| Abstract: | Bacterial lipopolysaccharide (LPS) from Escherichia coli labelled with tritium has been used to follow the binding of LPS to lymphocytes. Binding to cells rose to a maximum 2-7 min after addition of [3H]-LPS, followed by loss of [3H]-LPS from cells, reducing to about 10% of the peak level at 20-30 min. Peripheral blood lymphocytes, mesenteric lymph node and thymus cells of the pig and CBA, C3H/He and C3H/HeJ mouse spleen cells all bound [3H]-LPS transiently at similar levels. It is concluded that this type of LPS binding cannot be solely responsible for the preferential stimulation of B cells by LPS. |
