In cervical squamous cell carcinoma, DCs express immunosuppressive molecules such as indoleamine 2,3-dioxygenase 1 (IDO1) and galectin-9 (LGALS9), while exhibiting low PD-L1 expression, revealing spatially heterogeneous mechanisms of immune suppression [73]. The gene discussed is LGALS9; the disease is cervical squamous cell carcinoma.
