A study opens new perspectives to better understand how the molecular mechanisms involved in regenerative medicine work. The study focuses on tumor necrosis factor- (TNF- ) and its receptors TNFR, molecules of key interest in biomedicine due to their involvement in multiple diseases such as obesity related to type 2 diabetes mellitus, inflammatory bowel disease and several types of cancer.

Hair follicle infections are often difficult to treat because bacteria settle in the gap between hair and skin, where it is difficult for active substances to reach them. In order to investigate this scenario more closely in the laboratory, researchers have now developed a model with human hair follicles embedded in a matrix produced using 3D printing. In the future, this model can be used to test the effectiveness of new drug candidates against corresponding pathogens directly on human follicles.
