T cells are genetically engineered to express CARs, thereby harnessing the antigen-recognition ability of antibodies and effector function of T cells. Target surface molecule selection is crucial for manufacturing CARs. Ideally, a target surface molecule should be restricted to tumor cells and minimally expressed or absent on normal tissues. Different CD19-targeted CAR-T cell therapies have been approved for the treatment of B-cell lymphoid malignancies that are refractory to other therapies, including indolent and aggressive B-cell non-Hodgkin lymphomas (NHL) and B-cell acute lymphoblastic leukemia (B-ALL). Despite impressive results, many patients with aggressive and refractory B-cell malignancies do not respond to or relapse after CD19 CAR-T cell therapies. Thus, several additional strategies are currently being evaluated to overcome these limitations. This review discusses studies on other promising CAR-T cell targets, including CD20, CD22, BAFF-R, ROR1, CD70, BCR complex, kappa/lambda light chains, multitargeted CAR-T cells, and combinations of CAR-T cell therapy with different drugs.</p>","PeriodicalId":39226,"journal":{"name":"Hematology/ Oncology and Stem Cell Therapy","volume":"15 3","pages":"81-93"},"PeriodicalIF":0.0,"publicationDate":"2022-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10414036","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The evolution of CAR designs beyond the conventional structures is necessary to address some of the limitations of conventional CAR therapy and to expand the use of CAR T cells to a wider range of malignancies. There are various obstacles with a wide range of engineering strategies in order to improve the safety, efficacy and applicability of this therapeutic modality. Here we describe details of modular CAR structure with all the necessary domains and what is known about proximal CAR signalling in T cells. Furthermore, the global need for adoptive cell therapy is expanding very rapidly, and there is an urgent increasing demand for fully automated manufacturing methods that can produce large scale clinical grade high quality CAR engineered immune cells. Despite the advances in automation for the production of clinical grade CAR engineered cells, the manufacturing process is costly, consistent and involves multiple steps, including selection, activation, transduction, and Ex-Vivo expansion. Among these complex manufacturing phases, the choice of culture system to generate a high number of functional cells needs to be evaluated and optimized. Here we list the most advance fully automated to semi-automated bioreactor platforms can be used for the production of clinical grade CAR engineered cells for clinical trials but are far from being standardized. New processing options are available and a systematic effort seeking automation, standardization and the increase of production scale, would certainly help to bring the costs down and ultimately democratise this personalized therapy.

To better assess the outcomes of this new infection in this subgroup of susceptible patients, we performed a systematic review and meta-analysis to evaluate the impact of COVID-19 infection on cancer patients. We performed a literature search using PubMed, Web of Science, and Scopus for studies that reported the risk of infection and complications of COVID-19 in cancer patients and retrieved 22 studies (1018 cancer patients). The analysis showed that the frequency of cancer among patients with confirmed COVID-19 was 2.1% (95% confidence interval [CI]: 1.3-3) in the overall cohort. These patients had a mortality of 21.1% (95% CI: 14.7-27.6), severe/critical disease rate of 45.4% (95% CI: 37.4-53.3), intensive care unit (ICU) admission rate of 14.5% (95% CI: 8.5-20.4), and mechanical ventilation rate of 11.7% (95% CI: 5.5-18).
