New Cell Sources for T Cell Engineering and Adoptive Immunotherapy

New Cell Sources for T Cell Engineering and Adoptive Immunotherapy | Immunology and Biotherapies | Scoop.it

The promising clinical results obtained with engineered T cells, including chimeric antigen receptor (CAR) therapy, call for further advancements to facilitate and broaden their applicability. One potentially beneficial innovation is to exploit new T cell sources that reduce the need for autologous cell manufacturing and enable cell transfer across histocompatibility barriers. Here we review emerging T cell engineering approaches that utilize alternative T cell sources, which include virus-specific or T cell receptor-less allogeneic T cells, expanded lymphoid progenitors, and induced pluripotent stem cell (iPSC)-derived T lymphocytes. The latter offer the prospect for true off-the-shelf, genetically enhanced, histocompatible cell therapy products.

Cancer Gene Therapy - Towards a commercial process for the manufacture of genetically modified T cells for therapy

Cancer Gene Therapy - Towards a commercial process for the manufacture of genetically modified T cells for therapy | Immunology and Biotherapies | Scoop.it

Abstract

The recent successes of adoptive T-cell immunotherapy for the treatment of hematologic malignancies have highlighted the need for manufacturing processes that are robust and scalable for product commercialization. Here we review some of the more outstanding issues surrounding commercial scale manufacturing of personalized-adoptive T-cell medicinal products. These include closed system operations, improving process robustness and simplifying work flows, reducing labor intensity by implementing process automation, scalability and cost, as well as appropriate testing and tracking of products, all while maintaining strict adherence to Current Good Manufacturing Practices and regulatory guidelines. A decentralized manufacturing model is proposed, where in the future patients’ cells could be processed at the point-of-care in the hospital.

Gilbert C FAURE's insight:

UPENN’s approach (as well as Juno’s) involves Chimeric Antigen Receptors (CAR T-cell), comprised of consists of an intracellular T-cell receptor CD3-zeta chain signaling domain that induces T-cell activation, a costimulatory 4-1BB domain that enhances T-cell mediated responses and anti-CD19 antibody fragments that bind to CD19. So, the main difference between Adaptimmune’s approach and UPENN’s is that Adaptimmune uses the T Cell Receptor, itself, and UPENN creates a T Cell Receptor-like molecule using an antibody targeting domain for CD19, which is on the surface of B cells. In clinical studies, 90% patients with acute lymphoblastic leukemia achieved a complete response.

Immune-mediated mechanisms influencing the efficacy of anticancer therapies: Trends in Immunology

Immune-mediated mechanisms influencing the efficacy of anticancer therapies: Trends in Immunology | Immunology and Biotherapies | Scoop.it

Highlights

 

•Anticancer therapies alter the composition, phenotype, and function of immune cells.•The immune system is a major regulator of the success of anticancer therapy.•Immunotherapy and immunomodulatory agents often synergize with conventional therapies.•Resistance mechanisms following immunotherapy and immunodulatory agents are not fully defined.•Targeting both cancer cells and immune cells may be the key to fight metastasis.

 

Conventional anticancer therapies, such as chemotherapy, radiotherapy, and targeted therapy, are designed to kill cancer cells. However, the efficacy of anticancer therapies is not only determined by their direct effects on cancer cells but also by off-target effects within the host immune system. Cytotoxic treatment regimens elicit several changes in immune-related parameters including the composition, phenotype, and function of immune cells. Here we discuss the impact of innate and adaptive immune cells on the success of anticancer therapy. In this context we examine the opportunities to exploit host immune responses to boost tumor clearing, and highlight the challenges facing the treatment of advanced metastatic disease.
