Modulation of novel immune checkpoint targets

PendingUS20190255107A1Decrease in exhausted T cell phenotypeIncrease T cell activationAntibacterial agentsCell receptors/surface-antigens/surface-determinantsDiseaseClinical efficacy
Dysfunctional or exhausted T cells arise in chronic diseases including chronic viral infections and cancer, and express high levels of co-inhibitory receptors. Therapeutic blockade of these receptors has clinical efficacy in the treatment of cancer. While co-inhibitory receptors are co-expressed, the triggers that induce them and the transcriptional regulators that drive their co-expression have not been identified. The immunoregulatory cytokine IL-27 induces a gene module in T cells that includes several known co-inhibitory receptors (Tim-3, Lag-3, and TIGIT). The present invention provides a novel immunoregulatory network as well as novel cell surface molecules that have an inhibitory function in the tumor microenvironment. The present invention further provides the novel discovery that the transcription factors Prdm1 and c-Maf cooperatively regulate the expression of the co-inhibitory receptor module. This critical molecular circuit underlies the co-expression of co-inhibitory receptors in dysfunctional T cells and identifies novel regulators of T cell dysfunction.

The present invention relates to a promoter system inducing expression of 3-hydroxypropionic acid (3-HP) and a method of biologically producing 3-HP using the same. To improve production of 3-HP in a biological manner, continuous synthesis of new enzymes having enzyme activity is necessary. As a result of screening 3-HP reactive transcription regulators and 3-HP reactive promoters from several microorganisms including Pseudomonas denitrificans, it was confirmed that the transcriptions regulations and promoters are composed of LysR proteins and particular gene nucleotide sequences binding to the LysR proteins. Therefore, the 3-HP inducible system is expected to be effectively used to regulate 3-HP metabolic pathways.
