HCMV antiviral drug resistance can be detected by phenotypic or by genotypic drug resistance testing. Phenotypic resistance testing involves cultivation of the virus in cell culture and testing its susceptibility using different antiviral drug concentrations in order to determine EC50 values.
Cytomegalovirus (CMV) (from cyto-'cell' via Greek κύτος kútos - 'container' + μέγας mégas 'big, megalo-' + -virus via Latin vīrus 'poison') is a genus of viruses in the order Herpesvirales, in the family Herpesviridae, [3] in the subfamily Betaherpesvirinae.
English: Mechanisms of anti-HCMV compounds. Ganciclovir (GCV) is monophosphorylated by the HCMV protein kinase pUL97. Cidofovir (CDV) does not require initial phosphorylation for its antiviral action. Further phosphorylation to the triphosphate form of GCV and CDV is performed by cellular kinases.
In the past nucleic acid tests have mainly been used as a secondary test to confirm positive serological results. [3] However, as they become cheaper and more automated, they are increasingly becoming the primary tool for diagnostics and can also be use for monitoring of treatment of viral infected individuals t.
Certain viruses, such as human cytomegalovirus (HCMV) and hepatitis C (HCV), have adapted to suppress the function of MAVS in the antiviral innate immune response, aiding in viral replication. [ 7 ] [ 11 ] HCMV impairs MAVS through the viral mitochondria-localized inhibitor of apoptosis protein (vMIA), thus reducing the pro-inflammatory ...
During maturation of HHV-6 virions, human cell membranes are used to form viral lipid envelopes (as is characteristic of all enveloped viruses). During this process HHV-6 utilizes lipid rafts , which are membranous microdomains enriched by cholesterol , sphingolipids , and glycosylphosphatidylinositol -anchored proteins. [ 25 ]
Valganciclovir, sold under the brand name Valcyte among others, is an antiviral medication used to treat cytomegalovirus (CMV) infection in those with HIV/AIDS or following organ transplant. [3] It is often used long term as it only suppresses rather than cures the infection. [3] Valganciclovir is taken by mouth. [3]
Maribavir, sold under the brand name Livtencity, is an antiviral medication that is used to treat post-transplant cytomegalovirus (CMV). [8] [9] Maribavir is a cytomegalovirus pUL97 kinase inhibitor that works by preventing the activity of human cytomegalovirus enzyme pUL97, thus blocking virus replication.
