Costimulatory and adhesion receptor-ligand pairs between Dendritic Cells and Cytokine-Induced Killer cells (DC-CIK costimulatory pairs)

The costimulatory and adhesion receptor-ligand pairs between Dendritic Cells (DCs) and Cytokine-Induced Killer (CIK) cells represent a critical immunological interface used in adoptive immunotherapy (Wang et al., 2014, DOI: 10.1186/s12967-014-0339-9). CIK cells are a heterogeneous population of effector cells, primarily CD3+CD56+ T cells, that possess potent, non-MHC-restricted cytotoxic activity against tumor cells (Schmeel et al., 2015, DOI: 10.1186/s13045-015-0212-8). When co-cultured with DCs, CIK cells exhibit significantly enhanced proliferation, survival, and cytotoxicity due to the engagement of specific surface molecules (Zhang et al., 2012, DOI: 10.1007/s00262-012-1260-3). Key costimulatory interactions include the binding of CD80 and CD86 on DCs to CD28 on CIK cells, as well as the CD40-CD40L (CD154) axis, which triggers the release of pro-inflammatory cytokines like IFN-gamma and IL-12 (Wang et al., 2014). Adhesion molecules, most notably ICAM-1 (CD54) on DCs and LFA-1 (CD11a/CD18) on CIK cells, are essential for forming a stable immunological synapse, allowing for prolonged signaling (Schmeel et al., 2015). This synergistic interaction is the basis for DC-CIK cell therapy, which has been investigated for treating various cancers, including lung, liver, and renal cell carcinomas (Zhang et al., 2012).
