In this Review, the authors highlight mechanisms through which cell transplantation is thought to promote functional improvements and the obstacles to making cell transplantation a viable therapy. | | Advertisement | | Portable fNIRS System

They identify neurodevelopmental deficits in HD cells that can be corrected in cells and in vivo with a small molecule. | | | | Purine synthesis promotes maintenance of brain tumor initiating cells in glioma pp661 - 673 Xiuxing Wang, Kailin Yang, Qi Xie, Qiulian Wu, Stephen C Mack et al. doi:10.1038/nn.4537 Brain tumor initiating cells (BTICs) utilize high-affinity glucose uptake, which is normally active in neurons to maintain energy demands and self-renew. Leveraging metabolomic and genomic analyses, Wang et al. report that de novo purine biosynthesis reprograms BTIC metabolism, revealing a potential point of fragility amenable to targeted cancer therapy. | | | | Regulatory T cells promote myelin regeneration in the central nervous system pp674 - 680 Yvonne Dombrowski, Thomas O'Hagan, Marie Dittmer, Rosana Penalva, Sonia R Mayoral et al. doi:10.1038/nn.4528 Regeneration of myelin is a dynamic, yet enigmatic process. Dombrowski et al. uncover a central role for regulatory T (Treg) cells in driving oligodendrocyte differentiation, in part via CCN3, a novel factor in Treg function and oligodendrocyte biology. This identifies Treg cells as key cellular players in efficient remyelination. | | | | α-Synuclein promotes dilation of the exocytotic fusion pore pp681 - 689 Todd Logan, Jacob Bendor, Chantal Toupin, Kurt Thorn and Robert H Edwards doi:10.1038/nn.4529 The authors used knockout mice to demonstrate the normal function of the protein α-synuclein, which has a central role in Parkinson's and other neurodegenerative diseases. The presynaptic protein promoted dilation of the exocytotic fusion pore, and mutations that cause Parkinson's disease specifically impaired this normal function.

The authors found that neural activation during learning triggers long-lasting transcription of a specific neurexin-1 splice isoform, enabling retention of hippocampus-dependent memory. This process was mediated by signaling through the AMPK pathway leading to histone modifications. | | | | C1 neurons mediate a stress-induced anti-inflammatory reflex in mice pp700 - 707 Chikara Abe, Tsuyoshi Inoue, Mabel A Inglis, Kenneth E Viar, Liping Huang et al. doi:10.1038/nn.4526 Acute stress elicits physiological and behavioral responses that enhance survival. This study in mice shows that stress reduces tissue injury in a model of renal ischemia-reperfusion injury by activating an anti-inflammatory response via the sympathetic system and the spleen. C1 neurons located in the brainstem mediate this protective effect of stress. | | | | GLP-1 acts on habenular avoidance circuits to control nicotine intake pp708 - 716 Luis M Tuesta, Zuxin Chen, Alexander Duncan, Christie D Fowler, Masago Ishikawa et al. doi:10.1038/nn.4540 Nicotine has rewarding effects that motivate its consumption. In addition to these rewarding effects, nicotine also has aversive properties that motivate its avoidance. Here the authors identify a pathway in the brain that regulates nicotine avoidance. Adaptive responses in this and other aversion-related pathways may contribute to the development of tobacco addiction. | | | | Capillary K+-sensing initiates retrograde hyperpolarization to increase local cerebral blood flow pp717 - 726 Thomas A Longden, Fabrice Dabertrand, Masayo Koide, Albert L Gonzales, Nathan R Tykocki et al. doi:10.1038/nn.4533 Longden et al. demonstrate that brain capillaries function as a vast sensory web, monitoring neuronal activity by sensing K+ and translating this into a KIR-channel-mediated regenerative retrograde hyperpolarizing signal that propagates to upstream arterioles to drive vasodilation and an increase in blood flow into the capillary bed.

The authors report that granule cells encode multisensory representations that evolve with learning into a predictive motor signal. This activity may help the cerebellum implement a forward model for action.

Here the authors show that learning to predict neutral events is also driven by prediction errors and that such value-neutral associative learning is also likely mediated by dopaminergic error signals. | | | | The effect of face patch microstimulation on perception of faces and objects pp743 - 752 Sebastian Moeller, Trinity Crapse, Le Chang and Doris Y Tsao doi:10.1038/nn.4527 Scientists have long debated the extent to which different brain regions are specialized for specific tasks. Here the authors show that electrical microstimulation of face-selective brain regions in the temporal lobe of monkeys distorts the animal's percept not just of faces but also of certain non-face objects including round objects.

The treatment of murine intracranial malignant gliomas with these cells demonstrates their potential clinical use. These microglia-like cells will enable further studies into the role of microglia in health and disease. | | Top | | | Advertisement | | Open for Submissions An interdisciplinary journal dedicated to publishing high-quality open research relevant to all aspects of schizophrenia and psychosis.

With ALS,(amyotrophic lateral sclerosis) my first sign that something was wrong, was my slurred speech. And then the inability to eat without getting choked, strangled, and coughing. I didn't have health care I just thought it was a stroke, When it started to get worse I went to a neurologist. I was given medications like riluzole oral to slow down the progress of the disease, nothing was really working to help my condition. Finally i started on amyotrophic lateral sclerosis herbal formula i purchased from Health Herbal Clinic, i read alot of positive reviews from other patients who used the ALS herbal treatment. I used the herbal remedy for 7 weeks, its effects on ALS is amazing, all my symptoms gradually faded away, i feed very more freely by myself now! (Visit www. healthherbalclinic. weebly. com or email at healthherbalclinic@ gmail. com) I recommend this COPD herbal formula for all Parkinson's Patients.
