HSV-1 and HSV-2 replication is reduced in rhesus macaque fibroblasts:
The aim behind this experiment was to check whether rhesus monkey cells are more effective against the HSV-1 and HSV-2 replication than Human TRIM5. Rhesus Macaque fibroblast cell lines and HeLa cell lines were infected with HSV-1 KOS and HSV-2 186 syn+ strains at MOI=3 PFU/cell and harvested at different time points post infection. The viral load at these time points are shown the Figure 1.
From the figure we understand that the viral yield from the rhesus monkey cells is almost 100 fold less than the viral yield obtained from the HeLa cells proving that the viral replication is inhibited in the rhesus monkeys. Hence, rhesus monkey fibroblasts were less permissive to HSV infection than HeLa Cells. These results made the scientist ponder whether rhesus monkey TRIM5 has a role to play in the viral yield inhibition.

The effect of the different species TRIM5α was tested on the HeLa cells expressing rhesus monkey (H-R), human (H-H), African green monkey (H-AGM) and squirrel monkey (H-Sq) TRIM5α protein along with H-L cell line having empty vector. The cells were infected HSV-2 186 syn+ strain at an MOI of 3 PFU/cell and harvested after 24h.
Rhesus monkey TRIM5α was shown to inhibit HSV replication by 4.5 folds as compared to H-L cells while 3.6 folds in African green monkey. There was no significant decrease in viral yield in the cells expressing human and squirrel TRIM5α concluding that old world monkeys (OWN) TRIM5α is more effective in inhibiting HSV replication. This also suggest that TRIM5α effect is species specific that means the protein produced by only certain species i.e Old World Monkeys is effective against HSV replication (Figure 3).

    This study focuses on HSV presenting in the skin, eyes, or mouth which is less severe. However, HSV of the skin, eyes, or mouth can progress to more severe diseases such as disseminated HSV or HSV of the central nervous system. Mortality rates of untreated disseminated HSV is 85% and mortality rates of untreated HSV of the central nervous system is 50%. Because the severe cases of HSV are so dangerous, it is imperative that treatment of HSV of the skin, eyes, and mouth prevents progression of the disease. If long-term treatment with Acyclovir is found to successfully suppress HSV of the skin, eyes, and mouth in infants, then further studies can be done to see its efficacy with the more severe diseases.…

    Human bone marrow has been identified as an abundant source of AAV, leading to hypotheses that AAV isolates are present in human CD34+ HSCs (Hematopoietic Stem Cells). Assuming AAV presence in HSCs, AAV capsids might have tropism for CD34+ cells. Natural AAV variants have now been found in CD34+ human peripheral blood stem cells. CD34+ derived AAV variants possess novel viral capsids unlike other AAV serotypes. AAVHSC vectors transduced long term in…

    Ki: 6 nM Narlaprevir is a HCV NS3 protease inhibitor. NS3 protease is essential for viral replication representing an important target for antiviral therapy. Since identification of NS3 protease, this chymotrypsin-like serine protease has been found to be an attractive target for HCV antiviral therapeutics. In vitro: Narlaprevir was identified to be a novel ketoamide protease inhibitor which formed a reversible covalent bond with the active-site serine.…

    HeLa cells are a unique strain of cancerous cells obtained from the cancerous cervical tissue of Henrietta Lacks, who perished to the disease on October 4, 1951. HeLa cells are unique because they are “immortal”. HeLa cells are immortal because they do not experience programmed cell death like normal cells would, allowing the HeLa cells to replicate infinitely without experiencing degeneration of genetic material. It is suspected that Henrietta's human papilloma virus and syphilis played a part in suppressing programmed cell death in HeLa cells. Because of their hardy durability and swift rate of reproduction, HeLa cells have been used in extensive scientific research.…

    The innate responses induce many proinflammatory factors which serve as an antiviral immune such as tumor necrosis factor alpha, interferon gamma (3). Latent Infection of Epstein-Barr virus induces secretion of several inflammatory factors, meanwhile lytic infections avoid the antiviral inflammatory response. Furthermore, it has been proposed that lytic proteins of herpesviruses a key role in avoiding host immune responses, including disruption of interferon signaling. For example, cytomegalovirus, EBV, and Varicella-Zoster virus inhibit IFN-γ-induced MHC class II expression. In addition, Kaposi's sarcoma-associated herpesvirus avoid the immune responses by encoding proteins which interfere with interferon signal transduction and subsequent gene transactivation…

    Introduction When observing a human population there are many phenotypical differences such as; behavior, development, and morphology. Not only are there phenotypical differences amongst a human population, but there are also genotypic differences that can be observed using DNA sequencing data. One way to observe genetic variation amongst humans would be to sequence the Mitochondrial DNA(mtDNA). Mitochondrial DNA is the most commonly used DNA to form phylogenetic trees. Human Mitochondrial DNA is about 16,500 bps in size and consists of 13 protein coding genes, 22 tRNAs (transfer RNA), and 2 rRNAs (ribosomal RNA) (Ingman, 2001).…

    Specifics of this process in FPV continue to be studied, but there is evidence outlining a replication mechanism. Certain proteins are autonomously replicated, but FPV relies on the host cell’s central dogma machinery for most of its metabolism and structural protein synthesis (22). In their study, Lenghaus, Mun, and Studdert found that replication of the virus can still proceed even when cellular processes have been halted (15). These results suggest that FPV does not require the host cell’s full central dogma machinery to carry out its replication. An important sequence of FPV is a hairpin structure found at the 3’ end of viral DNA.…
