Abstract: The present disclosure relates to a dual enzyme amplification-based colorimetric sensor system for on-site detection of pathogens. The colorimetric sensor system according to the present disclosure may comprise a combination of the CRISPR/Cas12a system with an enzymatic reaction of urease, thereby facilitating on-site detection of pathogens without separate analytical equipment by analyzing the color change through dual enzyme amplification. In addition, it is possible to selectively change the target by changing the crRNA sequence depending on the target pathogen to be detected, which has the advantage of being applicable to various types of pathogens without limitation.

Abstract: The present invention relates to: a novel chimeric antigen receptor containing, as an intracellular signaling domain, an intracellular domain of a receptor containing a dead region; and immune cells expressing the chimeric antigen receptor. In environments in which normal cells are present, the immune cells expressing the chimeric antigen receptor according to the present invention exhibit little or no cytotoxicity and cell death of the immune cells is exhibited, thus ensuring the stability of the normal cells. Conversely, in environments in which target cells are present, the immune cells exhibit more potent cytotoxicity than with conventional techniques utilizing a lone chimeric antigen receptor.

Abstract: Provided is a composition for the prevention or treatment of Hutchinson-Gilford Progeria syndrome (HGPS) using gene editing, which contains sgRNA that hybridizes to mRNA encoding progerin, which causes HGPS, and a gene encoding Cas13 protein acting on the same. When introduced into the cell of a subject to be treated and only the mRNA encoding progerin is selectively cut. There is no need for co-prescribing with other therapies and fewer side effects occur than traditional farnesyltransferase inhibitors (FTIs). The efficiency is higher than when treated using homologous recombination (HR) at the DNA level, treatment using composition can be made reversibly, and the composition can be applied specifically compared to targeted treatment using RNAi (RNA interference), and has fewer side effects. Compared to treatment using CRISPR/Cas9, which directly acts on DNA and produces irreversible results, treatment using composition is reversible and selectively cut only mRNA encoding progerin, thereby ensuring safety.

Abstract: The present invention relates to a novel signal sequence peptide and a vector comprising a polynucleotide encoding same. The signal sequence peptide can induce a protein linked thereto to be secreted to the outside of a cell, and thus, when the signal sequence peptide is used or a recombinant microorganism transformed with the vector is used, the signal sequence peptide expresses a target protein and then secretes the target protein to the outside of a cell, thus enabling the target protein to exhibit the activity and function thereof.
