"A small study showed preliminary evidence of activity in a peptide vaccine targeting KRAS mutations in pancreatic cancer.
Iโve written about an an mRNA-based pancreatic cancer vaccine that also targets KRAS, but this is a more traditional peptide vaccine, which can be used to target specific antigens on a cancer cell. ... There is a lot of research on vaccines being used to treat cancer, and pancreatic cancer, which is difficult to treat, is one of the top priorities.
Although this study was quite small, it has a remarkable success rate of preventing cancer in individuals who had a high success rate.
This can be an important tool in fighting pancreatic cancer, one of the more dangerous cancers."

The IBD pipeline is widening. Translation must keep up.
While conventional therapy still matters, with 5-ASA, corticosteroids and immunomodulators remain part of care, depending on disease phenotype and severity, for moderate-to-severe disease, targeted options now span:
๐น TNF blockade ๐น ฮฑ4ฮฒ7 blockade ๐น IL-12/23 and selective IL-23 inhibition ๐น JAK inhibition ๐น S1P modulation
Recently:
โข Tulisokibart: Merck reported positive topline Phase III induction-only results in UC. ATLAS-UC met its primary and key secondary endpoints at week 12. [1]
โข Duvakitug: Phase III programmes are underway in both UC and Crohnโs disease. [2]
โข Obefazimod: Abivax reported positive topline Phase III induction and maintenance results in UC. [3]
โข Icotrokinra: oral IL-23R inhibition is in Phase III for UC and a Phase 2b/3 programme for Crohnโs disease. [4]
Taken together, these programmes highlight at least four active development themes:
๐ธ TL1A blockade ๐ธ Oral targeted mechanisms ๐ธ Combination strategies ๐ธ Longer-acting antibody formats
More mechanisms do not automatically solve the translational problem.

T cell engagers (TCEs) are antibody-based, bispecific or multi-specific constructs that can reprogramme T cells to eliminate target cells expressing a defined surface antigen. Originally developed for cancer therapy, TCEs are now being investigated for the treatment of autoimmune diseases, with promising initial results. The interest in using TCEs for autoimmune diseases is rapidly growing given their comparable potency with cellular therapies, combined with the advantages of biologics, including ease of manufacturing, off-the-shelf availability, better safety and more convenient delivery. Here we review the history of TCEs, focus on distinct aspects of the mechanism of action of TCEs and explain design principles. We also discuss key challenges for future TCE development in autoimmunity, including enhanced safety, high convenience and complete target cell elimination. Finally, we provide an overview of the preclinical and clinical development landscape and give an outlook on next-generation TCEs that are optimized to treat a wide variety of autoimmune diseases. T cell engagers reprogramme T cells to eliminate pathogenic cell populations and are now emerging as a promising biologic strategy for autoimmune disease. This Perspective outlines their mechanisms, design principles and development challenges, highlighting next-generation approaches to improve safety, convenience and durable target cell depletion.

Anti-Rh immunoglobulins, such as Rhogam and similar brands, are not vaccines.
๐This warning may seem silly and outdated, but incredibly, many pregnant women at risk of Rh isoimmunization who have received anti-Rh immunoglobulin preparations (such as Rhogam) believe they are vaccines and will protect them in their current and future pregnancies, or that they simply won't need them because they will be sterilized.
๐Furthermore, they underestimate the importance of administering these preparations, and even worse, they lack access to them in hospitals and cannot afford to purchase them privately.
๐RHOGAM and similar brands do not contain any antigens, so they are not vaccines. Instead, they provide immediate passive immunity (antibodies), hence the confusion. They contain IgG immunoglobulins against the D+ antigen, which react against the erythrocytes of the fetus (Rh D+), destroying or inactivating their maternal macrophage and lymphocyte antigenic stimulation.
๐During pregnancy, after 10 weeks, small amounts of fetal blood can pass into the maternal bloodstream, potentially stimulating a maternal immune response (sensitization). This response can be more pronounced after 24 weeks of gestation and in pathological conditions (trauma, placenta previa, placenta accreta, etc.).
๐Finally, with anti-Rh immunoglobulins, perinatal complications of Rh isoimmunization, such as immune hydrops fetalis, its sequelae, as well as intrauterine and postnatal fetal death, are prevented.

Immunotherapy has changed the landscape of cancer treatment but the question remains: how can we make more patients benefit from durable responses?
A recent comment in Nature Cancer highlights an exciting area of research: ๐ญ๐๐ซ๐ญ๐ข๐๐ซ๐ฒ ๐ฅ๐ฒ๐ฆ๐ฉ๐ก๐จ๐ข๐ ๐ฌ๐ญ๐ซ๐ฎ๐๐ญ๐ฎ๐ซ๐๐ฌ (๐๐๐) ๐ข๐ง ๐ญ๐ฎ๐ฆ๐จ๐ซ๐ฌ.
TLS are organized immune structures that can develop within the tumor microenvironment. Increasing evidence suggests that their presence (especially mature TLS with germinal centers) is associated with improved prognosis and better responses to immune checkpoint inhibitors.
The next step is moving beyond TLS as biomarkers and exploring their potential as therapeutic targets. By inducing functional TLS, researchers hope to transform โimmune-excludedโ tumors into more immune-active environments and potentially enhance responses to immunotherapies.
Several strategies are already being explored, including approaches targeting lymphotoxin signaling, CD40 agonism, TLR9 activation, and combinations with existing immunotherapies.
The future of immuno-oncology may not only be about activating immune cells but also about creating the right immune environment where these cells can function effectively.

[#PARCC Highlight]: Retour sur une avancรฉe majeure en cardiologie : lโimmunothรฉrapie post-infarctus! On le sait dรฉsormais, les maladies cardiovasculaires comme lโathรฉrosclรฉrose ne sont pas de simples problรจmes de "tuyauterie", mais de vรฉritables maladies immuno-inflammatoires chroniques. Si cibler l'inflammation pour rรฉduire les risques de rรฉcidive est une piste validรฉe (notamment par l'essai CANTOS), les traitements actuels affaiblissent souvent les dรฉfenses immunitaires globales et augmentent le risque d'infection.
๐ฌ Une alternative prometteuse รฉmerge grรขce aux travaux de lโรฉquipe du #PARCC de Alain Tedgui, Ziad Mallat, Soraya Taleb et Hafid Ait-Oufella : stimuler nos propres cellules protectrices plutรดt que de bloquer le systรจme immunitaire. Leur cible ? Les lymphocytes T rรฉgulateurs (Treg) โ dont la dรฉcouverte majeure a d'ailleurs รฉtรฉ couronnรฉe par le prix Nobel de mรฉdecine en 2025. Ces cellules agissent comme les "modรฉrateurs" de notre systรจme immunitaire en calmant l'inflammation excessive.
๐ Les rรฉsultats spectaculaires de l'essai clinique IVORY (Phase II) : En administrant de l'interleukine-2 (IL-2) ร faible dose ร des patients ayant subi un syndrome coronaire aigu, l'รฉquipe a observรฉ : โก๏ธ +40 % d'augmentation du nombre de lymphocytes Treg par rapport au placebo. โก๏ธ Une rรฉduction significative de l'inflammation vasculaire (mesurรฉe par TEP-TDM), d'autant plus forte que l'inflammation initiale รฉtait รฉlevรฉe. โก๏ธ Zรฉro rรฉcidive dโรฉvรฉnement cardiovasculaire majeur dans le groupe traitรฉ aprรจs deux ans de suivi.
๐ก๏ธ Le double avantage de cette approche : ๐ Plus complรจte : Les Treg agissent par des mรฉcanismes multiples, s'attaquant ร l'hรฉtรฉrogรฉnรฉitรฉ de l'inflammation. ๐ Plus sรปre : Contrairement aux anti-inflammatoires classiques, l'IL-2 ร faible dose prรฉserve la compรฉtence immunitaire de l'organisme face aux infections.
๐ Prochaine รฉtape incontournable : lancer des essais de phase III ร grande รฉchelle pour confirmer ces donnรฉes et, on l'espรจre, transformer durablement la prise en charge post-infarctus.

Chimeric antigen receptor (CAR) T-cell therapy has revolutionized oncology, and its foundational logicโprecise antigen recognition coupled with durable effector activityโextends naturally to chronic non-malignant diseases sustained by long-lived pathological cells. These include viral reservoirs, autoreactive B and plasma cells, activated fibroblasts, alloimmune clones, and senescent cells that remodel tissue niches and evade clearance by conventional therapies.
This review highlights how CAR-based strategies can be adapted across diverse disease settings by redirecting engineered immune responses toward disease-sustaining cellular compartments. Co-stimulatory domains such as CD28, 4-1BB, and OX40 enhance persistence and effector function; programmed cell death protein 1 (PD-1)โCD28 switch receptors reverse inhibitory signaling; and cytokine-resistant CARs incorporating dominant-negative transforming growth factor-ฮฒ (TGF-ฮฒ) receptors maintain activity within suppressive microenvironments.
We discuss these approaches across infections, including human immunodeficiency virus (HIV) and EpsteinโBarr virus (EBV); autoimmunity involving CD19- and B-cell maturation antigen (BCMA)-directed depletion strategies and CAR-engineered regulatory T cells (CAR-Tregs); fibrosis targeting fibroblast activation protein (FAP); hemophilia using B-cell antibody receptor (BAR)-CARs against factor VIII and factor IX inhibitors; transplantation employing human leukocyte antigen (HLA)-specific CAR-Tregs; and senescence-associated pathologies targeting urokinase plasminogen activator receptor (uPAR) and natural killer group 2D ligands (NKG2DLs).
Early clinical experiences in systemic lupus erythematosus, systemic sclerosis, myositis, and multiple sclerosis, together with preclinical successes in chronic infections and fibrotic disease, demonstrate both feasibility and durable disease modification. By extending CAR-T therapy beyond oncology, these applications position programmable cellular immunotherapy as a broadly adaptable platform for eliminating persistent pathological cells, remodeling diseased tissue environments, and restoring long-term immune homeostasis.

The CAR-T therapy market is projected to grow from $5.76 billion in 2025 to $81.45 billion by 2035 - over 30% annual growth. The science works. Big Pharma is placing billion-dollar bets: Eli Lilly's $2.4B acquisition of Orna Therapeutics, AbbVie's $2.1B move for Capstan Therapeutics, BMS's $1.5B deal for Orbital Therapeutics - all in the last eighteen months.
So why do more than a third of industry leaders say they can't find the people to run any of it?
A shortage that isn't new, and isn't shrinking
This isn't a post-pandemic blip. BioPlan Associates has tracked hiring difficulty as a major constraint on biopharma manufacturing for over fifteen years, and the trend isn't improving: 36% of facilities can't fill process development roles, 28% struggle with downstream production, 27% lack sufficient process engineers.
Cytiva's 2025 Global Biopharma Index (1,250 leaders surveyed) sharpens the point: over a third of organisations report severe or critical shortages in cell and gene therapy specifically - clustered in process development, GMP manufacturing, quality, and regulatory affairs. Not the scientists who discover the therapy. The people who take it from lab to commercial scale.
Why it's structural, not cyclical
The industry keeps inventing job categories faster than anyone can train for them. Five years ago, "in vivo CAR-T" wasn't a hiring category. Every platform shift - in vivo delivery, allogeneic models, dual-antigen targeting - creates a new specialisation with no existing talent pool. Training pipelines can't keep pace with a two-year innovation cycle.
The result: a "barbell" labor market - simultaneous layoffs in some functions, fierce competition for specialists in others. Specialist searches now routinely take six to nine months, even at strong compensation.
Bench to Board, not just the bench
The scarcity that makes it hard to hire a GMP-experienced engineer also makes it hard to find a CMO who's actually taken a cell therapy through pivotal trials, or a regulatory lead fluent in ATMP approval pathways. Over 80% of biotech leaders expect workforce shortages to hurt their strategy over the next five years.
The $81 billion opportunity in CAR-T won't be limited by chemistry. It'll be limited by who's in the room to build it.

Iโve spent much of the past decade thinking about antibody-drug conjugates.ย The field has changed dramatically in that time: there are now 14 approved ADCs, including one (T-DXd) with tumor-agnostic, expression-based (HER2 3+) approval.
One constant theme I hear over and over is that target expression doesnโt predict response to ADCs.ย But Iโve always felt like that was an oversimplification of a complex problem. ย I loved reading this new Cancer Cell review from Pistilli et al., which clearly explained the nuances in detail.
They highlight that target expression correlates well with benefits for some ADCs but not others, and suggest payload class or therapeutic design may be responsible.ย For example, for TROP-2-targeting ADCs, internalization kinetics seem to matter as much or more than the more commonly scored membrane abundance.
They also highlight emerging work on therapeutic resistance mechanisms including TOP1 mutations, upregulation of efflux pumps, target loss, and impaired internalization (e.g., EGFR-HER2 heterodimerization suppressing T-DXd uptake) that can help identify why patients may stop responding.
The review expands on the traditional four-step mechanisms (target recognition and internalization -> trafficking -> linker cleavage -> payload release) to include bystander effect and immune mediated effects.ย This underscores why target expression is only one of many important factors.
Thereโs also review of indications where there hasnโt been strong ADC activity, such as ย pancreatic cancer.ย This could be due to a combination of antigen density, inefficient internalization, and stroma effects.ย Stroma modulating approaches are being explored here.ย
Itโs clear that matching the right ADC to the right patient will take more than a semi-quantitative IHC score.ย It will take a real understanding of how each individual therapeutic behaves in a given tumor environment.

Yesterday I shared our new Nature paper on HIV vaccine development. Our new paper is being discussed as an HIV vaccine advance, which is gratifying. It is also a study of how the immune system works. We think it will have long-lasting impacts in immunology.
When the idea of germline-targeting vaccines was first proposed, there wasnโt just skepticism about the vaccine design. There was skepticism about the underlying immunology. Many of the key steps were thought to be unlikelyโor even impossible.
Could extraordinarily rare naรฏve B cells be successfully recruited into an immune response?
Could those rare cells compete successfully inside germinal centers against millions of other B cells?
Could they undergo enough rounds of affinity maturation to evolve into broadly neutralizing antibodies?
Could memory B cells generated after one immunization be recalled months later by a different immunogen, re-enter germinal centers, and continue evolving?
Could this process be repeated over and over again?
These werenโt simply questions about HIV. They were fundamental questions about how B-cell memory, germinal centers, and antibody evolution actually work.
Our study shows that the answer to all of these questions can be yes.
Exceptionally rare precursor B cells can be primed, recruited into germinal centers, remain competitive through repeated rounds of affinity maturation, generate durable memory B-cell lineages, be recalled by sequential immunogens, and ultimately differentiate into plasma cells producing broadly neutralizing antibodies.
That is exciting because it advances HIV vaccine development. But it is equally exciting because it expands our understanding of adaptive immunity.
One of the most rewarding aspects of science is that pursuing one difficult problem often teaches us something much broader about biology than we originally set out to learn. I think this project is one of those examples.

Cancer immunotherapies have shown promise and success in a number of different types of tumours, yet many solid epithelial tumours remain recalcitrant. Somatic mutations in tumour cells can lead to the expression of neoantigens, which are potent targets of the human antitumour immune response. These can be targeted through adoptive cell transfer (ACT) of neoantigen-specific T cells, including tumour-infiltrating lymphocytes (TILs) or T cell receptor (TCR)-engineered T cells (TCR-T cells), an approach that has been shown to achieve tumour regression in patients with different types of metastatic solid tumours including melanoma, breast and gastrointestinal cancer. Immunogenomics, systems immunology and genome editing now provide multidisciplinary tools to design cell therapies against solid cancer. Here, we review historical efforts and our current conceptual understanding of ACT using TILs or TCR-T cells. Moreover, we highlight emerging correlates of response to ACT and novel strategies that integrate tumour immunology, cancer genomics, computational biology and T cell engineering for the development of next-generation cellular immunotherapies. In this Review, Krishna and colleagues draw on clinical and scientific progress in the past two decades to describe the many factors that influence clinical outcomes during adoptive cell therapy using tumour-infiltrating lymphocytes and TCR-engineered T cell therapies. They explain how T cell-intrinsic factors and tumour-specific factors in patients with advanced cancer challenge or promote the success of adoptive cell transfer (ACT), and outline new approaches in the field of ACT.

Immune checkpoint molecules are essential regulators of immune homeostasis, maintaining the balance between activation and tolerance. In cancer, tumours exploit checkpoint pathways to suppress antitumour immunity and promote progression. The advent of immune checkpoint inhibitors, particularly those that target the clinically validated PDL1โPD1 and CTLA4 axes, has transformed cancer therapy, and the LAG3 axis has recently entered clinical practice, yet most patients experience limited or transient benefit, often because the checkpoint molecules become dysregulated. Here, we examine how multilayered regulatory mechanisms operating at the genetic, epigenetic, transcriptional, post-transcriptional, translational and post-translational levels collectively shape checkpoint abundance and function in tumour and immune cells. We further connect these regulatory processes to immune evasion and therapeutic resistance and highlight how this knowledge informs biomarker development and mechanism-guided strategies to improve immunotherapy outcomes. Tumours evade immunity by dynamically rewiring immune checkpoint expression across multiple regulatory layers. In this Review, Eris, Zu et al. synthesize how these mechanisms operate in tumour and immune cells, connect them to therapeutic resistance, and highlight emerging biomarkers and therapeutic strategies that target convergent regulatory nodes to improve immunotherapy outcomes.

Here's the thing about flu vaccines โ they're usually injected into your arm. But that's not actually where the flu enters your body. It sneaks in through your nose, through the mucous tissue lining your airways.
So a team of researchers had an idea: what if we vaccinated people right at the entry point? Coat the gums where they meet the teeth: a thin, leaky strip of tissue that connects directly to the immune system and deliver the vaccine there instead.
Genius. Except one problem.
How do you get a vaccine precisely into a tiny pocket below the gumline?
And then someone looked at the table and saw a keychain.
The breakthrough moment in this research was a researcher spotting a keyring lying around the lab after a failed experiment, and thinking what if I use this to hold the mouse's jaw open gently?
Vaccinated mice survived flu infections. Their immune systems learned to fight the virus โ no needle required. And one version of the floss vaccine performed just as well as a nasal spray vaccine, without the risk of neurological side effects that nasal vaccines sometimes carry.

In 2003, the worldโs first synthetic mRNA injections in humans were carried out in Tรผbingen, Germany. Many people โforgetโ to mention this in their timelines on mRNA vaccines. So let me remind it (and please eventually correct your timelines in articles and talks): First mRNA injections in humans (in me): 2003, published in 2007 First clinical trial on mRNA vaccines: started in 2003 and published in 2008 Second clinical trial on mRNA vaccines: launched in 2004, published in 2009 Third clinical study on mRNA vaccines: launched in 2004, published in 2011. All these studies were conducted at Tรผbingen University Hospital by Dr Weide, Dr Brossart, myself and numerous colleagues from the University of Tรผbingen, Tรผbingen University Hospital and CureVac. All those pioneering mRNA vaccine studies showed safety and immune responses.

The therapy is priced at RMB 19,800 per infusion, roughly US$2,700โ2,900. A full eight-dose course costs around US$22,000โ23,000.
Now, PLA General Hospital, widely known as 301 Hospital and one of Chinaโs most influential national medical centers, is studying the same product in aging and vascular-aging cohorts.
The studies focus on measurable aging-related endpoints, including biological age, multi-omics markers, and vascular stiffness. Results are still pending.
