Graphic: model of an intestine [09/01/2015] A new study by researchers at Children's Hospital Los Angeles has shown that tissue-engineered small intestine grown from human cells replicates key aspects of a functioning human intestine. The tissue-engineered small intestine they developed contains important elements of the mucosal lining and support structures and even tiny or ultra-structural components like cellular connections.

Photo: Researcher Christoph Vahl in his laboratory [09/01/2015] T cells play an important role in the immune system, destroying pathogens and controlling the body's immune responses. Every T cell has its own special T cell receptor (TCR) on its surface that only recognizes one specific substance. To protect the body, the majority of these autoreactive cells are destroyed before they fully mature.T cell receptor ensures Treg functionality - Read more

How bacteria control their size

Photo: MRSA uniform in size [08/01/2015] Staphylococcus aureus are so uniform in size they look like they were made in a factory. How do the bacteria manage to keep their size so uniform? Scientists have traditionally studied bacteria in large numbers, not individually. Working with tens of millions of cells in a culture flask, they tracked their growth by looking at how much the cells dimmed light passing through a tube. How bacteria control their size - Read more

'Glowing' new nanotechnology guides cancer surgery

IBD: When genetics and environment interact

( Source: MEDICA.de )

[05/01/2015] T-cells are the guardians of our immune system. When they show changes, it can lead to severe inflammatory responses in the body. It is believed that the T-cells in persons who are affected by inflammatory bowel disease don’t work properly. Two proteins that can be found on activated T-cells and that interact with each other are now being analyzed. IBD: When genetics and environment interact - Read more

Researchers target the cell's 'biological clock'

Graphic: Cancer cells in the body [05/01/2015] Cell biologists at UT Southwestern Medical Center have targeted telomeres with a small molecule called 6-thiodG that takes advantage of the cell's 'biological clock' to kill cancer cells and shrink tumor growth. Researchers target the cell's 'biological clock' - Read more

'Radiogenetics' seeks to remotely control cells and genes

( Source: MEDICA.de )

Photo: Colorful cellular structures [18/12/2014] It is the most basic of ways to find out what something does, whether it is an unmarked circuit breaker or an unidentified gene - flip its switch and see what happens. New remote-control technology may offer biologists a powerful way to do this with cells and genes.'Radiogenetics' seeks to remotely control cells and genes - Read more
