【 摘 要 】

The delineation of key molecular pathways has enhanced our knowledge of the biology of tumor microenvironment, tumor dissemination, and carcinogenesis. The complexities of cell-cell communication and the possibilities for modulation provide new opportunities for treating cancers. Cells communicate by direct and indirect signaling. Direct cell-cell communication involves both, self-self-communication (intracrine and autocrine), and adjacent communication with nearby cells (juxtacrine), which themselves are regulated by distinct pathways. Indirect intercellular communication involves local communication over short distances (paracrine and synaptic signaling) or over large distances via hormones (endocrine). The essential components of cell-cell communication involve communication junctions (Connexins, Plasmodesmata, Ion Channels, Chemical Synapses, and Pannexins), occluding junctions (Tight Junctions), and anchoring junctions (Adherens, Desmosomes, Focal Adhesions, and Hemidesmosomes). The communication pathways pass through junctions at physical cell-cell attachments, and they go, as well, through the extracellular matrix (ECM) via the different transmembrane adhesion proteins (Cadherins and Integrins). We have here reviewed cell-cell communication involving (1) the components of junctions and their dynamic interplay with the other aspects of communication, including (2) the tumor microenvironment and carcinogenesis, (3) coupling and migration, (4) the underlying cell-cell and sub-cellular communication mechanisms (signaling) of anticancer treatments, and finally, (5) aspects of recent research on cell-cell communication.
