Sercarzian immunology - In memoriam. Eli E. Sercarz, 1934-2009

► “Immunologic paralysis” is due to a loss of antibody producing cells. ► “Immunologic exhaustion” is the “productive expenditure of immunocytes.” ► The X-Y-Z scheme of immunocyte maturation is an early theory of immunologic memory. ► Hen egg white lysozyme was one of the first well-characterized model antigens. ► “Determinant spreading” is fundamental to our understanding of autoimmunity.
