On the cover: Our immune system can recognize and attack cancer cells, but the tumor microenvironment is generally immunosuppressive. Ho et al. (pp. 1217–1228) demonstrate that nutrient deprivation of activated T cells is a form of immunosuppression in tumors and that metabolic rewiring of T cells can enhance anti-tumor immune responses. Chang et al. (pp. 1229–1241) find that checkpoint blockade therapy can restore glucose and reduce glycolysis in tumor cells, providing T cells with the necessary nutrients to fight tumor progression. Kleffel et al. (pp. 1242–1256) show that PD-1/PD-L1 signaling has intrinsic functions within tumor cell subpopulations to promote tumor growth. This image entitled “Cancer: The Beautiful Assassin” illustrates the complexity of the tumor microenvironment and the multiple cell types contained within.

  • Making a Difference in Pain

    Sexual dimorphism can be seen at many levels across the animal kingdom. In humans, it is still surrounded by much controversy and myth. While many sex-specific differences are remarkably obvious, others are subtle, complex, or even puzzling. Psychological and socio-cultural factors can also play a role by heavily influencing the perception of these differences. Take pain, for instance.


  • Chris Marshall (1949–2015)

    • Peter W.J. Rigby,
    • Robin A. Weiss
    Chris Marshall, who died on August 8 at age 66, was a world-renowned cell biologist best known for his pioneering contributions to oncogene research and to cell signaling via GTPases, especially to our understanding of tumor cell signaling through the Ras-Raf-Mek-Erk pathway. He spent the whole of his independent research career at the Chester Beatty Laboratories of the Institute of Cancer Research (ICR) in London, where he was Professor of Cell Biology and Head of the Division of Cancer Biology.


  • A Well-Hung Horse: Sired by Knowledge and Imagination

    • Joseph L. Goldstein
    For more than a century, historians of science have been spinning a philosophical roulette wheel, pondering which is more important in the creative process: imagination or knowledge. The most original scientists (and artists) in our day discover newness by blending existing knowledge with imaginative thinking.


  • Deciphering the DNA Damage Response

    • James E. Haber
    This year’s Albert Lasker Basic Medical Research Award honors Evelyn Witkin and Stephen J. Elledge, two pioneers in elucidating the DNA damage response, whose contributions span more than 40 years.
  • Releasing the Brakes on Cancer Immunotherapy

    • Dan R. Littman
    This year’s Lasker∼DeBakey Clinical Research Award goes to James Allison for discovering that antibody blockade of the T cell molecule CTLA-4 unleashes the body’s immune response against malignant tumors. This has led to development of multiple “immune checkpoint therapies” that are prolonging and saving the lives of thousands of cancer patients.


  • Beginner’s Luck

    • Evelyn Witkin
    On June 5, 1944, I discovered a radiation-resistant mutant of E. coli in my first experiment at the Cold Spring Harbor laboratories. That’s where the new field of bacterial genetics was germinating. I was a Columbia University graduate student, there to learn how to handle E. coli so I could do my doctoral research with bacteria.
  • Accidents and Damage Control

    • Stephen J. Elledge
    My work uncovering the eukaryotic DNA damage response pathway is a tale of serendipity and four amino acids. After graduate school at MIT, I joined Ron Davis’s lab as a post-doc initially to work on plants but became interested in developing gene-targeting methods for mammals. I had reasoned, naively, that the protein responsible for homologous recombination in mammals would be related to the master regulator of recombination in bacteria, recA. RecA protein had the ability to initiate recombination in vitro on its own using ssDNA and ATP.
  • Checkpoints

    • James P. Allison
    I cup the harmonica and start playing with the rest of the band—The Checkpoints. The crowd gets on their feet, cheering and dancing to “King Bee.” It was the 2015 annual American Society of Clinical Oncology (ASCO) meeting. The Society for Immunotherapy of Cancer had organized for us to play one night at the House of Blues in Chicago. The place was packed. Immunologists, oncologists, radiologists, pathologists, journalists, and patients attended our gig. They were celebrating. Not just the skills of the band members—all cancer researchers—but the field of cancer immunotherapy and the amazing clinical successes that were just announced at that ASCO meeting.


  • Nutrient Competition: A New Axis of Tumor Immunosuppression

    • Madhusudhanan Sukumar,
    • Rahul Roychoudhuri,
    • Nicholas P. Restifo
    It is thought that cancer cells engage in Warburg metabolism to meet intrinsic biosynthetic requirements of cell growth and proliferation. Papers by Chang et al. and Ho et al. show that Warburg metabolism enables tumor cells to restrict glucose availability to T cells, suppressing anti-tumor immunity.
  • Single-Cell Analysis: The Differences That Kill

    • Savaş Tay
    Using single-cell RNA sequencing, Avraham et al. investigate how variability in macrophage response to infection is controlled by variability within the pathogen population. They find that heterogeneous expression of the Salmonella virulence factor PhoP and subsequent cell-wall modifications lead to the bimodal induction of the interferon-response in infected macrophages.
  • Helping the Help for CD8+ T Cell Responses

    • Sebastian Amigorena
    Eickhoff et al. and Hor et al. use time-lapse intravital microscopy to show an unexpected choreography of CD4+ and CD8+ T cells “dancing” between different dendritic cell sub-populations during priming of cytotoxic immune responses to viruses.
  • Melatonin Lulling Th17 Cells to Sleep

    • Jacob S. Lee,
    • Daniel J. Cua
    In this issue, Farez et al. report that the circadian hormone melatonin, whose levels vary with seasonal changes in night length, shifts the immune response toward an anti-inflammatory state that may explain the seasonal variability of multiple sclerosis disease activity.
  • The Touching Tail of a Mechanotransduction Channel

    • Zachary A. Knecht,
    • Rachelle Gaudet,
    • Paul A. Garrity
    In mechanotransduction, sensory receptors convert force into electrical signals to mediate such diverse functions as touch, pain, and hearing. In this issue of Cell, Zhang et al. present evidence that the fly NompC channel senses mechanical stimuli using its N-terminal tail as a tether between the cell membrane and microtubules.

    • Susan M. Kaech
    High rates of tumor cell glycolysis suppress intratumoral T cell function by depriving T cells of glucose and the downstream metabolite phosphoenolpyruvate (PEP), which is necessary for maximal Ca2+ -NFAT signaling in T cells. Metabolic rewiring of T cells to generate PEP in glucose-poor conditions improves their anti-tumor responses.

    PD-1/PD-L1 signaling has cell-intrinsic functions in certain types of mouse and human tumors, boosting cancer growth and promoting tumorigenesis. This suggests that immunotherapy with PD-1 blockers may produce an effect on tumor growth that is separate from their effect on the immune response.

    Plant biomass provides us with many essential products and an understanding for how it is synthesized is therefore important to support human activities. A central element to plant biomass is the cell wall; a cellular exoskeleton in which the glucan-based polymer cellulose is a prominent component. This paper identifies a protein family whose members are components of the cellulose synthesizing machinery in plants and reveals a mechanism for how plants maintain their biomass producing capacity during saline conditions.

  • Timeline: Sending Out an SOS

    • Brian Plosky
    “Walked out this morning, don't believe what I saw/Hundred billion bottles washed up on the shore”–Sting. When looking at the myriad changes in the transcriptome and proteome during the response to DNA damage, it seems like hundreds of billions of bottles might be washing across your computer screen. Focusing on just the proteomics datasets describing the dynamics of protein modifications that occur in response to DNA damage, there are tens of thousands of post-translational modifications, which you can read about in many papers, including several from Stephen Elledge, one of the recipients of the 2015 Albert Lasker Basic Medical Research Award.
  • Timeline: Checkpoint Blockade

    • Joao Monteiro
    Immune checkpoint therapy, targeting inhibitory pathways in T cells to unleash antitumor immune responses, has led to amazing advances in the clinical care of patients with highly aggressive and otherwise-untreatable cancers. Paraphrasing Jim Allison, the recipient of the 2015 Lasker-DeBakey Clinical Medical Research Award, before we were able to successfully use the immune system to treat cancer, we had to understand the inner workings of the immune response. This timeline highlights key contributions over the past 30 years that constituted essential steps toward the concept of immune checkpoint therapy.
