Muscle Ciliary Neurotrophic Factor Receptor α Contributes to Motor Neuron STAT3 Activation Following Peripheral Nerve Lesion.

Eur J Neurosci 2018 Dec 16. Epub 2018 Dec 16.

Department of Pharmacology and Systems Physiology, University of Cincinnati, Cincinnati, Ohio, USA.

Expression of the ciliary neurotrophic factor (CNTF) receptor essential ligand binding subunit, CNTF receptor α (CNTFRα), is induced in motor neurons and skeletal muscle following peripheral nerve lesion. We previously found muscle CNTFRα promotes motor neuron axon regeneration post-lesion. Both nerve lesion and CNTF administration activate motor neuron signal transducer and activator of transcription 3 (STAT3), a transcription factor implicated in axon growth, suggesting CNTF receptors may contribute to the lesion-induced STAT3 activation.

LARGE expression in different types of muscular dystrophies other than dystroglycanopathy.

BMC Neurol 2018 Dec 15;18(1):207. Epub 2018 Dec 15.

Department of Medical Biology, Hacettepe University Faculty of Medicine, 06100 Sihhiye, Ankara, Turkey.

Background: Alpha-dystroglycan (αDG) is an extracellular peripheral glycoprotein that acts as a receptor for both extracellular matrix proteins containing laminin globular domains and certain arenaviruses. An important enzyme, known as Like-acetylglucosaminyltransferase (LARGE), has been shown to transfer repeating units of -glucuronic acid-β1,3-xylose-α1,3- (matriglycan) to αDG that is required for functional receptor as an extracellular matrix protein scaffold. The reduction in the amount of LARGE-dependent matriglycan result in heterogeneous forms of dystroglycanopathy that is associated with hypoglycosylation of αDG and a consequent lack of ligand-binding activity.

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 expression levels of miRNA-15a and miRNA-16-1 in circulating tumor cells of patients with diffuse large B-cell lymphoma.

Mol Biol Rep 2018 Dec 14. Epub 2018 Dec 14.

Department of Cancer Genetics, Istanbul Faculty of Medicine, Oncology Institute, Istanbul University, Istanbul, Turkey.

MicroRNAs (miRNAs) have major roles in nearly all cellular process including gene expression, and may behave as oncogene or tumor suppressor gene by binding to complementary sequences in the target mRNA. The circulating microRNA-15a (miRNA-15a) and microRNA-16-1 (miRNA-16-1) of 15 healthy adults and of 40 untreated patients diagnosed with diffuse large B-cell lymphoma (DLBC) were recruited to investigate the expression levels. The expression levels of miRNA-15a, and miRNA-16-1 genes of the untreated DLBCL patients, and healthy individuals with matched age, sex and ethnicity were examined. Read More

Time-course study of high fat diet induced alterations in spatial memory, hippocampal JNK, P38, ERK and Akt activity.

Metab Brain Dis 2018 Dec 14. Epub 2018 Dec 14.

Department of Physiology, Faculty of Medicine, Shahid Beheshti University of Medical Sciences, Tehran, Iran.

Consumption of high fat diet (HFD) is a health concern in modern societies, which participate in wide range of diseases. One underlying mechanism in the HFD mediated pathologies is disruption of insulin signaling activity. It is believed that HFD activates several stress signaling molecules such as MAPKs signaling pathway and these molecules participate in harmful effects in different cell populations including hippocampal cells.
