Gazdasejtek, or host cells, are the cells that pathogens exploit to reproduce and complete their life cycles. In virology, a host cell is any cell that a virus infects and uses to replicate, assemble viral components, and release new virions. Host cells can be prokaryotic or eukaryotic, with bacteriophages infecting bacterial cells and animal, plant, or fungal viruses infecting their respective hosts.
Entry and replication depend on host factors. The virus must attach to specific receptors on the cell
Host range and tissue tropism determine which cells can be used by a particular pathogen. This depends
Applications and examples: bacteriophages use bacterial host cells; influenza and coronaviruses target respiratory epithelial cells in
Host cells also mount defenses such as innate immune responses and programmed cell death. Viruses counter these
