Extracellular Vesicles of Streptococcus anginosus Mediate Gastritis via Epithelial Barrier Disruption and Macrophage‐driven Inflammation

Advanced Science, EarlyView.
Streptococcus anginosus extracellular vesicles (SA‐EVs) accumulate in gastric tissue, disrupt epithelial tight junctions, and induce gastritis characterized by neutrophil infiltration and elevated cytokines (TNF‐α, IL‐6, IL‐17A). Proteomics identifies TMPC and FBP62 as key SA‐EVs virulence factors; their genetic deletion attenuates inflammation ...

Divergent Regulatory Effects of Jasmonic Acid on Tomato Lycopene Biosynthesis Under Light and Dark Conditions

Advanced Science, EarlyView.
This study reveals the mechanism by which jasmonic acid (JA) regulates lycopene synthesis under light and dark conditions. In light, JA activates SlMYC2, which suppresses SlPIF1a and promotes SlPSY1 expression. In darkness, JA induces the acetyltransferase SlNATA1, which acetylates the dark‐accumulated SlPIF1a, thereby repressing SlPSY1 expression ...

Fibrates Inhibit PLTP‐induced M2 Macrophage Infiltration and Increase the Sensitivity of Hepatocellular Carcinoma to ICIs

Advanced Science, EarlyView.
Phospholipid transfer protein(PLTP) plays a critical role in forming a complex with kinase A (AURKA) and P65. This interaction facilitates phosphorylation of P65 at Ser536, leading to the activation of the NF‐κB signaling pathway. Ultimately, this leads to the upregulation of downstream cytokines, including IL‐6, IL‐8, and CSF‐1, which promotes M2 ...

Protein Translocation Across Membranes

Science, 1988
Many newly synthesized proteins must be translocated across a membrane to reach their final destinations. Translocation requires a signal on the protein itself, a loose conformation of the protein, energy, and receptor-like components in the cytosol and on the target membrane.

Protein translocation into mitochondria

BioFactors, 1998
AbstractThe mitochondrial membranes contain translocation machineries (“preprotein translocases”) which facilitate transport of proteins from the cytosol into the mitochondria. The TOM complex is localized in the outer membrane. Two translocases have been characterized in the inner membrane: the Tim23‐Tim17 complex and

Twin-Arginine Protein Translocation

2016
Twin-arginine protein translocation systems (Tat) translocate fully folded and co-factor-containing proteins across biological membranes. In this review, we focus on the Tat pathway of Gram-positive bacteria. The minimal Tat pathway is composed of two components, namely a TatA and TatC pair, which are often complemented with additional TatA-like ...

Hsp70 proteins in protein translocation

2001
Publisher Summary Hsp70 proteins are essential components of the protein translocation systems of the endoplasmic reticulum (ER) and mitochondria. The role of Hsp70s in protein translocation is not confined to the ER and mitochondria. For most proteins of the ER, translocation is coupled with protein synthesis.

Protein translocation in apoptosis

Trends in Cell Biology, 1999
In programmed cell death (apoptosis), receptor-generated or other signals are transmitted to all cellular compartments, resulting in an apoptotic cell with extensive cytoplasmic and nuclear alterations. Protein translocation is now recognized as being crucial in the induction, amplification and regulation of this process.

Thermodynamics of the Protein Translocation

2009
Many proteins synthesized in bacteria are secreted from the cytoplasm into the periplasm to function in the cell envelope or in the extracellular medium. The Sec translocase is a primary and evolutionary conserved secretion pathway in bacteria. It catalyzes the translocation of unfolded proteins across the cytoplasmic membrane via the pore-forming ...
