Cold pathogen

The term "Cold pathogen" does not refer to a specific molecular target or receptor but is a collective term used to describe the diverse group of infectious agents responsible for the common cold and related upper respiratory tract infections. In clinical and traditional medicine contexts, it often refers to environmental stressors or pathogenic influences, such as the "Han Xie" described in Traditional Chinese Medicine. Biologically, this category encompasses over 200 viral strains, most prominently Human Rhinoviruses (HRVs), Coronaviruses, and Respiratory Syncytial Virus (RSV). These pathogens initiate infection by binding to host cell receptors like ICAM-1, LDLR, or CDHR3 and hijacking cellular processes for replication and capsid assembly. Modern therapeutic research focuses on specific molecular targets within this category, such as the viral 3C protease or host enzymes like N-myristoyltransferase (NMT) which are essential for viral proliferation. Because of the vast genomic diversity and rapid evolution of these viruses, no single therapeutic agent currently exists that targets all "cold pathogens" as a unified entity.

Drugs associated with this category typically function by inhibiting specific viral enzymes (e.g., protease inhibitors like Rupintrivir), blocking viral capsid attachment (e.g., Pleconaril), or inhibiting host enzymes required for viral assembly (e.g., NMT inhibitors like IMP-1088).
