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.
These agents simultaneously bind to a tumor-associated protein on cancer cells and the CD3 protein on T-cells, facilitating a targeted anti-cancer immuneresponse. When we look at how TCEs interact with targeted cancer cells we can quickly see how cancers respond to T Cell-based therapies.
These types differ in their etiology, natural history, and present distinct challenges in disease management. 2 Unmet needs in lung cancer treatment Recent decades have seen significant advancements in lung cancer treatment, especially with the introduction of targeted therapies and immunotherapies, which have notably improved survival rates.
In most cancers, the tumour evolves by acquiring mutations that confer growth advantages or resistance to therapies. These newly formed mutated proteins are called neoantigens and they are only present on tumour cells and are not found in normal, healthy cells. Neoantigens are recognised as non-self and trigger an immuneresponse.
Last week DNA Science covered a setback in a clinical trial of a gene therapy for Duchenne muscular dystrophy (DMD). Also recently, FDA’s Cellular, Tissue, and Gene Therapies Advisory Committe turned down a stem cell treatment for amyotrophic lateral sclerosis, aka ALS, Lou Gehrig’s disease, or motor neuron disease.
Over the past 25 years, T-cell therapies have gained significant ground in the treatment of cancer.

We are in an era of immuno-oncology (IO) revolution with many approved therapies now available to treat a broad range of cancers. Generally, IO has been focused on harnessing the anti-tumour activity of certain cancer-fighting T-cells , a key cell type involved in the adaptive immune defense system.
A potential game-changer in medicine The implications of this research are vast, potentially transforming the way we treat a variety of diseases involving both the immune and nervous systems. In the absence of IL-31, these nerve cells failed to control the immune system, leading to unchecked inflammation.
An important limitation of antibodies against tumour antigens is that these agents direct responses to molecular targets present on the surface of the cell. Figure 1: HLA Class I presentation of peptides derived from intracellular antigens. However, most of these peptides may also be presented by normal cells.
