Removal of homeostatic cytokine sinks by lymphodepletion enhances the efficacy of adoptively transferred tumor-specific CD8+ T cells
Depletion of immune elements before adoptive cell transfer (ACT) can dramatically improve the antitumor efficacy of transferred CD8+ T cells, but the specific mechanisms that contribute to this enhanced immunity remain poorly defined. Elimination of CD4+CD25+ regulatory T (T reg) cells has been proposed as a key mechanism by which lymphodepletion augments ACT-based immunotherapy. We found that ...
متن کاملCytokines in chronic rheumatic diseases: is everything lack of homeostatic balance?
Biological systems have powerful inbuilt mechanisms of control intended to maintain homeostasis. Cytokines are no exception to this rule, and imbalance in cytokine activities may lead to inflammation with subsequent tissue and organ damage, altered function, and death. Balance is achieved through multiple, not mutually exclusive, mechanisms including the simultaneous production of agonist and a...
متن کاملDisordered sleep, nocturnal cytokines, and immunity: interactions between alcohol dependence and African-American ethnicity.
Sleep disturbance is one of the most prominent complaints of alcohol-dependent patients. In view of recent evidence that the immune system is integrated with other homeostatic processes ultimately regulated by the brain, the influence of sleep on host defense mechanisms and the expression of proinflammatory and T helper cell cytokines deserves attention in alcohol dependence. Although not all i...
متن کاملInduction of antitumor immune response by homeostatic proliferation and CD28 signaling.
Inducing lymphopenia before adoptive cell transfer can improve the antitumor effect of donor immune cells. It was recently reported that lymphopenic conditions can initiate the differentiation of naive T cells into effector cells. Although T cells require a specific "strong" signal via TCR as well as costimulatory signals during Ag-driven differentiation, there has been little evidence to sugge...
متن کاملIL-7 is critical for homeostatic proliferation and survival of naive T cells.
In T cell-deficient conditions, naive T cells undergo spontaneous "homeostatic" proliferation in response to contact with self-MHC/peptide ligands. With the aid of an in vitro system, we show here that homeostatic proliferation is also cytokine-dependent. The cytokines IL-4, IL-7, and IL-15 enhanced homeostatic proliferation of naive T cells in vitro. Of these cytokines, only IL-7 was found to ...
متن کاملLung-derived innate cytokines: new epigenetic targets of allergen-specific sublingual immunotherapy
Objective(s):Sublingual allergen-specific immunotherapy is a safe and effective method for treatment of IgE-mediated respiratory allergies; however, the underlying mechanisms are not fully understood. This study was planned to test whether sublingual immunotherapy (SLIT) can exert epigenetic mechanisms through which the airway allergic responses can be extinguished. Materials and Methods:BALB/c...
