Inhibition of IgE Production in Mice by Non-Specific Suppressor T Cells

Abstract
SWR adult normal splenic T lymphocytes injected into irradiated syngeneic mice along with immune spleen cells can suppress IgE formation by the immune cells. Spleen cells from 1- or 3-week-old mice, however, are not effective in abrogating IgE synthesis. The T lymphocytes which are induced to become suppressors for IgE are hydrocortisone-resistant and anti-thymocyte serum-sensitive. Normal SJL mice, a poor reagin-producing strain, do not appear to have more suppressor cells or cells which are more easily stimulated to become suppressor cells than a good reagin-producing strain (SWR).
