Monoclonal M6 antibody binds to the surface of murine central nervous system neurons as well as to apical surfaces of epithelial cells in the choroid plexus and proximal tubules of the kidney. M6 antigen is expressed in the central nervous system as early as embryonic day 10, most strongly in the marginal zone of the neural tube, and remains detectable in adulthood. IgG or Fab fragments of M6 antibody interfere with the extension of neurites by cultured cerebellar neurons. Effects of the antibody on neurite extension are readily detectable after 24 h. No reduction of cell viability is detected during the first 3 days of antibody treatment. Cultures maintained in the presence of antibody for longer than 5 days exhibit reduced viability of neurons. This reduction in long-term viability in the presence of M6 antibody is largely avoided when 25 mM KCl is included in the culture medium. The antibody-mediated perturbation of neurite outgrowth is not blocked by the presence of elevated KCl. The unusually short and flattened appearance of neurites in these cultures suggests that the M6 antibody selectively affects neurite extension. Time-lapse cinematography of anti-M6-treated neurons reveals no apparent effect on movement of lamellipodia and filopodia of growth cones. Only the overall extension of the neurite appears to be inhibited. M6 antigen is a 35 kD glycoprotein that can be isolated from a deoxycholate- (DOC) solubilized membrane fraction from adult mouse brain.
