Influenza: A New Avenue for Developing Innovative Treatments
Seasonal influenza is a major public health issue because it continues to remain associated with considerable mortality, particularly among people who are elderly, immunocompromised, or both. It also has a significant socioeconomic cost. With vaccination and current treatments still being of limited efficacy, research teams are trying to develop new therapeutic approaches.

Infertility: New Avenues to Understand the Harmful Effects of Chemotherapy
Infertility is a public health problem affecting millions of couples in France. Among the possible causes, chemotherapy has been singled out as having particularly harmful effects on the fertility of both women and men. In order to better prevent and restore fertility in cancer survivors, understanding the mechanisms behind these negative effects is a priority.

HIV: The Antibodies of ’Post-treatment Controllers’
A very small percentage of people with HIV-1, known as "post-treatment controllers” (PTCs), are able to control their infection after interrupting all antiretroviral therapy. Understanding the fundamental mechanisms that govern their immune response is essential in order to develop HIV-1 vaccines, novel therapeutic strategies to achieve remission, or both.

COVID-19: ’Reactive’ Vaccination, Effective in Case of High Viral Circulation?
Although the majority of its population is fully vaccinated, the virus continues to actively circulate in France. As health restrictions are being lifted, fears of a resurgence of the epidemic and of the emergence of new more contagious variants are leading scientists to consider new strategies to continue to promote vaccination among populations that remain hesitant.

MICA: A New Immune Response Gene That Predicts Kidney Transplant Failure
Although a kidney transplant is the only curative treatment for end-stage kidney disease, the risk of the patient's body rejecting the graft means that success is not guaranteed. To reduce this risk, physicians are now able to look at a certain number of genetic and immunological parameters in order to evaluate the histocompatibility between donor and recipient - i.e. how compatible their organs and tissues are.

Covid-19 - Towards a vaccination strategy adapted to immunosuppressed patients
Publication of the CIRI in the journal Science Translational Medicine on February 1 st , 2022. Claude Bernard Lyon 1 University focus on February 24, 2022. Transplant recipients, who receive therapeutic immunosuppression to prevent graft rejection, are characterized by high coronavirus disease 2019 (COVID-19)-related mortality and defective response to vaccines.

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
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.

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
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.

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?
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.

Deciphering the energetic code of cells for better anticancer therapies

Epigenetic treatments: New allies for chemotherapies?
If genetics is interested in gene sequencing, epigenetics studies how genes are going to be used, or not used, by a cell. The epigenome of a cell represents the set of chemical modifications of the DNA or associated proteins that will determine the expression of the genes and thus the cell's identity.

Increased Ischemic Stroke Risk Associated with Certain Medications for Nausea and Vomiting
Every year in France, 140,000 people have a stroke 1 . Around 80% are ischemic strokes or cerebral infarctions, which occur when a brain artery is obstructed by a blood clot. Studies have shown that the risk of ischemic stroke is increased by the use of antipsychotics: medications with antidopaminergic 2 properties that are commonly prescribed in psychiatry.

Chatbot for addressing COVID-19 vaccine hesitancy
A considerable fraction of the population is reluctant to get vaccinated against COVID-19. French scientists have designed a chatbot that offers personalised responses to questions posed by the curious or hesitant-and have demonstrated its effectiveness. What if a few minutes of interaction with a chatbot could effectively address vaccine concerns? In an article published in the Journal of Experimental Psychology: Applied (28 October 2021), researchers from the CNRS, INSERM, and ENS-PSL show that such an interface is indeed capable of swaying the vaccine-hesitant.

Six new research projects concerning Covid-19
On April 10, 2020, ANR announced the funding of 86 projects concerning Covid-19. Six are associated with ENS de Lyon laboratories. The SARS-CoV-2 infection is a global emergency for human health. The interferon response is the body's first barrier to defending viral infections. This host response is initiated by the recognition of viral elements by receptor and leads to the production of molecules, including interferon, that alert surrounding cells.
