Viral Pathogenesis

Viral pathogenesis involves the study of how viruses infect host cells, replicate, and cause disease. Viruses have evolved diverse strategies to evade host immune responses, replicate within host cells, and spread to other tissues. Viral pathogenesis can vary depending on the type of virus, its tropism for different cell types, and the host's immune status. The interaction between viral proteins and host cell receptors plays a critical role in viral entry and infection. Some viruses establish lifelong latent infections, while others cause acute, self-limited diseases. Understanding viral pathogenesis is essential for developing antiviral therapies and vaccines.
