Human Other Cancer Peripheral Blood Mononuclear Cells

Description

Human Other Cancer Peripheral Blood Mononuclear Cells (PBMCs) are isolated from peripheral blood of patients with less common malignancies, primarily consisting lymphocytes (T cells, B cells, NK cells) and monocytes. Morphologically, these PBMCs are round or oval shaped. In cancer, the composition and function of PBMCs are often abnormal. They exhibit cancer-specific immune alterations, including increased exhausted PD-1⁺ T cells, elevated Tregs populations (CD4⁺CD25⁺FoxP3⁺), and tumor-educated myeloid cells. Additionally, the increase of tumor-associated macrophages (TAMs) and regulatory T cells (Tregs) may promote immune escape, while the decreased activity of cytotoxic T cells (CTLs) weakens anti-tumor immunity. These PBMCs are particularly valuable for studying the unique immunobiology of rare cancers, which often present distinct challenges in immunotherapy development due to their low incidence and heterogeneity. These PBMCs enable in-depth cancer proteomics PBMC, support the development of cancer immunotherapy, integrate genomics PBMC cancer analyses, facilitate comprehensive PBMC characterization oncology, reveal insights into PBMC metabolism cancer, and inform emerging cancer research trends.
