[Immunoglobulins and sheep red cell receptors in human lymphoblastoid cell lines simultaneously carrying Epstein-Barr virus and cytomegalovirus genomes].

In this communication we attempt to characterize the principal immunological properties of 3 human lymphoblastoid cell lines (LCL) established in our laboratory which carry both the EBV and CMV genomes. The data obtained suggests that two LCL are representative of B lymphocytes while the other LCL has a mixed cell population with the majority being of the B type. The reasons for this heterogeneity are discussed. It is suggested that CMV may also transform thymus-independent (B) lymphocytes.
