Researchers find how cancer can be killed by body s own immune system ANI | Updated: Jan 17, 2021 14:57 IST
Washington [US], January 17 (ANI): A new way to help the body s immune system get past that deception and destroy cancer, has been found by a University of Missouri researcher. Normally, your body s immune cells are constantly on patrol to identify and destroy foreign entities in the body, said Yves Chabu, an assistant professor in the Division of Biological Sciences. Normal cells put up a don t-eat-me molecular flag that is recognized by immune cells, thereby preventing the destruction of normal tissues. But some cancers have also developed the ability to mimic normal cells and produce this don t eat me signal. As a consequence, the immune system fails to recognise cancer as a defective tissue and leaves it alone, which is bad news for the patient, added Chabu.
The body's immune system is the first line of defense against infections like bacteria, viruses or cancers. Some cancers, however, have developed the art of molecular deception to avoid destruction by the body's immune system.

As ocean waters increasingly acidify due to absorbing carbon dioxide, tracking impacts on specific species has been difficult to gauge over time. Most of what is known about species responses to acidifying waters comes from short-term experiments that suggest increases in ocean acidity causing a lowering of seawater pH and less availability of carbonate ions to make shells can lead to less fortified shells and more vulnerable animals. But not every species from the studies responds the same way, with some even appearing to do better under those conditions.
Comparing new data with samples collected in the 1950s, UCSD s Division of Biological Sciences graduate student Elizabeth Bullard and Professor Kaustuv Roy found that ocean acidification is transforming the composition of California mussel shells from mostly the mineral aragonite to the mineral calcite. The results are published in the Proceedings of the National Academy of Sciences.

SAN DIEGO, CA UC San Diego scientists reported Monday that increased ocean acidity is weakening California mussel shells along the Pacific Coast, a result of rising levels of human-produced carbon dioxide.
The large mollusk known as the California mussel makes its home in the rocky shoreline from Mexico to Alaska. It is considered a foundational animal, as it provides homes for hundreds of other species and offers a rich food source for species ranging from spiny lobsters to humans.
