Advancements in gene-modified cell therapies, including chimeric antigen receptor (CAR)-T cells and T cell receptor (TCR)-T cells, show promise for treating solid tumors. Further development in personalized and universal technologies is crucial for broader application in cancer immunotherapy.
Area of Science:
- Immunology
- Oncology
- Biotechnology
Background:
- Recent immunological discoveries and gene modification technologies are driving novel cancer immunotherapies.
- Chimeric antigen receptor (CAR)-T cell therapy, a gene-modified cell therapy, has been approved by the FDA.
- Solid tumors remain a challenge for conventional CAR-T cell therapy.
Purpose of the Study:
- To review the advancements and potential of gene-modified cell therapies in cancer treatment.
- To highlight emerging strategies like 4th generation CAR-T cells and T cell receptor (TCR)-T cells targeting neoantigens.
- To discuss the potential of other immune cells and the development of personalized and universal cell therapies.
Main Methods:
- Review of current research in immunology and gene modification technologies for cancer therapy.
- Analysis of novel CAR-T cell generations and T cell receptor (TCR)-T cell approaches.
- Exploration of alternative immune effector cells and allogeneic "off-the-shelf" cell therapy.
Main Results:
- 4th generation CAR-T cells demonstrate potential in eradicating solid tumors.
- T cell receptor (TCR)-T cells targeting neoantigens offer a new avenue for cancer treatment.
- Other lymphocyte subsets (NK, iNKT, gd T cells) are being explored as gene-modified effector cells.
Conclusions:
- Gene-modified cell therapies, including advanced CAR-T and TCR-T cells, hold significant promise for cancer immunotherapy.
- Personalized medicine and universal "off-the-shelf" technologies are critical for the future advancement and accessibility of these treatments.

Cancer-Critical Genes II: Tumor Suppressor Genes
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.

What is Gene Expression?
Gene expression is the process in which DNA directs the synthesis of functional products, that is, proteins. Cells can regulate gene expression at various stages. It allows organisms to generate different cell types and enables cells to adapt to internal and external factors.
Genetic Information Flows from DNA to RNA to Protein
A gene is a stretch of DNA that serves as the blueprint for functional RNAs and proteins. Since DNA is made up of nucleotides and proteins consist of amino...
