The TME has even been shown to inhibit cellular immunotherapy, a novel form of treatment in which the cells of a patient's immune system are re-engineered in the lab to attack cancer cells. Therefore, scientists are now developing cellular immunotherapies that attempt not only to promote the anti-cancer activity of the immune system, but also combat the inhibitory effect of the tumor microenvironment. While it is straightforward to assess the effect of new therapies on the cancer cells, assessing the effectiveness on the TME is challenging. https://medicalxpress.com/news/2020-07-nano-radiomics-unveils-treatment-effect-tumor.html Sat, 11 Jul 2020 02:34:35 EDT news513653669 Curtin University researchers have developed tiny capsules that are able to effectively target the liver and pancreas reducing the inflammatory effects of type two diabetes. https://medicalxpress.com/news/2020-01-tiny-nano-capsules-effective-diabetes.html Mon, 13 Jan 2020 07:29:02 EST news498122938 Researchers from the University of Liverpool and Queen's University Belfast have been awarded over £1m by the Engineering and Physical Sciences Research Council (ESPRC) to examine the use of nano-engineered microarray patches (MAPs) to enhance the delivery of long-acting HIV medicines. https://medicalxpress.com/news/2019-08-nano-engineered-microneedles-hiv-drug-delivery.html Tue, 20 Aug 2019 10:40:01 EDT news485514380 A team of researchers from Université Paris-Saclay and Université Paris Descartes has developed a nano-drug that has been found to reduce pain in rodents.

These cells interfere with the functioning of the tissue in which they accumulate. Senescence is a cellular program that is triggered by many types of damage, and senescent cells are present in many diseases. They accumulate in diverse types of tissues during aging, thus contributing to the progressive deterioration associated with becoming elderly. Eliminating these zombie cells is one of the challenges facing science today. https://medicalxpress.com/news/2018-07-nano-carrier-drugs-cells.html Fri, 27 Jul 2018 06:49:48 EDT news451892974 France's Sanofi announced Monday that it had reached a deal to acquire Belgian biotech firm Ablynx that values the firm at 3.9 billion euros ($4.8 billion), beating out Danish rival Novo Nordisk for the nano-drug maker. https://medicalxpress.com/news/2018-01-sanofi-big-nano-drug-maker.html Mon, 29 Jan 2018 04:00:02 EST news436420500 Denmark's Novo Nordisk, the world's leading insulin manufacturer, announced Monday an offer to buy the Belgian biotech firm Ablynx for 2.6 billion euros ($3.1 billion). https://medicalxpress.com/news/2018-01-novo-nordisk-woos-belgian-nano-drug.html Mon, 08 Jan 2018 10:02:50 EST news434628164 Metastatic or castrate-resistant prostate cancer can spread to the bone in certain patients.
