The uptake of antigen-rich apoptotic bodies by DC coupled with the subsequent release of inflammatory mediators and cellular maturation appears to drive adaptive immunity leading to auto-immunity.
We propose that coat subunit strain release acts in synergy with the first crosslinks to drive forward maturation.
To drive affinity maturation, (GC) B cells undergo rounds of hypermutation and rapid proliferation, which can enhance susceptibility to malignant transformation.
Once primed, robust IFN responses can be unmasked by agonists of the innate adaptor protein, MyD88, through a process that requires cGAS, STING, IRF3, and nuclear factor κB. Thus, HIV-1 replication increases material available for sensing, and discrete inflammatory inputs tune cGAS signaling to drive DC maturation.
Although activated NK cells produce IFN-γ and TNF-α, cytokines able to drive DC maturation process, the NK cell cytotoxicity against autologous iDCs prevails in the presence of a larger number of NK cells compared to that aberrant mature or immature DCs.
Strategies are needed to interrupt this cycle and to drive the maturation of immature DCs towards tolerogenic DCs that induce Tregs.
Several of these genes appear to drive gonad maturation, as they are expressed by follicle cells surrounding both testis and oocyte precursors.
Furthermore, IFNα is described to drive DC maturation required for generation of tumor-specific effector- and central-memory CD8+ T cells [ 7, 8].
Plasmacytoid DCs also upregulate ICOS ligand upon maturation, which has been shown to drive differentiation of T cells into Tr1 cells[ 29].
These data show insult-related proliferation of endogenous spinal neuroprogenitors over a relatively brief time course, and delineate a narrow temporal window for future experimental attempts to drive neuronal maturation and for identifying the factors regulating this process.
