Ccr5 inhibition
WebCCR5 antagonists bind to the CCR5 chemokine coreceptor on host cells, induce a conformationalchange that impedes CCR5 interaction with HIV gp120, thereby preventing HIV entry into host cells. Small molecular weight inhibitors of HIV binding to the CD4 molecule are a new approach. Epigallocatechin gallate (EGCG), by blocking gp120 … WebUsing HIV-based lentiviral vectors, we delivered an anti-CCR5 ribozyme (CCR5RZ), a nucleolar localizing TAR RNA decoy, or Pol III-expressed siRNA genes into cultured and primary cells. The CCR5RZ is driven by the adenoviral VA1 Pol III promoter, while the human U6 snRNA Pol III-transcribed TAR decoy is embedded in a U16 snoRNA …
