Patent number: 11230575Abstract: Disclosed is a method of producing an antimicrobial peptide wherein an antimicrobial peptide gene is fused with a green fluorescent protein gene expressed insolubly in E. coli, followed by introduction into E. coli, expression, and removal of the green fluorescent protein to yield the antimicrobial peptide. This method is capable of producing the antimicrobial peptide with high yield in a simple and economical manner and is thus effective at providing native antibiotics that can replace conventional antibiotics in pharmaceutical and feed industries, requiring the development of antibiotics having a new mechanism of action that can eradicate resistant strains due to the proliferation of multiple-drug-resistant microorganisms. Furthermore, the use of an amino acid cleavage process through acid treatment, instead of using conventional cyanogen bromide, is cost-effective for the purification of a target protein from an insoluble protein, can decrease the risk of processing, and enables rapid processing.Type: GrantFiled: February 26, 2016Date of Patent: January 25, 2022Assignee: Konkuk University Industrial Cooperation CorpInventor: Chan Kyu Park

Patent number: 11124551Abstract: Described herein is a novel, mitochondrial encoded, open reading frame, that leads to the production of a new mitochondrial peptide. Residing within the ND-Two subunit, a specific small nucleotide polymorphism disrupts expression of this mitochondrial peptide, and is correlated with an increase in obesity and diabetes, particularly in certain ethnic populations. In vitro administration of the peptide increases insulin secretion, decreases fat accumulation and improves glucose uptake in muscle cell. Antibodies generated against the peptide can be used for detecting peptide deficiency, in addition to SNP detection, supporting diagnostic approaches. In vivo studies further revealed that administration of the peptide improves glucose tolerance, thereby providing a new therapeutic avenue for a novel diabetes therapy and decreases bodyweight, thus serving as a novel obesity therapy. Generation of synthetic analogs further enhance or abrogated activity relative to the natural peptide.Type: GrantFiled: June 23, 2017Date of Patent: September 21, 2021Assignee: UNIVERSITY OF SOUTHERN CALIFORNIAInventors: Pinchas Cohen, Kelvin Yen

Patent number: 9453217Abstract: Antigen-specific immunoglobulin V-regions are identified from a library of nucleic acids amplified using polymerase chain reaction using leader sequence-specific forward primers. The use of leader sequence primers allows all V-region sequences to be amplified (including those with extensive 5? end mutations) without loss of the original 5? V gene segment sequence. These libraries can be screened for antigen-specific V-regions using eukaryotic cells engineered to express the amplified V-region-encoding nucleic acids or using bacterial phage display techniques. In the latter, a second V-region library is made using a larger than conventional set of 5? V-region primers. The sequence errors introduced into the amplification products by this method are corrected using sequence information obtained in the products amplified by the V-region primers to screen the library created using the leader sequence primers.Type: GrantFiled: November 12, 2015Date of Patent: September 27, 2016Assignee: XBIOTECH, INC.Inventor: John Simard

KIT FOR MONITORING IMMUNE STATUS AFTER TRANSPLANT AND METHOD FOR MONITORING IMMUNE STATUS USING SAME
Publication number: 20150051108Abstract: The present invention relates to a method and a kit for monitoring an immune status after transplant. The kit for monitoring an immune status after transplant and the method for monitoring an immune status of an individual after transplant as provided in the present invention make it easy and accurate to determine an immune status in the individual after transplant and thus have an effect of reducing overuse of an immunosuppressive agent prescribed after transplant and also have an effect of conveniently managing an immune status of each patient.Type: ApplicationFiled: November 7, 2014Publication date: February 19, 2015Inventors: Mi-La CHO, Chul-Woo YANG, Jong-Young CHOI, Joo-Yeon JHUN, Hee-Yeon KIM, Jae-Kyeong BYUN, Ye-Been YIM, Byung-Ha CHUNG, Kyoung-Woon KIM -
Publication number: 20150052626Abstract: The invention provides cells or populations of cells, including non-human animals or non-human mammals having these cells, where the cells or populations of cells are stably tagged, uniquely identified and genetically barcoded by one or more detectable, e.g., fluorescent, proteins; and methods of making and using them. In alternative embodiments, the invention provides methods for tagging, uniquely identifying or genetically barcoding a cell, a population of cells, or a culture of cells by stably transferring, transfecting, transducing, infecting or implanting one or more nucleic acids encoding readable or detectable, e.g., fluorescent, moieties into the cells. In alternative embodiments, the nucleic acids are stably inserted into the cells such that the readable or detectable, e.g., fluorescent, genetic barcoding becomes a stable, heritable characteristic of the cell.Type: ApplicationFiled: August 18, 2014Publication date: February 19, 2015Inventor: Roland WOLKOWICZ

Publication number: 20150045253Abstract: The invention relates to a method for determining the ability of a candidate antibody to keep a first cell and a second cell close to one another, said method comprising the following steps: bringing said candidate antibody in contact with (i) a first cell expressing, in the extracellular portion of its plasma membrane, a first protein that is known to be or is suspected of being recognized by the candidate antibody and (ii) a second cell expressing, in the extracellular portion of the plasma membrane, a second protein that is also known to be or suspected of being recognized by the candidate antibody, each of the proteins being labeled with a member of a pair of FRET partners, and measurement of the FRET signal and comparison with the signal measured in the absence of the candidate antibody. The invention also relates to a reagent kit for carrying out this method.Type: ApplicationFiled: March 18, 2013Publication date: February 12, 2015Inventor: Delphine Jaga
