Immunotherapies, which mobilize the body's immune defenses against a cancer, have not been effective for GBM, in part because the tumor's surrounding environment is largely impenetrable to assaults from the body's immune system.
The immune system can carry out many biological processes, from killing viruses to fighting cancer, thanks in large part to approximately 100 key cell-signaling proteins called cytokines, which instruct immune cells what to do. For many immune-mediated diseases, there's no cure or treatment. Did any results surprise you?
When faced with a viral threat, bacterial cells developed an immuneresponse by capturing and copying DNA fragments of viruses. It was also discovered that the Cas enzyme was responsible for DNA cleavage. Today, however, we will explore a different application of CRISPR: microbiome engineering…
In a new development, a recent paper published in Biology Methods & Protocols by Oxford University Press has highlighted a promising avenue for enhancing vaccine efficacy against infectious pathogens like the COVID-19 virus. The role of extracellular vesicles in COVID-19 virus infection [Internet]. Available from: [link]
Better activation of innate and adaptive immuneresponses was achieved with CV2CoV, resulting in faster response onset, higher titers of antibodies, and stronger memory B and T cell activation as compared to the first-generation candidate, CVnCoV.
Genome engineering and gene therapies that manipulate DNA sequences in cells have driven a biotechnological revolution over the past decade. 1 Adeno-associated virus (AAV) vectors are the leading platform for in vivo gene delivery for the treatment of various human diseases. His mentorship produced numerous publications. e419 (2023).
The molecular tools of CRISPR were borrowed and developed from the natural immuneresponse of bacteria to viruses – bacteriophages – that infect them. A recent paper in BioDesign Research , CRISPR-Cas-Based Engineering of Probiotics , from investigators at several Chinese research institutions, contributed to the report.
To deliver CHARM throughout the brain, the team collaborated with scientists in the lab of Ben Deverman , senior director of vector engineering at the Broad and a co-author of the study. They used an engineered adeno-associated virus (AAV) that crosses the blood-brain barrier after intravenous administration.
On the surface, they hadn't deviated much from the early 2020s: a virus infected a cell and released the genetic therapy hidden within. Dozens of diverse chemical markers and de novo , evolutionary distinct proteins littered the virus' surface, indicating a previously unseen biological logic.
Targeted drug treatment leads tumor cells to imitate viral infection By Ari Navetta July 11, 2024 Breadcrumb Home Targeted drug treatment leads tumor cells to imitate viral infection Exploiting "viral mimicry," mIDH1 inhibitors trick tumors into thinking they are infected with a virus.
Each T cell expresses a TCR specific for an HLA‑presented peptide signal, and when that signal is detected a T cell expressing the relevant TCR can launch a complex array of immune effector responses that can suppress or destroy tumours or virus-infected cells. Many potential candidate antigens are under consideration.
These neoantigens are identified by T cells of the immune system as foreign proteins and thus trigger an immuneresponse. Recognition of bacteria, viruses and fungal invaders as ‘foreign’ makes sense, but how does the immune system recognise cancer cells as a threat?
This sugar-coated mucin binding to checkpoint receptors signals that the cancer cell poses no threat, consequently blocking the immuneresponse. Tender elaborated that these results in immune cells ignoring the cancer rather than eliminating it, as they normally would.
Melody Swartz, Jeffrey Hubbell and colleagues had previously developed a vaccine delivery tool called polymersomes – self-assembling, spherical nanoparticles that can encapsulate antigens and adjuvants (helper molecules that boost the immuneresponse) and then release them inside immune cells.
Can they deliver healing genes without triggering an overactive immuneresponse? The details are disturbingly reminiscent of the famous case of Jesse Gelsinger , who died from a ferocious immuneresponse to experimental gene therapy in September 1999. An immuneresponse is two-tiered.
doi: 10.2210/rcsb_pdb/goodsell-gallery-048 The Virus that Cures It’s been over 25 years since the science magazine Discover first ran an extraordinary article about how a long-forgotten medical treatment, used in the former Soviet country of Georgia, could save us from the growing threat of untreatable, drug-resistant infections.

The pre-clinical animal trials of the intranasal vaccine showed a reduction in both the impact of the disease itself and transmission of the virus. This should prevent both clinical disease and virus transmission, to halt the spread of the COVID-19 pandemic.
The decoy is a specially engineered protein particle that mimics the 3D structure of the ACE2 receptor , a protein on the surface of our cells that the virus’s spike proteins bind to as the first step in causing an infection. In the lab, it also appeared to neutralize the virus as well as monoclonal antibodies used to treat COVID-19.
We had built a machine learning classifier that has been trained to identify amino acid sequences that have the potential to mimic ‘host defense peptides’ from the human innate immune system. Such peptides play a critical role in the machinery for amplifying innate immuneresponses. This work can potentially help with that also.
Tissue engineering techniques using induced pluripotent stem cells (iPSC), which are differentiated into cardiomyocytes, are being developed to create functional cardiac tissues from patient-derived cells. While commonly used, AAVs have limitations, including immune reactions and difficulties with re-dosing due to pre-existing antibodies.

Breathe in, exhale.
In the study, immunization with the hAd5-COVID-19 vaccine inhibited SARS-CoV-2 virus replication in 100% (10 of 10) of Rhesus macaques, with a drop in viral replication starting on the first day of vaccine administration, and undetectable viral levels as early as three to five days post-challenge in most of the animals.
Blocking an immuneresponse-related enzyme holds promise in preventing or treating severe COVID-19 symptoms by reducing inflammation, tissue injury and blood clots in the lungs, new research in mice suggests. Previous research has shown that caspase 11 in mice has many of the same immune-response functions as caspase 4 in humans.
NVX-CoV2373 is a vaccine candidate engineered from the genetic sequence of SARS-CoV-2, the virus that causes COVID-19 disease.

After injection of such a vaccine, the mRNA instructs cells to produce proteins designed to stimulate an immuneresponse against these same protein targets when they show up in viruses or in tumor cells. Adoptive T Cell Therapies Adoptive T cell therapy is another form of cancer treatment leveraging the patient’s immune system.
It would also be undetectable by key parts of the human immune system. Some scientists even think it had a virus defense system; “researchers say LUCA likely housed 19 CRISPR genes, which bacteria use to slice up viral threats,” reports Quanta Magazine.
“These data show consistent, high levels of efficacy and reaffirm the ability of the vaccine to prevent COVID-19 amid ongoing genetic evolution of the virus. Variant Virus Strains. It was generally well-tolerated and elicited robust antibody response in Phase 1/2 clinical testing. against the original virus strain, 86.3%
Upon binding, the antibodies block the spike protein from interacting with ACE2 and thereby prevent virus-induced cell-killing, also known as cytopathic effect. Headquartered in Mountain View, California, IGM Biosciences is a clinical-stage biotechnology company focused on creating and developing engineered IgM antibodies.
Many of the elderly patients who survived the virus were poor: not exactly the demographic you would expect to fare well in a health crisis. This is how many medical studies begin, said biomedical engineering professor Phil Bourne, who serves as founding dean for the School of Data Science.
