  • It is concluded that antimicrobial peptides such as melittin and cecropin are capable of inhibiting cell-associated production of HIV-1 by suppressing HIV-1 gene expression. (microbiologyresearch.org)
  • This results in inhibition of NFκB activity and the NFκB-dependent expression of anti-apoptotic genes of the Bcl-2 family [ 15 ]. (biomedcentral.com)
  • We showed previously that cytoplasmic release of mtDNA activates the cGAS STING TBK1 pathway resulting in interferon-stimulated gene (ISG) expression that promotes antiviral immunity4. (regenerativemedicine.net)
  • Here, we find that persistent mtDNA stress is not associated with basally activated NF-κB signalling or interferon gene expression typical of an acute antiviral response. (regenerativemedicine.net)
  • Vaccination of mice using the West Nile virus E-protein in a DNA prime-protein boost strategy stimulates cell-mediated immunity and protects mice against a lethal challenge. (rightinstitute.net)
  • Additionally, the hexon component of AdV capsid can bind to coagulation factor X (FX) to activate TLR4 on the surface of splenic macrophages and thereby stimulate NF-κB dependent activation of IL-1β, which may help recruit polymorphonuclear leukocytes to the marginal zone of the spleen and clear virus from the spleen rapidly [49, 50].
