TL;DR: A missense mutation in the gene encoding fused in sarcoma (FUS) in a British kindred, linked to ALS6, is identified, which suggests that a common mechanism may underlie motor neuron degeneration.
Abstract: Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease that is familial in 10% of cases. We have identified a missense mutation in the gene encoding fused in sarcoma (FUS) in a British kindred, linked to ALS6. In a survey of 197 familial ALS index cases, we identified two further missense mutations in eight families. Postmortem analysis of three cases with FUS mutations showed FUS-immunoreactive cytoplasmic inclusions and predominantly lower motor neuron degeneration. Cellular expression studies revealed aberrant localization of mutant FUS protein. FUS is involved in the regulation of transcription and RNA splicing and transport, and it has functional homology to another ALS gene, TARDBP, which suggests that a common mechanism may underlie motor neuron degeneration.

TL;DR: It is proposed that glutathione functions to stabilise enzymes of the Calvin cycle, and it may also act to keep ascorbic acid in chloroplasts in the reduced form.
Abstract: Both glutathione and an NADPH-dependent glutathione reductase are present in spinach (Spinacia oleracea L.) chloroplasts. It is proposed that glutathione functions to stabilise enzymes of the Calvin cycle, and it may also act to keep ascorbic acid in chloroplasts in the reduced form.

TL;DR: A grading system of definite, probable, and possible neuropathic pain is proposed, which includes the grade possible, which can only be regarded as a working hypothesis, and the grades probable and definite, which require confirmatory evidence from a neurologic examination.
Abstract: Pain usually results from activation of nociceptive afferents by actually or potentially tissue-damaging stimuli. Pain may also arise by activity generated within the nervous system without adequate stimulation of its peripheral sensory endings. For this type of pain, the International Association for the Study of Pain introduced the term neuropathic pain, defined as "pain initiated or caused by a primary lesion or dysfunction in the nervous system." While this definition has been useful in distinguishing some characteristics of neuropathic and nociceptive types of pain, it lacks defined boundaries. Since the sensitivity of the nociceptive system is modulated by its adequate activation (e.g., by central sensitization), it has been difficult to distinguish neuropathic dysfunction from physiologic neuroplasticity. We present a more precise definition developed by a group of experts from the neurologic and pain community: pain arising as a direct consequence of a lesion or disease affecting the somatosensory system. This revised definition fits into the nosology of neurologic disorders. The reference to the somatosensory system was derived from a wide range of neuropathic pain conditions ranging from painful neuropathy to central poststroke pain. Because of the lack of a specific diagnostic tool for neuropathic pain, a grading system of definite, probable, and possible neuropathic pain is proposed. The grade possible can only be regarded as a working hypothesis, which does not exclude but does not diagnose neuropathic pain. The grades probable and definite require confirmatory evidence from a neurologic examination. This grading system is proposed for clinical and research purposes.

TL;DR: A unique cellular gene, CEM15, is described, whose transient or stable expression in cells that do not normally express Cem15 recreates this phenotype, but whose antiviral action is overcome by the presence of Vif.
Abstract: Viruses have developed diverse non-immune strategies to counteract host-mediated mechanisms that confer resistance to infection. The Vif (virion infectivity factor) proteins are encoded by primate immunodeficiency viruses, most notably human immunodeficiency virus-1 (HIV-1). These proteins are potent regulators of virus infection and replication and are consequently essential for pathogenic infections in vivo. HIV-1 Vif seems to be required during the late stages of virus production for the suppression of an innate antiviral phenotype that resides in human T lymphocytes. Thus, in the absence of Vif, expression of this phenotype renders progeny virions non-infectious. Here, we describe a unique cellular gene, CEM15, whose transient or stable expression in cells that do not normally express CEM15 recreates this phenotype, but whose antiviral action is overcome by the presence of Vif. Because the Vif:CEM15 regulatory circuit is critical for HIV-1 replication, perturbing the circuit may be a promising target for future HIV/AIDS therapies.

TL;DR: Heterozygous rare variants in TREM2 are associated with a significant increase in the risk of Alzheimer's disease.
Abstract: BACKGROUND:
Homozygous loss-of-function mutations in TREM2, encoding the triggering receptor expressed on myeloid cells 2 protein, have previously been associated with an autosomal recessive form of early-onset dementia.
METHODS:
We used genome, exome, and Sanger sequencing to analyze the genetic variability in TREM2 in a series of 1092 patients with Alzheimer's disease and 1107 controls (the discovery set). We then performed a meta-analysis on imputed data for the TREM2 variant rs75932628 (predicted to cause a R47H substitution) from three genomewide association studies of Alzheimer's disease and tested for the association of the variant with disease. We genotyped the R47H variant in an additional 1887 cases and 4061 controls. We then assayed the expression of TREM2 across different regions of the human brain and identified genes that are differentially expressed in a mouse model of Alzheimer's disease and in control mice.
RESULTS:
We found significantly more variants in exon 2 of TREM2 in patients with Alzheimer's disease than in controls in the discovery set (P=0.02). There were 22 variant alleles in 1092 patients with Alzheimer's disease and 5 variant alleles in 1107 controls (P<0.001). The most commonly associated variant, rs75932628 (encoding R47H), showed highly significant association with Alzheimer's disease (P<0.001). Meta-analysis of rs75932628 genotypes imputed from genomewide association studies confirmed this association (P=0.002), as did direct genotyping of an additional series of 1887 patients with Alzheimer's disease and 4061 controls (P<0.001). Trem2 expression differed between control mice and a mouse model of Alzheimer's disease.
CONCLUSIONS:
Heterozygous rare variants in TREM2 are associated with a significant increase in the risk of Alzheimer's disease. (Funded by Alzheimer's Research UK and others.).
