Most DNA scanning proteins uniquely recognize their cognate sequence motif and slide on DNA assisted by some sort of clamping interface. The pioneer transcription factors that control cell fate in eukaryotes must forgo both elements to gain access to DNA in naked and chromatin forms; thus, whether or how these factors scan naked DNA is unknown. Here, we use single-molecule techniques to investigate naked DNA scanning by the Engrailed homeodomain (enHD) as paradigm of highly promiscuous recognition and open DNA binding interface.

  • - TLR9 agonists, particularly nelitolimod, enhance the immune response against liver tumors by promoting the killing of micro-organisms and cancer cells, although their effectiveness is limited by specific immune cell behaviors and drug delivery challenges.
  • - A new delivery method called pressure-enabled drug delivery (PEDD) improves the targeting of TLR9 agonists to tumors, leading to increased depletion of suppressive immune cells (MDSCs) and overall immune stimulation, especially when combined with checkpoint inhibitors.
  • - In experiments with mice, the system showed promising results when nelitolimod was given directly to the tumor alongside either systemic or subcutaneous administration of immune checkpoint inhibitors, resulting in notable changes in immune cell populations within the tumors.

The effects of two ionic liquids (ILs), 1-butyl-3-methylimidazolium tetrafluoroborate ([bmim]BF) and 1-butyl-1-methyl pyrrolidinium tetrafluoroborate ([bmp]BF), on a mixture of phospholipids (PLs) 1,2-dipalmitoyl--glycero-3-phosphatidylcholine (DPPC), 1,2-dipalmitoyl--glycero-3-phosphoethanolamine (DPPE), and 1,2-dipalmitoyl--glycero-3-phosphoglycerol (DPPG) (6:3:1, M/M/M, 70% PL) in combination with 30 mol % cholesterol (CHOL) were investigated in the form of a solvent-spread monolayer and bilayer (vesicle). Surface pressure (π)-area () isotherm studies, using a Langmuir surface balance, revealed the formation of an expanded monolayer, while the cationic moiety of the IL molecules could electrostatically and hydrophobically bind to the PLs on the palisade layer. Turbidity, dynamic light scattering (size, ζ-potential, and polydispersity index), electron microscopy, small-angle X-ray/neutron scattering, fluorescence spectroscopy, and differential scanning calorimetric studies were carried out to evaluate the effects of IL on the structural organization of bilayer in the vesicles.

While peptide-based drug development is extensively explored, this strategy has limitations due to rapid excretion from the body (or shorter half-life in the body) and vulnerability to protease-mediated degradation. To overcome these limitations, a novel strategy for the development of a peptide-based anticancer agent is introduced, utilizing the conformation switch property of a chameleon sequence stretch (PEP1) derived from a mycobacterium secretory protein, MPT63. The selected peptide is then loaded into a new porous organic polymer (PG-DFC-POP) synthesized using phloroglucinol and a cresol derivative via a condensation reaction to deliver the peptide selectively to cancer cells.
