Peer review of the pesticide risk assessment of the active substance lysate of C2c Maky.

The conclusions of the European Food Safety Authority (EFSA) following the peer review of the initial risk assessments carried out by the competent authority of the rapporteur Member State Austria for the pesticide active substance lysate of C2c Maky and the considerations as regards the inclusion of the substance in Annex IV of Regulation (EC) No 396/2005 are reported. The context of the peer review was that required by Regulation (EC) No 1107/2009 of the European Parliament and of the Council. The conclusions were reached on the basis of the evaluation of the representative use of lysate of C2c Maky as a fungicide against downy mildew () on grapevines and table grapes.

Peer review of the pesticide risk assessment of the active substance phosphine.

The conclusions of the European Food Safety Authority (EFSA) following the peer review of the initial risk assessments carried out by the competent authorities of the rapporteur Member State Spain and co-rapporteur Member State Germany for the pesticide active substance phosphine are reported. The context of the peer review was that required by Commission Implementing Regulation (EU) No 844/2012. The conclusions were reached on the basis of the evaluation of the representative uses of phosphine as a post-harvest indoor insecticide to control insects infesting stored grains (barley, oat, rye, wheat), cacao and coffee beans, tree nuts and oilseeds and dried fruit via gassing application (gas-tight rooms/container).

Anti-PD-1 amplifies costimulation in melanoma-infiltrating T1-like Foxp3 regulatory T cells to alleviate local immunosuppression.

Background: Immune checkpoint inhibitors targeting programmed cell death protein-1 (PD-1) are the first line of treatment for many solid tumors including melanoma. PD-1 blockade enhances the effector functions of melanoma-infiltrating CD8 T cells, leading to durable tumor remissions. However, 55% of patients with melanoma do not respond to treatment.

The IL-2 SYNTHORIN molecule promotes functionally adapted Tregs in a preclinical model of type 1 diabetes.

Deficits in IL-2 signaling can precipitate autoimmunity by altering the function and survival of FoxP3+ regulatory T cells (Tregs) while high concentrations of IL-2 fuel inflammatory responses. Recently, we showed that the non-beta IL-2 SYNTHORIN molecule SAR444336 (SAR'336) can bypass the induction of autoimmune and inflammatory responses by increasing its reliance on IL-2 receptor α chain subunit (CD25) to provide a bona fide IL-2 signal selectively to Tregs, making it an attractive approach for the control of autoimmunity. In this report, we further demonstrate that SAR'336 can support non-beta IL-2 signaling in murine Tregs and limit NK and CD8+ T cells' proliferation and function.
