Branching mechanisms shaping dendrite architecture.

Dev Biol 2018 Dec 11. Epub 2018 Dec 11.

The University of Queensland, Queensland Brain Institute, Brisbane, Queensland, 4072, Australia. Electronic address:

A neuron's contribution to the information flow within a neural circuit is governed by the structure of its dendritic arbor. The geometry of the dendritic arbor directly determines synaptic density and the size of the receptive field, both of which influence the firing pattern of the neuron. Importantly, the position of individual dendritic branches determines the identity of the neuron's presynaptic partner and thus the nature of the incoming sensory information. Read More

J Cosmet Dermatol 2018 Dec;17(6):1200-1204

Department of Dermatology & Venereology, Medical School, Zagazig University, Cairo, Egypt.

Skin aging is a complex biological process that arises from two basic processes: intrinsic aging (influenced by genetics factors, cellular metabolism, hormone, and metabolic processes) and extrinsic aging caused by chronic light exposure, pollution, ionizing radiation, chemicals, toxins (Expert Opin Biol Ther. 2008;8:393). Intrinsic aging called also chronological aging is observed in sun-protected skin of elderly persons. Read More

The relationship of mammal survivorship and body mass modeled by metabolic and vitality theories.

Authors:
James J Anderson

2018 Apr 14;60(1-2):111-125. Epub 2018 May 14.

School of Aquatic and Fishery Sciences, University of Washington.

A model describes the relationship between mammal body mass and survivorship by combining replicative senescence theory postulating a cellular basis of aging, metabolic theory relating metabolism to body mass, and vitality theory relating survival to vitality loss and extrinsic mortality. In the combined framework, intrinsic mortality results from replicative senescence of the hematopoietic stem cells and extrinsic mortality results from environmental challenges. Because the model expresses the intrinsic and extrinsic rates with different powers of body mass, across the spectrum of mammals, survivorship changes from Type I to Type II curve shapes with decreasing body mass.

Contrasting impact of corticosteroids on anti-PD-1 immunotherapy efficacy for tumor histologies located within or outside the central nervous system.

Oncoimmunology 2018 6;7(12):e1500108. Epub 2018 Sep 6.

Department of Neurosurgery, Johns Hopkins Hospital, Baltimore, USA.

Immune checkpoint blockade targeting programmed cell death protein 1 (PD-1) is emerging as an important treatment strategy in a growing list of cancers, yet its clinical benefits are limited to a subset of patients. Further investigation of tumor-intrinsic predictors of response and how extrinsic factors, such as iatrogenic immunosuppression caused by conventional therapies, impact the efficacy of anti-PD-1 therapy are paramount. Given the widespread use of corticosteroids in cancer management and their immunosuppressive nature, this study sought to determine how corticosteroids influence anti-PD-1 responses and whether their effects were dependent on tumor location within the periphery versus central nervous system (CNS), which may have a more limiting immune environment.

Amphiregulin Regulates Phagocytosis-Induced Cell Death in Monocytes via EGFR and Matrix Metalloproteinases.

Mediators Inflamm 2018 4;2018:4310419. Epub 2018 Nov 4.

Department of Neonatology, University Children's Hospital, Aachen, Germany.

Neonates are highly susceptible to microbial infections which is partially attributable to fundamental phenotypic and functional differences between effector cells of the adult and neonatal immune system. The resolution of the inflammation is essential to return to tissue homeostasis, but given that various neonatal diseases, such as periventricular leukomalacia, necrotizing enterocolitis, or bronchopulmonary dysplasia, are characterized by sustained inflammation, newborns seem predisposed to a dysregulation of the inflammatory response. Targeted apoptosis of effector cells is generally known to control the length and extent of the inflammation, and previous studies have demonstrated that phagocytosis-induced cell death (PICD), a special type of apoptosis in phagocytic immune cells, is less frequently triggered in neonatal monocytes than in adult monocytes.

Propagation of Extrinsic Fluctuations in Biochemical Birth-Death Processes.

Bull Math Biol 2018 Dec 6. Epub 2018 Dec 6.

Department of Mathematics, University of Utah, Salt Lake City, 84112, USA.

Biochemical reactions are often subject to a complex fluctuating environment, which means that the corresponding reaction rates may themselves be time-varying and stochastic. If the environmental noise is common to a population of downstream processes, then the resulting rate fluctuations will induce statistical correlations between them. In this paper we investigate how such correlations depend on the form of environmental noise by considering a simple birth-death process with dynamical disorder in the birth rate. Read More

Buckling of geometrically confined shells.

Soft Matter 2018 Dec 12. Epub 2018 Dec 12.

Department of Mechanical Engineering, Boston University, Boston, MA 02215, USA.

We study the periodic buckling patterns that emerge when elastic shells are subjected to geometric confinement. Residual swelling provides access to range of shapes (saddles, rolled sheets, cylinders, and spherical sections) which vary in their extrinsic and intrinsic curvatures. Our experimental and numerical data show that when these moderately thick structures are radially confined, a single geometric parameter - the ratio of the total shell radius to the amount of unconstrained material - predicts the number of lobes formed.

Experience leaves a lasting mark on neural circuit function in part through activity-regulated gene (ARG) expression. New genome wide approaches have revealed that ARG programs are highly cell-type-specific, raising the possibility that they mediate different forms of experience-dependent plasticity in different cell types. The cell-type specificity of these gene programs is achieved by a combination of cell-intrinsic mechanisms that determine the transcriptional response of each neuronal subtype to a given stimulus and by cell-extrinsic mechanisms that influence the nature of the stimulus a cell receives.

The terminal cells of the tracheal epithelium in Drosophila melanogaster are one of the few known cell types that undergo subcellular morphogenesis to achieve a stable, branched shape. During the animal's larval stages, the cells repeatedly sprout new cytoplasmic processes. These grow very long, wrapping around target tissues to which the terminal cells adhere, and are hollowed by a gas-filled subcellular tube for oxygen delivery. Read More

Bioengineering approaches to regulate stem cell fates aim to recapitulate the in vivo microenvironment. In recent years, manipulating the micro- and nano-scale topography of the stem cell niche has gained considerable interest for the purposes of controlling extrinsic mechanical cues to regulate stem cell fate and behavior in vitro. Here, we established an optimal nanotopographical system to improve 3-dimensional (3D) differentiation of pancreatic cells from human pluripotent stem cells (hPSCs) by testing gradient-pattern chips of nano-scale polystyrene surface structures with varying sizes and shapes.

Advanced-stage cutaneous T-cell lymphoma (CTCL) is usually a fatal malignancy despite optimal use of currently available treatments. In this preclinical study of novel CTCL therapy, we performed in vitro and ex vivo experiments to determine the efficacy of combination treatment with a panel of BET bromodomain inhibitors (BETi) (JQ1, OTX015, CPI-0610, I-BET762) and HDAC inhibitors (HDACi) (SAHA/Vorinostat, Romidepsin). BETi/HDACi combinations were synergistic (combination index <1) against cell viability and induced G0/G1 cell cycle arrest. Read More

Bispecific antibodies (BsAbs), are potential theranostics. Chemical procedures of preparation of BsAbs, in which two monospecific antibodies are split into half molecules and heterodimerized, continue to attract attention in view of their simplicity. Poor dissociation of antibodies with reduced inter-heavy chain disulfides into half molecules under neutral conditions however restricts the BsAbs formation. Read More

The effect of Pyrroloquinoline quinone and Resveratrol on the Survival and Regeneration of Cerebellar Granular Neurons.

Neurosci Lett 2018 Dec 5;694:192-197. Epub 2018 Dec 5.

Department of Biochemistry, German University in Cairo, Egypt. Electronic address:

The inability of central nervous system (CNS) to regenerate following traumatic brain injury (TBI) can be attributed to apoptotic cell death, inhibitory extrinsic environment, and the limited ability of neurons to regenerate. Thus, fostering the intrinsic regenerative potential and minimizing neuronal cell death could be a promising therapeutic approach. Pyrroloquinoline quinone (PQQ) was previously reported for its neuroprotective and regenerative potential on peripheral nerves. Read More
