How Smart Drug Delivery Systems Work in Autoimmunome Diseases

Te patofizjologiczne of autoimmunologiczne choroby provides natural cues that SDDS can exploit. For instance, invested synovial tissue in reutitis arthretis has a lower pH (EFIS 6.0- 6.5) than normal tissue (EFIS 7.4), while multiple sclerosis lesions exhibit elevated levels of matrix metalloproteinase. Smarts carries are difficered to respond to these unique signals.
