Question

What substance, produced by virus-infected cells, diffuses to neighboring cells to help them fight a viral infection

Answer 1

Interferons:  

The body releases glycoproteins as the defensive response to virus are called interferons.

The interferons initiate the series of molecular changes and elicit the immune cells to fight the pathogens or foreign particles. These interferons affect the growth of cells and inflammation. Interferons are the cytokines and are responsible for intercellular signalling. The interferons does not directly affect the multiplication of virus instead, it does not let other cells allow virus to use its machinery and replicate. Interferons are of three types: alpha, beta and gamma. The gamma interferon is majorly responsible for the immune response.
