In the late 1990s the drug gefitinib became a new tool in treating the most common type of lung cancer, called non–small cell lung cancer. But doctors found that even with continued gefitinib treatment, some patients experienced a cancer relapse within a year. For the past several years, researchers have been working to uncover why these patients lost sensitivity to gefitinib and seeking how to overcome resistance to the drug. Kirsten Dorans reports on the strategies scientists are developing to outpace continually evolving cancer.

Receptors identified for hand, foot and mouth virus pp728 - 729

Kunal P. Patel & Jeffrey M. Bergelson

doi:10.1038/nm0709-728

Two receptors have now been identified for the virus behind severe hand, foot and mouth disease (pages 794–797 and 798–801).

Coupling bone degradation to formation pp729 - 731

Jameel Iqbal, Li Sun & Mone Zaidi

doi:10.1038/nm0709-729

To maintain skeletal integrity and prevent fractures, degradation and rebuilding of bone must occur in synchrony. Transforming growth factor-beta1 is now found to coordinate this restructuring process: the molecule is released during bone degradation and stimulates bone rebuilding (pages 757–765).

Targeting lymphotoxin depletes pathogenic T cells pp732 - 733

Anna M. Hansen & Rachel R. Caspi

doi:10.1038/nm0709-732

A monoclonal antibody directed against lymphotoxin-alpha (LT-alpha) expressed by pathogenic T cells can prompt the clearance of these cells from the body (pages 766–773). The findings bring us one step closer to targeting only the cell populations that cause harm in autoimmune diseases while leaving beneficial arms of the immune system largely intact.

Damage control in the nervous system: rehabilitation in a plastic environment pp735 - 736

James W Fawcett & Armin Curt

doi:10.1038/nm0709-735

People with damage to the central nervous system often undergo rehabilitation therapy. James Fawcett and Armin Curt examine how such therapy might work in conjunction with experimental approaches that increase the ability of neurons to form new connections. They discuss how animal studies raise questions about how to test such approaches in people in a field where firm data are already hard to come by. Phillip Popovich and Dana McTigue take a look at a specific type of nervous system damage—spinal cord injury—and argue that the role of the immune system is underappreciated. They also suggest that one common therapy, application of glucocorticoids, might actually exacerbate the condition.

GOAT links dietary lipids with the endocrine control of energy balance pp741 - 745

Henriette Kirchner, Jesus A Gutierrez, Patricia J Solenberg, Paul T Pfluger, Traci A Czyzyk, Jill A Willency, Annette Schürmann, Hans-Georg Joost, Ronald J Jandacek, John E Hale, Mark L Heiman & Matthias H Tschöp

doi:10.1038/nm.1997

It has been a long-held belief that the hormone ghrelin is activated when an animal is hungry, inducing the brain to increase food intake. Now, Matthias Tschöp and his colleagues show in vivo that it is not the deficiency of calories per se that activates ghrelin, but rather the presence of energy-rich medium-chain dietary fats.


Alefacept promotes co-stimulation blockade based allograft survival in nonhuman primates pp746 - 749

Tim A Weaver, Ali H Charafeddine, Avinash Agarwal, Alexandra P Turner, Maria Russell, Frank V Leopardi, Robert L Kampen, Linda Stempora, Mingqing Song, Christian P Larsen & Allan D Kirk

doi:10.1038/nm.1993

Immunosuppressive regimens used to prevent rejection of transplanted organs are associated with many adverse side effects. Weaver et al. report that by combining the use of a CD2-targeting reagent (alefacept) with a co-stimulation blockade–based protocol, they can prolong survival of kidney allografts in macaques while avoiding the use of standard immunosuppressive agents.

A small molecule blocking oncogenic protein EWS-FLI1 interaction with RNA helicase A inhibits growth of Ewing's sarcoma pp750 - 756

Hayriye V Erkizan, Yali Kong, Melinda Merchant, Silke Schlottmann, Julie S Barber-Rotenberg, Linshan Yuan, Ogan D Abaan, Tsu-hang Chou, Sivanesan Dakshanamurthy, Milton L Brown, Aykut Üren & Jeffrey A Toretsky

doi:10.1038/nm.1983

Ewing's sarcoma family tumors are dependent on an oncogenic fusion protein, most commonly EWS-FLI1, which interacts with RNA helicase A (RHA) in transcriptional complexes. Erkizan et al. have identified a small molecule that inhibits the interaction of RHA with EWS-FLI1 and impairs the growth of Ewing's sarcoma xenografts in mice. The findings provide evidence that targeting tumor-specific transcription factors may be a feasible approach to treating cancer.


TGF-beta1–induced migration of bone mesenchymal stem cells couples bone resorption with formation pp757 - 765

Yi Tang, Xiangwei Wu, Weiqi Lei, Lijuan Pang, Chao Wan, Zhenqi Shi, Ling Zhao, Timothy R Nagy, Xinyu Peng, Junbo Hu, Xu Feng, Wim Van Hul, Mei Wan & Xu Cao

doi:10.1038/nm.1979

Bone is a dynamic tissue and requires the precise coordination of formation with loss. Here, Xu Cao and his colleagues show that the bone-chewing activity of osteoclasts results in the local release of active TGF-beta1 from the surface of the bone, inducing the migration of nearby bone-forming osteoblastic progenitor cells to this resorbed region. In this manner, proper matching of the localized rates of bone loss and bone creation is ensured (pages 729–731).

Targeted depletion of lymphotoxin-alpha–expressing TH1 and TH17 cells inhibits autoimmune disease pp766 - 773

Eugene Y Chiang, Ganesh A Kolumam, Xin Yu, Michelle Francesco, Sinisa Ivelja, Ivan Peng, Peter Gribling, Jean Shu, Wyne P Lee, Canio J Refino, Mercedesz Balazs, Andres Paler-Martinez, Allen Nguyen, Judy Young, Kai H Barck, Richard A D Carano, Ron Ferrando, Lauri Diehl, Devavani Chatterjea & Jane L Grogan

doi:10.1038/nm.1984

B cell–depleting antibodies have therapeutic efficacy against arthritis. Here Jane Grogan and her colleagues report a new approach to depleting pathogenic T cells. They show that lymphotoxin-alpha is upregulated on the surface of activated TH1 and TH17 CD4+ cells, which have a pathogenic role in several autoimmune diseases, and a monoclonal antibody targeted to lymphotoxin-a can inhibit collagen-induced arthritis and EAE in mice (pages 732–733).

Tenascin-C is an endogenous activator of Toll-like receptor 4 that is essential for maintaining inflammation in arthritic joint disease pp774 - 780

Kim Midwood, Sandra Sacre, Anna M Piccinini, Julia Inglis, Annette Trebaul, Emma Chan, Stefan Drexler, Nidhi Sofat, Masahide Kashiwagi, Gertraud Orend, Fionula Brennan & Brian Foxwell

doi:10.1038/nm.1987

TLR4 has a key role in driving inflammation in mouse models of arthritis and may also have a role in the human disease. The extracellular matrix protein tenascin-C is upregulated in the joints of individuals with rheumatoid arthritis. Here Kim Midwood and her colleagues show that tenascin-C is an endogenous activator of TLR4 and that it contributes to the maintenance of arthritis in mice.


A selective inhibitor of the immunoproteasome subunit LMP7 blocks cytokine production and attenuates progression of experimental arthritis pp781 - 787

Tony Muchamuel, Michael Basler, Monette A Aujay, Erika Suzuki, Khalid W Kalim, Christoph Lauer, Catherine Sylvain, Eileen R Ring, Jamie Shields, Jing Jiang, Peter Shwonek, Francesco Parlati, Susan D Demo, Mark K Bennett, Christopher J Kirk & Marcus Groettrup

doi:10.1038/nm.1978

Christopher Kirk and his colleagues have developed the first specific inhibitor of the immunoproteasome. They find that the immunoproteasome has a major role in regulating cytokine production, as well as antigen presentation, and their inhibitor has good efficacy in animal models of arthritis.

Activation of kinin receptor B1 limits encephalitogenic T lymphocyte recruitment to the central nervous system pp788 - 793

Ulf Schulze-Topphoff, Alexandre Prat, Timour Prozorovski, Volker Siffrin, Magdalena Paterka, Josephine Herz, Ivo Bendix, Igal Ifergan, Ines Schadock, Marcelo A Mori, Jack Van Horssen, Friederike Schröter, Alina Smorodchenko, May Htwe Han, Michael Bader, Lawrence Steinman, Orhan Aktas & Frauke Zipp

doi:10.1038/nm.1980

Modulating the entry of inflammatory T cells into the brain could be one way to treat the autoimmune disease multiple sclerosis. Now, Frauke Zipp and colleagues demonstrate that activation of kinin receptor B1 can block autoimmune T cell migration into the brain and can therefore inhibit experimental autoimmune encephalomyelitis in mice.


Human P-selectin glycoprotein ligand-1 is a functional receptor for enterovirus 71 pp794 - 797

Yorihiro Nishimura, Masayuki Shimojima, Yoshio Tano, Tatsuo Miyamura, Takaji Wakita & Hiroyuki Shimizu

doi:10.1038/nm.1961

Enterovirus 71 (EV71) causes hand, foot and mouth disease, a mild infectious disease that can, however, occasionally lead to severe neurological impairments. These two studies, by Nishimura et al. and Yamayoshi et al., independently identify two different receptors for EV71—P-selectin glycoprotein ligand-1 ((PSGL-1) and scavenger receptor class B, member 2 (SCARB2) (pages 728–729) and (pages 798–801).

Hematopoietic colony–stimulating factors mediate tumor-nerve interactions and bone cancer pain pp802 - 807

Matthias Schweizerhof, Sebastian Stösser, Martina Kurejova, Christian Njoo, Vijayan Gangadharan, Nitin Agarwal, Martin Schmelz, Kiran Kumar Bali, Christoph W Michalski, Stefan Brugger, Anthony Dickenson, Donald A Simone & Rohini Kuner

doi:10.1038/nm.1976

Pain is one of the many debilitating side effects of cancer. Now, Rohini Kuner and her colleagues show that blocking hematopoietic colony-stimulating factor signaling on neurons can inhibit pain caused by bone cancer.


Wnt signaling arrests effector T cell differentiation and generates CD8+ memory stem cells pp808 - 813

Luca Gattinoni, Xiao-Song Zhong, Douglas C Palmer, Yun Ji, Christian S Hinrichs, Zhiya Yu, Claudia Wrzesinski, Andrea Boni, Lydie Cassard, Lindsay M Garvin, Chrystal M Paulos, Pawel Muranski & Nicholas P Restifo

doi:10.1038/nm.1982

The Wnt pathway has a central role in stem cell regulation. Gattinoni et al. now show that activation of the Wnt signaling cascade in naive CD8+ T cells blocks their differentiation into effector T cells and triggers instead a memory stem cell–like phenotype. These T memory stem cells show enhanced antitumor efficacy in mice compared with other T cell subsets, arguing for their further evaluation in adoptive immunotherapies (pages 731–732).
