Surface immunoglobulins and lymphocyte adhesiveness during development.
Surface immunoglobulins and lymphocyte adhesiveness were studied in 86 children divided according age into six groups. The percentages of B lymphocytes in newborns and older children were similar, but spontaneous lymphocyte adhesiveness in newborns was much lower. The group of one-year-old children had distinctly lower percentages of lymphocytes with surface immunoglobulins of the I gA + IgM / IgG classes compared with all the other developmental groups.
