  • Title: Appearance of receptors for Macaca speciosa red blood cells on human fibroblasts transformed by simian virus 40.
    Author: Curry RA, Pellegrino MA, Saxton RE, Jensen F, Ferrone S.
    Journal: J Immunol; 1980 Nov; 125(5):2017-9. PubMed ID: 6253561.
    Abstract:
    Receptors for monkey red blood cells (MRBC) that are expressed on subpopulations of human lymphoid cells are coded by genes linked to the major histocompatibility complex (MHC) region. Since malignant transformation of cells is associated with changes in structures coded by the MHC region, 10 cultured human melanoma and sarcoma cells and autologous SV40-transformed fibroblasts were tested for expression of MRBC receptors and compared with normal autologous fibroblasts. Only 2 of the tumor cell lines and normal fibroblasts from the same individual formed rosettes with MRBC. On the other hand, SV40 transformation induced in all the fibroblasts expression of receptors for MRBC. MRBC receptors on SV40-transformed fibroblasts show properties similar to those on B lymphoid cells.
