HERA-GITRL activates T cells and promotes anti-tumor efficacy independent of FcγR-binding functionality

Journal for ImmunoTherapy of Cancer, 2019
Background Glucocorticoid-induced TNFR-related protein (TNFRSF18, GITR, CD357), expressed by T cells, and its ligand (TNFSF18, GITRL), expressed by myeloid populations, provide co-stimulatory signals that boost T cell activity.

Parton distributions from LHC, HERA, Tevatron and fixed target data: MSHT20 PDFs [PDF]

The European Physical Journal C, 2020
We present the new MSHT20 set of parton distribution functions (PDFs) of the proton, determined from global analyses of the available hard scattering data. The PDFs are made available at NNLO, NLO, and LO, and supersede the MMHT14 sets. They are obtained
