Lev, A., P. Dimberu, S. R. Das, J. C. Maynard, C. V. Nicchitta, J. R. Bennink, and J. W. Yewdell. 2009. Efficient cross-priming of antiviral CD8+ T cells by antigen donor cells is GRP94 independent. J. Immunol. 183: 4205–4210.

Ref. 49 was not cited in the paper. At the end of the first section under Results (Suppression of GRP94 expression does not diminish Ag processing and presentation), the text should read as follows: “Together, these data indicate that GRP94 does not contribute to a rate-limiting step(s) in the generation of either viral or self-peptide-class I complexes or the biogenesis of MHC class I molecules, extending the previous findings of Lammert et al. (49) that GRP94 expression is not required for normal class I expression or CD8+ T cell recognition of allo- or minor H Ags.”

In References, Ref. 49 should be added as follows:

49. Lammert, E., D. Arnold, H. G. Rammensee, and H. Schild. 1996. Expression levels of stress protein gp96 are not limiting for major histocompatibility complex class I-restricted antigen presentation. Eur. J. Immunol. 26: 875–879.

In addition, during copyediting, a series of errors were introduced to the numbering of references. Hence, where the text of the article refers to any reference numbered 37 through 49, the corresponding reference in the References section is lower by one digit. For example, when the text refers to Ref. 39, the reference in the References section is 38.
