WebMar 2, 2024 · Abstract. Macrophages (MΦ) play a critical role in tumor growth, immunosuppression, and inhibition of adaptive immune responses in cancer. Hence, targeting signaling pathways in MΦs that promote tumor immunosuppression will provide therapeutic benefit. PI3Kγ has been recently established by our group and others as a … WebApr 23, 2024 · To efficiently deliver CpG oligodeoxynucleotides (ODNs) to macrophages for the reversal of cancer-induced immunosuppression, …

WebSep 10, 2024 · The antimicrobial peptide FIKRIARLLRKIF, known as Kn2-7, increased the CpG DNA–dependent secretion of interleukin-10 (IL-10) and tumor necrosis factor-α from mouse macrophage-like RAW264.7 cells. Kn2-7 enhanced the cellular uptake of CpG DNA; this effect was decreased by the substitution of arginine residues with alanine residues, … WebThese M2pep-rHF-CpG nanoparticles repolarized M2 TAMs to the M1 type and inhibited tumor growth in 4T1 tumor-bearing mice after intravenous injection. Furthermore, M2pep-rHF-CpG also reversed the phenotype of cultured human macrophages in vitro. Interestingly, the empty M2pep-rHF nanoparticles lacking CpG ODNs also exhibited anti …
WebApr 10, 2024 · Consistent with previous results, the protective effects of cfDNA scavenging and neutrophils depletion were observed in CpG-induced liver injury mice, while macrophage depletion increased live damage in the same model (Figure 3E–H and Figure S7H, Supporting Information).

WebMar 21, 2024 · Second, CpG acted directly on monocytes in vitro to promote their differentiation into macrophages, whereas LPS did not. Third, CpG exposure was able to strikingly increase IM ability to produce IL-10, which was not the case for LPS. Because CpG and LPS are known to act via distinct TLRs, which are expressed at different levels …
WebThe use of a triethylene glycol (TEG) spacer on top of the traditional poly-thymidine spacer increased CpG macrophage stimulatory effects without sacrificing DNA content on the nanoparticle, which directly correlates to particle uptake.
