Life-Changing Miracle for Baby with Fatal Disease ๐Ÿ‘‡

Eisa Hussain, a four-year-old boy born with the severe form of leukocyte adhesion deficiency 1 (LAD-1), was given a "death sentence" without treatment.

This ultra rare disease cripples the immune system, often leading to death before age two.

๐Ÿ‘‰ This innovative gene therapy, developed by Rocket Pharmaceuticals, used Eisaโ€™s own stem cells at GOSH to replace the faulty gene responsible for the condition, restoring his immune system.

Now, several months after receiving the treatment, Eisa is thriving, playing football, attending school, and living a normal life something his family once thought impossible.

This incredible breakthrough is a beacon of hope for other families facing rare, life-threatening conditions.

Amazing to see just how powerful gene therapy is in saving lives ๐Ÿ‘

A malaria vaccine showing up to 90% protection in early clinical studies and a key question: how does it work? Thatโ€™s what the European CAPTIVATE consortium is working on. BPRC is a partner.

https://lnkd.in/ekNSR4Jw

In Antwerp, researchers from across Europe came together to share progress and align next steps.

The CAPTIVATE consortium approach is fundamentally different. Instead of using fragments of the parasite, this vaccine uses a genetically attenuated version of the malaria parasite itself.

After vaccination, the parasite reaches the liver, but stops there. It cannot develop further. This allows the immune system to recognise and eliminate the parasite at the earliest stage, before it causes disease.

โ€œThe strong protection seen in healthy volunteers often doesnโ€™t translate to endemic settingsโ€, says Erica Pasini (BPRC). โ€œWe want to understand why and how to make it work where it matters most.โ€

At BPRC, we contribute by studying immune responses in greater depth, helping to bridge the gap between controlled studies and real-world impact. Duringย the meeting, scientists shared the latest developments. Key project milestones have already been reached, and the work is in full swing!

Next step: in June, the first results of the non-human primate trial will become available along with key samples to further investigate the immune mechanisms behind protection.

Things to Do and Not to Do When Vaccinating Birds ๐Ÿ“๐Ÿ’‰


โœ… Things to Do When Vaccinating Birds
Use healthy birds only โ€“ Vaccinate only birds that are active and disease-free.Only vaccinate healthy birds; postpone vaccination if the flock is showing signs of illness.
Follow vaccination schedule โ€“ Give vaccines at the correct age and time.
Maintain cold chain (2โ€“8ยฐC) โ€“ Keep vaccines in a refrigerator or ice pack.Bring them out of the cooler only when ready to use.
Use clean water for vaccines โ€“ Especially for drinking-water vaccines.
Use sterile equipment โ€“ Clean syringes and droppers should be used.
Read manufacturerโ€™s instructions โ€“ Follow dosage and method carefully.
Vaccinate early in the morning or evening โ€“ Avoid heat stress.
Withhold water for 1-4 hours before vaccination to ensure birds are thirsty.
Mix vaccine properly โ€“ Ensure even distribution in water or solution.
Consider adding skim milk powder (about 2g per liter) to stabilize the vaccine.
Ensure the vaccine is consumed within 1-2 hours.
Record vaccination details โ€“ Date, vaccine name, age of birds, batch number.
Walk through the house to encourage birds to move around and drink or if in Battery cage system, ensure the nipples are not blocked.
Observe birds after vaccination โ€“ Monitor for reactions or stress.

โŒ Things Not to Do When Vaccinating Birds
Do not vaccinate sick birds โ€“ It may worsen their condition.
Do not use expired vaccines โ€“ They will not work effectively.
Do not expose vaccines to sunlight or heat โ€“ This destroys the vaccine.
Do not mix vaccines with dirty water โ€“ It reduces effectiveness.
Do not use antibiotics before or after vaccination โ€“ May affect vaccine response.
Do not overcrowd birds during vaccination โ€“ Causes stress.
Do not open vaccine long before use โ€“ Use immediately after opening.
Do not use chlorinated water โ€“ Chlorine kills live vaccines.
Do not skip booster doses โ€“ Immunity will be weak.
Do not vaccinate during extreme weather โ€“ Heat or cold affects immunity.

Vaccines and Immunology: A Foundation of Preventive Medicine

One of the most impactful applications of immunology is vaccinationโ€”a concept built on a simple yet powerful idea: training the immune system before exposure to disease.

The adaptive immune systemโ€™s ability to developย long-term memoryย allows vaccines to provide lasting protection with minimal risk. This principle has transformed global health outcomes and continues to shape modern medical innovation.

Whatโ€™s particularly remarkable is how advancements in biotechnologyโ€”especially mRNA platformsโ€”have accelerated vaccine development timelines without compromising safety or efficacy.

Vaccination is not only an individual health decision; it is aย collective responsibilityย that strengthens public health systems through herd immunity.
As science continues to evolve, the role of immunology in preventive medicine will only become more critical.

The future of healthcare is not just about treating diseaseโ€”but preventing it.

From Lab to Production Line: Key Aspects of Bioreactors in Vaccine Applications | Shizhou Liu

From Lab to Production Line: Key Aspects of Bioreactors in Vaccine Applications | Shizhou Liu | Immunology and Biotherapies | Scoop.it
The most critical strategy for controlling the spread of infectious diseases is vaccinationโ€”making vaccine production processes pivotal to disease control and eventual eradication. Vaccination is an artificial process where inactivated, attenuated infectious pathogens, or their components, are delivered to the human body, using antigenic structures to activate the immune system. This process stimulates an effective response against specific pathogens to combat impending infections.

Since the mid-20th century, viral vaccines have been produced using chicken embryos, with dozens of approved traditional human vaccines manufactured via embryo-based processes. Today, however, cell culture-based vaccine production has become widespread: it enables simple infection and replication in controlled environments, with harvesting steps conducted in closed bioreactor systems to ensure sterility and further reduce biosafety risks through automation. This approach significantly boosts factory capacity, enabling the production of large quantities of vaccine doses.

Sanofi Publishes In Vivo CAR-T Data | Cesare Di Nitto posted on the topic

Sanofi Publishes In Vivo CAR-T Data | Cesare Di Nitto posted on the topic | Immunology and Biotherapies | Scoop.it
Sanofi just published their in vivo CAR-T data.

The paper will be published in ๐˜”๐˜ฐ๐˜ญ๐˜ฆ๐˜ค๐˜ถ๐˜ญ๐˜ข๐˜ณ ๐˜›๐˜ฉ๐˜ฆ๐˜ณ๐˜ข๐˜ฑ๐˜บ this month.

Was this built in-house? Not really. It's the result of two strategic acquisitions that tell you exactly how big pharma is entering in vivo cell engineering.

Everything started about 8 years ago with Sanofi entering the mRNA therapeutics space first.

In 2018, Sanofi partnered with Translate Bio for mRNA vaccines. $45M upfront. Focusing specifically on up to five infectious diseases.

COVID hit.

They expanded the deal in 2020 to $300M cash + $125M as stock investment, covering all infectious diseases.
Then in August 2021, they acquired the whole company for $3.2B!!!

What did they get? One of the largest private LNP libraries in the industry. mRNA manufacturing expertise. A platform ready to go beyond vaccines.

๐˜‰๐˜ถ๐˜ต ๐˜ฎ๐˜™๐˜•๐˜ˆ ๐˜ต๐˜ฆ๐˜ค๐˜ฉ ๐˜ข๐˜ญ๐˜ฐ๐˜ฏ๐˜ฆ ๐˜ฅ๐˜ฐ๐˜ฆ๐˜ด๐˜ฏ'๐˜ต ๐˜ฎ๐˜ข๐˜ฌ๐˜ฆ ๐˜ช๐˜ฏ ๐˜ท๐˜ช๐˜ท๐˜ฐ ๐˜Š๐˜ˆ๐˜™-๐˜› ๐˜ธ๐˜ฐ๐˜ณ๐˜ฌ!

Three months before closing Translate Bio, Sanofi acquired Tidal Therapeutics in April 2021. $160M upfront, $470M total including milestones.

๐—ฆ๐—ฎ๐—ป๐—ผ๐—ณ๐—ถ'๐˜€ ๐˜๐—ผ๐˜๐—ฎ๐—น ๐—ฐ๐—ผ๐—บ๐—บ๐—ถ๐˜๐—บ๐—ฒ๐—ป๐˜:
+$๐Ÿฏ.๐Ÿฒ๐—• ๐˜๐—ผ ๐—ฒ๐—ป๐˜๐—ฒ๐—ฟ ๐˜๐—ต๐—ฒ ๐—บ๐—ฅ๐—ก๐—” ๐—ฎ๐—ป๐—ฑ ๐—ถ๐—ป ๐˜ƒ๐—ถ๐˜ƒ๐—ผ ๐—–๐—”๐—ฅ-๐—ง ๐˜€๐—ฝ๐—ฎ๐—ฐ๐—ฒ

Tidal brought the missing piece: targeted nanoparticle technology to reprogram immune cells directly in the body.

Now the paper shows what happens when you combine both platforms.

The technical execution is solid:

โ€ข Proprietary ionizable lipid 15 for T cell transfection
โ€ข Anti-CD8 VHH nanobody outperforming other ligands
โ€ข CD22 CAR benchmarked against clinically validated CARs (FMC63 and m971)
โ€ข Hepatic de-targeting, under 5% liver uptake
โ€ข Tumor suppression in aggressive human models

That last point matters. Getting mRNA into T cells is hard enough.

Keeping it away from liver trapping while maintaining efficacy is the real challenge.

They solved both.

This is how platforms get built in 2025. You don't develop everything internally. You acquire the best technology, integrate it fast, and publish validation data within a few years.

Translate Bio gave them the mRNA engine. Tidal gave them the targeting system. Together, they created an in vivo CAR-T platform neither could build alone.

The question now is whether improvements we witness in the in vivo CAR-T space will scale beyond hematological malignancies.

The delivery is transient.
The safety profile looks clean (mRNA).
Serial killing durability up to 8 days.
And repeat dosing gave no signs of toxicity.

Can this match the persistence of ex vivo products?
Will in vivo CAR-T platforms ever be efficacious in solid tumors?

So much money has been invested in this tech and we are seeing progress with creative solutions to optimize in vivo CAR-T platforms.

Interesting in Cell Stem Cell: In vivoย CAR-Tfh cell reprogramming restores tolerance in a mouse model of autoimmune hepatitis
https://lnkd.in/en36DGSU
Autoimmune diseases involve the coordinated dysregulation of multiple types of immune cells, and single-cell targeted therapies often yield suboptimal results. Here, we developed chimeric antigen receptor (CAR)-engineered follicular helper T (Tfh) cells capable of simultaneously suppressing T cells, B cells, and dendritic cells (DCs) to restore immune homeostasis in an autoimmune hepatitis (AIH) mouse model. Using amino acid-derived lipid nanoparticles, we deliver self-amplifying RNA encoding Forkhead box protein P3 (Foxp3) and a cytochrome P4502D6 (CYP2D6)-specific CAR to Tfh cells, conferring stable regulatory features and antigen-dependent suppressive activity. Engineered CAR-Tfh cells preferentially localize to the liver, recognize CYP2D6-expressing hepatocytes, and suppress pathogenic T cell and B cell responses. In AIH-II mouse models, CAR-Tfh cell generation restores a tolerogenic hepatic immune environment and ameliorates autoimmune liver injury. These findings establishย in situย Tfh cell reprogramming as a modular approach to coordinately modulate multiple immune compartments, providing a potential therapeutic framework for AIH and related autoimmune diseases.

Turning mosquitoes into "flying vaccines"? Science is getting creative in the fight against infectious diseases.

A fascinating new line of research explores how mosquitoes could be used to deliver vaccines to wild bats-helping stop dangerous viruses like rabies and Nipah at their source before they spill over into humans.

Here's the idea:

Mosquitoes are engineered to carry a harmless vaccine virus

When they bite bats, they "inject" immunity

Alternative approach: mineral-rich drinking stations with edible vaccines

Why this matters:

Bats are natural reservoirs for many high-risk viruses, and traditional vaccination methods simply don't work at scale in wild populations. Instead of culling (which can backfire), scientists are looking at ecological, non-invasive solutions.

Early results are promising:

Vaccinated animals developed protective antibodies

Bats were successfully immunized via bites,
ingestion, and drinking

Some survived otherwise lethal virus exposure

Of course, big questions remain-especially around environmental safety, regulation, and real-world deployment.

But this approach signals something bigger:
A shift toward stopping pandemics at the source, not just reacting to them.
Innovations like this could redefine how we manage zoonotic diseases in an increasingly interconnected world.

๐Ÿ„ Understanding Vaccination & Antibody Titre Dynamics in Dairy Cattle ๐Ÿงฌ

Effective vaccination is not just about injecting vaccinesโ€”itโ€™s about understanding how the immune system responds and how long protection lasts.

๐Ÿ”ฌ What happens after vaccination?
The animalโ€™s immune system produces antibodies. The first response is slow and low, while booster doses create a faster and stronger immunity.

๐Ÿ“Š Antibody Titre Dynamics:
Antibody levels follow a pattern:
โžก๏ธ Lag Phase โ†’ ๐Ÿ“ˆ Peak โ†’ ๐Ÿ“‰ Decline

This is why timely booster doses are essential to maintain protection.

๐Ÿฎ Maternal Antibodies in Calves:

- Obtained through colostrum
- Provide early protection
- Can interfere with early vaccination

โณ Proper timing of vaccination in calves is critical to avoid vaccine failure.

๐Ÿ“… Practical Vaccination Strategy:

- Calves: 3โ€“6 months
- Boosters: 2โ€“4 weeks after first dose
- Adults: Annual or biannual vaccination

โš ๏ธ Factors Affecting Immune Response:

- Nutrition (Protein, Zinc, Selenium)
- Stress & disease conditions
- Proper vaccine storage & handling (cold chain)

๐Ÿงช Why Antibody Titre Testing Matters?

- Evaluate vaccine effectiveness
- Monitor herd immunity
- Optimize vaccination programs
(Common method: ELISA)

๐Ÿ’ก Key Takeaways:
โœ” Boosters are critical
โœ” Good nutrition improves immunity
โœ” Monitor and adapt vaccination plans

๐ŸŒฑ Strong immunity = Healthy herd = Better productivity

Type I interferon restricts mRNA vaccine efficacy through suppression of antigen uptake in cDCs - npj Vaccines | Miroslav Gasparek

Type I interferon restricts mRNA vaccine efficacy through suppression of antigen uptake in cDCs - npj Vaccines | Miroslav Gasparek | Immunology and Biotherapies | Scoop.it
The immune system can be your best friend for mRNA vaccines - and also your biggest bottleneck.

A new paper in npj Vaccines by Lobb et al., highlights a counterintuitive point: type I interferon (IFN), a key innate immune alarm signal, can reduce mRNA-LNP vaccine effectiveness if itโ€™s triggered at the wrong time, because activated dendritic cells lose the ability to take up new antigen.

In their models, blocking IFNฮฑ/ฮฒ receptor signaling before vaccination (or removing the receptor specifically in dendritic cells) increased vaccine uptake/expression in DCs, improved CD8โบ T-cell priming, and led to better tumor control. They also show a practical implication: IFN already โ€œin the systemโ€ (for example after an infection or a recent prior vaccination) can blunt the response to an mRNA-LNP vaccine given shortly afterwards.

This connects directly to a theme we care about at Sensible Biotechnologies: for mRNA medicines, purity and innate immune activation are not โ€œnice-to-haveโ€ quality attributes - they can materially shape uptake, translation, and ultimately efficacy. If IFN signaling suppresses antigen acquisition and translation capacity in key antigen-presenting cells, then minimizing unnecessary innate triggers (including those driven by impurities) becomes part of the performance equation, not just the safety story.

Thatโ€™s why Sensible is focused on maximizing mRNA purity and minimizing immunogenicity as we build a vertically integrated, cell-based platform for mRNA design and manufacturing.

Youโ€™ve heard of CAR-T.
But you might not know about CAAR-T - a newer, more targeted twist on the same technology:

So what is it?
- CAAR-T (Chimeric AutoAntibody Receptor T cells) are designed to eliminate only the B cells producing harmful autoantibodies, while sparing the rest.
- Instead of using an antibody fragment to find targets (like CAR-T does), CAAR-T cells display an autoantigen on their surface, tricking autoreactive B cells into binding and revealing themselves.

Hereโ€™s how they compare:

CAR-T Cells
Advantages:
- Targets all B cells via markers like CD19
- Proven success in cancer and autoimmune diseases (e.g., lupus)
Disadvantages:
- Destroys healthy B cells too, leading to broader immune impact
- Can cause CRS, especially with large-scale immune activation

CAAR-T Cells
Advantages:
- Precisely targets only B cells producing harmful autoantibodies
- Spares healthy B cells, preserving immune function
Disadvantages:
- Requires known autoantigen (e.g., Dsg3, MuSK)
- Limited clinical experience, still early in development

In short:
CAR-T is broad and proven.
CAAR-T is precise and emerging.

Now, I don't see CAAR-T replacing CAR-T.

But for autoantibody-driven diseases, it could offer something weโ€™ve never had before:
A precise strike against the root cause, without wiping out the entire immune arsenal.
