After taking a pill, the drugs it contains are distributed throughout the human body, reaching the tissues and cells affected by diseases and performing their intended function. However, they also enter healthy cells, where they often cause more harm than good. In a study published in the journal “Nature Communications”, a multidisciplinary team led by TUDa professors Felix Hausch from the Department of Chemistry and Alexander Loewer from the Department of Biology has now shown how proteins occurring naturally in human cells can be used to target therapeutics specifically at diseased cells.
