Definition: In this task, you're given a paragraph from the research paper and your task is to generate a suitable title for the research paper based on the given paper. Under 100 words is a good title length.
Input: Viral infections of the central nervous system (CNS) necessitate rapid, yet tightly controlled responses to contain viral spread while limiting tissue damage. All CNS resident cell types are equipped with pattern recognition receptors (PRRs) to respond to viruses. The resulting activation of IFN-α/β, proinflammatory cytokines and chemokines is dependent on the virus replication strategy, tropism and PRR distribution. Although IFN-α/β induced antiviral mediators are essential to restrict initial viral spread, adaptive immunity promoted by chemokines, cytokines and metalloproteinases is equally critical in lowering viral burden. Recognition of viral antigen presented by MHC molecules is critical for T cell retention and function. Non lytic clearance mechanisms mediated by IFN-γ and antibodies prevail in providing protection. Targeted intervention can be achieved by PRR stimulation, chemokine-receptor blockade and immune modulation of T cell function. However, due to the extensive positive and negative feedback signaling cascades linking innate and adaptive immune responses, enhanced anti-viral functions will have to be counterbalanced to avoid pathology.
