In addition to the better known chimeric antigen receptor (CAR) T cells, ACTs include tumor infiltrating lymphocytes (TIL), cancer antigen-specific T cell receptors (TCRs), and CAR-NK (natural killer) cells. In key historic milestones, several adoptive therapies recently received FDA approvals, including 6 CAR-T products for the treatment of hematologic malignancies and the first TIL therapy for the treatment for metastatic melanoma. The rapid pace of clinical trials in the field and the discoveries they provide are ushering in a new era of cancer immunotherapy. However, the potential complications of these therapies are still not fully understood. In particular, patients receiving ACT may be at increased risk for severe infections due to immunocompromise resulting from their underlying malignancies, which are further compounded by the immune derangements that develop in the setting of cellular immunotherapy and/or the preconditioning treatment needed to enhance ACT efficacy. Moreover, these treatments are being readily implemented at a time following the height of the COVID-19 pandemic, and it remains unclear what additional risks these patients may face from SARS-CoV-2 and similar infections. Here, we examine the evidence for infectious complications with emerging adoptive therapies, and provide a focused review of the epidemiology, complications, and clinical management for COVID-19 in CAR-T recipients to understand the risk this disease may pose to recipients of other forms of ACT.</div></div>","PeriodicalId":21684,"journal":{"name":"Seminars in hematology","volume":"61 5","pages":"Pages 321-332"},"PeriodicalIF":5.0,"publicationDate":"2024-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142393079","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The gene engineering inherent in CAR T-cell manufacture offers an unprecedented opportunity to control cellular characteristics and design products that may overcome these limitations. This review summarises available methods to “tune” CAR T-cells for optimal efficacy and safety. The components of a typical CAR, and the modifications that can influence CAR T-cell function are discussed. Methods of engineering passive, inducible or autonomous control mechanisms into CAR T-cells, allowing selective limitation or enhancement of CAR T-cell activity are reviewed. The impact of manufacturing processes on CAR T-cell function are considered, including methods of limiting CAR T-cell terminal differentiation and exhaustion, and the use of specific T-cell subsets as the CAR T starting material. We discuss the use of multicistronic transgenes and multiplexed gene editing.
