The Role of Chemokines in Cervical Cancers

Fabian Garrido et al. Medicina (Kaunas). .

Abstract

Both clinical-pathological and experimental studies have shown that chemokines play a key role in activating the immune checkpoint modulator in cervical cancer progression and are associated with prognosis in tumor cell proliferation, invasion, angiogenesis, chemoresistance, and immunosuppression. Therefore, a clear understanding of chemokines and immune checkpoint modulators is essential for the treatment of this disease. This review discusses the origins and categories of chemokines and the mechanisms that are responsible for activating immune checkpoints in cervical dysplasia and cancer, chemokines as biomarkers, and therapy development that targets immune checkpoints in cervical cancer research.

Keywords: CCL1-28; CX3CL1; CXCL1-17; PD-1; PD-L1; XCL1-2; immune checkpoints.

Summary of the described chemokines of the CC chemokine proteins (or β chemokine proteins) family. These chemokines have two adjacent cysteine (amino acids) near their amino terminus. Although at least 27 different member of this subgroup have been reported for mammals, referred to as CC chemokine ligands (CCL)-1 to -28, we focused in this review on 10 CCL chemokines and described ligand receptor interaction for CCL2, -3, -4, -5, -8, -20 and -22 specifically for their function in cervical cancer. Abbreviations: HPV—human papilloma virus; CCL—C-C Motif Chemokine Ligand; C-C chemokine receptor; E6—HPV E6 protein; E7—HPV E7 protein; OS—overall survival rate; TPCA-1-2-[(aminocarbonyl)amino]-5-(4-fluorophenyl)-3-thiophenecarboxamide; Treg—T regulatory cells.

Summary of the CXC-chemokines, its receptor binding partner and main function in cervical cancer. A total of six CXC-chemokines (CXCL-1, -2, -3, -5, -6, & -8 bind to the same receptor CXCR2. Abbreviations: CX-Ca—carcinoma of the uterine cervix; CXCL—C-X-C motif chemokine; CXCR—C-X-C motif receptor; AKIP1—A-Kinase Interacting Protein 1; OS—overall survival.

Abbreviations: CCR—C-C motif receptor; CCL—C-C motif ligand; CXCL—C-X-C motif ligand; PD-L1 - programmed cell Death protein 1 ligand; E7—HPV E7 protein; IL—interleukin; VEGF—vascular endothelial growth factor; IFN—interferon; T8+—CD8+ T cells; SLC—secondary lymphoid tissue chemokine.
