IL-24 intrinsically regulates Th17 cell pathogenicity in mice. J Exp Med 2022; 219:213347. [PMID: 35819408 PMCID: PMC9280194 DOI: 10.1084/jem.20212443] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/08/2021] [Revised: 05/03/2022] [Accepted: 06/14/2022] [Indexed: 11/16/2022] Open
Abstract
In certain instances, Th17 responses are associated with severe immunopathology. T cell–intrinsic mechanisms that restrict pathogenic effector functions have been described for type 1 and 2 responses but are less well studied for Th17 cells. Here, we report a cell-intrinsic feedback mechanism that controls the pathogenicity of Th17 cells. Th17 cells produce IL-24, which prompts them to secrete IL-10. The IL-10–inducing function of IL-24 is independent of the cell surface receptor of IL-24 on Th17 cells. Rather, IL-24 is recruited to the inner mitochondrial membrane, where it interacts with the NADH dehydrogenase (ubiquinone) 1 α subcomplex subunit 13 (also known as Grim19), a constituent of complex I of the respiratory chain. Together, Grim19 and IL-24 promote the accumulation of STAT3 in the mitochondrial compartment. We propose that IL-24–guided mitochondrial STAT3 constitutes a rheostat to blunt extensive STAT3 deflections in the nucleus, which might then contribute to a robust IL-10 response in Th17 cells and a restriction of immunopathology in experimental autoimmune encephalomyelitis.

J Ind Microbiol Biotechnol 2020; 47:83-96.

Abstract
A method called Cas-3P allowing for immediate, multiplexed and sequential genome engineering was developed using one plasmid expressing Cas9 and three marked plasmid backbones (P1, P2 and P3) for guide RNA (gRNA) expression. The three marked gRNA plasmid backbones were recurred in a P1-P2-P3 order for sequential gene targeting, without construction of any additional plasmid and elimination of gRNA plasmid by induction in each round. The efficiency of direct gRNA plasmid curing mediated by Cas-3P was more than 40% in sequential gene targeting. Besides, Cas-3P allowed single-, double- and triple-loci gene targeting with an efficiency of 75%, 36.8% and 8.2% within 3-4 days, respectively. Through three sequential rounds of gene targeting within 10 days, S. cerevisiae was optimized for the production of patchoulol by replacing one promoter, overexpressing three genes and disrupting four genes. The work is important for practical application in the cell factory engineering of S. cerevisiae.

[PMID: 31170524 DOI: 10.1016/j.mito.2019.05.007] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/10/2019] [Revised: 05/23/2019] [Accepted: 05/30/2019] [Indexed: 02/05/2023]
Abstract
Pyridine Nucleotide-Disulphide Oxidoreductase Domain 2 (PYROXD2), a Hepatitis B virus X protein (HBx)-interacting protein, is significantly down-regulated in hepatocellular carcinoma (HCC), however its exact biological function remains unclear. The aim of this study is to investigate the subcellular localization and biological function of PYROXD2 in hepatic cells. The results showed that PYROXD2 was imported to the mitochondrial inner membrane/matrix by Tom40 and Tim23, but not Mia40. PYROXD2 151-230aa might be the mitochondrial targeting sequence. PYROXD2 interacted with complex IV subunit COX5B. Knockout of PYROXD2 decreased MMP, intracellular ROS, complex IV activity, cell proliferation, ATP content and mtDNA copy number, but increased mtROS levels and the number of immature mitochondria. In summary, our data illustrated that PYROXD2 localizes to the mitochondrial inner membrane/matrix, and it plays important roles in regulating mitochondrial function.

Abstract
OBJECTIVES To test the applicability of Cpf1 from Francisella novivida in genomic integration of in vivo assembled DNA parts in Saccharomyces cerevisiae. RESULTS An easy-to-use vector toolkit, containing a CEN6/ARS4 plasmid expressing Cpf1 from Francisella novivida (FnCpf1) and a 2 μ plasmid for crRNA or crRNA array expressing, was constructed for Cpf1-assisted genomic integration in S. cerevisiae. Our results showed that FnCpf1 allowed for targeted singleplex, doubleplex, and tripleplex genomic integration of in vivo assembled DNA parts with efficiencies of 95, 52, and 43%, respectively. CONCLUSIONS CRISPR-Cpf1 system allows for efficient genomic integration of in vivo assembled DNA parts in S. cerevisiae, and thus provides an alternative CRISPR-Cas method for metabolic pathway engineering in addition to CRISPR-Cas9 system previously reported for yeast.
