CIRCULATING SPECIFIC IgA IMMUNE COMPLEXES ACTIVATING COMPLEMENT IN HEALTHY PERSONS / 中国免疫学杂志

ABSTRACT

plexes activating complement of 404 cases of healthy persons.It was found that there were thisimmune complexes in every case except umbilical blood,the amount of this immune complexeswere related to age and sex,but not to ABO blood types,which was similar to the relationshipbetween serum IgA and age and sex.These results suggests that the amount of circulating spe-cific IgA immune complexes activating complement in healthy persons depend chiefly on the levelof serum IgA,detecting this immune complexes may approach some characterizations on normalimmune response,and age and sex should be considered when normal value of the specific im-mune complexes is determined
