Scientists find timekeepers of gut’s immune system

October 8, 2019 dna 0
Shift work and jet lag disrupt not just sleep cycles, but feeding and digestive cycles as well. Such disruptions have been linked to risk of obesity, inflammatory bowel disease, infection, and other conditions. Now, researchers have identified an immune cell that helps set the daily rhythms of the gut. The findings open the door to new treatments for digestive ailments targeting such cells.

Scientist designs ‘express courier service’ for immune cells

October 8, 2019 dna 0
A researcher who is currently doing his post-doctoral training at Stanford University, has successfully invented a novel transfection method to deliver DNA into immune cells with minimal stress on these cells. This new technique is expected to boost DNA-based cancer immunotherapy by significantly improving the process of generating high-quality genetically modified immune cells.

Voltage gated calcium channels ‘read’ electric patterns in embryos to create cartilage and bone

October 8, 2019 dna 0
Scientists have revealed how the electrical patterns formed within an embryo initiate a cascade of molecular changes that culminate in the development of cartilage and bone. Prior studies have shown these electrical patterns appear like blueprints of the tissues and organs that eventually take shape as the embryo matures. The new study demonstrates that voltage gated calcium channels ‘read’ the electrical pattern, setting off the expression of genes that guide differentiation to mature cells.
