How cancer cells may be using ribosomes to hide from the immune system
A ribosome, its different parts depicted in different colors. Ribosomes are the protein factories of our body’s cells. Credit: Netherlands Cancer Institute The protein factories of our cells are much more diverse than we thought they were. Scientists from the Netherlands Cancer Institute have now shown that cancer cells can use these ribosomes to boost...

Reprogramming cancer cells to attack themselves
September 16, 2024 by Bob Yirka , Medical Xpress cDC1 reprogramming progresses in human cancer spheroids. Credit: Science (2024). DOI: 10.1126/science.adn9083A team of health and medical researchers affiliated with a host of institutions across Sweden has tested the possibility of reprogramming cancer cells into cDC1 cells as a means for destroying the protective shield around...

Cancer cells may be using lipids to hide from the immune system
September 9, 2024 by Katherine Fenz, Rockefeller University Glycosphingolipids (in pink, via Cholera Toxin B) are so critical for cancer immune evasion that certain cancer cells cannot proliferate without it. Credit: Rockefeller UniversityCancer cells seldom start off stealthy. Quite to the contrary, they announce their presence to the immune system by planting chemical red flags...

Light-activated macrophages show increased appetite for cancer cells
August 12, 2024 by University of California – Santa Barbara Credit: Pixabay/CC0 Public DomainThe body has a veritable army constantly on guard to keep us safe from microscopic threats from infections to cancer. Chief among these forces is the macrophage, a white blood cell that surveils tissues and consumes pathogens, debris, dead cells, and cancer....

How early-stage cancer cells hide from the immune system
A new study finds precancerous colon cells turn on a gene called SOX17, which helps them evade detection and develop into more advanced tumors.Peer-Reviewed Publication MASSACHUSETTS INSTITUTE OF TECHNOLOGY CAMBRIDGE, MA — One of the immune system’s primary roles is to detect and kill cells that have acquired cancerous mutations. However, some early-stage cancer cells...

New technique could make human T cells 100 times more potent at killing cancer cells
by Northwestern University Credit: Pixabay/CC0 Public DomainScientists at the UC San Francisco (UCSF) and Northwestern Medicine may have found a way around the limitations of engineered T cells by borrowing a few tricks from cancer itself. By studying mutations in malignant T cells that cause lymphoma, they zeroed in on one that imparted exceptional potency to...

MOLECULAR JACKHAMMERS RUPTURE CANCER CELLS
POSTED BY TEXAS A&M UNIVERSITY“From the medical point of view, when this technique is available, it will be beneficial and less expensive than methods such as photothermal therapy, photodynamics, radio-radiation, and chemotherapy,” says Jorge Seminario. A new technique could offer a much safer and more effective alternative to current cancer treatments. Just as jackhammers can...
