Cancer Cells Form Synaptic Connections with Neurons

GEN | September 23, 2019

In aggressive glioblastoma, cancer cells plug into the brain’s neuronal network and receive impulses that appear to stimulate tumor growth. These impulses, which are transmitted via synaptic connections, may explain how brain tumors spread so quickly. They may also be subject to jamming—that is, to interference by drugs. If so, it may be possible to pull the plug on brain cancer. The shocking discovery that cancer tissue, like brain tissue, may be electrically active was reported by scientists from Heidelberg University Hospital and the German Cancer Research Center. In a paper (“Glutamatergic synaptic input to glioma cells drives brain tumor progression”) that appeared in Nature, these scientists noted that previous research had already established that glioblastoma cells connect with one another rather like neurons. This finding has been extended in the new research, which argues that tumor cells not only interconnect like neurons, they also interconnect with neurons. Even more intriguingly, the interconnections are active. “We report a direct communication channel between neurons and glioma cells in different disease models and human tumors: functional bona fide chemical synapses between presynaptic neurons and postsynaptic glioma cells,” the authors of the Nature article wrote. “These neurogliomal synapses show a typical synaptic ultrastructure, are located on tumor microtubes, and produce postsynaptic currents that are mediated by glutamate receptors of the AMPA subtype.”

Bio-Techne Announces Completion of and Gene Therapy Catapult Analytical Technology (PAT) Consortium

Bio-Techne Corporation | March 20, 2023

Bio-Techne Corporation announced it has completed its participation in the Cell and Gene Therapy Catapult Process Analytical Technology (Catapult PAT) consortium, a multi-year collaboration involving 24 partner companies, technology providers, therapy developers, and charities. The Catapult PAT consortium is the first initiative of this scale and functional expertise with member companies and organizations collaborating to develop cell and gene therapy-specific process analytical technologies. The PAT initiative began in January 2021 with a series of experiments designed to monitor process parameters of an exemplar 8-day T-cell expansion bioprocess using primary T-cells. Data were gathered from five independent analyses to generate an extensive, world-first dataset. An analysis of multiple cytokine targets was conducted using high-plex Luminex® immunoassays and the precision multiplexing Ella™ platform from Bio-Techne. The automated workflow of the Ella platform proved to be particularly amenable to the efficiency, accuracy, and throughput demands inherent in a bioprocess manufacturing environment. With its robust performance in this project, the Cell and Gene Therapy Catapult plans to incorporate Ella™ into an existing CGT Catapult facility to further support scientists in the UK. "As a leader in the forefront of innovative tools to measure cytokines, we are honored to be a part of the Catapult PAT initiative to help advance cell and gene therapy development," said Will Geist, President of Bio-Techne's Protein Sciences Segment. "Bio-Techne remains excited about the potential of these advanced therapies to improve patient outcomes and treat a wide range of diseases that currently have very poor or ineffective treatments." Established by Innovate UK, the Cell and Gene Therapy Catapult fosters collaborations between academia, industry, and healthcare providers to develop new technology and drive innovation. Catapult experts cover all aspects of advanced therapies, from research and development to clinical adoption and every step in between. About Bio-Techne Bio-Techne Corporation is a global life sciences company providing innovative tools and bioactive reagents for the research and clinical diagnostic communities. Bio-Techne products assist scientific investigations into biological processes and the nature and progress of specific diseases. They aid in drug discovery efforts and provide the means for accurate clinical tests and diagnoses.
