Which of the Following Is True When Interferon Attaches To a Cell?
Interferon (IFN) is a type of cytokine that is secreted by host cells in response to virus infection. It is part of the body’s first line of defense against viral infections. When interferon attaches to a cell, it can have a variety of effects, depending on the particular type of virus and cell involved. Here is a brief overview of what happens when interferon attaches to a cell.
Antiviral Activity of Interferon
When interferon binds to a cell, it triggers an antiviral response in the cell. This response stimulates the cell to produce proteins that help to inhibit viral replication, as well as proteins that activate other immune responses. In addition, interferon can also induce apoptosis, or programmed cell death, in certain types of cells. This helps to prevent further spread of the virus.
Henipavirus Infection
When a cell is infected with a henipavirus, interferon does not typically induce production. However, it may still activate certain immune responses. Studies have shown that interferon can bind to and activate certain receptors in the cell, which can then trigger a response in the signaling pathways of the cell. These responses may help to inhibit the virus from replicating and spreading.
Effects of Interferon on Animal Cells
In animal cells, interferon can activate certain immune pathways and inhibit viral replication. It can also induce apoptosis in certain types of cells, which can help to stop the spread of the virus. Additionally, interferon can also stimulate the production of certain proteins in the cell, which can help to activate other immune responses.
Conclusion
In summary, when interferon attaches to a cell, it can have a variety of effects, depending on the particular type of virus and cell involved. Interferon can trigger an antiviral response, inhibit viral replication, induce apoptosis, and stimulate the production of other immune responses. As such, it is an important part of the body’s first line of defense against viral infections.
