Literatures describing the relation between PDCD1LG2 and anti-tumor immunity in human cancer.

PMID	Cancer type	Relation to immunity	Evidence sentences
26081225	Esophageal Adenocarcinoma	Inhibit immunity (T cell function)	Because the progression from squamous esophagitis to Barrett's esophagus is accompanied by a transition from a TH1 to TH2 immune response, we hypothesized that the TH2 cytokines IL4/IL13 could contribute to PD-L2 induction. We confirmed that these cytokines can augment PD-L2 expression in esophageal adenocarcinoma cell lines.
29361059	Renal Cell Carcinoma	Inhibit immunity	PD-1, PD-L2, CTLA4 and FOXP3, all of which are implicated in the evasion of an anti-tumor immune response, had a significantly higher expression for samples representing co-detection of productive TcR-α and -β recombination reads.
28619999	Head and Neck Squamous Cell Carcinoma	Inhibit immunity; Candidate for immunotherapy target	The prevalence and distribution of PD-L2 correlated significantly with PD-L1 (P= 0.0012-<0.0001); however, PD-L2 was detected in the absence of PD-L1 in some tumor types. Response was greater in patients positive for both PD-L1 and PD-L2 (27.5%) than those positive only for PD-L1 (11.4%). PD-L2 status was also a significant predictor of progression-free survival (PFS) with pembrolizumab independent of PD-L1 status.
16864790	Melanoma	Inhibit immunity	In this study, we created a PDL2-deficient mouse to characterize its function in T cell activation and tolerance. Antigen-presenting cells from PDL2-/- mice were found to be more potent in activation of T cells in vitro over the wild-type controls, which depended on PD-1. Upon immunization with chicken ovalbumin, PDL2-/- mice exhibited increased activation of CD4(+) and CD8(+) T cells in vivo when compared with WT animals. In addition, T cell tolerance to an oral antigen was abrogated by the lack of PDL2.

Content	High-throughput screening data (e.g. CRISPR-Cas9, shRNA and RNAi) for T cell-mediated killing. Genetic screen techniques can identify mechanisms of tumor cell resistance (e.g., PTPN2) and sensitivity (e.g., APLNR) to killing by cytotoxic T cells, the central effectors of anti-tumor immunity. After comprehensively searching, eight groups of screening data sets were collected in the current database. In this tab, users can check whether their selected genes cause resistance or increase sensitivity to T cell-mediated killing in various data sets.

Content	Transcriptomic and genomic profiling of pre-treated tumor biopsies from responders and non-responders to immunotherapy. These data were used to identify signatures and mechanisms of response to checkpoint blockade (e.g., anti-PDL1 and anti-PD1). One example is that mutations in the gene PBRM1 benefit clinical survival of patients with clear cell renal cell carcinoma. After comprehensively searching, we collected 5 and 6 of transcriptomic and genomic data sets, respectively. In this tab, users can check whether their selected genes have significant difference of expression or mutation between responders and non-responders in various data sets. > Expression difference between responders and non-responders > Mutation difference between responders and non-responders
