Gene Therapy Turns Immune Cells

Breakthrough Gene Therapy Turns Immune Cells Against Cancer



A groundbreaking study led by researchers from Israel, the US, and China has developed a genetic method to reprogram immune cells, transforming them from cancer promoters into powerful tumor fighters. The findings, published by the Weizmann Institute of Science, could pave the way for new immunotherapy treatments for solid cancers.

Macrophages: The Double-Edged Sword of the Immune System


Macrophages are versatile immune cells that typically help the body fight infections and diseases. However, in many cancers, they switch sides, protecting tumors, aiding their growth, and even helping them spread.

“Macrophages are like the Swiss Army knife of the immune system—they can perform many functions, but in cancer, they’re hijacked to help tumors survive,” explained Prof. Ido Amit, lead researcher at Weizmann’s Systems Immunology Department.
Gene-Editing Breakthrough: The Zeb2 Switch

Using CRISPR-Cas9 gene editing and AI-powered single-cell analysis, the team analyzed human tumor samples and identified 120 genes linked to this harmful transformation. They discovered that Zeb2, a key gene, acts as a master switch:When active → Macrophages support cancer growth, When silenced → Macrophages revert to their natural tumor-fighting state. Further research revealed that Zeb2 alters the epigenome, turning off anti-cancer genes while activating those that help tumors thrive.

DNA Therapy Shows Promise in Shrinking Tumors


The team designed a custom DNA molecule that delivers a gene-silencing agent directly into macrophages. In mice with bladder cancer, injecting this molecule reprogrammed the macrophages, leading to significant tumor shrinkage.

Implications for Future Cancer Treatments


This discovery opens new possibilities for immunotherapy, offering a way to re-educate immune cells rather than just destroying them. The next step is human clinical trials to test the therapy’s effectiveness in cancer patients. “We’re turning the enemy into an ally—using the body’s own defenses to fight cancer from within,” said Amit.

This research could lead to more precise, less toxic cancer treatments, potentially improving outcomes for patients with solid tumors like bladder, breast, and lung cancers.

Genetics role in ovarian cancer

The Medical Minute: Genetics play big role in ovarian cancer In 2024, about 19,680 women in the United States will receive a new diagnosis of ovarian cancer and 12,740 women will die from the disease, said Dr. Shaina Bruce , a gynecologic oncologist at Penn State Cancer Institute . The median age of all patients who develop ovarian cancer is 63. Historically, women at increased risk for ovarian cancer are recommended to have their fallopian tubes and ovaries removed when they have completed having children. Taking that step to protect themselves comes at a heavy price ― surgical menopause. But Bruce said medical science is catching up with ovarian cancer. Studies could lead to new methods for preventative care and the surgery needed to lower risk may be easier than it once was. Below, during Gynecologic Cancer Awareness Month, Bruce discusses the disease and why acting to reduce your risk is worth it. What’s the connection between heredity and ovarian cancer? About 25% of all cases of ...

Multifactorial Genetic Conditions

Multifactorial Genetic Conditions Multifactorial genetic conditions are disorders caused by the combined effects of multiple genes and environmental factors , rather than a single gene mutation . These conditions do not follow classic Mendelian inheritance patterns and instead result from complex gene–environment interactions . Factors such as lifestyle, nutrition, infections, stress, and exposure to toxins can significantly influence disease onset and severity in genetically susceptible individuals. Common examples include diabetes, cardiovascular diseases , neural tube defects, asthma, and many neuropsychiatric disorders. Understanding multifactorial inheritance is essential for risk prediction, preventive medicine, and personalized healthcare strategies. Multifactorial inheritance, polygenic traits, gene–environment interaction, complex diseases, genetic susceptibility, environmental risk factors, non-Mendelian inheritance, disease predisposition, polygenic risk score, precision ...

X chromosome

Gene on the X chromosome may help explain high multiple sclerosis rates in women Brain inflammation may be fueled by a gene on the X chromosome, a new study in mice suggests. And in female mice, who carry two X chromosomes, a diabetes drug called metformin may work to counteract that inflammation. If these findings bear out in later studies, they could help to unravel the long-standing mystery of why women, who have two copies of this inflammation-driving gene, are more prone to certain autoimmune diseases, particularly after menopause. A disparity between the sexes Our bodies are patrolled by immune cells that provide protection against bacteria and viruses, but sometimes, these defenses turn on us. In the autoimmune disorder multiple sclerosis (MS), for instance, the immune system attacks myelin, the fatty insulation surrounding the nerve fibers in the brain and spinal cord. This leads to symptoms such as muscle weakness and difficulty walking, as well issues with memory and thinking...
