Ans) Inhibitors against neuraminidase have the potential as anti-influenza agents.So, option 2 is correct.
EXPLANATION:
Neuraminidase is present in the spikes, on the surface of Influenza Virus. Around 20% of the spikes present on the surface of Influenza Virus contain Neuraminidase. This enzyme plays an important role in the release of virus particles from the host cells,i.e, involved in the infection process of the Virus.
So, most anti-influenza agents have Neuraminidase as target and eventually block the replication cycle of the virus by interfering with the Budding ( release of the virus from the host cell) of the virus.
Inhibitors against this viral enzyme have potential as anti-influenza agents phosphatidylcholine. neuramidase. hemagglutinin. None of theabove...
immunology practing samples and not sure if my answers correct. 1. NK cells are effective against viral infections because many virus infected cells a. are susceptible to lysis b. are susceptible to phagocytosis c. show reduced levels of MHC class I molecules d. show reduced levels of MHC class II molecules e. none of the above 2. Arachidonic acid serves as a substrate in the lipoxygenase and cyclooxygenase pathways resulting in the production of a. histamine, leukotrienes b. leukotrienes, prostaglandins...
