Strategy and application of manipulating DCs chemotaxis in disease treatment and vaccine design - 28/03/23
Abstract |
As the most versatile antigen-presenting cells (APCs), dendritic cells (DCs) function as the cardinal commanders in orchestrating innate and adaptive immunity for either eliciting protective immune responses against canceration and microbial invasion or maintaining immune homeostasis/tolerance. In fact, in physiological or pathological conditions, the diversified migratory patterns and exquisite chemotaxis of DCs, prominently manipulate their biological activities in both secondary lymphoid organs (SLOs) as well as homeostatic/inflammatory peripheral tissues in vivo. Thus, the inherent mechanisms or regulation strategies to modulate the directional migration of DCs even could be regarded as the crucial cartographers of the immune system. Herein, we systemically reviewed the existing mechanistic understandings and regulation measures of trafficking both endogenous DC subtypes and reinfused DCs vaccines towards either SLOs or inflammatory foci (including neoplastic lesions, infections, acute/chronic tissue inflammations, autoimmune diseases and graft sites). Furthermore, we briefly introduced the DCs-participated prophylactic and therapeutic clinical application against disparate diseases, and also provided insights into the future clinical immunotherapies development as well as the vaccines design associated with modulating DCs mobilization modes.

In brief: Manipulating DCs chemotaxis in vivo could be efficacious in either immune responses amplification or tolerance induction, which may contribute to either prevention and cure against malignancies/infections or amelioration of autoimmune disorders in clinical. The existing regulation strategies to modulate DCs migratory ma0.nners mainly include direct regulation of chemokine receptors, regulation of chemokine concentration in destinations, modulating monocyte precursors infiltration and DCs differentiation, and physical method-manipulated DCs locomotion.

Highlights |
• | Diversified migratory modes and exquisite chemotaxis behavior of DCs modulate their multifunctional biological activities. |
• | Spatiotemporal positioning of DCs in either SLOs or inflammatory foci endows DCs with appropriate immunological competence. |
• | Regulating chemokines and their receptors expression, altering pre-DCs trafficking, and physical measure are main strategies. |
• | Modulating DCs trafficking in clinic may be conductive to augment anti-tumor therapy effect and optimize vaccine design. |
