Publication date: Available online 14 November 2019Source: Seminars in Cancer BiologyAuthor(s): Radhakrishnan Vishnubalaji, Shaath Hibah, Ramesh Elango, Nehad M. AlajezAbstractSubstantial evolution in cancer therapy has been witnessed lately, steering mainly towards immunotherapeutic approaches, replacing or in combination with classical therapies. Whereas the use of various immunotherapy approaches, such as adoptive T cell therapy, genetically-modified T cells, or immune checkpoint inhibitors, has been a triumph for cancer immunotherapy, the great challenge is the ability of the immune system to sustain long lasting anti-...

Publication date: Available online 14 November 2019Source: Nano TodayAuthor(s): Xiaochen Liu, Dangge Wang, Pengcheng Zhang, Yaping LiAbstractCheckpoint blockade immunotherapy revolutionizes the field of cancer therapy, among which anti-programmed cell death (anti-PD) therapy is the most successful one in clinic. Despite the tremendous advancement, anti-PD therapy is still limited by barriers such as low response rate and immune related adverse effects (AEs), which are mainly resulted from poor intratumoral infiltration of cytotoxic T lymphocytes and off-tumor distribution of the anti-PD drugs. To address these issues, nano...

Antitumor immunity has emerged as a favorable byproduct of radiation therapy (RT), whereby tumor-associated antigens released from irradiated cells unleash innate and adaptive attacks on tumors located both within and outside the radiation field. RT-induced immune responses further provide actionable targets for overcoming tumor resistance to RT (R-RT); immunotherapy (IT) with checkpoint inhibitors or Toll-like receptor (TLR) agonists can markedly improve, if not synergize with, RT in preclinical models, and several of these drugs are currently investigated as radiosensitizers in patients. In an unbiased chemical-genetic s...

AbstractImmune checkpoint blockers (ICB) have revolutionized cancer therapy. However, complete response is observed in a minority of patients and most patients develop immune-related adverse events (irAEs). These include colitis, which can be treated with anti-tumor necrosis factor (TNF) antibodies such as Infliximab. In a recent issue of the Journal for ImmunoTherapy of Cancer, Badran et al. reported that co-administering Infliximab together with ICB to five cancer patients prevents colitis recurrence, with four of them exhibiting overall disease stability. The basis for this treatment strategy stemmed from our pre-clinic...

ConclusionsThe epigenetic modificator EZH2 can suppress the expression of immune checkpoint inhibitor PD-L1 by directly upregulating the promoter H3K27me3 levels ofCD274 andIRF1 in hepatoma cells, and might serve as a potential therapeutic target for combination of immunotherapy for immune-activated HCC.
