Myeloid-derived suppressor cells in laryngeal squamous cell carcinoma: an underexplored immunosuppressive axis and strategic target for overcoming checkpoint inhibitor resistance
Laryngeal squamous cell carcinoma (LSCC) shows a persistently low objective response rate to immune checkpoint inhibitors (ICIs) targeting the programmed death-1 (PD-1) pathway. Its immunosuppressive tumor microenvironment (TME), enriched in tumor-asso…
