NY-ESO-1 protein:
NY-ESO-1 (123-137) DRB1*04:01 is an epitope analogue of the New York esophageal squamous cell carcinoma-1, also named cancer testis. NY-ESO-1 is expressed in 82% of neuroblastomas and 46% of melanomas but also in many others solid tumors and hematological malignancies.

Results of studies suggest after stimulation of NY-ESO-1 (123-137) DRB1*04:01 specific T cells and IFN- ELISPOT and chronium release assays that NY-ESO-1 (123-137) DRB1*04:01 can be an immunogenic epitope encoded by NY-ESO-1. NY-ESO-1 (123-137) DRB1*04:01 contains epitope capable of binding HLA-DR molecules.

Peptide YY (PYY) is a peptide hormone that inhibits gastric emptying and increases intestinal transit time. This peptide can be given as an intubation, perfusion, or intravenous infusion to increase the absorption of nutrients. It also has the potential to reduce body weight in obese people. PYY is a potent activator of protein synthesis and it has been shown to stimulate lipolysis in adipocytes. PYY is found in the ileum and colon, where it may have its effects on appetite suppression and regulation of gastrointestinal motility.

Ovalbumin protein:
OVA 257-264 (H-2Kb) is an epitope of interest of the egg white albumen, ovalbumin. Ovalbumin is a glycoprotein that is sufficiently large and complex to be mildly immunogenic. Indeed, it has been demonstrated that Ovalbumin contains B-cell epitopes which are recognized by specific IgE antibodies and CD4 T cell epitopes restricted by the MHC I-Ad molecule in mice and by HLA-D molecule in human.
Applications of OVA 257-264:
OVA 257-264 is used to stimulate T cells in PBMCs and to quantify peptide epitope specificity and IFN-γ releasing effector cells by ELISPOT assay. OVA 257-264 is also used to test new adjuvant in immunotherapeutic vaccine development. OVA 257-264 can form a stable hydrogel and stimulate a immune response. This reaction seems to be linked with OVA 257-264 property to self-assemble into a hydrogel.

Somatostatin is a peptide hormone that is produced by the hypothalamus and inhibits the release of growth hormones, stimulates the release of insulin from the pancreas, and inhibits the release of glucagon from the pancreas. Somatostatin also has biological properties that inhibit neuronal death in combination therapy groups. It has been shown to have cell factor activity which may contribute to its antitumor activity. Somatostatin also has pro-apoptotic properties in vitro assays at physiological levels, making it an excellent target for cancer therapy.
