Yes.
Interferons are anti-microbial substances that can reduce viral replication in uninfected cells by stimulating the cells to produce proteins that inhibit viral replication. Interferons play a key role in the body's immune response to viral infections.
A type of microbial pathogen that invades and destroys host cells is a virus. Viruses, such as the influenza virus or HIV, penetrate host cells and hijack their machinery to replicate, ultimately leading to cell death. This destruction can trigger immune responses, contributing to the symptoms of viral infections. Other examples include certain bacteria, like Listeria, which can also invade and lyse host cells.

Viral infected cells are host cells that have been invaded by viruses, which utilize the cellular machinery to replicate and produce new viral particles. Once infected, these cells may exhibit various changes, including altered metabolism, apoptosis (programmed cell death), or even transformation into cancerous cells, depending on the virus involved. The immune response often targets these infected cells to eliminate them, which can lead to symptoms of viral infections.
Bacterial or Viral infections are a couple of ways cells are damaged or killed.
Viral Infections are diagnosed by the presence of the immune systems production of antibodies, viral fighting cells produced specifically for that specific virus.
In viral infections, lymphocytes, particularly T cells and B cells, are typically elevated. These white blood cells play a crucial role in the immune response by recognizing and attacking viral pathogens. Increased levels of lymphocytes are often used as an indicator of a viral infection during blood tests. Additionally, certain types of lymphocytes, such as CD8+ cytotoxic T cells, are specifically active against infected cells.
Interferon is a protein released by cells infected by a virus that triggers neighboring cells to heighten their anti-viral defenses. Interferon helps protect uninfected cells from viral reproduction by activating their immune response, making it harder for the virus to spread. This immune response can include activating natural killer cells to destroy infected cells and inhibiting viral replication within cells.
Viral infections and cancerous cells
None. It's a viral enzyme.
