Discovery of an innate immunological memory in the intestine
Discovery of an innate immunological memory in the intestine
The innate immune system plays a crucial role in regulating host-microbe interactions, and especially in providing protection against pathogens that invade the mucosa. Using an intestinal infection model, scientists from the Institut Pasteur and Inserm discovered that innate effector cells - group 3 innate lymphoid cells - act not only during the early stages of infection but can also be trained to develop an innate form of immunological memory that can protect the host during reinfection.

Better Understanding the Role of a White Blood Cell Type in SARS-CoV-2 Immune Response
Better Understanding the Role of a White Blood Cell Type in SARS-CoV-2 Immune Response
Although the response of various immune cells to SARS-CoV-2 infection has been relatively well studied, that of basophils (a category of white blood cells) had not been characterized yet - mainly because of their rarity in that they represent around 0.5% of the body's white blood cells. In a new study, researchers from Inserm, Sorbonne Université, Université de Paris, CNRS, Institut Pasteur and Efrei describe how basophils respond to SARS-CoV-2 infection.

Defeating leukaemia cells by depriving them of energy
Selective activation of the AMPK enzyme would lead to the death of leukaemia cells (in purple in this image). Jérôme Tamburini / UNIGE High resolution pictures A Swiss-French team that includes scientists has discovered how to trigger apoptosis in leukaemia cells by disrupting their energy maintenance mechanism.

A Novel Immunotherapy Approach Redirects Epstein-Barr Antibodies toward Disease-Causing Cells
A Novel Immunotherapy Approach Redirects Epstein-Barr Antibodies toward Disease-Causing Cells
Monoclonal antibody therapy can be very effective in treating numerous illnesses, such as cancers, chronic inflammatory conditions, and infectious diseases. However, it is costly and uses molecules that are complicated to produce. Therefore, it is essential to identify new therapeutic alternatives so that as many patients as possible get the treatments they need.

Improvement in the Health of Two Infants with Severe Disharmonious Overgrowth Syndromes
Improvement in the Health of Two Infants with Severe Disharmonious Overgrowth Syndromes
Disharmonious overgrowth syndromes are rare genetic diseases associated with a PIK3CA gene mutation. Since 2016, a team of researchers from Inserm, Paris Public Hospitals Group (AP-HP), Université de Paris, the Disharmonious Overgrowth and Vascular Abnormalities Unit of Institut Necker-Enfants Malades and the clinical departments of Hospices Civils of Lyon has demonstrated the therapeutic efficacy of alpelisib, a molecule used to fight certain cancers, in treating a group of children and adults with severe forms of these diseases.

Study of gene therapy treatment in Wiskott-Aldrich syndrome
Teams from the AP-HP, University of Paris, Inserm, within the Imagine Institute, the University College of London, and Généthon, have carried out work on treatment by gene therapy consisting of transplanting the patient's own genetically modified hematopoietic stem cells as part of a phase I/II clinical trial, promoted by Genethon, in 8 patients with Wiskott-Aldrich syndrome (WAS).

Cyclists and Pedestrians Inhale More Road Traffic Particles Than Motorized Transport Users
Cyclists and Pedestrians Inhale More Road Traffic Particles Than Motorized Transport Users
Users of different transport types breathe in over twice the dose of black carbon per 30-minute period when traveling compared with when not traveling (when at home or at work, for example). Unsplash The measurements of individual exposure to pollution, which are generally taken at the place of residence, overlook two major parameters: the much higher exposure occurring during travel and the variations in air volumes, and consequently the varying levels of air pollutants, which are inhaled according to the intensity of physical exertion involved by the journey.

Reducing air pollution: policies that pay off
Reducing air pollution: policies that pay off
Every year in France, fine particle pollution (particles with a diameter of less than 2.5 micrometres 1 ) leads to the premature death of around 40,000 people. The associated cost is estimated at €100 billion per year. Despite this, public policies to combat air pollution are generally implemented without first assessing their future health and economic impacts.

Identification of a novel therapeutic target in Multiple Myeloma
Identification of a novel therapeutic target in Multiple Myeloma
Multiple myeloma is a cancer of the bone marrow, with a life expectancy of less than 5 years post-diagnosis. Proteasome inhibitors, the therapeutic backbone of current treatments, are very effective in treating newly diagnosed cancers but resistance or intolerance to these molecules inevitably develop, leading to relapses.

Cannabis Use Since Adolescence Linked to Increased Unemployment Risk in Adulthood
Among the 17.1 million young Europeans who declared having used cannabis in the previous year, 10 million were between the ages of 15 and 24. Unsplash France has one of the world's highest levels of cannabis use, with around 40% of 17-year-olds reported to have used it in the previous year.

New, promising opportunities for treating skin fibrosis
New, promising opportunities for treating skin fibrosis
Skin fibrosis impairs skin tissue function, and has a strong aesthetic impact. French researchers have now shown that applying an electric field to the skin could cure skin fibrosis by reducing overly high collagen levels. Collagen, the main component of the skin's extracellular matrix, can cause a pathological condition if it is in excess.

A new therapeutic target to combat addiction?
A new therapeutic target to combat addiction?
Drug addiction is a psychiatric disorder for which no pharmacological treatment with long-term efficacy currently exists. All addictive substances share the property of raising concentrations of the neurotransmitter dopamine within brain regions forming the neural reward circuit. This increase in dopamine levels results in long-lasting alteration of signal transmission that is dependent on another neurotransmitter, glutamate, which causes addictive behaviours.

Breast cancers: ruptures in cell nuclei promotes tumor invasion
Breast cancers: ruptures in cell nuclei promotes tumor invasion
Cell nuclei protect the DNA. Nuclei can rupture when cells are deformed, causing DNA damage. In the case of breast cancer, this damage makes tumour cells more invasive, with increased risk of metastasis. When cells multiply and migrate, they can be compressed and their nucleus may break open. This phenomenon causes DNA damage.

COVID-19: Will telecommuting strategies stop the virus from circulating?
How can we best organise on-site workplace and school attendance periods and remote work to slow the circulation of Sars-CoV-2? Is it better to separate classes? Bring your whole team in at the same time? Set this up on daily or weekly schedules? The COVID-19 pandemic has forced most countries to impose contact limitations in workplaces, universities and schools.

Optogenetic Methods Restore Partial Vision in a Blind Patient
Optogenetic Methods Restore Partial Vision in a Blind Patient
Results of this research, a world-first, were published in  Nature Medicine on May 24th, 2021. An international research team has shown that optogenetic therapy has helped a patient with retinitis pigmentosa to partially regain visual function. This is a milestone step towards a type of gene therapy that could restore vision.
