The coding sequence for TGF-β131 in this expression vector (designated pcDNA-GS-TGF-β131) is preceded by the rat serum albumin leader peptide and the TGF-β1 pro-domain, both of which are required for the proper maturation and secretion of the mature dimer into the culture medium.
Our data showed that DHA can activate inflammasome and induce IL-1β maturation and secretion in breast cancer cells.
In addition, TcES-induced cRAF signaling pathway was critical for down-regulation of the TLR-mediated DC maturation and secretion of IL-12 and TNF-α.
The NLRP3 inflammasome regulates maturation and secretion of IL-1β [32].
This method can be easily adapted to investigate SGs in other cells or tissues, thereby providing a useful tool for elucidating the mechanisms of granule maturation and secretion.
In pathogenic Vibrio cholerae, the DsbA homolog (TcpG) is responsible for the folding, maturation and secretion of virulence factors [27].
D. melanogaster homologs for PC2 (dPC2) and 7B2 (d7B2) have also been identified, and it was demonstrated that dPC2 requires d7B2 for both maturation and secretion [90].
These results suggest that MOMP-vaults can both induce pro-IL-1β synthesis and activate the inflammasome, resulting in the maturation and secretion of increased levels IL-1β.
Inflammasomes are cytoplasmic caspase-1-activating protein complexes that promote maturation and secretion of the proinflammatory cytokines interleukin IL -1β and interleukin IL -1β
We therefore hypothesize that L. casei inhibits vesicle trafficking similar to 3-methyladenine, resulting in impaired maturation and secretion of IP-10 followed by subsequent degradation of the chemokine (Figure 6B).
