Understand The Research Of The Cellular Therapy Center At USP That Has Just Made A Discovery That Promises To Revolutionize Cancer Treatment.
A light shines in the fight against cancer, especially those that affect the blood.
Through an innovative research, the study identifies key proteins that can optimize the effectiveness of CAR-T cell-based immunotherapy, a promising method that still seeks greater accuracy. The revelation of these 14 proteins opens a new path for more precise and effective therapies.
USP Research: Identifies Key Proteins For CAR-T Immunotherapy
The research conducted by John Oluwafemi Teibo, a PhD student at the Ribeirão Preto Medical School (FMRP-USP), under the guidance of Professor Vitor Faça, represents a monumental advancement in the molecular understanding of CAR-T therapy.

Published in the renowned Journal of Proteome Research, the USP study identifies key proteins that operate behind the scenes of immunotherapy, directly influencing the patient’s response.
The CAR-T cell therapy (Chimeric Antigen Receptor T-cell) is one of the most promising frontiers in cancer treatment, especially for leukemias and lymphomas that affect the blood.
In this therapy, the patient’s own defense cells (T lymphocytes) are collected, modified in the lab to recognize and attack cancer cells, and then reinfused into the body.
Despite its impactful results in many cases, the effectiveness of CAR-T therapy still varies among patients, and the complete molecular mechanisms behind its success or failure were not fully understood.
It is exactly this gap that the research from USP aimed to fill, utilizing cutting-edge approaches in proteomics and mass spectrometry.
Key Proteins: New Targets For Cancer Treatment In The Blood
The USP team meticulously analyzed the biological processes during CAR-T therapy and managed to identify 14 key proteins that could serve as therapeutic targets.
Understanding the role of these molecules opens up a range of possibilities to enhance the cancer treatment in the blood, making immunotherapy more effective and predictable.
The identified proteins were classified into four main categories, each with its specific function in the complex landscape of immune response and interaction with tumor cells:
- Cytokines: Molecules that act as messengers between cells, coordinating the immune response. Examples include gamma interferon and CCL3, which are crucial in the communication and activation of defense cells.
- Kinases: Enzymes that play a vital role in cellular signaling, controlling various processes including cell growth and differentiation. The research pointed to kinases such as LCK, ITK, JAK2 and B-Raf, which can be manipulated to enhance the action of CAR-T cells.
- Receptors: Proteins located on the surface of cells that receive signals from the environment. The identification of receptors such as CD80 and CD20 may guide the development of new approaches to target CAR-T cells to cancer.
- Proteases and Chemical Messengers: Enzymes that break down other proteins and substances that transmit information between cells. Highlights include Granzyme B and TNF-α, which are essential in destroying cancer cells and in the inflammatory response.
Diving deeper into the knowledge of these molecules through proteomics, which studies the set of proteins in an organism, and advancements in mass spectrometry, which allows the identification and quantification of these proteins, is a huge step.
This detailed understanding will enable scientists to go beyond surrogate biomarkers, such as gamma interferon and IL-2, which are currently used but do not provide a complete view of the complexity of the therapy response.
The Future Of Research And The Impact On Cancer Treatment
The discovery by USP has transformative potential for cancer treatment. By identifying key proteins, researchers open doors for the development of:
- Combined Therapies: The combination of CAR-T immunotherapy with drugs that modulate the activity of these proteins may increase the success rate of the treatment.
- More Accurate Biomarkers: The proteins may serve as more precise biomarkers to predict which patients will respond best to CAR-T therapy, avoiding unnecessary or ineffective treatments.
- New Cell Engineering Strategies: With knowledge about these proteins, it is possible to design even more effective CAR-T cells with fewer side effects.
Cancer is a complex disease, and every new research that unravels its mechanisms is a crucial step toward finding a cure.
The work of USP reinforces the excellence of Brazilian science and its fundamental role in advancing global medicine, offering real hope for patients fighting against cancer in the blood and paving the way for a future with more effective and personalized treatments.
