BRCA1 -mutated tumors may be particularly vulnerable to dual checkpoint inhibition.
Synthetic CpG oligonucleotides (ODN) have potent immunostimulatory properties exploited in clinical vaccine trials. How ODN are captured and delivered to the intracellular receptor TLR9, however, has been elusive. Here we show that DEC-205, a multilectin expressed by variety of cells, is for ODN. When used as an adjuvant, mice deficient DEC-205 impaired dendritic cell (DC) B-cell maturation, unable make some cytokines such IL-12, display suboptimal cytotoxic T-cell responses. We reveal...
Abstract Venetoclax, a potent and selective BCL2 inhibitor, synergizes with endocrine therapy in preclinical models of ER-positive breast cancer. Using phase Ib 3 + dose-escalation expansion study design, 33 patients ER BCL2-positive metastatic disease (mean prior regimens, 2; range, 0–8) were treated daily tamoxifen (20 mg) venetoclax (200–800 mg). Apart from uncomplicated “on-target” lymphopenia, no dose-limiting toxicities or high-grade adverse events observed the escalation (15...
Abstract Purpose: Although cyclin-dependent kinase 4 and 6 (CDK4/6) inhibitors significantly extend tumor response in patients with metastatic estrogen receptor–positive (ER+) breast cancer, relapse is almost inevitable. This may, part, reflect the failure of CDK4/6 to induce apoptotic cell death. We therefore evaluated combination therapy ABT-199 (venetoclax), a potent selective BCL2 inhibitor. Experimental Design: family member expression was assessed following treatment endocrine...
One of the most robust synthetic lethal interactions observed in multiple functional genomic screens has been dependency on PRMT5 cancer cells with MTAP deletion. We report discovery clinical stage MTA-cooperative inhibitor AMG 193, which preferentially binds presence MTA and potent biochemical cellular activity MTAP-deleted across lineages. In vitro, inhibition induces DNA damage, cell cycle arrest, aberrant alternative mRNA splicing cells. human line patient-derived xenograft models, 193...
Abstract The linear ubiquitin chain assembly complex (LUBAC) is essential for innate immunity in mice and humans, yet its role adaptive unclear. Here we show that the LUBAC components HOIP, HOIL-1 SHARPIN have roles late thymocyte differentiation, FOXP3 + regulatory T (Treg)-cell development Treg cell homeostasis. activity not required to prevent TNF-induced apoptosis or necroptosis but necessary transcriptional programme of penultimate stage differentiation. cell-specific ablation HOIP...
