Special Issue Information

Dear Colleagues,

Since the 2018 Nobel Prize in Physiology or Medicine was awarded for the discovery of cancer therapy by inhibition of negative immune regulation, targeting immune response signaling via immune checkpoint blockade molecules such as programmed cell death-1 and other cell surface molecules has become an attractive approach for drug development. To specifically suppress immunological or biological function of molecules involved in disease pathogenesis, monoclonal antibodies (mAbs) have been considered as immunotherapeutic and prophylactic drugs against a variety of diseases such as tumors, inflammatory disorders including autoimmune diseases, and virus infection-associated diseases.While many drug candidates are developed with promising results in pre-clinical studies, the majority are never approved, mainly due to severe adverse effects in clinical trials. Thus, further improvement of drug design to increase therapeutic efficacy while exhibiting less toxicity is both challenging and urgently required.

In this Special Issue of Vaccines, we focus on recent immunotherapeutic drug development, covering not only mAbs and its various applications, such as antibody-drug conjugates and single chain fragment variables, but also biologics and chemical compounds that regulate or modulate immune responses, which can also be utilized as vaccines or adjuvants targeting factors in the above diseases. In the area of immunopharmacology, we also hope to discuss strategies for overcoming issues related to adverse effects, leading to the improvement of therapeutic agents. Naturally, we also welcome original articles and reviews covering conventional immunopharmacological studies looking towards identification of novel drug targets and factors, or elucidating their mechanisms of action during immune reactions.

Adult T-cell leukemia (ATL) is a CD4+ T-cell neoplasm caused by human T-cell leukemia virus type I. As the prognosis for patients with ATL remains extremely poor due to resistance to conventional chemotherapy regimens, introduction of novel therapeutic agents is needed. Previous studies have reported that nucleosides 2′-deoxy-2′-methylidenecytidine (DMDC) and its derivative 2′-deoxy-2′-methylidene-5-fluorocytidine (FDMDC) exhibit antitumor activities in T-cell acute lymphoblastic leukemia (T-ALL) and solid tumor cell lines. Another nucleoside, 1-(2-azido-2-deoxy-β-D-arabinofuranosyl)cytosine (cytarazid), is considered a therapeutic drug with antitumor activity in human solid tumors. In this study, we investigated the effects of these nucleosides on cell growth in vitro and in vivo using relevant leukemia cell lines and NOD/Shi-scid, IL-2Rgnull (NOG) mice, respectively. The nucleosides demonstrated significant cytotoxic effects in ATL and T-ALL cell lines. Intraperitoneal administration of FDMDC and DMDC into tumor-bearing NOG mice resulted in significant suppression of tumor growth without lethal side effects. Our findings support a therapeutic application of these nucleosides against tumor progression by targeting DNA polymerase-dependent DNA synthesis in patients with ATL. Full article
