Viral Entry and Replication
Viruses responsible for respiratory infections typically enter the body through airborne transmission or direct contact. They often access host cells via specific receptors located on cell membranes. For example, the influenza virus uses sialic acid receptors found on epithelial cells of the respiratory tract. Once the virus attaches, it infiltrates the host cell, releasing its genetic material, either DNA or RNA, which hijacks the cell's machinery to replicate itself.
The replication process consists of several stages:
- Attachment: The virus binds to receptors.
- Penetration: The virus enters the host cell.
- Uncoating: The viral genome is released into the cell.
- Replication: The cell begins producing viral components.
- Assembly: New viral particles are formed.
- Release: Newly formed viruses exit the cell, often destroying it in the process.
Understanding viral entry and replication not only aids in comprehending the infection process but also highlights potential intervention points for antiviral therapies.
Immune Response to Viral Infections
Upon recognizing viral invasion, the host's immune system mounts a defense through both innate and adaptive responses. The innate response is immediate but non-specific, involving various cells such as macrophages and natural killer cells. These cells work to eliminate infected cells and produce cytokines to signal other immune system components.
The adaptive immune response develops more slowly but offers specificity and memory. Key elements include:
- B cells: Produce antibodies that neutralize viruses.
- T cells: Kill infected cells and help coordinate the immune response.
This dual response is crucial for clearing infections but can also lead to complications. A hyperactive immune response may cause tissue damage, contributing to severe conditions like pneumonia or acute respiratory distress syndrome.
