Deciphering the secrets of tumor-initiating cells in pancreatic ductal adenocarcinoma microenvironment: mechanisms and therapeutic opportunities

Pancreatic ductal adenocarcinoma (PDAC) is a highly aggressive malignancy characterized by poor prognosis, strong resistance to therapy, and a dense immunosuppressive tumor microenvironment (TME). A small subset of cells known as cancer stem cells (CSC…

Advances in PD-1/PD-L1 pathway inhibitors in the treatment of thyroid cancer: mechanisms and clinical therapeutic perspectives

Cancer of the thyroid is a endocrine cancer. Although most patients achieve favorable outcomes with surgical resection, radioactive iodine (RAI) ablation, and thyroid-stimulating hormone (TSH) suppression therapy, a subset progresses to advanced or ref…

Systemic immune-inflammation index as a versatile biomarker in autoimmune disorders: insights from rheumatoid arthritis, lupus, and spondyloarthritis

Autoimmune diseases, such as systemic lupus erythematosus (SLE), rheumatoid arthritis (RA), systemic vasculitis, spondyloarthritis (SpA), including ankylosing spondylitis (AS) and psoriatic arthritis (PsA), are characterized by chronic immune activatio…

Melatonin as an anti-inflammatory hormone bridging migraine relief and cancer immunity enhancement: a literature review

Melatonin, once relegated to the circadian periphery, has resurfaced as a pleiotropic immunomodulator capable of quelling neurogenic inflammation while invigorating antitumour defence. Migraine—and its disabling, episodic neurovascular pain—shares an “…

Research progress on mechanisms of tumor immune microenvironment and gastrointestinal resistance to immunotherapy: mini review

Gastrointestinal (GI) tumors present a major clinical challenge due to complex immune evasion mechanisms and generally poor responses to immunotherapy. Tumor immune microenvironment (TIME) is a critical determinant of immunotherapy resistance. Immunosu…
