✦ Synopsis

Innate recognition of infection in vertebrates can lead to the induction of adaptive immune responses through activation of dendritic cells (DCs). DCs are activated directly by conserved pathogen molecules and indirectly by inflammatory mediators produced by other cell types that recognise such molecules. In addition, it is likely that DCs are activated by poorly characterised cellular stress molecules and by disturbances in the internal milieu. The multiplicity of innate pathways for DC activation may have evolved to ensure that any signs of infection are detected early, before overwhelming pathogen replication. Understanding which of these signs are both necessary and sufficient to convert DCs into the immunostimulatory antigen-presenting cells that prime appropriate effector T cells may hold the key to improved strategies for vaccination and immunotherapy.

## Abstract Dendritic cells (DC) are the mononuclear cells that initiate adaptive immune responses. Osteoclasts (OC) are the multinucleated giant cells that resorb bone.

## Abstract Fractalkine (FK, also called neurotactin or CX3CL1) is a CX3C chemokine that can chemoattract T lymphocytes, monocytes and NK cells. In our study, we investigated the induction of antitumor response by FK gene transfer. FK gene‐modified 3LL lung carcinoma cells (3LL‐FK) could both secre
