Using single-cell RNA sequencing to analyze gene expression in individual cells, the researchers have found how 86 major cytokines affect 17 immune cell types in mice. NH: This is the first single-cell resolution dictionary of each major immune cell type responding to each major cytokine in vivo at an unprecedented scale.
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.
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…
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.
Among the many remarkable components that make up this complex defence network, T cells have emerged as powerful guardians, orchestrating an array of immuneresponses with great precision.

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.
The drugs work by blocking a protein, PD-1 — which helps keep immuneresponses in check — and stimulating the immune system to attack tumors. The team studied the immuneresponse to CRISPR and designed a new technology that they published in 2021 — a way of removing immune-triggering molecules from CRISPR-edited cells.
In research published in Scientific Reports , 1 investigators focused on mesenchymal stem cells (MSCs), known for their potential in treating cell defects and regulating immuneresponses.
These neoantigens are identified by T cells of the immune system as foreign proteins and thus trigger an immuneresponse. Neoantigens are recognised as non-self and trigger an immuneresponse.
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. His mentorship produced numerous publications.
These peptides are a vital part of the immune system’s display-recognition mechanism that enables T cells to distinguish between self and non-self-antigens, recognizing intruders to initiate immuneresponses.
The new viruses could shuffle surface antigens after encountering an immuneresponse, rapidly adopt new conformations to fit through tight cellular junctions, and self-replicate at safe background levels for years on end. Prior therapeutic viruses had had their replication capabilities crippled out of fear of severe immuneresponses.
Treatment with mIDH1 blockers unearths these remnants, triggering an immuneresponse against the tumor cells. This immuneresponse relies on the expression of a gene called cGAS , which produces part of a protein that detects retroviruses.
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.
2D cell models are often engineered to over-express the target of interest and so lack its temporal behaviour in its native or disease state. This is particularly pertinent in immune-based cell therapies like CAR-T, where animals do not mimic the human immuneresponse.
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. With convergent technology, it is possible to engineer monoclonal antibodies that mimic the specificity of TCRs for tumour‑specific pHLA targets.
Take Janux Therapeutics, a biotech focused on developing immunotherapies that generate tumor-specific immuneresponses to attack and kill tumors without destroying a patient’s healthy tissue. While early, these data demonstrate clear promise to advance this modality.
We are hopeful that it can be used to treat or repair a range of genetic diseases, including cystic fibrosis,” said Daniel Anderson, a Professor in MIT’s Department of Chemical Engineering and a member of MIT’s Koch Institute for Integrative Cancer Research and Institute for Medical Engineering and Science (IMES).
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.
Merck will select cancer targets and harness Janux’s proprietary Tumor Activated T Cell Engager (TRACTr) technology to engineer novel, T cell engager drug candidates. Janux technology can be applied to immunotherapies that target all three stages of an anti-tumor immuneresponse.

NK cells are among the front line of protection from infected and abnormal cells as part of the ‘innate immuneresponse’. They recognise ‘cell stress molecules’ on the surface of infected, old, injured and cancerous cells without the need for complex pre-stimulation signals of the adaptive immune system (eg, T cells).
The idea to redirect an immuneresponse against a pathogen to fight cancer goes back to 1891, when Manhattan bone surgeon William Coley became intrigued by a man’s neck tumor that melted away after he contracted a nasty Streptococcus skin infection. The fishy strategy is both fast and patient-specific.
These include engineering the cells to express cytokines that promote their maturation and/or differentiation, and engineering drug-resistant γδ T cells that can be combined with chemotherapies, which stress cancer cells but would otherwise also deplete the T-cell population. References Fichtner A, Ravens S, Prinz I.
This is particularly beneficial for those who need chronic transfusions and are therefore at risk of developing an immuneresponse to transfusion products from other people, or for those with religious beliefs, like Jehovah’s Witnesses, whose faith prohibits blood transfusions from another person.
