Project description:The experiments were carried out to map the ligand binding landscape of various DNA and RNA duplexed aptamer families. Duplexed Aptamer (DA) constructs were engineered from (i) natural and synthetic DNA and RNA aptamers and (i) synthetic oligonucleotide aptamer-complementary elements synthesized on custom DNA microarrays. The aptamers tested consist of the ATP DNA aptamer, the ATP RNA aptamer, the cocaine DNA aptamer, the human alpha-thrombin DNA aptamer, and the natural add riboswitch aptamer from the pathogenic bacteria Vibrio vulnificus. Each duplexed aptamer family consists of 1000's of synthetic constructs, each formed by hybridizing the aptamer with an aptamer-complementary element (ACE) - here, ACEs consisted of various DNA oligonucleotides synthesized as a custom DNA microarray.

Project description:TC-510 is a novel cell therapy that consists of autologous genetically engineered T cells expressing two synthetic constructs: first, a single-domain antibody that recognizes human Mesothelin, fused to the CD3-epsilon subunit which, upon expression, is incorporated into the endogenous T cell receptor (TCR) complex and second, a PD-1:CD28 switch receptor, which is expressed on the surface of the T cell, independently from the TCR. The PD-1:CD28 switch receptor comprises the PD-1 extracellular domain fused to the CD28 intracellular domain via a transmembrane domain. Thus, the switch is designed to produce a costimulatory signal upon engagement with PD-L1 on cancer cells.
