THE ROLE OF SPECTRIN AND ACTIN IN IRREVERSIBLY SICKLED CELLS: UNSICKLING OF “IRREVERSIBLY” SICKLED GHOSTS BY CONDITIONS WHICH INTERFERE WITH SPECTRIN-ACTIN POLYMERIZATION11These studies were supported by research grants HL-15963 and HL-15157 and contract no. HB-4–2973 from the National Institutes of Health. The work was done during the tenure of an Established Investigatorship of the American Heart Association (Dr. Lux).
