WebOccurrence and detection of the CCR5 tropism are some of the great challenges of maraviroc use in treatment-experienced patients. Although up to 80% of naive patients harbor CCR5-tropic virus, the occurrence of CXCR4 or other tropisms increases with the duration of HIV infection and treatment. Nonetheless, maraviroc is a potent medication … WebThe tissue tropism of arboviruses can be divided into three categories: 1 the CNS (e.g. encephalitis, aseptic meningitis) 2 visceral organs (e.g. hepatitis and haemorrhagic fevers) 3 febrile infections. Human arbovirus infections become clinically manifest according to the target organ principally infected ( Table 51.3 ).
WebIn addition, recent studies indicate that alpha2,3- and alpha2,6-linked sialic acids are not the sole receptors determining tissue and host tropism of influenza viruses. In fact, determinants for tissue and host tropism of human, avian and animal influenza viruses are more complex than what has been generally accepted.
