Description
Immunosuppression is needed in HLA identical sibling renal transplantation. We conducted a tolerance trial in this patient cohort using Alemtuzumab induction, donor hematopoietic stem cells, tacrolimus/mycophenolate immunosuppression converted to sirolimus, planning complete drug withdrawal by 24 months post-transplantation. After an additional 12 months with no immunosuppression, normal biopsies and renal function, recipients were considered tolerant. Twenty recipients were enrolled. Of the first 10 (>36 months post-transplantation), 5 had immunosuppression successfully withdrawn for 16-36 months (tolerant), 2 had disease recurrence and 3 had subclinical rejection in protocol biopsies (non-tolerant). Microchimerism disappeared after 1 year, and CD4+CD25highCD127-FOXP3+ T cells and CD19+IgD/M+CD27- B cells increased to 5 years post-transplantation in both groups, whereas immune/inflammatory gene expression pathways in the peripheral blood and urine were differentially downregulated in tolerant compared to non-tolerant recipients. Therefore, in this HLA identical renal transplant tolerance trial, absent chimerism, Treg and Breg immunophenotypes were indistinguishable between tolerant and non-tolerant recipients, but global genomic changes indicating immunomodulation were observed only in tolerant recipients.

Description
15-20 cm tall 35S::Myc-GR-bdl plants were dipped headfirst in 15 µM dexamethasone or mock solution and after three hours of incubation second internodes were harvested and snap frozen in liquid nitrogen. Frozen plant material was pulverized with pestle and mortar and RNA was isolated by phenol/chlorophorm extraction as described previously (Mallory & Vaucheret 2010, PlantCell) with the modification of two additional concluding 70% EtOH washes Overall design: RNA from three samples was pooled and analyzed by RNAseq.

Description
Depletion of immunosuppressive tumor-associated macrophages (TAM) or reprogramming towards a pro-inflammatory activation state represent different strategies to therapeutically target this frequent myeloid population. Here we report that inhibition of colony-stimulating factor-1 receptor (CSF-1R) signaling sensitizes TAM to profound reprogramming in the presence of a CD40 agonist prior to their depletion. Despite the short-lived nature of macrophage hyperactivation, combined CSF-1R/CD40 stimulation of macrophages is sufficient to trigger a productive and durable T cell response in various mouse cancer models. The central role of macrophages in regulating T cell-dependent tumor rejections was substantiated by depletion experiments and transcriptomic analysis of ex vivo sorted TAM. Since CD40 expression on human TAM varies between different tumor types, co-expression of human CSF-1R and CD40 in colorectal adenocarcinoma and mesothelioma can serve as criteria to select these tumor types for clinical development Overall design: Female C57BL/6N mice (6-8 weeks in age, obtained from Charles River) were inoculated with 106 MC38 colorectal adenocarcinoma tumor cells subcutaneously. Tumor growth curves were monitored by caliper measurement and once tumor size reached 250 mm3 in average, groups were allocated for antibody treatment. Ten mice/group were treated with 30 mg/kg IgG1 isotype control antibody clone MOPC-21 (BioXCell), 4 mg/kg anti-CD40 rat IgG2a antibody clone FGK45 (BioXCell), 30mg/kg anti-CSF-1R antibody clone 2G2, 4 mg/kg rat IgG2a control clone 2A3 (BioXCell). For depletion experiments 4mg/kg mouse anti-CD4 antibody clone GK1.5 (Biolegend), 4mg/kg anti-NK1.1 antibody clone PK136 (BioXCell) and 4mg/kg anti-CD8a antibody clone 53-6.7 (BioXCell) were administered when tumor size reached 190mm3 in average. Antibodies were given every second day for four times. In between doses two and three of the depleting antibodies, animals were further treated with vehicle control (0,9% sodium saline), MOPC21, FGK45, 2G2 or combination of FGK45 and 2G2. The anti-CSF-1R antibody or respective IgG1 control antibody were administered weekly until tumors regressed completely or animals reached termination criteria, while the anti-CD40 antibody was only administered once at day 11 simultaneously with the anti-CSF-1R antibody. All antibodies were given intraperitoneally. All procedures were performed in accordance with the National Institutes of Health Guidelines for the Care and Use of Laboratory Animals and European Union directives and guidelines.

Description
Tumor necrosis factor-related weak inducer of apoptosis, TWEAK, is a TNF superfamily member that mediates signaling through its receptor fibroblast growth factor inducible-14, Fn14. In tumor cell lines, TWEAK induces proliferation, survival and NF-kappaB signaling and gene expression that promote tumor growth and suppress antitumor immune responses. Anti-TWEAK antibody, RG7212, inhibits tumor growth in vivo with decreases in pathway activation markers and modulation of tumor, blood and spleen immune cell composition. Candidate response prediction markers, including Fn14, have been identified in mouse models. Phase I pharmacodynamic data from patients are consistent with preclinical results. TWEAK:Fn14 signaling is upregulated in human cancer and pathway activation induces tumor proliferation and survival signaling. Blockade with anti-TWEAK mAb, RG7212, inhibits tumor growth in multiple models in mice. TWEAK induces changes that suppress anti-tumor immune responses and RG7212 blocks these effects resulting in changes in tumor immune cell composition and decreases in cytokines that promote immunosuppression. Antitumor efficacy in mice was observed in a range of Fn14 expressing models with pathway activation and expressing either wild-type or mutant p53, BRAF or KRAS suggesting both a patient selection strategy and potential broad clinical applicability. Preclinical mechanism of action hypotheses are supported by Phase I clinical data, with decreases in proliferation markers and increased tumor T cell infiltration.
