Many thought a new age was coming, in which the chaotic spread of cancer would be hindered by drugs that would be precision-targeted to block the replication of rogue cells.
Furthermore, T cell-mediated opening of the BBB and the BNB is crucial to allow antibody access and thereby block the replication of neurotropic viruses.
The objectives of the studies reported here were to design miRNAs that can block the replication of herpes simplex virus 1 and which could be delivered to infected cells via exosomes.
Our model-based approach enables the characterization of the four phases of the cell cycle G1, S, G2, and M, which enables the study of the effect of inhibitor compounds that are designed to block the replication of cancerous cells in any of the phases.
The CC chemokines RANTES, MIP-1α and MIP-1β, the natural ligands for the CCR5 chemokine receptor, and SDF-1α, the natural ligand for the CXCR4 coreceptor, have been shown to successfully block the replication of HIV-1 in vitro [13], [14].
However, the mechanistic basis for this activity is not well understood, the importance of the PI3K/Akt pathway in viral replication is controversial, and AKTIV has been reported to block the replication of negative-strand RNA viruses through a Akt-independent mechanism.
Overall, these findings suggested that curcumin may directly block the replication machinery of viruses or regulate cellular metabolic or signaling pathways which are exploited by viruses.
Antiretroviral medications, such as HAART, inhibit or block the replication part of the HIV-1 life cycle, but the virus cannot be completely eliminated (Guihot et al., 2011; Volberding and Deeks, 2010).
This RNAi system was found to effectively block the replication and gene expression of these viruses in rhabdomyosarcoma (RD) cells and virus-infected mice model.
