We investigated the effect of inactivated Bifidobacterium on the mRNA expression of TRAF6, GSK-3β, and microRNA-146a in lipopolysaccharide (LPS)-stimulated rat small intestinal epithelial cells (IEC-6s). IEC-6s were randomly divided into an LPS group, a culture supernatant group, and an inactivated bacteria group. After stimulation with LPS for 5 h, the three groups were treated as follows: the...
Background and purpose: So far many protein factors capable of inhibiting the immune system are secreted by different cancer cell lines in the culture supernatant and characterized. Ïn this report, the release of DNÂ fragments into the culture supernatant of human promyelocytic cell line, HL-60, with immunosuppressive activity was investigated. Materials and methods : HL-60 culture supern...
BACKGROUND Protein aggregation during monoclonal antibody (mAb) production can occur in upstream and downstream processing (DSP). Current methods to determine aggregate formation during cell culture include size exclusion chromatography (SEC) with a previous affinity chromatography step in order to remove disturbing cell culture components. The pre-purification step itself can already influence...
A culture supernatant of concanavalin A-activated spleen cells (Con A supernatant) induced murine macrophages to express Ia antigens in vitro. Biochemical characterization of the Con A supernatant indicated that the macrophage Ia antigen regulatory activity shares molecular weight, pI, and hydrophobic and affinity characteristics with immune interferon (IFN-gamma). Antiserum to mouse IFN-gamma ...
