Asthme : prévention, vaccination⊠et entretien pharmaceutique
On parle souvent des risques infectieux chez les patients asthmatiques â grippe, pneumocoque â et de lâimportance de la vaccination pour Ă©viter des exacerbations sĂ©vĂšres.
Mais un levier reste encore sous-exploitĂ© : lâentretien asthme. đ Un moment clĂ© pour Ă©valuer le contrĂŽle de la maladie đ Un espace pour vĂ©rifier lâobservance et la bonne utilisation des dispositifs đ Une opportunitĂ© pour sensibiliser Ă la prĂ©vention, notamment vaccinale đ Un point de contact rĂ©gulier dans le parcours de soins
Câest un dispositif puissant⊠à condition quâil soit rĂ©ellement activĂ©. Aujourdâhui, le dĂ©fi nâest plus seulement dâinformer, mais de structurer et de systĂ©matiser ces interactions.
Câest lĂ que la technologie peut faire la diffĂ©rence.
Chez Apodis, nous travaillons Ă : âïž Identifier les patients Ă©ligibles Ă lâentretien asthme âïž Aider les pharmaciens Ă structurer leurs interventions âïž IntĂ©grer la prĂ©vention vaccinale dans chaque Ă©change âïž Suivre lâimpact dans le temps
Lâentretien asthme ne doit plus ĂȘtre une opportunitĂ© ponctuelle, mais un vĂ©ritable outil de pilotage du parcours patient.
Et si chaque passage en pharmacie devenait un point dâactivation de la prĂ©vention ?

đđŽđČđ» đđŒđ»đČđ đđŒ đđŒđșđșđźđ»đ± đđđ»đŽ đđČđłđČđ»đđČ | University of Basel researchers led by Jean de Lima found that specialized helper T cells migrate to oxygen-scarce edges of immune hubs during lung infection. There, they produce the so-called HIF-1α protein and release interleukin-21, directing macrophages, B cells, and natural killer cells into coordinated responses against respiratory pathogens. Using advanced imaging in influenza-infected mice and inducible knockout models, the team mapped how these cells position at hub boundaries to orchestrate defense networks.
The findings show tissue-resident immune hubs function as command centers for on-site protection rather than antibody factories. Professor Carolyn King's group validated the mechanism across secondary influenza infections and lung cancer models, showing broad therapeutic potential. This breakthrough enables design of inhalable vaccines that build immune defense directly in airways where viruses enter, potentially transforming respiratory disease prevention. The spatial coordination strategy also opens perspectives for tissue-targeted therapies that use the body's natural positioning systems to strengthen local immune responses at infection sites.

Pre-eclampsia is often described as a disease of the placenta, but at its core it is also a disease of immune balance. When the maternal immune system becomes overactivated, the delicate vascular architecture of the placenta can begin to fail.
Recent data showing rising pre-eclampsia rates after the pandemic has prompted renewed interest in immune-vascular triggers. If spike protein interacts with macrophages and endothelial cells in the placenta, understanding that mechanism could become a crucial piece of the puzzle in protecting maternal and fetal health.

Oral Vaccines Are Moving From Research to Reality
The global vaccine landscape may be entering a new phase â and oral vaccines are quickly becoming one of the most discussed innovations in infectious disease prevention. In recent industry conversations across biotech and pharmaceutical research communities in the U.S., more attention is shifting toward oral vaccine platforms. Unlike traditional injections, oral vaccines could simplify distribution, improve patient compliance, and make large-scale immunization campaigns far more accessible â especially in regions where healthcare infrastructure is limited. Several biotechnology companies are now accelerating research around oral delivery systems, mucosal immunity, and next-generation vaccine platforms. The idea is not only to prevent disease more effectively, but also to rethink how vaccines are manufactured, distributed, and administered globally. For pharmaceutical companies and healthcare systems, this shift could represent more than just a scientific breakthrough. It may reshape public health logistics, vaccine accessibility, and global pandemic preparedness in the coming decade. The question many people in the industry are asking now is: If oral vaccines become widely scalable, could they fundamentally change the way the world approaches infectious disease prevention? Curious to hear perspectives from people working across biotech, healthcare, and public health.

A very insightful review from the Akiko Iwasaki's group on the potential to harness mucosal immunity in next-generation vaccine development. While the rapid deployment of intramuscular mRNA vaccines was a landmark achievement in preventing severe COVID-19, intramuscular shots often fall short of providing sterilizing immunity. Mucosal immunity represents a particularly promising avenue for improving vaccines against respiratory viruses, as it enables immune protection to be established directly at the site of viral entry and early replication. Mucosal tissues, such as the respiratory tract, host locally regulated specialized immune cells that are functionally and spatially distinct. Reduction of infection and transmission requires engaging the mucosal immune response: a coordinated process beginning with epithelial pathogen sensing and culminating in the establishment of tissue-resident memory T (TRM) and B (BRM) cells, alongside robust local secretory IgA (SIgA) production. Unlike systemic IgG, nasal SIgA has demonstrated superior virus-neutralizing activity and greater breadth against antigenically drifted variants. A promising strategy for advancing vaccine design is the heterologous prime-boost approach. Research suggests that intramuscular priming (to establish peripheral memory pools) followed by an intranasal boost can effectively "pull" memory cells to the respiratory mucosa. However, the so-called 'mucosal' vaccines requires navigating complex physiological constraints, such as the mucociliary clearance system and the anionic mucus layer. Moreover, the regulatory path for mucosal vaccines is primarily hindered by the lack of validated correlates of protection, making it difficult to predict efficacy and guide clinical trial designs. Additionally, the anatomical proximity of the nasal mucosa to the central nervous system necessitates rigorous safety evaluations to prevent neuro-olfactory spillover or unintended neuro-inflammation. https://lnkd.in/eb5ZUMY4

Nasal spray vaccine could âreplace multiple jabs every yearâBookmark popoverRemoved from bookmarksClose popoverScientists at Stanford Medicine have developed a universal vaccine formula, tested on mice, that offers broad protection against various respiratory threats. The vaccine, delivered as a nasal spray, could protect against cold, flu, Covid, allergies, respiratory viruses, sepsis-causing bacteria, and even house dust mites. It works by mimicking the signals immune cells use to communicate during an infection, rather than targeting specific parts of a pathogen. If developed for humans, this vaccine could replace multiple annual jabs for winter respiratory infections and potentially protect against new pandemic bugs. While lead author Dr Bali Pulendran estimates human availability within five to seven years, other experts caution that a truly universal vaccine is still some way off due to safety considerations and the diversity of the human population.

Ever had a client ask: "Why does my kitten need to come TWO times for vaccines? Can't we just do it all at once?"
Let me break down the science in a way that might change how it act
đ§Ź The "Goldilocks Problem" of Maternal Immunity Kittens are born with almost NO immunity from their mother during pregnancy. Unlike humans, cats have a special type of placenta that blocks antibody transfer before birth. Instead, 90-95% of protective antibodies come through colostrum in those critical first 16 hours of life (Claus et al., 2006).Âč
But here's where it gets tricky... These maternal antibodies are both a blessing and a curse: â
They protect vulnerable kittens from deadly diseases â But they ALSO attack vaccine antigens, preventing the kitten from building their own immunity
This creates what scientists call the "window of susceptibility", a period where kittens are: -Too vulnerable to fight off real infections -Yet unable to respond to vaccines
Consider these exposure risks for "indoor-only" cats: -Panleukopenia virus survives for YEARS in the environment and can be tracked indoors on shoes and clothing -Multi-cat households where ONE cat goes outside creates risk for ALL cats
Here's what evidence-based feline vaccination looks like in #2026: For Kittens: â Start at 6-8 weeks, continue every 2-4 weeks until 16-20 weeks â Core vaccines: FPV, FHV-1, FCV â FeLV for ALL kittens (remember that age-resistance curve!) â Rabies at 12-16 weeks â yearly booster For Adult High-Risk Cats: â Annual booster of Core and Rabies
What challenges do you face while Vaccination?

Can a woman with an optimal vaginal microbe donate and thereby resolve molecular vaginal dysbiosis in another woman???
We wanted to answer the question in this first randomised controlled trial - It was one of the studies in Tine WrĂžnding PhD - she organised more than 900 clinical visits to make this possible and it has been a remarkable team effort - huge thanks to everybody involvedđȘđ
Although some women experienced donor microbiome engraftment - especially after pre-treatment - and although we learned a lot about the vaginal microbiome - this is a negative trial - going forward we need to explore who will benefit vaginal microbiome transplantation or find alternative ways to treat vaginal dysbiosis đŹ

Most pathogens donât wait for an invitation, they enter through our mucosal surfaces.
A recent paper in Nature Reviews Immunology highlights a critical gap in how we think about vaccines: while traditional injected vaccines are excellent at preventing severe disease, they often fall short at the bodyâs frontlines; the respiratory, gastrointestinal, and urogenital mucosa.
đŹ Key takeaway: To truly control infections (and not just reduce symptoms), we need to design vaccines that generate strong mucosal immunity.
Hereâs why this matters:
âą Mucosal tissues are the first point of contact for most pathogens âą Local immune defenses (like IgA and tissue-resident memory cells) can stop infections before they start âą Current systemic vaccines donât always induce strong protection at these sites âą Mucosal vaccines (e.g., nasal or oral) could help block transmission, not just disease
đĄ The future of vaccination may lie in integrated strategies: Systemic priming + mucosal boosting = broader, more effective protection
This shift is especially relevant for respiratory and emerging zoonotic diseases, where stopping transmission is just as important as treating illness.
As we continue to rethink vaccine design, one thing is clear; the protection at the entry point could change the game.

đ«Â Uncovering the Lungâs Local Immune Network
When a virus enters the lungs, the immune system must respond immediately. The King lab, Jean de Lima as first author, at the Department of Biomedicine and the UniversitĂ€t Basel has now identified a specialized group of CD4âș T cells that coordinate a local immune defense directly within the lung.
These T cells produce a molecule called HIF-1α, which is typically known as a cellular stress sensor but can also be activated by immune signals. Using advanced imaging methods, the team mapped how these cells position themselves at the outer edges of small immune hubs and release interleukin-21 (IL-21) to activate neighboring cells. When HIF-1α was switched off in the T cells, the local immune network collapsed, leaving the lungs poorly equipped to fight off a second infection with a different influenza strain.
The same HIF-1α-driven T cells were also found in a mouse model of lung cancer, where they supported the immune systemâs fight against tumor cells. This suggests that the lung maintains its own immune ecosystem â a coordinated community of cells with distinct roles in tissue defense.Â
This discovery provides important insight for developing inhalable mucosal vaccines that protect the lungs where viruses first enter, and it may also inform new strategies for tissue-targeted immunotherapies.
Congrats to this great achievement!

đ§Ź Programming lung immunity through mucosal vaccination
A new Science Magazine study shows how intranasal vaccination can induce broad protection against diverse respiratory threats in mice.
Using an intranasal liposomal formulation combining TLR4 and TLR7/8 agonists with antigen, the authors demonstrate durable protection against multiple viral and bacterial respiratory infections, as well as allergic airway inflammation.
Multi-omic profiling of lung tissue reveals several key features of this response:
đč Durable tissue-resident T cell immunity Intranasal vaccination induces persistent antigen-specific CD4âș and CD8âș tissue-resident memory T cells (TRM) in the lung that remain detectable for months.
đč Epigenetic reprogramming of alveolar macrophages Single-cell transcriptomic and chromatin accessibility analyses reveal sustained transcriptional and epigenomic remodeling of alveolar macrophages, enhancing antigen presentation, phagocytosis, and antiviral responses.
đč T cellâinnate cell cross-talk via RANKL signaling Memory T cells imprint macrophage function through RANKL-mediated signaling, establishing a feed-forward circuit between adaptive and innate immunity within lung tissue.
đč Rapid spatial immune organization upon infection Following challenge, vaccinated lungs rapidly form tertiary lymphoid structures, enabling accelerated pathogen-specific T- and B-cell responses.
These findings support the concept of âintegrated organ immunityâ - a coordinated network of tissue-resident immune and structural cells that can provide broad protection against diverse respiratory threats.
đĄ The study also highlights how integrating spatial transcriptomics, single-cell RNA-seq, and chromatin accessibility profiling enables detailed mapping of immune programming directly within lung tissue microenvironments.

Glycans are essential components of homeostatic networks, acting as fine tuners of immunological responses, and are therefore promising targets for manipulating immune tolerance. Glycans shield the entire gut mucosa surface, contributing to epithelial barrier integrity. Moreover, most microorganisms expose glycoconjugates on their surfaces, making glycans essential molecules in the crosstalk between host immune response and the gut microbiota. The vast amount of biological information encoded by mucosal glycans is deciphered by a variety of glycan-binding proteins that translate glycan recognition into either pro-inflammatory or anti-inflammatory responses. Current evidence from inflammatory bowel disease (IBD) has highlighted the prominent role of glycans in establishing and regulating key cellular and molecular pathways underlying the transition from health to intestinal inflammation, with implications for understanding IBD immunopathogenesis and for IBD prediction and prevention. In this Review, we discuss current advances, emerging challenges and future prospects in exploiting the power of the mucosal glycocalyx and the glycome as master coordinators of the immunoregulatory networks in IBD from the preclinical phase to established diagnosis. We discuss the clinical utility of the glycome as a serological biomarker with diagnostic, prognostic and predictive value, and as a potential new target for preventive intervention strategies in IBD. Glycans are essential components of the gut mucosa that modulate epithelial barrier integrity, hostâmicrobiota interactions and gut immune response. This Review discusses the role of mucosal glycans in gut homeostasis, in intestinal inflammation and their therapeutic potential for inflammatory bowel disease.

What does it mean if we find measles virus in a SEWER? Iâm a few weeks into my new role as Vermontâs State Epidemiologist for Infectious Diseases and last week we detected measles virus in wastewater in the state, even though our team hadnât found any cases of measles since last spring.
Measles virus isnât usually in wastewater, so finding it there means that someone had measles in the area. They might have been a resident or someone traveling through (and who wouldnât want to travel through Vermont??).
Fortunately, our epidemiology team has many âstreamsâ of data (get it?). So, a few days later, we were able to identify a case of measles in a person living in the same area. Our epidemiologists connected with the patient to help prevent further spread.
We now know that wastewater is working for us as an early detection system. With rising measles throughout the United States, we will be keeping a close eye on it.
