Peptide Repertoire Changes Caused by Defects in Antigen ProcessingByKristin Camfield LindDoctor of Philosophy in Molecular and Cell BiologyUniversity of California, BerkeleyProfessor Nilabh Shastri, ChairMHC I molecules display peptides derived from intracellular proteins on the cell surface for recognition by CD8+ T cells. Presentation of these peptide:MHC I complexes (pMHC I) is important for elimination of viruses and transformed cells. In order to generate an effective CD8 T cell response, a high-quality set of pMHC I must be presented. However, the editing mechanisms that select these optimal pMHC I are not clear. In these studies, we used biochemical and immunological methods to examine the role of two ER-resident pMHC I editors, tapasin and ERAAP in shaping the pMHC I repertoire. Analysis of tapasin-deficient mice revealed a qualitative loss as well as gain of some pMHC I. However, these changes did not overlap with the ERAAP-unedited pMHC I repertoire, indicating that tapasin edits peptides in a distinct way. Sequencing of peptides unique to tapasin-deficient cells revealed altered C-termini, suggesting that tapasin determines the peptide C-terminus while ERAAP shapes the peptide N-terminus. We separately examined the allele-specific effects of ERAAP-deficiency on the H-2d pMHC I repertoire. In addition to Kd and Dd, these mice express Ld, an MHC I molecule which is particularly affected by loss of ERAAP. We found that ERAAP-deficiency has distinct effects on the peptide repertoire presented by each MHC I molecule. Analysis of the peptide sequences revealed unique peptides bound to all three MHC I, although long, structurally unique peptides were only found on Dd and Kd. Furthermore, using a T cell hybridoma specific for loss of ERAAP function, we identified and characterized an ERAAP-unedited peptide presented by Dd. Together, these findings highlight the importance of both tapasin and ERAAP in determining an optimal pMHC I repertoire.

Effective CD8+ T cell responses depend on presentation of a stable peptide repertoire by MHC class I (MHC I) molecules on the cell surface. The overall quality of peptide-MHC I complexes (pMHC I) is determined by poorly understood mechanisms that generate and load peptides with appropriate consensus motifs onto MHC I. In this article, we show that both tapasin (Tpn), a key component of the peptide loading complex, and the endoplasmic reticulum aminopeptidase associated with Ag processing (ERAAP) are quintessential editors of distinct structural features of the peptide repertoire. We carried out reciprocal immunization of wild-type mice with cells from Tpn- or ERAAP-deficient mice. Specificity analysis of T cell responses showed that absence of Tpn or ERAAP independently altered the peptide repertoire by causing loss as well as gain of new pMHC I. Changes in amino acid sequences of MHC-bound peptides revealed that ERAAP and Tpn, respectively, defined the characteristic amino and carboxy termini of canonical MHC I peptides. Thus, the optimal pMHC I repertoire is produced by two distinct peptide editing steps in the endoplasmic reticulum. [ABSTRACT FROM AUTHOR]

- Abstract
The transcription factors E2 A and HEB (members of the E protein family) have been shown to play essential roles in lymphocyte development, while their negative regulators, the Id proteins, have been implicated in both lymphocyte development and in the CD8
+ T-cell immune response. Here, we show that E proteins also influence CD8+ T cells responding to infection. E protein expression was upregulated by CD8+ T cells during the early stages of infection and increased E protein DNA-binding activity could be detected upon TCR stimulation. Deficiency in the E proteins, E2 A and HEB, led to increased frequency of terminally differentiated effector KLRG1hi CD8+ T cells in mice during infection, and decreased generation of longer-lived memory-precursor cells during the immune response. These data suggest a model whereby E protein transcription factor activity favors rapid memory-precursor T-cell formation while their negative regulators, Id2 and Id3, are both required for robust effector CD8+ T-cell response during infection.

During infection, naive CD8
+ T cells differentiate into effector cells, which are armed to eliminate pathogens, and memory cells, which are poised to protect against reinfection. The transcriptional program that regulates terminal differentiation into short-lived effector-memory versus long-lived memory cells is not clearly defined. Through the use of mice expressing reporters for the DNA-binding inhibitors Id2 and Id3, we identified Id3hi precursors of long-lived memory cells before the peak of T cell population expansion or upregulation of cell-surface receptors that indicate memory potential. Deficiency in Id2 or Id3 resulted in loss of distinct CD8+ effector and memory populations, which demonstrated unique roles for these inhibitors of E-protein transcription factors. Furthermore, cytokines altered the expression of Id2 and Id3 differently, which provides insight into how external cues influence gene expression. [ABSTRACT FROM AUTHOR]- Published
