A METHOD FOR CD4+ T-CELL EPITOPE PREDICTION USING ANTIGEN STRUCTURE

NºPublicación: US2018247011A1 30/08/2018

Solicitante:
THE ADMINISTRATORS OF THE TULANE EDUCATIONAL FUND [US]

Resumen de: US2018247011A1

The present invention relates to novel methods of diagnosing, preventing, and treating diseases, disorders, and infections relating to T-cell response. The disclosed methods for predicting MHC class II epitopes that elicit CD4+ T-cell response are N based on the three-dimensional protein structure of an antigen of interest. Given such an antigen, structural properties of the protein taken from experimental and modeling data are used to compute an epitope likelihood score that characterizes the location of epitopes likely to elicit an immune response to CD4+ T-cells. The epitopes are then used to construct biomolecules, including peptides, which may be used to diagnose, prevent, and/or treat a number of diseases, disorders, and infections.

METHODS TO ENHANCE TUMOR-TARGETING BY BACTERIA

NºPublicación: US2018236011A1 23/08/2018

Solicitante:
ANTICANCER INC [US]

Resumen de: US2018236011A1

Methods using chemotherapy drugs promote targeting of S. typhimurium A1-R of melanoma, thereby enhancing efficacy against the melanoma PDOX. A metastatic melanoma obtained from the right chest wall of a patient was previously established orthotopically in the right chest wall of nude mice as a patient-derived orthotopic xenograft (PDOX) model. We previously showed that the combination of tumor targeting Salmonella typhimurium A1-R (S. typhimurium A1-R) and chemotherapy was highly effective against the melanoma PDOX. In the present study, we investigated the mechanism of the high efficacy of this combination. Combination therapy significantly increases S. typhimurium A1-R tumor targeting alone (S. typhimurium A1-R+TEM: p<0.01, S. typhimurium A1-R+VEM: p<0.01).
