Rapid Production of Physiologic Dendritic Cells (phDC) for Immunotherapy.

Rapid Production of Physiologic Dendritic Cells (phDC) for Immunotherapy. Methods Mol Biol. 2020;2097:173-195 Authors: Hanlon D, Sobolev O, Han P, Ventura A, Vassall A, Kibbi N, Yurter A, Robinson E, Filler R, Tatsuno K, Edelson RL Abstract Generation of large numbers of dendritic cells (DC) for research or immunotherapeutic purposes typically involves in vitro conversion of murine bone marrow precursors or human blood monocytes to DC via cultivation with supraphysiologic concentrations of cytokines such as GM-CSF and IL-4 for up to 7 days. Alternatively, our group has recently established a new approach, based on the underlying mechanism of action of a widely used cancer immunotherapy termed Extracorporeal Photochemotherapy (ECP). Our method of rapid and cytokine-free production of therapeutically relevant DC populations, leveraging the innate physiologic programs likely responsible for DC differentiation from blood monocytes in vivo, potentially offers a novel, inexpensive, and easily accessible source of DC for clinical and research uses. This approach involves ex vivo physiologic reprogramming of blood monocytes to immunologically tunable dendritic antigen-presenting cells, which we term "phDC," for physiological DC. To facilitate access and utilization of these new DC populations by the research community, in this chapter, we describe the use of a scaled-down version of the clinical ECP leukocyte-treatment dev...

AbstractWhile screening programs and HPV vaccination have decreased the incidence of cervical cancer, still over 13,000 cases occur in the USA annually. Early-stage cervical cancer has an excellent long-term prognosis, with 5-year survival for localized disease being  >  90%. Survival decreases markedly for both locally advanced and metastatic disease, and both are associated with a higher risk of recurrence. Few effective treatment options exist for persistent, recurrent, or metastatic cervical cancer. In 2014, the anti-VEGF antibody bevacizumab was approved in combination with chemotherapy based on the r...

ins I Abstract Allogeneic cancer cell lines serve as universal source of tumor-associated antigens in cancer vaccines. Immunogenic high hydrostatic pressure-killed cancer cells derived from cell lines can be used for the generation of dendritic cell (DC)-based active cellular immunotherapy of non-small cell lung cancer (NSCLC). We investigated the expression of 12 known NSCLC tumor-associated antigens (TAA) (CEA, MAGE-A1, MAGE-A3, MAGE-A4, PRAME, hTERT, HER2, MUC1, Survivin, STEAP1, SOX2 and NY-ESO-1) in 6 NSCLC cell lines as candidates for the generation of DC-based lung cancer vaccine. We showed that the selecte...

Abstract The great success of immunotherapy is paving the way for a new era in cancer treatment and is driving major improvements in the therapy of patients suffering from a range of solid tumors. However, the choice of the appropriate tumor antigens to be targeted with cancer vaccines and T-cell therapies is still a challenge. Most antigens targeted so far have been identified on the tumor bulk and are expressed on differentiated cancer cells. The discovery of a small population of cancer stem cells (CSC), which is refractory to most current therapies and responsible for the development of metastasis and recurren...

AbstractClinical progress in the field of HER2-positive breast cancer therapy has been dramatically improved by understanding of the immune regulatory mechanisms of tumor microenvironment. Passive immunotherapy utilizing recombinant monoclonal antibodies (mAbs), particularly trastuzumab and pertuzumab has proved to be an effective strategy in HER2-positive breast cancer treatment. However, resistance to mAb therapy and relapse of disease are still considered important challenges in clinical practice. There are increasing reports on the induction of cellular and humoral immune responses in HER2-positive breast cancer patien...

AbstractWe have established a platform for the isolation of tumour-specific TCR from T cells of patients who experienced clinical benefit from cancer vaccination. In this review we will present the rationale behind this strategy and discuss the advantages of working with “natural” wild type TCRs. Indeed, the general trend in the field has been to use various modifications to enhance the affinity of such therapeutic TCRs. This was done to obtain stronger T cell responses, often at the cost of safety. We further describe antigen targets and recent in vitro and in vivo results obtained to validate them. We finally...

(Rush University Medical Center) Physicians and scientists at Rush University Medical Center have found that injecting tumors with influenza vaccines, including some FDA-approved seasonal flu shots, turns cold tumors to hot, a discovery that could lead to an immunotherapy to treat cancer. The study results were published December 30th in the Proceedings of the National Academy of Sciences.

Efficacy of dendritic cell (DC) cancer vaccines is classically thought to depend on their antigen-presenting cell (APC) activity. Studies show, however, that DC vaccine priming of cytotoxic T lymphocytes (CTLs) requires the activity of endogenous DCs, suggesting that exogenous DCs stimulate antitumor immunity by transferring antigens (Ags) to endogenous DCs. Such Ag transfer functions are most commonly ascribed to monocytes, implying that undifferentiated monocytes would function equally well as a vaccine modality and need not be differentiated to DCs to be effective. Here, we used several murine cancer models to test the ...
