title: Effect of ageing on surface IgG of human peripheral lymphocytes.
abstract: An increase in the percentage of IgG bearing peripheral blood lymphocytes is observed in aged subjects as compared with young ones. Such a finding is probably due to the presence, in 'aged' sera, of a higher concentration of immune complexes, bound to lymphocytes through their Fc or Complement receptors.
