    This year’s American Association of Cancer Research (AACR) Annual Meeting, held virtually in April, highlighted exciting research taking place across the cancer research landscape. Below are several key trends and research findings from this year’s meeting:

    • COVID-19 & Cancer
      • SARS-CoV-2 and KSHV: Findings from Zhiqiang Qin et al. from the University of Arkansas for Medical Sciences, Little Rock, AR, USA’s study showed that SARS-CoV-2 proteins and anti-COVID-19 drugs could induce lytic reactivation of Kaposi’s sarcoma-associated herpesvirus (KSHV) and that there was upregulation of ACE2 in AIDS-KS tissues. These observations indicate that KSHV may increase the risk of SARS-CoV-2 and that SARS-CoV-2 may increase the risk of KSHV-associated cancers.
    • Anti-cancer effect mediated by T-cell response
      • T-cell responses are more potent in CIS costimulation. Itziar Otano et al. from CIMA-University of Navarra, Pamplona, Spain presented a study comparing CD137 costimulation in-cis and in-trans with regard to the TCR-CD3-ligating cells. CD137 costimulation in-cis was far superior in terms of T-cell activation, proliferation, and survival, NF-κB signaling, and induction of cell-cycle and DNA damage repair gene expression.
    • Adoptive cell therapy in immuno-oncology research
      • A study conducted by Miles H. Linde et al. from Stanford University, Stanford, CA, USA established a novel cancer vaccination approach utilizing myeloid lineage reprogramming to directly convert cancer cells into tumor reprogramed-APCs (TR-APCs) with broad implications for clinical immuno-oncology. They observed that in vivo immunological response to TR-APC induction revealed oligoclonal T cell expansion and establishment of cancer-specific immunological memory and in vivo TR-APC induction elicits modest extension to overall survival in immunodeficient hosts.
    • CAR-T Therapy Continues to Grab Attention
      • Yufei Wang et al. from Dana-Farber Cancer Institute, Boston, MA, USA reported preclinical data of anti-CD70/CAIX dual-targeting fine-tuned immune restoring (DFIR) CAR-T cells designed to target clear cell renal cell carcinoma (ccRCC) tumor cells without on-target off-tumor side effects. The DFIR-CAR T cells secreted immune checkpoint inhibitor (ICI) monoclonal antibodies at the tumor site and exhibited superior efficacy and safety profiling.
    • Engineered T-cell constructs – Quite the buzz
      • Amorette Barber et al. from Longwood University, Farmville, VA, USA presented on using gamma delta T cells derived from healthy donors and engineered with a chimeric PD-1 receptor (chPD1-gdT cells) to target PDL-1+ tumor cells. chPD1-gdT cells selectively killed PDL-1+ tumor cells with minimal on-target/off-tumor toxicities and without off-target toxicities and will be further assessed in phase I/II clinical trials.
