CD28 costimulation is essential for human T regulatory expansion and function.
The costimulatory requirements required for peripheral blood T regulatory cells (Tregs) are unclear. Using cell-based artificial APCs we found that CD28 but not ICOS, OX40, 4-1BB, CD27, or CD40 ligand costimulation maintained high levels of Foxp3 expression and in vitro suppressive function. Only CD28 costimulation in the presence of rapamycin consistently generated Tregs that consistently supp...
متن کاملOX40 costimulation prevents allograft acceptance induced by CD40-CD40L blockade.
Disrupting the CD40-CD40L costimulation pathway promotes allograft acceptance in many settings. Herein, we demonstrate that stimulating OX40 overrides cardiac allograft acceptance induced by disrupting CD40-CD40L interactions. This effect of OX40 stimulation was dependent on CD4(+) T cells, which in turn provided help for CD8(+) T cells and B cells. Allograft rejection was associated with donor...
متن کاملQuasars: What Turns Them Off?
While the high-redshift quasar luminosity function closely parallels the hierarchical growth of dark matter halos, at lower redshifts quasars exhibit an anti-hierarchical turn-off, which moves from the most luminous objects to the faintest. We explore the idea that this may arise from self-regulating feedback, caused by quasar outflows. Using a detailed hydrodynamic simulation we calculate the ...
متن کاملCostimulation of CD8 T cell responses by OX40.
The persistence of functional CD8 T cell responses is dependent on checkpoints established during priming. Although naive CD8 cells can proliferate with a short period of stimulation, CD4 help, inflammation, and/or high peptide affinity are necessary for the survival of CTL and for effective priming. Using OX40-deficient CD8 cells specific for a defined Ag, and agonist and antagonist OX40 reage...
متن کاملT cells and blood vessels: costimulation turns up the pressure.
Remarkable advances in our understanding of innate and adaptive immunity have shed light on why inflammation is centrally involved in the pathogenesis of many diseases traditionally not viewed as primarily inflammatory in nature. One key area of progress has been the discovery and study of innate immune receptors, referred to as pattern recognition receptors (PRRs), such as toll-like receptors ...
