TCR affinity defines tumor-specific CD8 T cell differentiation and dysfunction [RNA-seq]

Default Boolean Operator: Terms in a search string will be connected by the AND operator, EXAMPLE: searching genomic melanoma will produce the same results as genomic AND melanoma .
AND, OR, NOT: Combine terms in a search with the boolean operators AND (to add specificity), OR (to broaden), or NOT (to eliminate a term). Operators must be capitalized (all other search terms are not case-sensitive).
Wild Card: Add wild card symbols * (open-ended) and ? (single character) to truncate terms. EXAMPLE: searching gen* shows results for 'gene', 'genetic', 'genomic, etc. Searching gene? returns results for 'gene' or 'genes' but not for 'genome'.
Phrase Searching: Enclose search in quotation marks "keyword or search term" to search for an exact phrase. EXAMPLE: "transcription factors" returns results for records where transcription is immediately followed by the word factors .
Diacritics: Words containing diacritics translate those characters to non-diacritic form. EXAMPLE: massague returns results for Massague&#769 .
Filter by: Located on the homepage (left panel), use filters to search for records or narrow the search. From search results page, filters can be removed by clicking on the term at the top of the page.

Description: Summary from GEO:

"RNA-seq analysis of tumor-specific CD8 T cells encountering tumor antigens with varying TCR/pMHC affinity."

Overall design from GEO:

"Transgenic antigen-specific CD8 T cells were adoptively transferred into tumor-bearing mice, isolated and flow-sorted from tumor draining lymph nodes and tumors at distinct time points post transfer for subsequent RNA-seq analysis. MCA 205 tumor cell lines were generated to express a defined tumor-specific model antigen, SV40 large T antigen epitope-I (TAG), as altered peptide ligands (APL), recognized by antigen-specific TCR SV40-I CD8 T cells with varying affinities (high-affinity N4, intermediate affinity F6, and low affinity D4 APL). TAG-specific effector CD8 T cells isolated during acute Listeria infection were used as controls."
