Current Gene Therapy - Volume 18, Issue 1, 2018

Gene therapy has been receiving widespread attention due to its unique advantage in regulating the expression of specific target genes. In the field of cancer gene therapy, modulation of gene expression has been shown to decrease oncogenic factors in cancer cells or increase immune responses against cancer. Due to the macromolecular size and highly negative physicochemical features of plasmid DNA, efficient delive Read More

Introduction: Bone tissue has an intrinsic ability to repair and regenerate itself through a continuous remodelling cycle of resorption of old or damaged bone and deposition of new. However, significant morbidity and mortality arise when bone cannot heal itself. Effective bone regeneration strategy can improve the current clinical therapies of many orthopaedic disorders. Cell activity stimulation, growth factors, and appropri Read More

Introduction: Mesenchymal Stem Cells (MSCs) are promising candidates for nerve tissue engineering. Brain Derived Neurotrophic Factor (BDNF) secreted by MSCs can function to increase neural differentiation and relieve inflammation response. Gene transfection technology is an efficient strategy to increase the secretion levels of cytokines and enhance cellular functions. However, transfection and in vivo gene expression Read More

The optogenetics approach uses a combination of genetic and optical methods to initiate and control functions in specific cells of biological tissues. Since the high-speed control of neuronal activity by irradiating channelrhodopsin-2 with blue light was reported in 2005, tremendous advancement and application of optogenetics in the field of neuroscience, such as in studies that associate neuronal activity with behaviors, have been Read More

Brain-Derived Neurotrophic Factor (BDNF) is a dominant neurotrophic factor in the brain which plays a crucial role in differentiation, regeneration and plasticity mechanisms. Binding of the BDNF to its high-affinity Tropomyosin-related kinase B (TrkB) receptor leads to phosphorylation of TrkB, thus activating the three important downstream intracellular signaling cascades within the neural cells including phosphatidylinositol 3-ki Read More
