Soon after its publication, scientists, journalists, and investors were revisiting ‘phage therapy’ as a promising alternative to our failing antibiotics. Read it on our website here. Illustration by David S. Fast forward to 2023.
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).
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.
Cell and gene therapies (CGTs) have made significant advancements in treating oncological diseases, with therapies like CAR-T cell treatments transforming cancer care. However, cell-based therapies are intended to leverage those healthy cells via transplant to regenerate damaged tissue.
The combination of P1 with antiPD1 more efficiently activated innate and adaptive immuneresponses than either P1 or antiPD1 alone by re-energising T cell effector functions, thus providing the remarkable reduction of tumour growth in solid tumours and extended survival period.
Over the past 25 years, T-cell therapies have gained significant ground in the treatment of cancer. Preclinical research on γδ T cells has made great strides since the cells were first identified in the 1980s, with γδ T-cell therapies from several companies, including IN8bio, now in or nearing clinical trials for various cancers.

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. “In Induction of innate immunity was investigated via specific cytokine markers.
In the final chapter of my 2012 book The Forever Fix: Gene Therapy and the Boy Who Saved It , I predicted that the technology would soon expand well beyond the rare disease world. Gene therapy clearly hasn’t had a major impact on health care, offering extremely expensive treatments for a few individuals with rare diseases.
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.
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. We are studying the placement of organelles within cells and how they communicate to help better treat disease,” said Coskun.
His mother had a presentation of the disease that suggested her immune system was already on the job. But immunotherapy was not yet widely used and had not been applied clinically to Merkel cell carcinoma, so she received traditional chemotherapy and radiation therapy, suffering life-threatening complications along the way.
In most cancers, the tumour evolves by acquiring mutations that confer growth advantages or resistance to therapies. 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.
It suggested that, in the future, certain classes of drugs, specifically genetic therapies, could be screened entirely virtually via models of life. Models trained on nucleotide data were ideal for understanding how genetic therapies altered cellular dynamics, so they powered the genetic editing revolution.
The experience showed me that new therapies are needed not only to meet the targets laid out by the End TB Strategy but also to prevent drug resistance from negating the effectiveness of current therapeutics. Testing the engineered cells against four common drugs, I found that the M. tuberculosis.
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.
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.
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.
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.
These connections provide all-too-important ‘reasons to believe’ for further investment and movement into earlier lines of therapy. However, despite this long winter, new approaches, ranging from CD3 bi-specifics, to cell therapies, to cancer vaccines, and more recent novel intracellular mechanisms have started to turn the tide.
The applications of mRNA-based therapies in cancer research represent one of the next groundbreaking steps toward improved cancer treatments. Adoptive T Cell therapies, therapeutic antibodies, and immunomodulatory proteins represent just some of the potentially beneficial treatment strategies for successful mRNA cancer trials.
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.
With further research, these innovative nanoparticles could represent a major breakthrough in the fields of gene therapy and personalised medicine. The researchers are optimistic that, with additional improvements, these nanoparticles could be used as an inhalable therapy to treat a range of lung ailments, including cystic fibrosis.
