophylaxis (hyperimmune globulins) and improvement of serological testing for human cytomegalovirus (HCMV) infection in immunocompromised patients it is essential to characterize the viral encoded proteins and the humoral immune response in terms of neutralizing antibodies and immunglobulin class and IgG subclass reactivity to “early” and “late” HCMV proteins. The major neutralizing epitopes have been identified and screening of donor sera for neutralizing antibody by either conventional neutralization assays or enzyme-linked immunosorbent assay using recombinant antigens may help to improve the efficacy of hyperimmune globulin prophylaxis. The humoral response to individual HCMV proteins has been thoroughly investigated in immunocompromised patients. Antibodies against HCMV induced “early” antigens are not exclusively associated with active infection but may indicate an elevated risk for cytomegalic inclusion disease in immunocompromised patients. With a sensitive western blot technique. IgM and IgA antibodies against HCMV “late” proteins can be detected in sera from healthy seropositive individuals. Serum samples from subjects suffering from cytomegalic inclusion disease show significantly larger broader immune responses compared with healthy HCMV antibody carriers. Promising results using recombinant antigens corresponding to immunodominant epitopes for the detection of HCMV specific antibodies have been published.
