K Cell Adoptive Immunotherapy of Cancer: Evaluating Recognition Strategies and Overcoming Limitations

A lymphocyte of the innate immune response, Natural Killer (NK) cells are phenotypically defined by the absence of CD3 and the presence of CD56 on their surface.1, 2 Functionally, they resemble CD8+ cytotoxic T cells.3 NK cells derive their name from their ability to spontaneously kill their targets without the need for a prior encounter of the antigen, as they have readily available lytic granules that can activate within minutes,4 unlike their T cell counterparts. NK cell targets include stressed, virally-infected, and transformed cells.

Pancreatic cancer is considered a lethal disease with a low survival rate due to its late-stage diagnosis, few opportunities for resection and lack of effective therapeutic strategies. Multiple, highly complex effects of gut microbiota on pancreatic cancer have been recognized as potential strategies for targeting tumorigenesis, development and treatment in recent decades; some of the treatments include antibiotics, probiotics, and fecal microbiota transplantation. Several bacterial species are associated with carcinogenesis of the pancreas, while some bacterial metabolites contribute to tumor-associated low-grade inflamma...

amouzis Schizas Hepatocellular carcinoma (HCC) is one of one of the most frequent liver cancers and the fourth leading cause of cancer-related mortality worldwide. Current treatment options such as surgery, neoadjuvant chemoradiotherapy, liver transplantation, and radiofrequency ablation will benefit only a very small percentage of patients. Immunotherapy is a novel treatment approach representing an effective and promising option against several types of cancer. The aim of our study is to present the currently ongoing clinical trials and to evaluate the efficacy of immunotherapy in HCC. In this paper, we demonstrat...

Hepatocellular carcinoma is a highly prevalent and lethal cancer that many therapeutics are being tested for this disease. It has the potential to be a highly immune-responsive tumor given its inflammatory origins. The first immunotherapies were anti-programmed death-1 monotherapies, which improved response rates and survival. Novel immunotherapy combinations and immunotherapy show promise in frontline treatment. The novel antibody therapy combination of atezolizumab and bevacizumab may be practice changing. Although these landmark studies seem to offer new treatment options, the role of immunotherapy in the liver transpla...

In this study, we found that an angiogenesis inhibitor apatinib enhanced anti-PD-1 therapy for colon cancer in mice via promoting PD-L1 expression. Apatinib treatment upregulated PD-L1 expression in various colon cancer cells both at the mRNA and protein levels. Further, apatinib-treated cancer cells hampered activation and IFN-γ secretion of T cells in the co-culture system, which was reversed by the anti-PD-1 antibody. Based on this, the combination of apatinib with anti-PD-1 on colon cancer growth in mice was examined. The combination treatment showed more significant inhibition on the growth of transplanted tumor...

Cancers, Vol. 12, Pages 1966: Combined C-Reactive Protein and Novel Inflammatory Parameters as a Predictor in Cancer—What Can We Learn from the Hematological Experience? Cancers doi: 10.3390/cancers12071966 Authors: Øystein Bruserud Helene Hersvik Aarstad Tor Henrik Anderson Tvedt The acute phase reaction is a systemic response to acute or chronic inflammation. The serum level of C-reactive protein (CRP) is the only acute phase biomarker widely used in routine clinical practice, including its uses for prognostics and therapy monitoring in cancer patients. Although Interleukin 6 (IL6) is a main trig...

CONCLUSIONS: The significant roles of cell therapy may include an auto-transplant with high-dose treatment, an improvement of the immune function, the creation of chimeric antigen receptor T cells, and the recruitment of NK cellbased immunotherapy. PMID: 32660407 [PubMed - as supplied by publisher]
