Importance Of The Field: Conventional therapies, including surgery, chemotherapy and radiotherapy have contributed much to cancer treatment. However, these treatment modalities fail in a large proportion of patients, and there is a great need for effective alternate therapies. Adoptive immunotherapy can be effective against some cancers that have failed all other treatment options, even when disease burdens are massive.
Areas Covered In This Review: This review gives a brief introduction of the historical origins of adoptive immunotherapy and then provides details of strategies for increasing the potency of cell transfer. Approaches for enhancing adoptive immunotherapy include: selecting the right type of cell; providing cytokine support; preconditioning patients and tuning the tumor microenvironment. The review also provides insights into the safety, feasibility and costs of this form of therapy.
What The Reader Will Gain: This article will give the reader an appreciation of the potential of adoptive immunotherapy, as well as an understanding of some limitations and current approaches for optimizing the effectiveness of this approach.
Take Home Message: With recent developments in knowledge of the interactions between the immune system and tumors, the field of adoptive immunotherapy is now poised to make dramatic contributions to cancer therapy.

Introduction: The approval of chimeric antigen receptor (CAR) T cell therapies for the treatment of B cell malignancies has fueled the development of numerous cell therapies. However, these cell therapies are complex and costly, and unlike in hematological malignancies, outcomes with most T cell therapies in solid tumors have been disappointing. Here, we present a novel approach to directly program myeloid cells by administering novel TROP2 CAR mRNA encapsulated in lipid nanoparticles (LNPs).

Introduction: T cell Antigen Coupler (TAC) T cells harness all signaling subunits of endogenous T cell receptor (TCR) to trigger T-cell activation and tumor cell lysis, with minimal release of cytokines. Some of the major obstacles to cellular immunotherapy in solid tumors include inefficient cell infiltration into tumors, lack of prolonged cellular persistence, and therapy-associated toxicity.
Methods: To boost the cytotoxic potential of TAC-T cells against solid tumors, we generated a novel NECTIN-4-targeted TAC-T variant, NECTIN-4 TAC28-T, which integrated the co-stimulatory CD28 cytoplasmic region, and compared the anti-tumor activities between NECTIN-4 TAC-T cells and NECTIN-4 TAC28-T cells in vitro and vivo.

In recent years, cancer immunotherapy has received widespread attention due to significant tumor clearance in some malignancies. Various immunotherapy approaches, including vaccines, immune checkpoint inhibitors, oncolytic virotherapy, bispecific T cell engagers, and adoptive T cell transfer, have completed or are undergoing clinical trials for prostate cancer. Despite immune checkpoint blockade's extraordinary effectiveness in treating a variety of cancers, targeted prostate cancer treatment using the immune system is still in its infancy.

Successful immunotherapy relies on both intratumoral and systemic immunity, which is yet to be achieved for most patients with cancer. Here, we identify P4HA1, encoding prolyl 4-hydroxylase 1, as a crucial regulator of CD8 T cell differentiation strongly upregulated in tumor-draining lymph nodes (TDLNs) and hypoxic tumor microenvironment. P4HA1 accumulates in mitochondria, disrupting the tricarboxylic acid (TCA) cycle through aberrant α-ketoglutarate and succinate metabolism, promoting mitochondria unfitness and exhaustion while suppressing progenitor expansion.

Despite recent advances in immunotherapy against B cell malignancies such as BCMA (B cell maturation antigen) and CD19-targeted treatments using soluble T cell-engaging (TCE) antibodies or chimeric antigen receptor T cells (CAR-T), there is still an important number of patients experiencing refractory/relapsed (R/R) disease. Approaches to avoid tumor-intrinsic mechanisms of resistance such as immune pressure-mediated antigen downmodulation, are being broadly investigated. These strategies include BCMA/CD19 dual-targeting therapies, which may be of particular interest to patients with B cell lymphoma and multiple myeloma, where a specific double-positive immature subpopulation is commonly associated with poor prognosis and poor response to current treatments.
