Many factors can affect transduction efficiency. Not all viral particles floating in culture medium can eventually transduce (or infect) the cells. Some additives such as polybrene can enhance the t Chapter 13, . Stryer. Short Course. Signal Transduction. Signal from exterior of cell must affect interior of cell. Through the membrane.

Explanation. : A signal transduction pathway is where signal transduction occurs. Signal transduction occurs when an extracellular signaling molecule activates a specific receptor located on the cell surface or inside the cell. Receptor then causes a chain of event with in the cell, causing a cellular response. Signal transduction pathways can be altered. Signal transduction pathways can be blocked by the use of drugs such as antihistamines. Also signal transduction pathways being blocked can act as a preventative against diseases. A more specific impact of drugs altering cellular response is antihistamines. This changing signal transduction is how the antihistamines block transduction by blocking the histamine that is released by the cells immune system. When a foreign antigen binds to the .
