Timeline of events pp1390 - 1391 Shraddha Chakradhar doi:10.1038/nm1217-1390 From a worldwide march in favor of science to an increased focus on diversity and gender equality in the workplace, 2017 was a year that was dominated by activism and social causes. Amidst these events, however, were concerns over unproven treatments and emergency funding.

Drugs that made headlines in 2017 pp1392 - 1393 Shraddha Chakradhar doi:10.1038/nm1217-1392 In 2017, cancer drugs once again dominated the news, with many of these medications making headlines for being the first of their kind to gain approval. Beyond cancer, drugs for inflammatory diseases also received attention, for both their successes and their failures.

ADAM10-mediated ephrin-B2 shedding promotes myofibroblast activation and organ fibrosis pp1405 - 1415 David Lagares, Parisa Ghassemi-Kakroodi, Caroline Tremblay, Alba Santos, Clemens K Probst et al. doi:10.1038/nm.4419 TGF-[beta] induces expression of ADAM10, which results in greater shedding of ephrin-B2. This shedding promotes the chemotaxis and activation of myofibroblasts and thus the progression of organ fibrosis.

Targeting the T cell receptor [beta]-chain constant region for immunotherapy of T cell malignancies pp1416 - 1423 Paul M Maciocia, Patrycja A Wawrzyniecka, Brian Philip, Ida Ricciardelli, Ayse U Akarca et al. doi:10.1038/nm.4444 Pule and colleagues identify the TCR [beta]-chain constant region as a new target for chimeric antigen receptor (CAR) T cells in treatment of T cell cancers while potentially preserving a healthy T cell repertoire. They demonstrate that anti-TCRB1 CAR T cells eliminate cancerous TCRB1+ T cells while sparing nearly one-third of normal TCRB2+ T cells.

Human primary liver cancer-derived organoid cultures for disease modeling and drug screening pp1424 - 1435 Laura Broutier, Gianmarco Mastrogiovanni, Monique MA Verstegen, Hayley E Francies, Lena Morrill Gavarro et al. doi:10.1038/nm.4438 Tumor organoids derived from the most common subtypes of primary liver cancer recapitulate the histologic and molecular features of the tissues of origin, even after long-term culture. These in vitro models, as well as those for colorectal cancer reported in Crespo et al. in a previous issue, are amenable for drug screening and allow the identification of therapeutic approaches with potential for cancer treatment.

The activated conformation of integrin [beta]7 is a novel multiple myeloma-specific target for CAR T cell therapy pp1436 - 1443 Naoki Hosen, Yukiko Matsunaga, Kana Hasegawa, Hiroshi Matsuno, Yuki Nakamura et al. doi:10.1038/nm.4431 Hosen et al. identify an active conformation of integrin beta-7 as a cancer-associated antigen in multiple myeloma, and engineer a CAR-T cell that shows efficacy against MM in a mouse model. These findings describe the first conformation-specific CAR-T cell and highlight the potential of conformational targets in cancer immunotherapy.

UCP1-independent signaling involving SERCA2b-mediated calcium cycling regulates beige fat thermogenesis and systemic glucose homeostasis pp1454 - 1465 Kenji Ikeda, Qianqian Kang, Takeshi Yoneshiro, Joao Paulo Camporez, Hiroko Maki et al. doi:10.1038/nm.4429 Calcium cycling induced by the SERCA2b-RyR2 pathway in beige fat cells allows for thermogenic activity independent of UCP1.

A microRNA screen reveals that elevated hepatic ectodysplasin A expression contributes to obesity-induced insulin resistance in skeletal muscle pp1466 - 1473 Motoharu Awazawa, Paula Gabel, Eva Tsaousidou, Hendrik Nolte, Marcus Kruger et al. doi:10.1038/nm.4420 Screening reveals that obesity induces the expression of liver ectodysplasin A, which acts on the muscle to induce insulin resistance.

Selective neuronal lapses precede human cognitive lapses following sleep deprivation pp1474 - 1480 Yuval Nir, Thomas Andrillon, Amit Marmelshtein, Nanthia Suthana, Chiara Cirelli et al. doi:10.1038/nm.4433 In humans, a full night of sleep deprivation causes attenuated and delayed neuronal responses that correlate with impaired cognitive performance.

IRF3 and type I interferons fuel a fatal response to myocardial infarction pp1481 - 1487 Kevin R King, Aaron D Aguirre, Yu-Xiang Ye, Yuan Sun, Jason D Roh et al. doi:10.1038/nm.4428 The massive cell death that occurs during myocardial infarction releases self-DNA and triggers an interferon response in infiltrating leukocytes via a cGAS-STING-IRF3 pathway. Interference with this response[mdash]either by genetic disruption of the pathway or antibody blockade of the type I interferon receptor[mdash]is beneficial in mice subjected to myocardial infarction.

Enhancing the precision of genetic lineage tracing using dual recombinases pp1488 - 1498 Lingjuan He, Yan Li, Yi Li, Wenjuan Pu, Xiuzhen Huang et al. doi:10.1038/nm.4437 Genetic cell-lineage tracing studies in mice are crucial for delineating the contribution of stem and progenitor cells to different cell types, both in disease states and after regenerative therapy. He et al. have developed new genetic lineage-tracing systems that provide more definitive results than the commonly used Cre-based system and show that this new technology can resolve current controversies in the field, as demonstrated by lineage-tracing studies in the heart and liver.

I have ADHD, OCD, depression, primary biliary cirrhosis (autoimmune disease) and ALS. I didn't have health care I just thought it was a stroke, but it started with my voice. When it started to get worse I went to a neurologist. and was diagonised with amyotrophic lateral sclerosis. i was able to walk with assistance nothing was really working to help my condition.I went off the riluzole (with the doctor’s knowledge) and started on amyotrophic lateral sclerosis herbal formula i ordered from Health Herbal Clinic, Just 7 weeks into the Herbal formula treatment I had great improvements with my slurred speech, this is a breakthrough for all amyotrophic lateral sclerosis sufferers, visit Health Herbal Clinic official website www. healthherbalclinic. net or email info@ healthherbalclinic. net.
