Genetically engineered probiotics successfully deliver immunotherapies
A new technology enables genetically engineered probiotic bacteria to be used as an efficacious, stable, and safe platform to deliver immunotherapies directly into a variety of tumors in just a single dose. The research was published online on February 12 in Science Translational Medicine. Read More
Phages containing huge amounts of DNA are found around the globe
An inventory of over 350 DNA sequences from phage genomes revealed that these genomes can be over 200,000 base pairs in length and found the largest phage genome ever described at 735,000 base pairs in length. The report published in Nature on February 12, evaluated the prevalence, diversity and ecosystem distribution of phages with large genomes. Read More
T cells work as a team to fight infection
Immune cells may be better at sensing each other than previously thought, according to a new study published in Immunity on February 11. Researchers from Germany, the Netherlands, and the U.K. revealed a mechanism T cells use to work as a team and mutually determine how to fight infections. Read More
Could a plant virus help create a new MRI contrast agent?
What's old is new for University of Texas at Dallas researchers who are resurrecting an organic, biodegradable compound that someday might be the foundation for a nongadolinium-based magnetic resonance imaging (MRI) contrast agent, according to a preclinical study published online on February 5 in Chemical Science.

3D model of human intestines helps simulate leaky gut condition
Researchers are using 3D models of human intestines to simulate leaky gut conditions -- in which microbes and molecules seep out of the intestines, eliciting an immune response. The research, published in Life Science Alliance on February 10, will help identify biomarkers for leaky gut for improved diagnostics and treatment development. Read More
Experts map the future of bioprinting
Bioprinting has rapidly advanced in both techniques and clinical applications, but key challenges still remain for the burgeoning field. A multinational team of researchers offered their recommendations for how to address these hurdles in an in-depth road map article published February 7 in Biofabrication. Read More
Hydrogels enable on-demand production of pharmaceuticals
A first-in-class system that effectively embeds engineered microbes into the solid support of a 3D-printed hydrogel is described in a report published in Nature Communications on February 4. The hydrogel system organizes both individual microbes and groups of microbes for on-demand production of pharmaceuticals. Read More
Chinese researchers mobilize to classify 2019-nCoV
In response to a recent outbreak of the novel coronavirus (2019-CoV), scientists in China have uncovered genetic similarities with severe acute respiratory syndrome (SARS) coronaviruses by analyzing patient samples from the source of the outbreak. Their findings provide crucial evidence that will aid in the classification and identification of 2019-CoV, according to a new report published in Nature on February 3. Read More
Wuhan coronavirus spread may be vastly underestimated
Up to 75,800 people in the city of Wuhan, China, are estimated to be infected with the 2019 novel coronavirus (2019-nCoV), which is vastly more than official reports, according to a mathematical modeling study by Hong Kong experts that was published online January 31 in the Lancet journal.

Brain's immune system blocks blood immune cells from healing spinal injuries
Molecular and computational analysis of immune responses in the central nervous system reveals that the brain's immune system may prevent blood immune cells from entering a lesion site after injury. The research, published online in Science Advances on January 15, may offer new avenues to treat certain neurological diseases such as multiple sclerosis, Alzheimer's disease, and spinal cord injury.
