Too much or too little: the impact of protein dosage on development
Too much or too little: the impact of protein dosage on development
A recent study carried out at the University of Lausanne reveals that both excess and deficiency of the same protein can lead to severe intellectual impairment. The discovery opens up vital prospects for the early diagnosis of a rare developmental disorder. A team of scientists led by Alexandre Reymond, an expert in human genetics at the Centre intégratif de génomique (CIG) and Professor at the Faculty of Biology and Medicine (FBM) at the University of Lausanne (UNIL), has produced a major breakthrough in the detection of a rare genetic disease.

Bacteria reprogrammed to study bee microbiota
Bacteria reprogrammed to study bee microbiota
Scientists at the University of Lausanne have succeeded in reprogramming a bacterium that can now detect a specific molecule in a bee's intestine and produce a fluorescent protein in response, which can be observed under a microscope. The microorganisms present in the intestine, known as the gut microbiota, play a key role in our development and health.

The role of altered blood vessels in brain tumors
The role of altered blood vessels in brain tumors
In a recent research, scientists have revealed new insights into the complex network of blood vessels in brain metastases, which were not well understood before. They've emphasized a significant increase in a molecule called CD276, known for its role in immune regulation. What's promising is that experimental antibodies targeting CD276 have shown positive results in early trials, suggesting a potential breakthrough in treatment approaches.

Linking rare and common diseases
Linking rare and common diseases
A study conducted at the University of Lausanne and the SIB has demonstrated that a little-studied category of genetic variants, generally associated with serious rare diseases, also influences the risk of more common diseases in the general population. Their results, published in the January 8, 2024 issue of the journal "Genome Medicine", are promising for the development of personalized medicine.

Warrior and nurse ants
Warrior and nurse ants
Matabele ants are able to detect and treat infected wounds in their fellow ants. The work carried out at the University of Lausanne's Department of Ecology and Evolution on this African species is the subject of a publication in "Nature Communications" and a documentary.

How plants determine where light comes from
How plants determine where light comes from
With no visual organs, how can a plant know where light is coming from? In an original study combining biological and engineering expertise, the team led by Prof. Christian Fankhauser at the University of Lausanne, in collaboration with colleagues at EPFL, has deciphered a novel mechanism using the interface between air and water to generate a gradient of light "visible" to the plant.

One mutation can counterbalance another
One mutation can counterbalance another
In most diseases caused by a single gene, the deleterious mutation could be corrected by another mutation, called a "genetic suppressor". This is what researchers at the University of Lausanne, led by Jolanda van Leeuwen, have discovered, opening up potential new therapeutic avenues. Genetic mutations are constantly appearing in the DNA of our cells.

Attention Please ! Recherches sur l’attention et sciences historiques - 10.11.2023
Researchers from the Department of Oncology UNIL-CHUV published a new study in Immunity, showing that machine learning improves the prioritization of cancer specific mutations for cancer immunotherapy. The study *, published in Immunity , was conducted by Markus Müller, a senior scientist in the Immunopeptidomics group headed by Michal Bassani-Sternberg, within the Human Integrated Tumor Immunology Discovery Engine (Hi-TIDe), part of the Ludwig Lausanne branch, which is directed by Pr George Coukos.

The discovery of a new kind of cell revolutionizes neuroscience
A research team from the University of Lausanne and the Wyss Center has discovered a new type of cell essential to brain function. Hybrid in composition and function between the two hitherto known types of brain cells - neurons and glial cells - these cells of a new order are found in several brain regions from mice to humans.

Reversing aging in the blood and immune systems
Reversing aging in the blood and immune systems
As we age, our bodies face many challenges, including declining immune system function and increased vulnerability to various health problems. A study conducted within the UNIL-CHUV Department of Oncology has recently shed light on these challenges. It unveils a potential solution that could have far-reaching implications for aging individuals.

The secrets of folding DNA
The secrets of folding DNA
A study published on August 2, 2023 in "Cell" by a team from the University of Lausanne reveals that the way DNA folds back on itself directly influences the development and functioning of the nervous system. DNA is like a thread of wool which, during development, twists around itself to form a chromosome, a ball of yarn.

How brain cells recycle themselves
A study published on June 5, 2023 in Neuron by a team from the University of Lausanne lifts part of the veil on the autophagy mechanism in neurons and glial cells . Autophagy is an essential process in cellular life: it cleans up the waste produced by the cell's machinery, eliminating useless, defective or toxic components, and recycling those that can be.

How cells feed on RNA
Scientists have discovered that cells can use RNA and its constituent uridine as alternative energy sources to sugar. For better or for worse, as shown by their publication in "Nature Metabolism ". Each cell contains the genetic material necessary for the activity of the organism. RNA, or ribonucleic acid, is an important molecule for making proteins from the instructions contained in the genes.
