Alternative CAR Therapies: Recent Approaches in Engineering Chimeric Antigen Receptor Immune Cells to Combat Cancer. Biomedicines 2022; 10:biomedicines10071493. [PMID: 35884798 PMCID: PMC9313317 DOI: 10.3390/biomedicines10071493] [Citation(s) in RCA: 15] [Impact Index Per Article: 7.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/28/2022] [Revised: 06/17/2022] [Accepted: 06/21/2022] [Indexed: 02/08/2023] Open
Abstract
For nearly three decades, chimeric antigen receptors (CARs) have captivated the interest of researchers seeking to find novel immunotherapies to treat cancer. CARs were first designed to work with T cells, and the first CAR T cell therapy was approved to treat B cell lymphoma in 2017. Recent advancements in CAR technology have led to the development of modified CARs, including multi-specific CARs and logic gated CARs. Other immune cell types, including natural killer (NK) cells and macrophages, have also been engineered to express CARs to treat cancer. Additionally, CAR technology has been adapted in novel approaches to treating autoimmune disease and other conditions and diseases. In this article, we review these recent advancements in alternative CAR therapies and design, as well as their mechanisms of action, challenges in application, and potential future directions.

Biomedicines 2021; 9:biomedicines9010059. [PMID: 33435454 PMCID: PMC7827151 DOI: 10.3390/biomedicines9010059] [Citation(s) in RCA: 56] [Impact Index Per Article: 18.7] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/08/2020] [Revised: 12/28/2020] [Accepted: 12/31/2020] [Indexed: 02/06/2023] Open
Abstract
Adoptive cell transfer (ACT) has long been at the forefront of the battle with cancer that began last century with the therapeutic application of tumor-infiltrating lymphocytes (TILs) against melanoma. The development of novel ACT approaches led researchers and clinicians to highly efficient technologies based on genetically engineered T lymphocytes, with chimeric antigen receptor (CAR)-T cells as the most prominent example. CARs consist of an extracellular domain that represents the single-chain variable fragment (scFv) of a monoclonal antibody (mAb) responsible for target recognition and the intracellular domain, which was built from up to several signaling motifs that mediated T cell activation. The number of potential targets amenable for CAR-T cell therapy is expanding rapidly, which means that the tremendous success of this approach in oncology could be further translated to treating other diseases. In this review, we outlined modern trends and recent developments in CAR-T cell therapy from an unusual point of view by focusing on diseases beyond cancer, such as autoimmune disorders and viral infections, including SARS-CoV-2.

Development of CAR-T cells for long-term eradication and surveillance of HIV-1 reservoir. Curr Opin Virol 2019; 38:21-30. [PMID: 31132749 DOI: 10.1016/j.coviro.2019.04.004] [Citation(s) in RCA: 19] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/05/2019] [Revised: 04/18/2019] [Accepted: 04/19/2019] [Indexed: 12/21/2022]
Abstract
Human immunodeficiency virus type 1 (HIV-1) reservoir is a pool of latently infected cells harboring replication-competent proviral DNA that limits antiretroviral therapy. Suppression of HIV-1 by combination antiretroviral therapy (cART) delays progression of the disease but does not eliminate the viral reservoir, necessitating lifetime daily administration of antiretroviral drugs. To achieve durable suppression of viremia without daily therapy, various strategies have been developed, including long-acting antiretroviral drugs (LA-ARVs), broadly neutralizing antibodies (bNAbs), and chimeric antigen receptor T (CAR-T) cells. Here, we summarize and discuss recent breakthroughs in CAR-T cell therapies toward the eradication of HIV-1 reservoir. Although substantial challenges exist, CAR-T cell technology may serve as a promising strategy toward HIV-1 functional cure.

Bispecific T cell engaging antibody constructs targeting a universally conserved part of the viral M2 ectodomain cure and prevent influenza A virus infection. Antiviral Res 2017; 141:155-164.

Abstract
The ectodomain of the influenza A matrix protein 2 (M2e) is highly conserved amongst all influenza virus A subtypes. M2e is present on the surface of influenza A virus-infected cells, and therefore a suitable target for broadly protective therapies. We designed bispecific T cell engaging (BiTE®) antibody constructs specific for M2e by genetically fusing a single chain variable fragment (scFv) derived from an M2e-specific murine monoclonal antibody with a CD3ɛ-specific scFv. These so-called FLU BiTE® antibody constructs selectively mediate T cell dependent lysis of M2-expressing and influenza A virus infected cells and protect BALB/c mice against challenge with different influenza A virus subtypes. By humanizing the M2e-binding scFv, we generated human-like FLU BiTE® antibody constructs, with increased in vitro cytotoxic activity and in vivo protective capacity against influenza A virus infection. FLU BiTE® antibody constructs represent a promising new curative and prophylactic treatment option for influenza disease.

Abstract
Viral infections and opportunistic fungal pathogens represent a major menace for immunocompromised patients. Despite the availability of antifungal and antiviral drugs, mortality in these patients remains high, underlining the need of novel therapeutic options based on completely different strategies. This review describes the potential of several T-cell-based therapeutic approaches in the prophylaxis and treatment of infectious diseases with a particular focus on persistent viral infections and opportunistic fungal infections, as these mostly affect immunocompromised patients.

Abstract
Many emerging or known, chronic viral diseases are caused by enveloped viruses. The review discusses research driven development of antivirals that became recently available or are in clinical evaluation. The main focus is on antiviral strategies with a broader therapeutic range, and on novel immune based therapeutics. Broad-spectrum antivirals will help to react faster to newly emerging viral diseases. Targeting immune cells against infected cells can restore immune responses in chronic infections.
Enveloped viruses pose an important health threat because most of the persistent and many emerging viruses are enveloped. In particular, newly emerging viruses create a need to develop broad-spectrum antivirals, which usually are obtained by targeting host cell factors. Persistent viruses have developed efficient strategies to escape host immune control, and treatment options are limited. Targeting host cell factors essential for virus persistence, or immune-based therapies provide alternative approaches. In this review, we therefore focus on recent developments to generate antivirals targeting host cell factors or immune-based therapeutic approaches to fight infections with enveloped viruses.
