These cells had enhanced immunosuppression <i>in vitro</i> in terms of inhibiting splenocyte proliferation, reducing proinflammatory factors (IL-1<i>β</i>, TNF-<i>α</i>, IL-17, and IL-6), and suppressing autoantibodies (anti-dsDNA and anti-ANA).
Also, m-Tyr treatment prevents both the reduction of splenic lymphocytes and the increase of the expression of programmed death ligand-1 in splenic myeloid cells associated with immunosuppression.
Use of Mammalian Target of Rapamycin Inhibitors for Pancreas Transplant Immunosuppression Is Associated With Improved Allograft Survival and Improved Early Patient Survival.
We propose that VEGF blockade coupled with glioma-derived glutamate induces systemic and intratumoral immunosuppression by promoting Treg overrepresentation and function, which can be pre-emptively overcome through Treg depletion for enhanced antitumor effects.

Rather than comprehensively reviewing known functions of calcineurin, we highlight new approaches to substrate identification for this critical regulator that may reveal molecular mechanisms underlying toxicities caused by calcineurin inhibitor-based immunosuppression.
This study sought to examine whether conversion from calcineurin inhibitor (CNI)-based to SRL-based IS was associated with decreased risk of malignancy post-HT.
Theoretically, the use of IL-17 monoclonal antibodies to inhibit Th17 pathway may lead to further immunosuppression and disease progression in cutaneous T-cell lymphoma (CTCL) by shifting the balance towards Tregs, although this hypothesis has not been proven.
Here we describe 3 key mechanisms related to vascular endothelial growth factor (VEGF)-mediated immunosuppression: inhibition of dendritic cell maturation, reduction of T-cell tumor infiltration, and promotion of inhibitory cells in the tumor microenvironment; supporting data are also described.
Our results propose a rationale to overcome tumor immunosuppression and the current limitations of VEGF monotherapy by integrating the synergistic effects of VEGF/Ang-2 and PD-1 blockade to reinforce antitumor immunity through a normalized vasculature.
SIGNIFICANCE: These findings show in a model of HER2<sup>+</sup> breast cancer that necrosis secondary to impaired efferocytosis activates IDO1 to drive immunosuppression and tumor progression.
Those changes may impact clinical immunosuppression with evidences suggesting age-specific efficacies of some (CNI and mammalian target of rapamycin inhibitors) but not necessarily all immunosuppressants.
In a murine glioma model, HGGs induced with FGL2 exhibited a mesenchymal phenotype and increased CD4+ forkhead box P3 (FoxP3)+ Treg cells, implicating immunosuppression as a mechanism for tumor progression.
According to short-term in vitro results, it was reconfirmed that the resistance to programmed death-ligand 1 (PD-L1)-mediated immunosuppression could be enhanced by PD-1 blockade.
