Correcting each other’s mistakes - why cells stuck together in early evolution
The transition from single cells to multicellular organisms was a key step in evolution. Researchers from Leiden and Amsterdam developed a mathematical model that explains how this transition may have come about. They suspect cooperating cells may correct each other’s mistakes. Publication in eLife…

Specialised immune cells have potential for new cancer immunotherapies
Researchers from Leiden University Medical Center (LUMC) and Netherlands Cancer Institute (NKI) have discovered how specialised immune cells can detect and remove cancers that are ‘invisible’ to the conventional defence mechanisms of the immune system. Their work has been published in Nature. The findings…

Miraculous mechanism allows plant cells to directionally distribute the growth hormone auxin
Leiden and Austrian researchers have succeeded in further uncovering how a plant cell passes on the growth hormone auxin in a directional manner to the next cell. Three proteins that cling together in a bunch appear to be essential for this important transport process. ‘This discovery solves a crucial…

Immunity, Infection and Tolerance
Our immune system protects us against disease, but every now and then, something goes wrong: an enemy invades our bodies or our immune system attacks our own cells and we become ill. Doctors and researchers at the Leiden University Medical Center (LUMC) want to be able to manipulate the immune system…

How oxygen deprivation causes cancer cells to spread
In breast cancer, metastasis rather than the primary tumour is the cause of death. A lack of oxygen in the tumour cells promotes this metastasis, accompanied by a reprogramming of the cell's metabolism. PhD candidate Qiuyu Liu investigated these alterations to get more knowledge about the actionable…

Cancer cell mechanism found to be used against itself
Leiden biophysicists have found a new possible way to attack cancer cells. They have located ‘sinkholes’ on the cells where receptor proteins disappear from the surface. If a drug could push these proteins towards those areas, it would kill the cancer cell.

New cell therapy facility at Leiden Bio Science Park
American pharmaceutical company Bristol Myers Squibb will be building a new (CAR-T) cell therapy facility in the Oegstgeest part of the Leiden Bio Science Park. The company will manufacture and develop CAR T-cell therapy for patients with blood cancer (leukaemia), for example.

Sensing drug responses of single cells using optical tweezers
Light can be used to apply forces on single cells. Focused lasers have been used by physicists to tweeze particles and to manipulate them. These so called “optical tweezers” can be used as mechanical phenotyping tools for characterising the mechanics of materials and living objects.

Development of a Kidney-on-a-Chip Model for Compound Screening and Transport Studies
Pharmaceutical companies, governments and the general public have become increasingly aware that animal models used in drug testing lack vital aspects to serve as an accurate representation of human biology. As models of the human body should become more physiologically relevant, animal models no longer…
