Partitioning cells in a dextran polyethylene glycol aqueous two-phase system (countercurrent distribution, CCD) is a sensitive method for learning about cell surface membrane properties and for subfractionating cell populations. In this study, we subjected lymphocytes from normal DBA/2 mice and autoimmune F1 New Zealand black/New Zealand white [NZB/NZW)F1) mice to countercurrent distribution and found that T cells partition to the right and B cells partition to the left of the CCD curve. We found no difference between the CCD patterns of normal and autoimmune mice. When the murine lymphocytes were exposed to a cationic dietary amino acid (L-canavanine) in vitro, L-canavanine selectively affected the CCD pattern of autoimmune B cells, reflecting an alteration in surface membrane properties. We separated these lymphocytes with altered surface membrane properties by CCD. Impaired B-cell immune responses associated with L-canavanine were isolated to this lymphocyte fraction. This study provides the first evidence that alterations in the charged surface membrane properties are associated with abnormal (auto) immune response.
