IMMUNOLOGY. For the article “Short-term antigen presentation and single clonal burst limit the magnitude of the CD8+ T cell responses to malaria liver stages,” by Julius C. R. Hafalla, Gen-ichiro Sano, Luzia H. Carvalho, Alexandre Morrot, and Fidel Zavala, which appeared in number 18, September 3, 2002, of Proc. Natl. Acad. Sci. USA (99, 11819–11824; First Published August 15, 2002; 10.1073/pnas.182189999), the x axis label was omitted from Fig. 1 due to a printer's error. The corrected figure and its legend appear below.
Fig 1.
Persistence of the CD8+ T cell response after a single immunization with sporozoites. Normal mice received transgenic (Tg) CD8+ T cells; 24 h later, they were immunized (♦) i.v. with 5 × 104 attenuated sporozoites or were not immunized (▪). The frequencies of epitope-specific CD8+ T cells in the spleen (Upper) and the liver (Lower) were determined by ELISPOT. Results represent one of two similar experiments expressed as mean values + SD.
