Pathogenic cell

The term "Pathogenic cells" refers to a broad category of biological entities that cause disease, including exogenous infectious agents like bacteria, fungi, and parasites, as well as endogenous host cells that have become harmful, such as cancer cells or autoreactive immune cells [1][2]. Because it describes an entire cell rather than a specific molecule, it is not considered a single therapeutic target in the traditional sense; instead, these cells contain numerous specific receptors, enzymes, and structural proteins that serve as targets for drug development [3]. In infectious diseases, pathogenic cells invade host tissues and utilize various virulence factors to bypass immune defenses and replicate [2][4]. In oncology, these cells are characterized by genomic instability and uncontrolled proliferation, often requiring targeted therapies like monoclonal antibodies or small molecule inhibitors to achieve selective elimination [1][5]. Effective treatment strategies focus on identifying unique biochemical or structural differences between the pathogenic cell and healthy host cells to minimize collateral damage [3][4].

Drugs typically target specific molecular components within pathogenic cells, such as inhibiting cell wall synthesis, disrupting DNA replication, blocking protein synthesis, or inducing programmed cell death (apoptosis).
