Miscellaneousi

Miscellaneous

Phosphorylates and thereby activates certain drugs like acyclovir (ACV), valacyclovir, and famciclovir to a toxic form, that leads to successful suppression of the infection, while the uninfected cell does not have this ability because it lacks TK. Mutations in thymidine kinase may induce HSV resistance to antiviral therapies in immunocompromised patients. The most frequently observed resistant strains are unable to express TK and are avirulent in animal models of disease. Resistance may be acquired less frequently by selecting variants which no longer recognize ACV or ACV triphosphate as substrates but which retain normal functions By similarity.
