Biology lab report research question: effects of ph on amylase activity introduction: amylase is an enzyme that is in human’s saliva as well as the pancreas. Vaccines and anti-viral drugs for treatment in some cases, vaccines can be used to treat an active viral infection the concept behind this is that by giving the vaccine, immunity is boosted without adding more disease-causing virus. In this study we have investigated the regulation of antiviral signaling by increased mtros production in plasmacytoid dendritic cells (pdcs), which, as major producers of type i interferons (ifn), are the key coordinators of antiviral immunity.
