Cytomegalovirus (CMV) reactivation in immune compromised patients such as those undergoing hematopoietic progenitor cell transplantation (HPCT) and those with HIV infections can cause severe morbidity and mortality despite treatment with appropriate antiviral agents. The recovery of Cytomegalovirus (CMV) specific cytotoxic T lymphocytes (CTL) plays an important role in the reconstitution of CMV specific immunity in immunocompromised patients. Recent studies have reported that CMV reactivation can be successfully treated by adoptive transfer of CMV-specific T cell clones from CMV seropositive donors expanded in vitro with CMV infected fibroblasts or lysates of CMV infected cells. Other studies have used immune dominant CMV proteins or peptides to expand CMV-specific cytotoxic T lymphocytes. This review describes the clinical manifestations of CMV disease in immunocompromised patients, recent advances of antiviral therapy for CMV disease, the principals of the induction of cellular immune response to CMV, and the clinical application of CMV immunotherapy.

Despite the chemotherapy is successful in inducing remission of hematologic malignancy, this disease also has a high probability of relapse; besides, the toxicity of chemotherapy for these patients can not be avoided. Researchers have been attempting to eliminate tumor cells by immunotherapy. Recently, various leukemia-associated antigens (LAA) that are recognized by cytotoxic T cell (CTL) in the context of HLA class I molecules have been identified. These LAA include WT1, PR-3, RHAMM, BCR-ABL and Aur-A. On the basis of these findings, various clinical trials of immunotherapy for hematologic malignancy including tumor peptide vaccination, adoptive T cell therapy, NK cell therapy and dendritic cells-cytokine induced killer (DC-CIK) cell therapy are on going. In this review, the current status and future feasibility of cellular immunotherapy for leukemia are discussed.

Recently immunotherapy for gastrointestinal tumor has rapidly developed, and has improved the effect of cancer comprehensive treatment as an adjunctive therapy in combination with surgery, chemotherapy, and radiation therapy. Adoptive transfer of immune cells is an important treatment method for advanced gastric cancer. In this paper, we reviewed the application of adoptive transfer therapy for advanced gastric cancer in the perioperative period and propose a new model for immunotherapy of advanced gastric cancer based on our experience and the results of clinical experiment.

Chimeric antigen receptor (CAR) T cells have been indicated effective in treating B cell acute lymphoblastic leukemia and non-Hodgkin lymphoma and have shown encouraging results in preclinical and clinical studies. However, CAR T cells have achieved minimal success against solid malignancies because of the additional obstacles of their insufficient migration into tumors and poor amplification and persistence, in addition to antigen-negative relapse and an immunosuppressive microenvironment. Various preclinical studies are exploring strategies to overcome the above challenges. Mobilization of endogenous immune cells is also necessary for CAR T cells to obtain their optimal therapeutic effect given the importance of the innate immune responses in the elimination of malignant tumors. In this review, we focus on the recent advances in the engineering of CAR T cell therapies to restore the immune response in solid malignancies, especially with CAR T cells acting as cellular carriers to deliver immunomodulators to tumors to mobilize the endogenous immune response. We also explored the sensitizing effects of conventional treatment approaches, such as chemotherapy and radiotherapy, on CAR T cell therapy. Finally, we discuss the combination of CAR T cells with biomaterials or oncolytic viruses to enhance the anti-tumor outcomes of CAR T cell therapies in solid tumors.

Although antiretroviral therapy (ART) can reduce the viral load in the plasma to undetectable levels in human immunodeficiency virus (HIV)-infected individuals, ART alone cannot completely eliminate HIV due to its integration into the host cell genome to form viral reservoirs. To achieve a functional cure for HIV infection, numerous preclinical and clinical studies are underway to develop innovative immunotherapies to eliminate HIV reservoirs in the absence of ART. Early studies have tested adoptive T-cell therapies in HIV-infected individuals, but their effectiveness was limited. In recent years, with the technological progress and great success of chimeric antigen receptor (CAR) therapy in the treatment of hematological malignancies, CAR therapy has gradually shown its advantages in the field of HIV infection. Many studies have identified a variety of HIV-specific CAR structures and types of cytolytic effector cells. Therefore, CAR therapy may be beneficial for enhancing HIV immunity, achieving HIV control, and eliminating HIV reservoirs, gradually becoming a promising strategy for achieving a functional HIV cure. In this review, we provide an overview of the design of anti-HIV CAR proteins, the cell types of anti-HIV CAR (including CAR T cells, CAR natural killer cells, and CAR-encoding hematopoietic stem/progenitor cells), the clinical application of CAR therapy in HIV infection, and the prospects and challenges in anti-HIV CAR therapy for maintaining viral suppression and eliminating HIV reservoirs.
