Transcranial direct current stimulation (tDCS) over parietal cortex improves associative memory.

Neurobiol Learn Mem 2018 Dec 12. Epub 2018 Dec 12.

Department of Neuroscience, Institute for Medical Research, University of Belgrade, Serbia.

Associative memory plays a key role in everyday functioning, but it declines with normal aging as well as due to various pathological states and conditions, thus impairing quality of life. Associative memory enhancement via neurostimulation over frontal areas resulted in limited success, while posterior stimulation sites seemed to be more promising. We hypothesized that anodal transcranial direct current stimulation (tDCS) of parietal areas would lead to higher performance in associative memory due to high connectivity between posterior parietal cortex (PPC) and hippocampus.

Immune cells in the retina and choroid: Two different tissue environments that require different defenses and surveillance.

Prog Retin Eye Res 2018 Dec 12. Epub 2018 Dec 12.

Department of Anatomy and Developmental Biology, Monash Biomedicine Discovery Institute, Monash University, Clayton, Victoria, Australia.

In the eye immune defenses must take place in a plethora of differing microenvironments ranging from the corneal and conjunctival epithelia facing the external environment to the pigmented connective tissue of the uveal tract containing smooth muscle, blood vessels and peripheral nerves to the innermost and highly protected neural retina. The extravascular environment of the neural retina, like the brain parenchyma, is stringently controlled to maintain conditions required for neural transmission. The unique physiological nature of the neural retina can be attributed to the blood retinal barriers (BRB) of the retinal vasculature and the retinal pigment epithelium, which both tightly regulate the transport of small molecules and restrict passage of cells and macromolecules from the circulation into the retina in a similar fashion to the blood brain barrier (BBB).

The testosterone metabolite 3α-androstanediol inhibits oxidative stress-induced ERK phosphorylation and neurotoxicity in SH-SY5Y cells through an MKP3/DUSP6-dependent mechanism.

Neurosci Lett 2018 Dec 12. Epub 2018 Dec 12.

Department of Biomedical Sciences, Ontario Veterinary College, University of Guelph, 50 Stone Road East, Guelph, Ontario, N1G 2W1, Canada. Electronic address:

Testosterone exerts neuroprotective effects on the brain, but the mechanisms by which these effects are exerted appear to be different in males and females. While in females they involve local conversion to estradiol, in males they may be androgen receptor-dependent, or mediated through metabolism to neurosteroids such as 5α-androstane-3α,17β-diol (3α-diol), which acts through different mechanisms than testosterone itself. Recently, we demonstrated that 3α-diol can protect neurons and neuronal-like cells against oxidative stress-induced neurotoxicity associated with prolonged phosphorylation of the extracellular signal-regulated kinase (ERK).

Pubertal development of estradiol-induced hypothalamic progesterone synthesis.

Horm Behav 2018 Dec 12. Epub 2018 Dec 12.

UCLA DGSOM Dept of Neurobiology, 650 Charles E Young Dr. S, Los Angeles, CA 90095, Laboratory of Neuroendocrinology of the Brain Research Institute, United States of America.

In females, a hallmark of puberty is the luteinizing hormone (LH) surge that triggers ovulation. Puberty initiates estrogen positive feedback onto hypothalamic circuits, which underlie the stimulation of gonadotropin releasing hormone (GnRH) neurons. In reproductively mature female rodents, both estradiol (E2) and progesterone (P4) signaling are necessary to stimulate the surge release of GnRH and LH. Read More

Darpp-32 and t-Darpp protein products of PPP1R1B: old dogs with new tricks.

Biochem Pharmacol 2018 Dec 12. Epub 2018 Dec 12.

Department of Chemistry and Biochemistry, California State University, Los Angeles, CA, USA. Electronic address:

The PPP1R1B gene is located on chromosome 17q12 (39,626,208-39,636,626[GRCh38/hg38]), which codes for multiple transcripts and two experimentally-documented proteins Darpp-32 and t-Darpp. Darpp-32 (Dopamine and cAMP Regulated Phosphoprotein), discovered in the early 1980s, is a protein whose phosphorylation is upregulated in response to cAMP in dopamine-responsive tissues in the brain. It's phosphorylation profile modulates its ability to bind and inhibit Protein Phosphatase 1 activity, which, in turn, controls the activity of hundreds of phosphorylated proteins. Read More

CSF-ApoER2 fragments as a read-out of reelin signaling: Distinct patterns in sporadic and autosomal-dominant Alzheimer disease.

Clin Chim Acta 2018 Dec 12. Epub 2018 Dec 12.

Instituto de Neurociencias de Alicante, Universidad Miguel Hernández-CSIC, 03550 Sant Joan d'Alacant, Spain; Centro de Investigación Biomédica en Red sobre Enfermedades Neurodegenerativas (CIBERNED), Spain. Electronic address:

Reelin is a glycoprotein associated with synaptic plasticity and neurotransmission. The malfunctioning of reelin signaling in the brain is likely to contribute to the pathogenesis of Alzheimer's disease (AD). Reelin binding to Apolipoprotein E receptor 2 (ApoER2) activates downstream signaling and induces the proteolytic cleavage of ApoER2, resulting in the generation of soluble fragments. Read More

MicroRNA-212 promotes the recovery function and vascular regeneration of endothelial progenitor cells in mice with ischemic stroke through inactivation of the notch signaling pathway via downregulating MMP9 expression.

J Cell Physiol 2018 Dec 15. Epub 2018 Dec 15.

Department of Neurology, Cangzhou Central Hospital, Cangzhou, China.

Ischemic stroke is a refractory disease caused by cerebral ischemic injury, which results in brain dysfunction. This study intends to investigate the effects of microRNA-212 (miR-212) on the recovery function and vascular regeneration of endothelial progenitor cells (EPCs) by inactivation of the Notch signaling pathway by binding to matrix metallopeptidase 9 (MMP9) in mice with ischemic stroke. According to the results of database retrieval systems and data analysis, MMP9 was predicted as a gene related to ischemic stroke and miR-212 is a potential regulating mRNA of MMP9. Read More

Nasal insulin administration does not affect hepatic glucose production at systemic fasting insulin levels.

Diabetes Obes Metab 2018 Dec 15. Epub 2018 Dec 15.

Institute for Diabetes Research and Metabolic Diseases of the Helmholtz Center Munich at the University of Tuebingen, Tuebingen, Germany.

Aim: Pharmacologic administration of insulin as nasal spray in humans has demonstrated a modulation of endogenous glucose production via the brain when systemic insulin levels are high. Results are conflicting under fasting insulin concentrations. To evaluate effects of brain insulin on endogenous glucose production in fasting humans with focus on hepatic glucose release, we performed a randomized, placebo controlled, blinded, cross-over experiment.

Individuals with autism constitute a variable population whose members are spread along the autism spectrum. Sub-populations within that spectrum exhibit other conditions, such as anxiety, intellectual disabilities, hyperactivity and epilepsy, with different severities and co-occurrences. Among the genes associated with the increased risk for autism is the methylenetetrahydrofolate-reductase (MTHFR) 677C>T polymorphism, which impairs one-carbon metabolic pathway efficiency. Read More

Unravelling the functional organization of lobula complex in the mantis brain by identification of visual interneurons.

J Comp Neurol 2018 Dec 14. Epub 2018 Dec 14.

Department of Biology, Faculty of Science, Kyushu University, Fukuoka, Japan.

The praying mantis shows broad repertories of visually guided behaviours such as prey recognition and defence against collision. It is likely that neurons in the lobula complex (LOX), the third visual neuropil in the optic lobe, play significant roles in these behaviours. The LOX in the mantis brain consists of five neuropils: outer lobes 1 and 2 (OLO1 and OLO2); anterior lobe (ALO); dorsal lobe, (DLO); and stalk lobe (SLO), and ALO comprise ventral and dorsal subunits, ALO-V and ALO-D.

Cortical interlaminar astrocytes across the therian mammal radiation.

J Comp Neurol 2018 Dec 14. Epub 2018 Dec 14.

Department of Pathology and Laboratory Medicine, UC Davis School of Medicine, Sacramento, CA.

Interlaminar astrocytes (ILA) in the cerebral cortex possess a soma in layer I and extend an interlaminar process that runs perpendicular to the pia into deeper cortical layers. We examined cerebral cortex from 46 species that encompassed most orders of therian mammalians, including 22 primate species. We described two distinct cell types with interlaminar processes that have been referred to as ILA, that we termed pial ILA and supial ILA. Read More
