In the litic cycle, the virus uses the cell's functions to replicate its genetic information and create more viruses.

3.1 Introduction

We are now ready to describe in detail the major intracellular signalling pathways responsible for relaying the signal from the surface receptor to evoke a cellular response. This section will deal with signalling molecules that operate at the cytosolic leaflet of the plasma membrane (trimeric G proteins, monomeric G proteins and lipid-modifying enzymes), second messengers (such as Ca2+, cAMP, cGMP), protein kinases and phosphatases, and finally transcription factors.
