Human umbilical cord mesenchymal stem cell-derived mitochondria (PN-101) attenuate LPS-induced inflammatory responses by inhibiting NFκB signaling pathway.

Inflammation is one of the body's natural responses to injury and illness as part of the healing process. However, persistent inflammation can lead to chronic inflammatory diseases and multi-organ failure. Altered mitochondrial function has been implicated in several acute and chronic inflammatory diseases by inducing an abnormal inflammatory response.

Production and Purification of Recombinant Glucocerebrosidase in Transgenic Rice Cell Suspension Cultures.

Gaucher disease, which is caused by deficiency of glucocerebrosidase (GCD), is currently treated by enzyme replacement therapy. Plant-based systems produce glycoproteins and can be combined with targeting strategies to generate proteins with terminal mannose structures for macrophage uptake. However, the gliding step for the purification is essential since the produced protein still exists inside cells.

Immunogenicity and safety of Vi capsular polysaccharide typhoid vaccine in healthy persons in Korea.

The purpose of this study was to evaluate the immunogenicity and safety of Salmonella Typhi Vi capsular polysaccharide vaccine (Vi vaccine) in Korea. The immunogenicity of a single dose of Vi vaccine was evaluated in 157 subjects (75 children and 82 adults) before and at 1, 6, and 12 months after vaccination. Immunogenicity was measured with a passive hemagglutination assay (PHA), quantified as geometric mean titers (GMTs) and seroconversion rates.

Production and characterization of human CTLA4Ig expressed in transgenic rice cell suspension cultures.

Human cytotoxic T-lymphocyte antigen 4-immunoglobulin (hCTLA4I g) fusion protein, a novel immunosuppressive agent, was expressed in transgenic rice cell suspension culture and its characteristics and in vitro activities were investigated. The expression vector pMYN409 was constructed to express hCTLA4I g under the control of rice alpha-amylase 3D (RAmy3D) promoter. Transgenic calli were prepared by particle bombardment mediated transformation and were screened for hCTLA4I g expression using ELISA.

Characterization of human cytotoxic T lymphocyte-associated antigen 4-immunoglobulin (hCTLA4Ig) expressed in transgenic rice cell suspension cultures.

The avidity for CD80Ig/CD86Ig and the in vitro immunosuppressive effect of recombinant human cytotoxic T lymphocyte-associated antigen 4-immunoglobulin, produced by transgenic rice cell suspension cultures (hCTLA4Ig(P)) with CHO-derived recombinant hCTLA4Ig (hCTLA4Ig(M)), were measured. Surface plasmon resonance (SPR) was used for kinetic binding analysis: hCTLA4Ig(P) and hCTLA4Ig(M) had higher avidity for CD80Ig/CD86Ig than for CD28Ig, and the avidity for CD80Ig/CD86Ig was similar. hCTLA4Ig(P) and hCTLA4Ig(M) had similar in vitro immunosuppressive activity against the expression of T cell-derived cytokines, such as IL-2, IL-4, and IFN-gamma, but did not suppress the expression of macrophage-derived cytokines, including TNF-alpha and IL-1beta, as well as NO.
