Astrocytes, oligodendrocytes, and Schwann cells share a common antigenic determinant that cross-reacts with myelin basic protein: identification with monoclonal antibody
T Brenner, RP Lisak, A Rostami, DE Pleasure and DH Silberberg
We have produced a monoclonal antibody against myelin basic protein that
reacts with astrocytes, oligodendrocytes, and Schwann cells. This antibody
was generated by fusion of mouse myeloma cells with spleen cells from
BALB/c mice immunized with delipidated white matter from adult rat corpus
callosum. The antibody was characterized via solid- phase radioimmunoassay,
immunoblot of SDS-PAGE, and by indirect immunofluorescence staining of
monolayer cultures containing oligodendrocytes, astrocytes, and Schwann
cells. Myelin basic protein (MBP) was shown previously to be present only
in myelin producing cells in CNS and PNS (oligodendroglia and Schwann
cells) and not in astrocytes. The binding of this monoclonal antibody to
all 3 cell types suggests that these cells share a common epitope. This
epitope may be related to a common progenitor cell.
