Manguso, who’d recently graduated from college and was conducting research at the University of Copenhagen as a Fulbright scholar, moved back to the Boston area to be with his mother as she underwent treatment. Omar Avila Monge puts samples — immune cells isolated from tumors treated with the PTPN2 inhibitor — into a centrifuge.
During the process of transformation from a normal cell into a cancer cell, a cell acquires a series of changes, or mutations, in its DNA. But DNA mutations can also result in changes to the proteins that are displayed on the surface of the cancer cell. Neoantigens are recognised as non-self and trigger an immuneresponse.
New researched published in the journal Immunity , T cells exhibit an unusual, yet vital behaviour in their battle against pathogens and cancer cells, involving a nuclear receptor. The cell’s nucleus, containing compacted DNA, is centrally positioned within the cell.
Researchers must characterize the anti-drug-antibody (ADA) response in preclinical and clinical studies and report any ADA-positive samples as a risk-based approach. These interactions may disrupt protein function, trigger immuneresponses, or contribute to other toxicological risks.
Even after microbiologists discovered the bacterium that causes the illness in 1882, it wasn’t until the 1920s that researchers were able to develop a vaccine for TB. Chilean research participants aged 15 to 35 who received the vaccine during a case-control study , for example, only showed a 10 percent reduced risk of pulmonary TB.
There are currently no treatments, but researchers from the Whitehead Institute for Biomedical Research and Broad Institute of MIT and Harvard have developed an approach that could one day be used to turn off the gene encoding this protein throughout the brain to treat or even prevent prion disease.
Borrowed from Bacteria Researchers are using the gene editing tool CRISPR to improve upon naturally-evolved human microbiomes, to build a better probiotic. The molecular tools of CRISPR were borrowed and developed from the natural immuneresponse of bacteria to viruses – bacteriophages – that infect them.
HLA are the critical molecules that our immune systems use to present peptides to T cells and facilitate recognition and killing in immuneresponses to pathogens. HLA-II presents peptides to CD4 T cells thought to be important for indirectly helping immuneresponses and facilitating antibody production.
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. million DNA bases. Muscles stop working.
The research community pressed on, turning to novel compounds that were substantially more potent than those used in the first generation. 2 In response, DNA-damaging agents that could target the entire cell cycle received renewed attention as ADC payloads.
Allison Berke makes the case for real-time DNA sequencing and AI tools to detect pathogens before they spread widely. Reading DNA The first step in detecting a novel pathogen is recognizing it as an anomaly amidst a noisy background of other material. After copying the DNA to form a big pool, each piece is sequenced.
Reporting in Science , researchers at Massachusetts General Hospital and the Broad Institute of MIT and Harvard have made a surprising discovery about these drugs. They found that mIDH1 inhibitors trick the tumor cells into thinking they are infected with a virus, causing the immune system to mount an antiviral response.
Natural killer (NK) cells are another immune cell type that, as the name suggests, also have potent cell-killing activity, and have a well-known role in the anti-tumour immuneresponse. In the context of a tumour microenvironment, Tregs are often present in high numbers, preventing an effective immuneresponse to the tumour.
Gene-editing methods allow researchers to modify DNA, resulting in alterations in physical characteristics such as eye colour and susceptibility to diseases. To achieve this, scientists utilise various technologies that function similarly to scissors, precisely cutting the DNA at a particular location.

Researchers from the Laboratory of Bacteriology at The Rockefeller University have now found that bacteria sense phages by a defensive response named CBASS (cyclic oligonucleotide-based antiphage signalling system) which detects viral RNA. In bacteria , cGAS-like cyclases are central parts of the CBASS immuneresponse.
This exclusive interview with Dr Sharon Benzeno, Chief Commercial Officer, Immune Medicine at Adaptive Biotechnologies, unveils some ground-breaking research on T- cell therapy for cancer , which has seen the first TCR-based therapeutic candidate progress to clinical development, offering promising advancements in innovative cancer treatments.
Researchers from Harvard Medical School describe a new ChatGPT-like model that can guide clinical decision-making to diagnose, treat, and predict survival for several types of cancer. This removes the cancer’s blocking of the immuneresponse, so that T cells can fight the cancer.
Unlike almost every other cell type (except B cells), T cells do not have the exact same chromosomal DNA sequences as other cells in the body. To be therapeutically useful, antigenic peptides must be presented in a way that allows immuneresponses to destroy cancer cells without causing unacceptable damage to healthy tissue.
Since cancer cells are under chronic stimulation of ER stress, the polypeptides cannot activate innate immune sensors in cancer cells even upon the polypeptide treatment. Which natural agonists impede the activation of intracellular DNA sensors in APCs, and what challenges do they pose?
Researchers would sift through natural extracts , hoping to stumble upon a compound that exhibited beneficial effects. In fact, it's one of the most exciting areas in drug research today. With billions in funding and innovative research, we're starting to see strategies that can tackle these tough targets.
A research team led by Rita Fior at the Champalimaud Centre for the Unknown, Lisbon, Portugal, figured out how BCG decimates cancer cells. However, the modern science of immunology has shown that Coley’s principles were correct and that some cancers are sensitive to an enhanced immune system. The approach worked.
Goodsell, RCSB Protein Data Bank and Scripps Research. 1 Yet even after more than two decades of research, media hype, and dozens of clinical trials and biotech start-ups that have come and gone, phage therapy has not scaled. Still, researchers are trying. Read it on our website here. Illustration by David S.
Genome engineering and gene therapies that manipulate DNA sequences in cells have driven a biotechnological revolution over the past decade. 9 In addition, host immuneresponses further add to the complexity of developing cell-specific AAV capsids for clinical applications.
Related people Paul Blainey Nir Hacohen A signaling protein known as STING is a critical player in the human immune system, detecting signs of danger within cells and then activating a variety of defense mechanisms. Because of that, the researchers wondered if STING might somehow induce proton leakage.
Advances in research and development and the utilisation of combination treatment strategies are revolutionising the haematology care landscape, but more must be done to address patients’ individual needs. These options are creating opportunities to develop more sophisticated, novel combination regimens for patients.
mRNA was the intermediate stage between DNA and protein, a dynamic entity that shifted depending on the second-to-second needs of the cell, able to point out if a cell was cancerous or stressed, what kind of cell it was, and so on. The lab created a plan with eight research institutions across three continents.
One approach currently being explored involves stimulating innate immuneresponse pathways. For example, the STimulator of InterferoN Genes (STING) pathway, which is known to play a critical role in innate immunity in response to viral and bacterial DNA, has also been shown to promote anti-tumor immuneresponses.

Microenvironment Management : Optimizing the tumor microenvironment to enhance TIL efficacy remains a critical focus of research efforts.
Everything started in school with an experiment on isolating DNA from bananas. Making a little tangle of DNA visible to the eye and understanding that this is the basis of complex organisms, which might be altered in disease, was the defining moment for my future path in life sciences. in North America) in late 2017.
Once delivered into the body, the mRNA instructs cells to produce these antigens, which are then presented to the immune system. This process triggers a robust immuneresponse, enabling the immune system to recognize and attack cancer cells. Another challenge is the potential for unintended immuneresponses.
.” CRISPRs are short DNA sequences, peppered with repeats, that latch onto DNA-cutting enzymes, commandeering and directing them to snip certain parts of a chromosome. The microbes deploy them to dismantle the genetic material of infecting viruses, a little like an immuneresponse.
Early-phase clinical trials have shown the safety and efficacy of using stem cells for cardiac repair, encouraging further research and development. While commonly used, AAVs have limitations, including immune reactions and difficulties with re-dosing due to pre-existing antibodies.
Innovations in payload substances, such as topoisomerase inhibitors (topo-1i), and next-generation DNA- damaging agents to replace older, more toxic agents. However, research and clinical trials of BiTEs in solid tumours, including NSCLC, are still in the early phases. Biomarker Research. 2024;12(1):24. Curr Probl Cancer.
Among them, adeno-associated viruses (AAVs) stand out due to their small size, high efficiency in gene delivery, low immunogenicity, and potential for customisable tissue targeting, making them the leading tool in gene expression research.
So when I was asked recently to share advice to a group of undergraduate students doing research at Penn State, I was drawn to the idea of connecting scientific principles to some life lessons. The central dogma of molecular biology is that information generally (with few exceptions) flows from DNA to RNA to Protein.
Next Generation AAVs enhance gene therapies by increasing transduction efficiency and specificity while reducing immuneresponses and cost.
