Puromycin-sensitive aminopeptidase limits MHC class I presentation in dendritic cells but does not affect CD8 T cell responses during viral infections (2008)

Towne, Charles Fenton, York, Ian A., Neijssen, Joost J., Karow, Margaret L., Murphy, Andrew J., Valenzuela, David M., ...

Previous experiments using enzyme inhibitors, cell lysates, and purified enzyme have suggested that puromycin-sensitive aminopeptidase (PSA) plays a role in creating and destroying MHC class...

Analysis of the role of bleomycin hydrolase in antigen presentation and the generation of CD8 T cell responses (2007)

Towne, Charles Fenton, York, Ian A., Watkins, Levi B., Lazo, John S., Rock, Kenneth L.

Long oligopeptides (>10 residues) are generated during the catabolism of cellular proteins in the cytosol. To be presented to T cells, such peptides must be trimmed by aminopeptidases to the proper...

Long oligopeptides (>10 residues) are generated during the catabolism of cellular proteins in the cytosol. To be presented to T cells, such peptides must be trimmed by aminopeptidases to the...

Tripeptidyl peptidase II is the major peptidase needed to trim long antigenic precursors, but is not required for most MHC class I antigen presentation (2006)

York, Ian A., Bhutani, Nidhi, Zendzian, Sophia, Goldberg, Alfred L., Rock, Kenneth L.

Recent reports concluded that tripeptidyl peptidase (TPPII) is essential for MHC class I Ag presentation and that the proteasome in vivo mainly releases peptides 16 residues or longer that require...

Endoplasmic reticulum aminopeptidase 1 (ERAP1) trims MHC class I-presented peptides in vivo and plays an important role in immunodominance (2006)

York, Ian A., Brehm, Michael A., Zendzian, Sophia, Towne, Charles Fenton, Rock, Kenneth L.

CD8(+) T cells respond to short peptides bound to MHC class I molecules. Although most antigenic proteins contain many sequences that could bind to MHC class I, few of these peptides actually...

Leucine aminopeptidase is not essential for trimming peptides in the cytosol or generating epitopes for MHC class I antigen presentation (2005)

Towne, Charles Fenton, York, Ian A., Neijssen, Joost J., Karow, Margaret L., Murphy, Andrew J., Valenzuela, David M., ...

To detect viral infections and tumors, CD8+ T lymphocytes monitor cells for the presence of antigenic peptides bound to MHC class I molecules. The majority of MHC class I-presented peptides are...

A mutant cell with a novel defect in MHC class I quality control (2005)

York, Ian A., Grant, Ethan P., Dahl, A. Maria, Rock, Kenneth L.

COS7 (African Green Monkey kidney) cells stably transfected with the mouse MHC class I allele H-2K(b) were mutagenized, selected for low surface expression of endogenous MHC class I products, and...

The cytosolic endopeptidase, thimet oligopeptidase, destroys antigenic peptides and limits the extent of MHC class I antigen presentation (2003)

York, Ian A., Mo, Annie X. Y., Lemerise, Kristen, Zeng, Wanyong, Shen, Yuelei, Abraham, Carmela R., ...

Most antigenic peptides presented on MHC class I molecules are generated by proteasomes during protein breakdown. It is unknown whether these peptides are protected from destruction by cytosolic...

Evasion of the human cellular immune response by herpes simplex virus (1994)

York, Ian A

Herpes simplex virus (HSV) is unusual in its ability to cause recurrent infection in a host with an ostensibly competent immune system. This thesis describes two mechanisms by which HSV evades the...

Endoplasmic reticulum aminopeptidase 1 (ERAP1) trims MHC class I-presented peptides in vivo and plays an important role in immunodominance

York, Ian A., Brehm, Michael A., Zendzian, Sophia, Towne, Charles F., Rock, Kenneth L.

CD8+ T cells respond to short peptides bound to MHC class I molecules. Although most antigenic proteins contain many sequences that could bind to MHC class I, few of these peptides actually stimulate...
